Packaged Hot Water SystemsAce Series packaged hot water systems are engineered to meet continuous load demands. Continuous output is the rated output of the heater. Peak load output is the rated output of the heater plus drawing upon the storage tank reserve capacity. Shorter peak load capacities, at higher output rates and longer peak loads at lower rates, can be handled by the Ace Package Hot Water Systems. In addition to peak load capacities the Ace Systems will handle overloads with a proportional decrease in output water temperature; for example, a 20 percent overload would result in a 20 percent decrease in the rated 100ºF rise temperature or an 80ºF rise temperature, etc. Apartments and motels experience two and three hour peak loads in the morning and evenings; school and dormitory peak loads occur during shower hours; restaurant and hotels peak load are during meal and clean-up times; etc. Peak load requirements are normally the most significant selection criteria.

The Ace Series packaged hot water system is an automatic circulating type heater with a storage tank. The cold make up water enters the storage tank and mixes with hot water in the tank to raise the temperature of the water entering the heater to eliminate condensation in the heater. Return loop warm water is brought in at the suction side of the circulating pump to boost the blended water temperature entering the heater to 140ºF and reduces the possibility of condensation. If the peak load fluctuations are not too large, a small storage tank may be used. Or the volume of water in the building hot water piping may be large enough to provide the blending and recirculation requirement.

A larger storage tank should be used when very high short duration peak load conditions occur.

Automatic recirculation and blending are required to obtain the desired “gallons per hour output” at the needed temperature “rise.” The illustration shows the heater/boilers recirculating water and the blending with both make up and return water.

Refer to individual package product section for the recovery rate in the gallons per hour for a range of temperature rise for each heater/boiler model size.

By setting the operating aquastat for the desired output water temperature the heater/boiler will stay on until the temperature setting is reached. The heater/boiler standard output rating is 40ºF to 140ºF temperature “rise.” The equivalent water heating output for each of the temperature rises can be provided by the heater/boiler based upon the make up water and/or return water input temperature and the output aquastat temperature setting.

* Allow additional 6 inches between vertical tank and heater for piping and pumps and 6" above vertical tank for piping. Allow additional 12" in front of package units for piping. Prices are for vertical mounted tanks only. Add approximately from 8" to 12" to increase overall height.

Sizing recommendations are for maximum demands experienced under standard conditions - normal installation. Sizing is based upon 3 GPM showers (one per unit), 40ºF inlet to 140ºF outlet water, a hot water return line (3 to 5 GPM flow), no dishwashers and no automatic washers.

The following correction factors should be applied to the number of units, occupants, people, or beds to adjust the requirement before selecting per the above table.

For Multiplier 2 bath units 1.3 5 GPM shower heads 1.4 up to 75 units 1.3 for 100 or more units 50ºF Inlet Water 0.9 60ºF Inlet Water 0.8 Altitude 1.04 for each 1000 ft. above sea level

Dishwasher - Add approximately 10 to 12 GPH heater recovery for each dishwasher.

Automatic washer - Add 40 to 50 GPH heater recovery for each standard size washer. Note: Some standard make washers take up to 60 GPH.

For 180ºF sanitizing water for dishwasher or laundry using a cement lined tank, increase GPH addition by 1.3 multiplier and provide for mixing valve.

Heater recovery rated @ 80% efficiency base on manufacturing lab. test. Ace Series heater working pressure 160#

Altitude: Derate heater output by 4% for each 1000 ft. above sea level.

Operating Controls• Digital panel• Remote SetPoint panel• Local monitoring panel• Building Automation panel• Ajax Communication Gateway

The Mini-Pack™ temperature control system keeps the heated water within four degrees of the selected temperature. This close control is accomplished by placing the temperature control element directly in the constant fl ow path of the water leaving the heating surface making so-called “anticipator” devices unnecessary. After the water passes over the control element it enters a tempering chamber between the heating surface and the water outlet.

Another essential part of the temperature control system is the integral circulator. This small pump (1/6 HP) constantly recirculates a portion of the heated water to the cold water inlet making “the total volume of the heater” a tempering chamber. Also eliminates any overheated water pockets caused by control valve lag when hot water demand is suddenly reduced. The pump can also be used to provide recirculation of the water from the fi xtures through a tee fi tting that is provided with the package. Where the hot water return system requires greater recirculation the integral pump size can be pre-selected to provide the duty.

The Mini-Pack™ features total rust free construction with austenitic stainless steel and copper for all domestic water contact surfaces, providing high quality, low maintenance and an extremely cost-effective domestic water heating package. Non-metallic PTFE baffl es are used to prevent tube damage.

The vertical Mini-Pack™ semi-instantaneous heater saves fl oor space, is simple to install and very easy to service and maintain. The vertical unit also provides complete drainage of condensate. Universal mounting brackets allow the Mini-Pack™ to be mounted in the horizontal position.

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.

NOTES

Series


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.

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.


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.
