Constructing the Fireplace Chase

A chase is a vertical box-like structure built to enclose thegas fireplace and/or its vent system. Vertical vents that runon the outside of a building may be, but are not required tobe, installed inside a chase.

CAUTION: TREATMENT OF FIRESTOP SPACERS ANDCONSTRUCTION OF THE CHASE MAY VARY WITH THETYPE OF BUILDING. THESE INSTRUCTIONS ARE NOTSUBSTITUTES FOR THE REQUIREMENTS OF LOCALBUILDING CODES. THEREFORE, YOUR LOCAL BUILD-ING CODES MUST BE CHECKED TO DETERMINE THEREQUIREMENTS FOR THESE STEPS.

Factory-built fireplace chases should be constructed in themanner of all outside walls of the home to prevent cold airdrafting problems. The chase should not break the outsidebuilding envelope in any manner.

This means that the walls, ceiling, base plate and cantileverfloor of the chase should be insulated. Vapor and air infiltra-tion barriers should be installed in the chase as per regionalcodes for the rest of the home. Additionally, in regions wherecold air infiltration may be an issue, the inside surfacesmay be sheetrocked and taped for maximum air tightness.

To further prevent drafts, the firestops should be caulkedwith high temperature caulk to seal gaps. Gas line holesand other openings should be caulked with high temp caulkor stuffed with unfaced insulation. If the appliance is beinginstalled on a cement slab, a layer of plywood may be placedunderneath to prevent conducting cold up into the room.

THE CHASE SHOULD BE CONSTRUCTED SO THAT ALLCLEARANCES TO THE FIREPLACE ARE MAINTAINEDAS SPECIFIED WITHIN THIS INSTALLERS GUIDE.

Clearance RequirementsThe top, back, and sides of the fireplace are defined bystand-offs. The minimum clearance to a perpendicular wallextending past the face of the fireplace is one inch (25mm).The metal ends of the fireplace may NOT be recessed intocombustible construction.

The distance from the unit to combustible constructionis to be measured from the unit outer wrap surface tothe combustible construction, NOT from the screw headsthat secure the unit together.


Figure 3.2 Framing Dimensions

Step 2. Framing the FireplaceFireplace framing can be built before or after the fireplace isset in place. Framing should be positioned to accommo-date wall coverings and fireplace facing material. The dia-gram below shows framing reference dimensions.CAUTION: MEASURE FIREPLACE DIMENSIONS ANDVERIFY FRAMING METHODS AND WALL COVERINGDETAILS BEFORE FRAMING.

NOTE: A 1” clearance (B-Vent) or 1-1/2” clearance(PV-FLEX) must be maintained between the top ofthe pipe in a horizontal configuration and anycombustible materials. Otherwise, 1” clearanceshould be maintained between the pipe and anycombustible materials.

Framing should be constructedof 2 X 4 lumber or heavier.

Figure 3.3

Draft is the pressure difference needed to vent fireplacessuccessfully. Considerations for successful draft include:• Preventing negative pressure• Location of fireplace and chimney

Negative pressure results from the imbalance of air avail-able for the fireplace to operate properly. Causes for thisimbalance include:

• Exhaust fans (kitchen, bath, etc.)

• Range hoods

• Combustion air requirements for furnaces, water heat-ers and other combustion appliances

• Clothes dryers

• Location of return-air to furnace or air conditioning

• Imbalances of the HVAC air handling system

• Upper level air leaks (recessed lighting, attic hatch open-ing, duct leaks)

To minimize the effects of negative air pressure, the follow-ing must be considered:

• Install the fresh air kit. Install the intake on the side ofthe house towards prevailing winds during the heatingseason.

• Ensure adequate outdoor air is supplied for combustionappliances and exhaust equipment.

• Ensure furnace and air conditioning return vents are notlocated in the immediate vicinity of the fireplace.

• Avoid installing the fireplace near doors, walkways orsmall isolated spaces.

• Recessed lighting should be of “sealed can” design; at-tic hatches weather stripped or sealed; and attic mount-ed ductwork and air handler joints and seams taped orsealed.

• Basement installations should be avoided due to stackeffect. Stack effect creates negative pressure in lowerlevels. Hearth & Home Technologies recommends theuse of direct vent fireplaces in basements.

Location of the fireplace and chimney will affect performance.As shown in Figure 3.3, the chimney should:

• Be installed through the warm space enclosed by thebuilding envelope. This helps to produce more draft, es-pecially during lighting and die-down of the fire.

• Penetrate the highest part of the roof. This minimizesthe effects of wind turbulence.

• Be located away from trees, adjacent structures, un-even roof lines and other obstructions.

Offsets can restrict draft so their use should be minimized.Consider the fireplace location relative to floor and ceilingand attic joists.

Asphyxiation Risk.• Negative pressure can cause spillage of

combustion fumes and soot.• Fireplace needs to draft properly for safety.

