Gas Supply Connections, Model No Nat Pro

(g)Any improper operation of the common venting system should be corrected so the installation conforms with the latest edition of the National Fuel Gas Code, ANSI Z223.1. When re-sizing any portion of the common venting system, the com- mon venting system should be re-sized to approach the minimum size as determined using the appropriate tables in Chapter 10 and in Appendix G of the National Fuel Gas Code, ANSI Z223.1 and CAN/CSA-B149.

Gas Supply Connections

The inlet gas connection to the heater gas valve is 1/2". Provide an adequate gas supply line according to Table F below.

Gas piping must have a sediment trap ahead of the heater gas controls, and a manual shut-off valve locat- ed outside the heater jacket. All gas piping should be tested after installation in accordance with local codes.

CAUTION: The heater and its manual shut off valve must be disconnected from the gas supply during any pressure testing of that system at test pressures in excess of 1/2 psi (3.45 kPa). Dissipate test pressure in the gas supply line before reconnecting the heater and its manual shut off valve to gas supply line. FAILURE TO FOLLOW THIS PROCEDURE MAY DAMAGE THE GAS VALVE. OVER PRESSURED GAS VALVES ARE NOT COVERED BY WARRANTY. The heater and its gas connections shall be leak tested before placing the appliance in operation. Use soapy water for leak test DO NOT use open flame.

NOTE: Do not use teflon tape on gas line pipe thread. A flexible sealant suitable for use with Natural and Propane gases is recommended.

NOTE: These heaters are also certified to operate on Propane gas, when equipped with the combination gas valve and orifices (pilot and main burners) sized for Propane gas.
