Gas Pressure

WARNING

Exposure to a higher gas supply pressure may cause damage to the control, resulting in explosion or fire. Consult your local gas supplier and gas authorities. DO NOT PUT INTO SERVICE IF OVER-PRESSURIZATION HAS OCCURRED.

GSW Water Heating Company recommends that the gas supply pressure, as measured on the inlet side of the water heater control, be set at 7.0 in. w.c.(1.7 kPa) for natural gas and 11.0 in. w.c. (2.7 kPa) for propane gas. The above pres- sures must be measured during water heater operation. The gas control supplied with this water heater is designed for a maximum inlet pressure of 0.5 psi (14 in. w.c.). Do not exceed 0.5 psi (14 in. w.c.). The Flame GuardTM safety sys- tem is designed to operate at a manifold pressure of 5.0 in. w.c. (1.2 kPa) for natural gas and 10.0 in. w.c. (2.4 kPa) for propane gas.

Gas line purging

Gas line purging is required to eliminate air from the piping system. Purging should be performed by persons experi- enced in this type of gas service in compliance with the code having jurisdiction. Do not purge in confined areas or space where ignition may occur. To avoid risk of fire or explosion ensure the area is well ventilated and all sources of ignition are de-activated. Contact your local gas authority for local requirements.

Gas Leak Testing

Important: This water heater and its gas connection must be tested for leaks before placing the appliance in opera- tion. Perform a leak test at normal gas pressure. If the appli- cable code(s) require the gas lines to be tested at a pres- sure of 14 in. w.c. (3.5 kPa) or greater, the water heater and its manual shut-off valve must be disconnected from the gas supply piping system and the line capped. Test all connec- tions of the gas system with a chloride-free soap and water solution or equivalent leak test liquid. Bubbles will indicate leaks. Never use a match or open flame to test for gas leaks. A fire or explosion could result. If leaks exist repair as required and retest.

DO NOT light the burner before the tank is filled with water and you have confirmed that there are no leaks in the pip- ing and connections.
