Figure 13. NOTE You “DO NOT” need the plastic bushings. 1. Insert pipe into the inlet/outlet openings of the “Quick-Flange” 2. Slip the rubber gaskets over the pipe, using the supplied 2 in. rubber gasket for 2 in. copper pipe or the 1. in. rubber gasket (not supplied, available from the factory) for the 1. in. copper pipe. 3. Bolt the “Quick-Flange” to the header. Figure 15. FOR 1. & 2 in. COPPER PIPE Gasket Figure 14. * * Pipe Plastic Bushing Gasket/Sleeve P/N 471048 Rev. G 1-22-04 Installation (contd.) 16 GAS CONNECTIONS GAS LINE INSTALLATIONS Before installing the gas line, be sure to check which gas the heater has been designed to burn. This is important because different types of gas require different gas pipe sizes. The rating plate on the heater will indicate which gas the heater is designed to burn. Table 7, shows which size pipe is required for the distance from the gas meter to the heater. The table is for natural gas at a specific gravity of .65 and propane at specific gravity of 1.5. When sizing gas lines, calculate three (3) additional feet of straight pipe for every elbow used. When installing the gas line, avoid getting dirt, grease or other foreign material in the pipe as this may cause damage to the gas valve, which may result in heater failure. The gas meter should be checked to make sure that it will supply enough gas to the heater and any other appliances that may be used on the same meter. The gas line from the meter will usually be of a larger size than the gas valve supplied with the heater. Therefore a reduction of the connecting gas pipe will be necessary. Make this reduction as close to the heater as possible. The heater and any other gas appliances must be disconnected from the gas supply piping system during any pressure testing on that system, (greater that . PSIG). The heater and its gas connection must be leak tested before placing the heater in operation. Do not use flame to test the gas line. Use soapy water or another nonflammable method. A manual main shut-off valve must be installed externally to the heater. WARNING Do not install the gas line union inside the heater cabinet. This will void your warranty.

Connect the manometer hose to the fitting. 5. Fire the heater. 6. The manometer must read 4 in. WC for natural gas, 11 in. WC for propane gas, while the heater is operating. 7. For adjustment, remove the Regulator Adjustment Cap and using a screwdriver turn the screw clockwise to increase - counterclockwise to decrease gas pressure. Table 7.

G 1-22-04 P/N 471048 17 24" DOOR 18" 6" 6" VENTILATION OUTDOOR INSTALLATION ONLY (See additional instructions for outdoor Power- Max units in PowerMax Appendix) For outdoor installation with built in vent top, the heater must be placed in a suitable area on a level, noncombustible surface. Do not install the heater under an overhang with clearances less than 3 feet from the top of the heater. The area under an overhang must be open on three sides. IMPORTANT! In an outdoor installation it is important to protect your heater from water damage. Ensure water is diverted from overhanging eves with a proper gutter/ drainage system. The heater must be set on a level foundation for proper rain drainage. Maintain minimum clearances as indicated below. Install a minimum of 4 feet below, and 4 feet horizontally from any opening to a building. The heater should not be installed closer than 6 inches to any fences, walls or shrubs at any side or back, nor closer than 18 inches at the plumbing side. A minimum clearance of 24 inches must be maintained at the front of the heater. Installation (contd.) STACK TYPE OUTDOOR VENT KIT IMPORTANT! When locating the heater, consider that high winds ...
