INTRODUCTION

W ARNING! Installation of this appliance m ust be m ade in accordance withthe written instructions provided in this m anual. No agent, representativeor employee of Suburban or other person has the authority to change,m odify or waive any provision of the instructions contained in thism anual.

This manual is intended to fam iliarize the installer, servicem an and user withthe installation, operation and maintenance of the heating and cooling unit.

The unit is designed for a wall thickness of 1" m inimum to 14-1/2" maxim um .NOTE: Maxim um wall thickness cannot exceed 12-5/8" if rear gas hook-up isto be used. The wall sleeves must be installed as illustrated in Figures 5 or 6so that the unit chass is when slid into the sleeve is vented to the outsideatm osphere.

Do not install in an alcove or recess.

Special sleeve and grille applications must be brought to the attention ofSuburban as they m ay impair the operation of the unit.

IM PORTANT: Installation of the rear grille m ust be m ade prior to installingthe chassis as it secures from inside the wall sleeve.

In the U.S.A., this appliance must be installed in accordance with local codesand regulations. In the absence of local codes and regulations, installation m ustcom ply with the latest edition of:

1. National Fuel Gas Code ANSI Z223.1.2. National Electrical Code ANSI/NFPA No. 70.

In Canada, the installation m ust be in accordance with local codes or in theabsence of local codes, with the current CANI-B149 Installation Code.

Requirem ents for installations in Com m onwealth of Massachusetts, Seepage 19.

1. W hen choosing a location for the sleeve, rem em ber that the unit chassism ust be vented to the outside atm osphere, therefore, the s leeve must bem ounted in the outside wall of the room . A location should be selected withconsideration for circulation of discharge (room) air. Generally, the locationwhich provides the most effective circulation is m idway along the wall of theroom the unit is to serve and away from a stairwell or other openings. Do notlocate sleeve behind a door or at a point where a door, if left open, would tendto obstruct the unit when installed into the sleeve.

2. In choosing a location for the sleeve, one must consider the m inim umoperation clearances as specified in Table 1. These clearances assureadequate accessibility for servicing and proper operation of the unit andtherefore, must be maintained.

3. The wall sleeve may be installed directly on fin ished floor as illustrated inFigure 2, however, considerations should be given to the location of gas linesand electrical service. NOTE: If mounted on top of floor, the gas connectionshould be made from rear of unit. For the best finished results, Suburbansuggests the wall sleeve be mounted a m inim um of 3-1/2" off of the finishedfloor, as illustrated in Figure 3. This allows sufficien t space for the gas andelectrical connections to be m ade below the wall case. An accessory basepanel, Suburban Kit #520873, m ay then be attached to the cabinet front toconceal these service connections. NOTE: This base panel is non-loadingbearing.

4. W hen installing below a window, the installer should consider the possibilityof curtains interfering with discharge air and/or accessory air discharge packageand take steps to elim inate these restrictions.

5. The ins taller should allow for drywall or other interior wall finishes whenlocating sleeve during rough-in. (See Figures 5 or 6.)

6. Prior to installing the wall sleeve, one must consider the m ethod to be usedto drain the condensate from the wall sleeve. Two methods m ay be used:

a. Free Drain (External)- A general acceptable alternative where thecondensate drains from the wall sleeve through three exterior drainholes and drops to open ground. (See Figure 4.) T he condenser fanis designed to p ick up norm al condensate and evaporate it offthe condenser coil.

b. Drain Kit - A condensate drain kit is recom m ended for positive drainagewhen specified or code requires or when condensate is heavy underconditions of extrem e hum idity for extended periods of tim e. The drain tubeassem blies m ay be installed externally on rear flange of the wall sleeve orunderneath the wall sleeve to the external side of building. (See Figure 7)The condensate can be freely drained to ground level or routed in tubing toa disposable location. Drain tube kits are des igned for 1/2" O.D. coppertubing.

NOTE: Excessive rain water entering the unit through the outside grille may notbe entirely rem oved during operation of the unit. Excessive rain water will drainthrough the raised weep holes provided on the rear of the wall sleeve.