WARNING


This unit is equipped to accept outside air. It is recom-mended that an AK-TV air kit be used with this appli-ance. By using outside make-up air, the amount of roomair used for combustion will be reduced. However, in a neg-ative pressure condition the outside air kit MUST be in-stalled to obtain proper performance and to help preventspillage of combustion gases.

A 4-inch side collar/damper (found in AK-TV Kit) must beinstalled on the fireplace by attaching the side collar to theouter wrap of the fireplace at the right-hand rear corner usingsheetmetal screws. Attach damper handle (extended handlefound in manual bag) to the damper door prior to attachingdoor to outer wrap. Then lift the handle into the notch underthe fireplace. See Figure 3.5. Attach one end of a 4-inchflexible air duct (not provided in the AK-TV Kit) to the sidecollar and the other end of the duct to the make-up airtermination cap. Use plastic tie straps to secure the endsof the flex duct to each collar.

Air Damper

Before lighting the burner, open the damper. Close thedamper when the burner is off.

Step 4. Installing the Vent System

A. Vent System ApprovalsModel GATEWAY is approved to use Duravent 4-inch(102mm) diameter B-type vent for installations that terminatevertically. The PV-Flex Series vent pipe is approved for usein installations that terminate horizontally. This pipe is testedand listed as an approved component of the fireplace.

This model may also use single wall rigid or flexible gasvent IF and ONLY IF the vent system is installed withinnon-combustible construction such as a masonry chimney.The same diameter noted above for B-type vent must beused for single-wall vent (see Figure 3.6).

For B-type vent the clearance to combustibles is 1-inch.Follow vent manufacturers REQUIRED clearances. For PV-Flex the clearances are 1-1/2” top and 1” sides and bottomwhen venting horizontally. For PV-Flex the clearances are1” all sides when passing vertically through combustiblematerials.

High temperature silicone sealant is required at all pipe joints.

NOTE: Due to the positive pressure within the Gatewayventing system, when using PV-FLEX use a 1/2” beadof silicone caulk on ALL pipe ends and connectorsthroughout the vent run to ensure a completely sealedsystem.

Vent pipes must be installed within the conditioned houseenvelope in order to avoid flue gas condensation. Verticaltermination through an unconditioned attic space ispermissible.

The flame and ember appearance may vary based on thetype of fuel burned and the venting configuration used.

B. System ComponentsConsult Local Building Code Officials and Codes for propervent system installations.

Plan and install the vent system using the parameters shownin this vent system configuration chart.

! WARNING: THIS GAS FIREPLACE MUST NEV-ER BE VENTED BY CONNECTING TO A CHIM-NEY FLUE SERVING A SEPARATE SOLID FUELBURNING APPLIANCE.

The following figures are examples of approved venting con-ditions. Venting downward (3’ maximum) is approved, toallow venting below the floor. However, only one downwardsection is allowed for up to, but not exceeding 3’ maximum.

NOTE: It is always better to first attach a straight section ofvent to the unit before attaching an elbow. Avoid using el-bows in the vent system if possible.

Continue to add vent components, until the vent run is com-pleted.

Using the four screws provided in the manual bag, attachthe flue outlet collar. Connect a vent component to the flueoutlet collar (see Figure 3.6).

For Vertical Terminations - To locate the vent andinstall the vent sections:• Locate and mark the vent centerpoint on the underside

of the roof, and drive a nail through the centerpoint.

• Make the outline of the roof hole around the centerpointnail.

• The size of the roof hole framing dimensions depend on thepitch of the roof. There MUST BE a 1-inch (25.4mm) clear-ance from the vertical vent pipe to combustible materials.

• Mark the roof hole accordingly.

• Cover the opening of the installed vent pipes.

• Cut and frame the roof hole.

• Use framing lumber the same size as the roof raftersand install the frame securely. Flashing anchored to theframe must withstand heavy winds.

• Continue to install concentric vent sections up throughthe roof hole (for inside vent installations) or up past theroof line until you reach the appropriate distance abovethe roof (for outside terminations).

WARNING: MAJOR U.S. BUILDING CODESSPECIFY MINIMUM CHIMNEY AND/OR

VENT HEIGHT ABOVE THE ROOF TOP. THESE MIN-IMUM HEIGHTS ARE NECESSARY IN THE INTER-EST OF SAFETY. SEE THE FOLLOWING DIAGRAMFOR MINIMUM HEIGHTS, PROVIDED THE TERMI-NATION CAP IS AT LEAST TWO (2) FEET FROM AVERTICAL WALL AND 2-FEET BELOW A HORIZON-TAL OVERHANG.

NOTE: This also pertains to vertical vent systems in-stalled on the outside of the building.

!

To seal the roof hole, and to divert rain and snow from thevent system:

• Attach a flashing to the roof using nails, and use a non-hardening mastic around the edges of the flashing basewhere it meets the roof.

• Attach a storm collar over the flashing joint to form awater-tight seal. Place non-hardening mastic around thejoint, between the storm collar and the vertical pipe.

