VERTICALSTEAM-TO-WATERPILOT-OPERATED
HORIZONTALSTEAM-TO-WATERPILOT-OPERATED
Packaging items may extend beyond vessel dimensions. For vertical packaging, add approximately 15" to tank height for overall height and 24" diameter for depth. For horizontal packaging, size is tank diameter and overall length add approximately 15" (for base) to obtain height and 24" to overall length to allow for coil and controls. Output is based upon clean copper tube condition. Ajax recommends 25% to 75% oversizing depending upon hardness of water. Tubes should be inspected frequently and descaled as required.1Ace Temp Control System Automatic Rapid Temperature Response. The Ace Temp Control System will accurately vary the fl ow of steam of the heating coil in proportion to the variation in fl ow and temperature of the domestic water demands. Ace Temp Control System provides rapid response by locating control bulb in recirculating line thereby eliminating delays due to lengthy bleed lines. Ace Temp Control System senses blended water temperature for instant smooth opening and closing of steam control valve, also eliminates excessive cycling of steam valve that can occur when short bursts of cold water are fl ushed over an immersed sensor bulb.

Double-Wall Tube BundlesMeets Uniform Plumbing Code requirements for heating potable water. Prevents cross-contamination. Tested and certifi ed by the City of Los Angeles Testing Laboratory.
• Easy Inspections and low maintenance• Fully visible, 360º vented leak detection between tubesheets.• Bolting and gaskets for potable water and heating medium are completely independent.• Individual tube access for easy maintenance.• Optional: Tubesheet contacting potable water is solid 304 stainless steel.• Used to upgrade present single-wall tube bundles.• Available in storage semi-instantaneous water heaters and exchangers with copper or
cupro-nickel tubes and carbon steel or stainless steel tube sheets (Up to 400 PSIG with cupro-nickel tubes)
Double-Wall Protection PerformanceTube failure can be caused by corrosion, erosion, and vibration, and can result in the contamination of the domestic water system to be contaminated by a heating medium such as steam, hydronic water, glycol solution, etc. There is no practical way to have the heating medium sterile or free from harmful treatment compounds or corrosion by-products. A low pressure heating medium circuit does not ensure contamination protection of indirect, single-wall water heaters. Whether they are shell and tube, shell and coil, plate and frame, or any other type, all consist of relatively thin wall heat transfer surface separating the heating medium from the domestic water system. Therefore, the potential for cross contamination is real and in some instances contamination has occured. Several states and cities are now insisting on double-wall vented construction in all direct type domestic water heaters. Plumbing codes have also been re-written to include double-wall protection. Ajax Boiler has developed the most practical, “state-of-the-art” double tube wall heaters to preclude any possibility of contaminating the domestic water system.
The Ace Series double-wall is the most positive form of double tube wall construction available, with no sacrifi ce in water heater effeciency or performance over a single tube wall heater.
The heat transfer surface is 5/8" O.D. x .042" thick inner wall and 3/4" O.D. x .042" outer wall SB-75 copper tubing. The .042" dimensions are actual net tube wall thicknesses which equal .084" thickness of total wall separation. This is more than twice the thickness of many single wall water heater products. Both inside and outside tube surfaces are smooth (prime) with no fins or surface irregularities to promote scale formation or corrosion attack.
Double-wall tubing has a similar overall heat conductivity as a single wall tube of equivalent wall thickness. The heat transfer capabilities were determined by actual tests conducted at the Ajax Boiler facilities. Each tube has multiple parallel and continuous vent paths.

Condensing will occur during the combustion process when the combustion gases come in contact with cool heating surfaces of boilers and water heaters. Condensation will cause damage to all fi red boilers and water heaters.
The moisture from condensation will cause incomplete combustion which will reduce the combustion effi ciency and cause sooting of the boiler. Sooting will reduce the heat transfer effi ciency and clog the fl ue gas passages disrupting the combustion process. On atmospheric fi red boilers, clogged fl ue passages may cause fl ame roll out from the combustion chamber and a fi re hazard.
Moisture in the fl ue gases from condensation will cause rusting of the boiler tubes and the boiler stack and also damage boiler refractory and insulation.
Condensation can be prevented in properly designed boiler and water heating systems by maintaining inlet water temperatures above the dew point. Dew point, depending upon the atmospheric pressure, temperature and humidity conditions, will normally occur when the water inlet temperature is in the 120ºF to 130ºF range. It is generally accepted therefore, that 140ºF boiler water inlet temperature should be maintained to provide a small operating safety margin. Condensation damage can also be reduced by limiting cold start ups to once or twice a year. Night set back controls and delayed-system three way valves can minimize low temperature fi ring.
For low temperature applications such as water source heat pumps, low temperature heating systems, low temperature water heating application such as used in convalescent home, Ajax Boiler Inc. offer boiler and water heater “return loop blend” (RLB) packages. The RLB packages are furnished with manual valves for systems with relatively constant fl ow and temperature conditions. Failure to maintain 140ºF inlet water temperature will void your boiler warranty.
For a main loop fl ow of 3,520GPH, at a temperature rise of 30ºF, select Model B11G from the table. (Note: Maximum main loop supply temperature is 200ºF.)
For only main loop fl ow and temperature rise conditions, the boiler will heat a fraction of the main loop fl ow. The heated water will then be returned to the main loop where it will mix with unheated water to provide the desired loop temperature. For inlet water temperatures below 140ºF, some of the hot water exiting the boiler must be returned to the boiler water inlet to provide a blended inlet water temperature of 140ºF or higher. This return-blend action is activated by closing the blend valve until the temperature at the boiler inlet reaches 140ºF.
For boiler output higher than 1,200,000BTU/Hr, use multiple units.