7 . A fter selecting a location for wall sleeve, inspect the wall and floor areas todeterm ine that there are no hidden electrical wires, propane or other flam m ablegas-liquid piping or tubing, ducts, girders or wall studs that will interfere with theproper installation and safe operation of the unit or the proper installation of gassupply lines and electrical service

8. The cabinet front is shipped with the unit chassis. Side flanges on chassisare secured to sleeve from inside room to insure proper security and mounting.

INSTALLATION

Before beginning the installation, it is suggested that the cabinet front and airfilter be rem oved to avoid dam age during installation of the unit.

1. Cut an opening in the outside wall and fram e to the m inim um opening asillustrated in Figures 2 or 3. Refer to Table 1 for m inimum clearances toobstruction. Use conventional construction methods to fram e opening. Do notuse wall sleeve as a lintel. The fram ed opening should allow for the slopingof the sleeve toward outside wall as illustra ted in F igures 5 or 6, in order toassure proper drainage. Do not install wall sleeve level or slope towardroom .

2. Unfold the sides of the wall sleeve and assem ble the top, being sure that thesides wedge between the top flange on the top and the retaining angle asillustrated in Figure 4. Secure at top corners w ith screws provided. If theopening in the rear of the sleeve for rear gas hook-up is not used, you m ayblock the opening using the bird guard supplied with the sleeve. (See Figure4A for illustration.)

3. Install wall sleeve into fram ed opening with the three drain holes to theoutside. Minim um projection of wall sleeve into the room is flush with finishedwall or molding, as illustrated by “x” dim ension in Figures 5 or 6.

CAUTION: Be sure sleeve protrudes far enough into the room to allow forany interior wall studding, insulation and dry wall or finished wall to beadded during construction.

Do not install sleeve flush with finished exterior wall.

Figure 2

Figure 3

If sleeve installed with floor clearance from 0" to less than 3-1/2", the sleevem ust protrude a m inim um of 1-5/8" beyond finished surface of exterior wall.(See Figure 5.) This is to allow for rear gas hook-up. If sleeve is installed withfloor clearance of 3-1/2" or greater, the sleeve m ust protrude a m inim um of 1/4"beyond finished surface of exterior wall. (See Figure 6.)

NOTE: W all sleeve installations that protrude into the room 4" or more requirethe use of Leg Leveling Kit #520600 or other m eans of supporting the wallsleeve. (See Figure 8). Failure to support the wall sleeve front in suchinstallations may cause im proper sleeve slope(1/4" rear s lope required - seeStep 4 below), which m ay result in im proper condensate leakage into theinterior room space.

For installations in windows and/or curtain or panel walls of 2", it is suggestedthat a m inim um of two field supports be installed under wall sleeve since noscrews can be used in bottom of sleeve to the wall.

Field supplied wall sleeve angles 1" x 1" x .065/.055 are to be used on top,sides and bottom of wall sleeve. (See Figure 9).

CAUTIO N: Do not drill holes in bottom of sleeve. Bottom angle is forsupport only and is to be secured to wall.

4. Secure wall sleeve to wall as illustrated in Figures 5 or 6. Be sure wall caseis level (side to side-parallel to floor) and sloped 1/4" from front to rear. Do notput holes in bottom of sleeve, water dam age to wall and floor will occur.

5. Caulk around wall sleeve between the sleeve and building to form a weathertight seal against rain and snow. Use only weather proof caulking. (SeeFigures 5 or 6).

6. Seal around sleeve between finished interior wall and sleeve to m inim izeheat/cooling loss around sleeve. Seal may be caulking, or if preferred, installerm ay trim around sleeve with m olding or other suitable m aterials.

IM PORTANT: Installation of the rear grille m ust be m ade prior to installingthe chassis as it secures from inside the wall sleeve.

7. Slide unit into wall sleeve and secure it to s leeve using the four #10 x 1/2screws provided.

8. Connect gas and electrical supply. Refer to Figure 10 for centerline locationof gas connection and electrical connection when unit is installed into wallsleeve.

NOTE: This unit is factory set for 230 volt operation. If you wish to operate uniton 208 volts, the rocker switch located behind the cabinet front on the controlspanel (reference Item No. 25, Figure 15) must be switched to 208 volts.