• Slide the termination cap over the end of the vent pipeand rotate the pipe clockwise 1/4 turn.

Step 5. Positioning, Leveling, and Securing the FireplaceThe diagram below shows how to properly position, level,and secure the fireplace.

Figure 3.24Proper Positioning, Leveling,and Securing of a Fireplace

• Place the fireplace into position (see Figure 3.24).• Level the fireplace from side to side and from front to

back.• Shim the fireplace with non-combustible material, such

Step 7. The Gas Supply LineNOTE: Have the gas supply line installed in accordancewith local building codes by a qualified installerapproved and/or licensed as required by the locality.(In the Commonwealth of Massachusetts installationmust be performed by a licensed plumber or gasfitter).NOTE: Before the first firing of the fireplace, the gassupply line should be purged of any trapped air.NOTE: Consult local building codes to properly sizethe gas supply line leading to the 1/2 inch (13mm)hook-up at the unit.This gas fireplace is designed to accept a 1/2 inch (13mm)gas supply line. To install the gas supply line:• A listed (and Commonwealth of Massachusetts approved)

1/2 inch (13mm) tee-handle manual shut-off valve and alisted flexible gas connector are connected to the 1/2inch (13mm) inlet of the control valve. NOTE: If substi-tuting for these components, please consult local codesfor compliance.

• Locate the gas line access hole in the outer casing ofthe fireplace.

• The gap between the supply piping and gas access holecan be plugged with non-combustible insulation to pre-vent cold air infiltration.

• Open the fireplace lower grille, insert the gas supply linethrough the gas line hole, and connect it to the shut-offvalve.

• When attaching the pipe, support the control so that thelines are not bent or torn.

• After the gas line installation is complete, all connec-tions must be tightened and checked for leaks with acommercially-available, non-corrosive leak check solu-tion. Be sure to rinse off all leak check solution followingtesting.

Step 12. Before Lighting the FireplaceBefore lighting the fireplace, be sure to do the following:Remove all paperwork from underneath the fireplace.Review safety warnings and cautions• Read the Safety and Warning Information section at

the beginning of this Installers Guide.Double-check for gas leaks• Before lighting the fireplace, double-check the unit for

possible gas leaks.Double-check vent terminations and front grilles for

obstructions.• Before lighting the fireplace, double-check the unit for

possible obstructions that could be blocking the vent ter-minations or the front grilles.

Double-check for faulty components• Any component that is found to be faulty MUST BE re-

placed with an approved component. Tampering with thefireplace components is DANGEROUS and voids all war-ranties.

• Confirm that 3V transformer is plugged into the junctionbox as shown in Figure 3.27.

• Ensure vacuum hose (telfon tube) is firmly connected atthe vacuum hose connection point on both the blowerand the vacuum switch (see Figure 3.27).

!

A small amount of air will be in the gas supply lines. Whenfirst lighting the fireplace, it will take a few minutes for thelines to purge themselves of this air. Once the purging iscomplete, the fireplace will light and will operate normally.Subsequent lightings of the fireplace will not require thispurging of air from the gas supply lines, unless the gasvalve has been turned to the OFF position, in whichcase the air would have to be purged.NOTE: The fireplace should be run 3 to 4 hours on theinitial start-up. Turn it off and let it cool completely. Removeand clean the glass. Replace the glass and run the fireplacefor an additional 8 hours. This will help to cure the productsused in the paint and logs.

GLASS SPECIFICATIONS:

MODEL GLASS TYPEGATEWAY TEMPERED

Heat & Glo fireplaces manufactured with tempered glassmay be installed in hazardous locations such as bathtubenclosures as defined by the CPSC. The tempered glasshas been tested and certified to the requirements of ANSIZ97.1-1984 and CPSC 16 CFR 1202. (Safety Glazing Certi-fication Council SGCC # 1595 and 1597. Architectural Test-ing, Inc. Reports 02-31919.01 and 02-31917.01.)

This statement is in compliance with CPSC 16 CFR Sec-tion 1201.5 “Certification and labeling requirements” whichrefers to 15 USC 2063 stating “…Such certificate shall ac-company the product or shall otherwise be furnished to anydistributor or retailer to whom the product is delivered.”

Some local building codes require the use of tempered glasswith permanent marking in such locations. Glass meetingthis requirement is available from the factory. Please con-tact your dealer or distributor to order.

Lava RockIf desired, pour the Lava Rock from the plastic bag aroundthe outside of the log grate. DO NOT place any Lava Rockon top of the burner.

During this break-in period it is recommended that somewindows in the house be opened for air circulation. This willhelp avoid setting off smoke detectors, and help eliminateany odors associated with the fireplace’s initial burning.

Step 13. Lighting the FireplaceYou’ve reviewed all safety warnings, you’ve checked thefireplace for gas leaks, you know the vent system isunobstructed, and you’ve checked for faulty components.Now you’re ready to light the fireplace.