The Ajax Boiler Factory limited warranty provides assurance that all products are free from manufactures defects at the time of shipment and meet specifi cations and performance described in the product literature. It is important to understand the difference between a factory warranty and an installed warranty. There are many factors that can occur to the products after they are shipped that the company has no control over and cannot fully verify. These include: 1. Hidden damage during the shipping 2. Handling damage 3. Damage during storage 4. Installation conditions 5. Other unknown variables in the system design, operations, maintenance, pulsation and vibrations.
The installed warranty is the responsibility of the architect, specifying engineer, contractor and or owner who jointly have control over the application, installation, location, operating and maintenance conditions. The AJAX BOILER INC. warranty excludes extended liabilities. Extended liability typically occurs when products are installed without proper drainage, fl ooding containment or when safety devices are not tested and repaired or replaced when needed. Product problems are often caused by the condition of the water, the lack of water treatment and or the improper treatment of the water, insuffi cient combustion air, improper draft conditions, bolts not re-tightened, pipes not fl ushed and cleaned of oil, metal chips, rags, vibration and pulsation etc. These are installation, operating and/or maintenance conditions that are beyond the seller’s responsibility and are not covered by the factory warranty, but may be covered by the installer’s warranty. The factory warranty covering company products is based upon extensive product development and testing. Combustion products under go certifi cation testing and approvals to Underwriters Laboratory standards. Auditing of the production of combustion products is conducted by a nationally recognized testing laboratory. Pressure vessel products are designed and manufactured to American Society of Mechanical Engineering (A.S.M.E.) and National Board (NB) Design standards. Design reviews, factory product manufacturing quality inspections and testing are carried out by a third party National Board authorized inspection agency. AJAX BOILER INC. products have proven themselves in service for over 85 years which indicates that the company products perform exceedingly well when normal installation, operating
and maintenance conditions exist. The following is a review from the terms and conditions of sale. Also included in paragraph two, below, is the AJAX BOILER INC. non-conformance policy.
1. AJAX BOILER INC. warrants its products against defective material and/or workmanship only. The warranty does not apply to operational failures, electrical failures, gasket leaks, and or other malfunctions caused by improper application, installation and or maintenance.2. It is the buyer’s responsibility to inspect and accept the product, when received, as conforming to their purchase order, specifi cations and approved drawings. All claims for non-conformance, errors, shortages, etc. must be made within 10 days after receipt of the shipment.3. AJAX BOILER INC. do not provide a warranty or guarantee, express or implied, in any manner, form, usage of trade, merchant-ability or fi tness which extend beyond the product description and quotation.4. AJAX BOILER INC. liability is limited to the factory repair or replacement of warranty failures, or non-conformance, upon the return of the product to the factory.5. AJAX BOILER INC. is not liable for any direct or consequential damages.6. The AJAX BOILER INC. warranty is based upon section 23161(2) of the uniform commercial code and is printed in the terms and conditions of sale which is referenced in every quotation, on the back of sales order acknowledgements and invoices. It is legally correct and is an industry standard policy.
THERMAL SHOCK In addition to our standard one (1) year warranty against defective parts and workmanship, AJAX BOILER INC. provides the following guarantee with all commercial hot water, forced circulation, space heating boilers: AJAX BOILER INC. guarantees this new boiler pressure vessel for ten (10) years after date of installation from damage due to thermal shock. Thermal shock occurs when cold makeup water, up to 150°F less than the boiler water outlet temperature, is added directly into the boiler while the boiler is operating within the normal temperature range from 140°F to 250°F with a temperature rise from 20°F to 40°F. This guarantee shall cover damage to the boiler tubes, tube headers, and tube sheets when such damage is attributed to unequal expansion, poor circulation and/or other causes quite often described as “thermal shock.” This guarantee does not cover damage or failures that can