NOTE: On occasions, the voltage on a 230 volt model may drop. If the voltagedrop is at or below 208 volts, the switch should be switched to 208 volts.

9. The operation of this unit is controlled by a built-in therm ostat. A d ig ita ltem perature read out will be displayed on the control panel.

For rem ote therm ostat operation, connect the therm ostat wiring to the term inalblock located on the m odule board. Move switch #1 on the therm ostat switchto "on". (See Figure 12.)

To reset controls, turn power off then back on.

NOTE: Connecting rem ote therm ostat overrides the built-in therm ostat and youwill not get a digital read out on the control panel. There is no need todisconnect the built-in therm ostat as shipped from factory.

10. Reinstall air filter.

11. Reinstall cabinet front. Do not operate unit with cabinet front rem oved.

MAKING GAS CONNECTIONS

The unit is factory equipped with a 3/8" NPT gas connection. The size of thepipe should be computed according to the type of gas and the length of the run.Table 2 gives a reasonably accurate size for the service line. The quantitiesgiven in the table are for cubic feet per hour. To convert BTU capacity to cubicfeet, divide total BTU load by the BTU value of the gas being used. The tableis for natural gas only. To convert to liquefied petroleum (LP) gas, multiply by.633. The pressure drop caused by other gas appliances being served by anyportion of the line provided for this installation m ust be considered. If the newline is takeoff from an existing line to another app liance, pressure dropcomputation with the table must include the demand of the other appliance.

CAUTION: Suburban does not recomm end the use of flex tubing to m akethe gas connections to the unit unless the flex tubing is a high qualitystainless certified by AGA and approved for use by local codes.

Minimum gas supply pressure for purposes of input adjustment:

M inim um M axim umNatural Gas 5" W .C.* 7" W .C.Liquefied Petroleum (LP) Gas 11" W .C. 13" W .C.(*W ater Colum n)

Operating Pressure

All units for burning natural gas are equipped with a valve having a built-inregulator preset at 3.5" W .C. pressure. A ll units for burning liquefied petroleum(LP) gas are equipped with a valve having a built-in regulator preset at 10.5"W .C. pressure. Do not adjust the regulator set screw on the valve. Over firingof the unit may occur.

It is recom m ended that the installer install a m anual shut-off valve in the gassupply line to the unit. It is also recom m ended that a ground join t union beinstalled between the unit and this shut-off valve.

A condensate trap should also be installed in the gas supply line as close to theunit as possible.

In order to maintain a check on gas supply pressure to the unit, Suburbanadvises the installer to provide a 1/8" NPT plug tap for test gauge connectionimm ediately upstream of the gas supply connection to the unit.

The unit and its individual shut-off valve m ust be disconnected from the gassupply piping system during any pressure testing of the gas system at testpressures in excess of 1/2 PSIG. The unit must be isolated from the gas supplypiping system by clos ing its individual manual shut-off valve during anypressure testing of the gas supply system at test pressures equal to or less than1/2 PSIG.

W ARNING! A pipe thread com pound resistant to the action of liquefiedpetroleum (LP) and natural gas m ust be used on all pipe joints.

All gas piping should be tested with a soap and water solution to assure gas-tightconnections.

W ARNING! Do not use an open flam e to check for leaks!

MAKING ELECTRICAL CONNECTIONS(208 - 230 Volts)

If local codes perm it, the service cord as supplied with the unit m ay be used. Theservice cord is added at the factory for testing during production. If local codesdo not perm it the use of a service cord, it must be rem oved and the electricalconnections made in the junction box.

A ll external wiring m ust com ply with local codes or national electrical codes.

It is recom m ended that the wiring be on a separate perm anent line electrica lcircuit. The electrical circuit must be protected using dual 15 am p fuse or HACRtype circuit breaker.

In the U.S.A., the unit when installed, m ust be electrically grounded inaccordance with local codes or, in the absence of local codes, w ith the latestedition of National Electrical Code ANSI/NFPA No. 70. Proper operation of thisunit is dependent on adequate earth ground. If the installation is m ade using gaspiping of any m aterial other than m etal pipe, then adequate steps must be takento assure adequate earth ground.

In Canada, the unit m ust be electrically connected and grounded in accordancewith local codes or in the absence of local codes w ith the current CSA C22.1Canadian Electrical Code.

