FOR YOUR SAFETY
Do not store or use gasoline or other flammable vapors and liquids or other combustible materi-
als in the vicinity of this or any other appliance. To do so may result in an explosion or fire.
WARNING: Improper installation, adjustment, alteration, service or maintenance can cause prop-
erty damage, personal injury or los

DANGER: Make sure the gas on which the boiler will operate is the same type as that specified on the boiler model and rating plate. WARNING: Should overheating occur or the gas supply valve fail to shut, do not turn off or disconnect the electrical supply to the boiler. Instead, shut off the gas supply at a location external to the appliance. WARNING: Do not use this boiler if any part has been under water. Immediately call a qualified service technician to inspect the boiler and to replace any

MODEL IDENTIFICATION The model identification number and boiler serial number are found on the boiler data plate located on the left inside jacket of the boiler. The model number will have the form H4 0500A ADB or similar depending on the boiler size and configuration. The first character of the model number identifies application (H = Hydronic Heating System, W = Hot Water Supply System, P = Pool Application). The second character identifies the firing mode (4 = On-Off firing). The next four pl

SECTION C: COMBUSTION AND VENTILATION AIR COMBUSTION AND VENTILATION AIR (Indoor Units) The boiler must be supplied with sufficient quantities of non-contaminated air to support proper combustion and equipment ventilation. Combustion air can be supplied via conventional venting, where combustion air is drawn from the area immedi- ately surrounding the boiler, or via direct vent, where combustion air is drawn directly from outside. All installations must comply with the requirements of NFGC for

All Air from Outdoors. If all combustion air is drawn from the air outside the building (the mechanical equipment room directly communicates with the outdoors), either of the following two methods can be used: Method 1: 1. The mechanical equipment room must be provided with two permanent openings, one commencing within (twelve) 12 inches of the top, and one commencing within twelve (12) inches of the bottom of the room. 2. The openings must communicate directly, or by ducts, with the outdoors. 3

SECTION D: WATER PIPING - GENERAL The boiler should be located so that any water leaks will not cause damage to the adjacent area or structures. All units should be plumbed in accordance with the appropriate diagram from Section E, F or G or per a suitable engineered piping arrangement. CAUTION: This boiler requires forced water circulation when the burner is operating. See Table D-1 for minimum and maximum flow rates and water pump selection. The pump must be interlocked with the boiler to p

SECTION E: HYDRONIC HEATING PIPING PUMP SELECTION In order to insure proper performance of your boiler system, you must install a properly sized pump. Raypak recommends using a 20°F Delta T as design Delta T. (Delta T is the temperature difference between the inlet and outlet water when the boiler is firing at full rate). If a Delta T larger than 20°F is necessary, the bypass must be installed and adjusted to insure proper hydraulics through the boiler while still allowing minimum flow to satisf

PRESSURE DROP IN FEET OF HEAD FEEDWATER REGULATOR Raypak recommends that a feedwater regulator be installed and set at 12 PSIG minimum pressure at the highest point of system. Install a check valve or back flow device upstream of the regulator, with a manual shut off valve as required by local codes. PIPING - HEATING BOILERS All high points should be vented. Purge valves and a bypass valve should be installed. A boiler installed above radiation level must be provided with a low water cutoff devi

SECTION F: DOMESTIC HOT WATER PIPING When designing the water piping system for domestic water applications, water hardness should be considered. Table D- 1 indicates the suggested flow rates for soft, medium and hard water. Hardness is specified as grains per gallon.

SECTION G: POOL HEATING CAUTION: Power to the heater should be interlocked with the main system pump to make sure the heater does not fire without the main system pump in operation. Improper flow control can damage the heater. Uncontrolled flow (too high) or restricted flow (too low) can seriously affect heater operation. Follow these instructions to make sure your heater is properly installed. The ADB unit is equipped with an external pump and bypass arrangement that blends outlet water with

POOL AND SPA WATER CHEMISTRY NOTE: Chemical imbalance can cause severe damage to your heater and associated equipment. Maintain your water pH between 7.4 and 7.8 and total alkalinity between 100 and 150 p.p.m. If the mineral content and dissolved solids in the water become too high, scale forms inside the heat exchanger tubes, reducing heater efficiency and also damaging the heater (max TDS at 3000 p.p.m.). If the pH drops below 7.2, the heater will be severely damaged. NOTE: Heat exchanger d
