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 psig (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.
Test piping as follows:
Pressure 1/2 PSIG (14" W.C.) or less - isolate heater by closing the manual shut-off valve prior to applying
pressure.
Pressure in excess of 1/2 PSIG (14" W.C.) - The heater must be disconnected from the gas system.
Water heaters having gas train components that have diaphragms in their construction are supplied with a bleed
line connection that must be connected to the outside atmosphere as required by the National Fuel Gas Code. Under
NO circumstances shall bleed lines terminate in the gas utilization equipment flue or exhaust system.
Burner Manifold Pressures. The gas pressure regulator supplied with the heater is factory set to provide a manifold
pressure, as measured with a manometer, of 3.7 in. W.C. for Natural Gas and 10.5 in. W.C. for Propane. If adjustment
is required to obtain these pressures remove cap and turn screw clockwise to increase pressure, counter- clockwise
to decrease pressure.