24 VAC EM ERGENCY POW ER CONNECTION (COM PRESSOR LOCK-OUT)

Two 1/4" m ale term inals labeled "PW R DOW N" are available on the m oduleboard. If 24 VAC is applied to these term inals, the compressor and condensorfan operation are disabled. During a call for cooling, the indoor blower will runand the "SERVICE SYSTEM" light will be on.

1. Rem ove the display panel (save the 5 screws for re-use (See Figure 13).

2. Route wiring from an external 24 VAC source through the bushing in the baseof the unit.

3. Term inate two wires with 1/4" fem ale pre-insulated term inals.

4. Connect wires to the "PW R DOW N" term inals on the m odule board (Seewiring diagram ).

5. Replace the display panel.

OPERATING INSTRUCTIONSA. HEAT MODE

Initial Lighting Instructions (See Figure 11)

NOTE: During initia l firing of this furnace, a burn-off of excess paint and oilsrem aining from manufacturing process m ay cause “sm oking” for 5 - 10 m inutes.

NOTE: If your unit has the optional air discharge package installed, werecom m end the room air blower be operated on high (Select high fan speed).

1. Open the manual shut-off valve. The valve is fully open when the handle islevel or parallel to the gas line. Never attem pt to operate unit w ith m anual valvepartially closed.

2. Depress "System " key pad until heat lam p is illum inated.

3. Depress "Fan" key pad until desired speed lam p is illum inated.

4. Set therm ostat to desired setting by depressing temperature indicating arrowsuntil desired tem perature is displayed.

5. If the therm ostat circuit is closed at the setting chosen in step 4, the ignitionsequence begins.

6. After ignition, the operation of the unit will be controlled autom atically by thetherm ostat.

To Shut Down for an Extended Period of Tim e

1. Depress "System " key pad until stand by lam p is illum inated.

2. C lose manual shut-off valve.

Sequence of Norm al Operation - Heat Mode

1. W hen heat is required, the therm ostat closes and energizes the combustionair m otor.

2. As the blower reaches approxim ately 90% of the norm al RPM, the pressurecreated by the com bustion air m otor causes the diaphragm in the pressure switchto move, closing the contacts. This completes the electrical circuit to the input ofthe m odule board and a 10 second warm -up period for the glo-bar is established.During the warm up period, the glo-bar com es on for 7 seconds, then the valveopens. The g lo-bar rem ains on another 3 seconds after the valve opens andthen goes off. W hen the valve opens, it will rem ain open for 6 seconds. Gas willflow to the burner and be ignited by the glo-bar.

3. If the m ain burner flam e is sensed, the burner will rem ain on until thetherm ostat is satisfied. If the flam e is not sensed, the gas valve closes and theignition sequence autom atica lly repeated two (2) tim es. If the burner does notlight during this trial for ignition period, the unit will lock-out for one (1) hour andthen re-set autom atically.

NOTE: If lock-out should occur, the unit can be re-set m anually by breaking thepower to the unit. W hen power is restored, the ignition procedures can berepeated. Should repeated lock-out occur, shut unit down and contact your gasservice agency.

4. After proof of ignition (burner lights and flam e properly sensed) a circuit iscompleted to the room air blower and the blower com es on.

5. W hen the therm ostat is satisfied, the valve closes. The com bustion air m otorwill rem ain on for a 20 second purge cycle, then goes off. The room air blowerwill continue to operate for approxim ately 90 seconds at which tim e the circuit isopened and the room air blower goes off.

NOTE: If your unit is controlled by a wall therm ostat, the ignition sequence is thesame as with built-in therm ostat; however, the tem perature setting and systemfunctions are selected at the wall therm ostat. The "Fan" speed is controlled in thesam e manner as with built-in therm ostat.

B. COOLING MODE

Norm al Operation (See Figure 11)

1. Depress "System " key pad until cool lam p is illum inated.

2. Depress "Fan" key pad until desired speed lam p is illum inated.

3. Set therm ostat to desired setting by depressing temperature indicating arrowsuntil desired tem perature is displayed.

