24 GAS SUPPLY INSTALLATION: The heater is shipped from the factory with the gas connection located on the left-hand side of the heater cabinet. Insert the pipe to the gas valve through the grommet in the cabinet side (see Figure 14.) A union should be installed outside the heater cabinet for easy removal of the gas manifold assembly during service. A CSA certified main gas shutoff valve must be installed outside the cabinet and within 6 feet of the heater. This valve must have an I.D. large enough to supply the proper amount of gas volume to the heater. See Figure 13. Figure 13 ATTENTION: Apply joint compound (pipe dope) Figure 14 sparingly and only to the male threads of pipe joints. Do not apply joint compound to the first two threads. Use joint compounds resistant to the action of lique- Supply fied petroleum gas. Do not overtighten the gas inlet Gas voltage inlet pipe or damage may result. Inlet ATTENTION : Do not use flexible appliance con- nectors on any gas connections unless the connector Bonding lug is CSA approved for outdoor installation, is marked with BTUH capacity (which must be equal to or Low voltage greater than the heater rated input) and the type of gas inlet (natural or LP). Reduction of gas supply pipe or tubing to the inlet of the heater gas valve must be made at the valve only and must match the valve inlet size (3/4" NPT). If more than one appliance is installed on the gas line, consult the local gas company for the proper gas line size. Questions on the installation of the proper gas line size can be directed to Hayward Technical Service. NATURAL GAS: The gas meter must have the capacity to supply enough gas to the pool heater and any other gas appliances if they are on the same pipeline (Example: 225 meter = 225,000 BTUH). If doubt exists as to the meter size, consult the local gas utility for assistance. Hayward will not be responsible for heaters that soot up due to improper meter and gas line sizing resulting in improper gas volume. PROPANE GAS: All propane gas tanks must be located outdoors and away from pool/spa structure and in accordance with the standard for storage and handling of propane gas, ANSI/NFPA 58 (latest edition) and applicable local codes. If the propane gas tank is installed underground, the discharge of the regulator vent must be above the highest probable water level. Propane tanks must have sufficient capacity to provide adequate vaporization for the full capacity of the equipment at the lowest expected temperatures. Consult a propane company expert for correct sizing. USE ONLY HAYWARD GENUINE REPLACEMENT PARTS Pomona, CA Clemmons, NC Nashville, TN Tel: 908-351-5400 www.haywardpool.com