4. If the therm ostat circuit is closed at the setting chosen in Step 3, the coolingcycle begins. NOTE: On initial start-up, the compressor will not be energized forfive (5) m inutes even though the system functions have been properly selected.

W henever the outside tem perature is below 65° and the hum idity is high, frostcould form on the evaporator coil during extended cooling operation. To elim inatefrost form ation, a de-ice switch in the com pressor circuit will sense a frostcondition and open the com pressor circuit. Upon tem perature rise, the switch willclose and the com pressor will again com e on provided the therm ostat is stillcalling for cooling.

NOTE: This unit has a built-in 5 m inute delay between compressor cycles. Anytim e the com pressor cycle is interrupted either m anually, through therm ostat, apower interruption, etc., the com pressor will not restart for 5 m inutes.

C. OPERATING TIPS - HEAT MODE OR COOLING MODE

1. At tim es it may be desirable to reduce the operating sound level. This ispossible by selecting “Low Cool” position. At this setting, the cooling capacity isnot reduced - only the blower speed and air movem ent is reduced.

2. Circulation of room air with no heat or cooling m ay be obtained if desired. Forfan only operation, depress "System " key pad until fan only lam p is illum inated.Depress "Fan" key pad until desired speed lam p is illum intaed.

UNIT CONTROLS AND THEIR FUNCTION

Lim it Switch - The purpose of the lim it control is to turn off the gas to the mainburner if, for any reason, the heating section of the unit becom es hotter than thatwhich is safe. Cycling on lim it does not always indicate a defective lim it switch.If the circulating air is blocked or only partially so, the lim it control will functionand cause the m ain burner to go off. Cycling on lim it is not always undesirable -if it happens only occasionally. This is a good indication of safe operation and willm ost like ly happen on a warm day. If cycling happens too often or for anextended period, the circulating air system should be thoroughly cleaned. (See“Maintenance and Cleaning.”)

If for any reason, the lim it switch is found to be defective, it must be replaced.There is no recom m ended m ethod of repairing it. Because of the im portance ofthe lim it switch, for safety reasons, never shunt the lim it switch - even for onlytem porary operation.

Pressure Switch - The purpose of the pressure switch is to sense the airpressure generated by the com bustion air blower. W hen the pressure isadequate to support com bustion, the contacts in the switch close. This completesthe circuit to the input of the module board and the ignition sequence begins. Iffor som e reason the pressure is not sufficient to support com bustion, the switchwill not operate. Reasons for insufficient pressure: 1) slow com bustion air motor2) restriction in intake and 3) loose pressure switch tube or a blockage in thepressure switch tubing.

Fresh Air Vent - The purpose of the fresh air vent is to prov ide a m eans ofintroducing outside air into the living. The control rod is located in the lower leftfront corner of the unit. To gain access to the control rod, the cabinet front mustbe pivoted forward. (See Figure 13).

NOTE: Operating the unit with the vent open could reduce efficiency of the unitin both heat and cooling m odes.

Overload Protection - These units are equipped w ith an electrical safetyoverload which stops the com pressor in the event of electrical overload. Ifrepeated overload cycling occurs, call your dealer or a local repair agencyequipped to service air conditioning equipm ent.

REMOVING UNIT FOR SERVICE

1. Shut off gas supply to unit.

2. Break electrical circuit to unit at fuse box if wired perm anently. D isconnectwiring in junction box on unit. If service cord is used, unplug from wall receptacle.

3. Disconnect inlet gas line to unit.

4. Disconnect therm ostat wiring at term inal block on module board, if unit iswired for rem ote therm ostat.

5. Pull unit from wall case.

6. To reinstall, reverse above procedure.

7. Check gas connections for leaks using a soap and water solution. Do not usean open flam e to check for leaks. Correct any gas leaks imm ediately.

W ARNING! If the user of this appliance fails to m aintain it in the conditionin which it was shipped from the factory or if the appliance is not usedsolely for its intended purpose or if appliance is not m aintained inaccordance with the instructions in this m anual, then the risk of a fireand/or the production of carbon m onoxide exists which can causepersonal injury, property damage or loss of life.

IMPORTANT: Always verify proper operation after servicing.

W ARNING! Always disconnect electrical supply before cleaning unit orperform ing any m aintenance.

The unit should be inspected by a qualified service person yearly before turningthe unit on heat for the winter. Particular attention should be given to the following:

1. Inspect all gaskets. If any gaskets show signs of leakage or deterioration, theym ust be replaced. Safe operation of the unit depends on all gaskets being tight.

2. Inspect com bustion cham ber and venting to assure that these com ponents arephys ically sound without holes or excessive corrosion. Replace if found to bedefective.

3. Inspect exhaust and intake for restrictions and for adequate sealing of anym ating parts. (See “Minimum Outside Clearances”.)

W ARNING! It is im perative that the products of com bustion be properlyvented to the outside atm osphere and that all com bustion air supplied tothe burner be drawn from the outside atm osphere.

4. Check outside grille to be sure it is clean and free of any obstructions.

5. Check the control com partm ent, burner and circulating air passageways of theunit. These areas must be kept clean. NOTE: More frequent cleaning m ay berequired due to excessive lint from carpeting, bedding m aterial, etc.

6. Check burner for proper operation. A proper flam e will have a blue inner conewith well defined pattern and an orange outer cone with slightly yellow tips. Aflam e that is yellow in appearance with an erratic flam e pattern indicates arestriction in the air supply. Shut the unit down and have the burner and airpassage ways checked and cleaned as needed. The surface of the burner andeach burner port should be cleaned with a steel wire brush and blown clean usingcompressed air. (See Figure 14 for illustration of a correct and incorrect burnerflam e.)

7. Check all gas connections and gas controls (electrical valves, manual shut-offvalves, regulators, etc.) for leaks.

8. This inspection should include a com plete operational check of the unitincluding all elec trical and mechanical com ponents. NOTE: If cabinet front wasrem oved in order to inspect the unit and controls, it must be reinstalled prior tooperating the unit.

You as the owner/user should inspect the unit periodically during theheating season. Particular attention should be given to the following:

A. Periodically observe the main burner flam e to assure it is burning with a hardblue flam e with well-defined burner ports. (See Figure 14.) If flam e appears yellowor burner has a lazy flame, shut furnace down and contact a qualified serviceperson.

B. Periodically inspect the vent for obstructions or presence of soot. Soot isform ed whenever com bustion is incom plete. This is your visual warning that thefurnace is operating in an unsafe manner. If soot is present, im m ediately shutfurnace down and contact your dealer or a qualified service person.

C. Circulating air through the front grille must not be blocked. Keep filter clean toassure adequate air flow.

The rem ovable, washable type filter should be cleaned or replaced several tim esduring the year. This will depend upon the usage and location of the unit. A dirtyfilter will reduce the air flow and the efficiency of the unit. Filter m ay be washed ina soapy solution and rinsed in clean water. Let the filter dry before reinstalling iton the unit.

The filter is located behind the cabinet front. The cabinet front pivots forward foreasy access to the filter. To rem ove the filter, rotate retaining arm free of filter, andlift filter up.

Listed below are several safety related item s that you should follow during theheating season to assure continued safe operation of the furnace.

1. Never operate the unit if you smell gas. Do not assum e that the smell of gasis norm al. Any tim e you detect the odor of gas, it is to be considered lifethreatening and corrected imm ediately. (See safety notice on front cover of thism anual.)

2. Im m ediately shut unit down and call a service agency if unit cycles erraticallyor delays on ignition.

W ARNING! Should overheating occur, or the gas supply fail to shut off,shut off the manual gas valve to the appliance before shutting off theelectrical supply.

3. Do not restrict the flow of com bustion air or the warm air circulation to the unit.To do so could cause personal injury and/or death.

W ARNING! Do not install screens over the vent for any reason. Screenswill becom e restricted and cause unsafe furnace operation.

4. Keep unit clean. More frequent cleaning m ay be required due to excessive lintfrom carpeting, bedding m aterial, etc. It is im perative that control com partm ents,burners and circulating air passageways of the appliance be kept clean.

5. Keep the furnace area clear of any com bustible materials, gasoline or otherflam m able vapor and liquids.

6. Do not use this appliance if any part has been subm erged under water.Im m ediately call a qualified service technician to inspect the appliance and toreplace any part of the control system and any gas control that has beensubm erged under water.
