OPERATION AND SERVICE

Manifold Pressure Adjustment

The main gas regulators are found beneath the silver or black cap screws. (Natural Gas valves have silver caps; Propane valves have a black caps). Remove the caps to access the outlet (manifold) pressure adjustment screw. IMPORTANT: Ensure that the outlet pressure matches the manifold pressure that is listed on the water heater rating plate.

•Natural Gas valves are factory preset to 3.5 inches W.C. The full rate outlet pressure range is between 3 and 5 inches W.C.

•Propane (LP) valves are factory preset to 10.0 inches W.C. The full rate outlet pressure range is between 8 and 12 inches W.C.

•Caution: Always test the manifold pressure at the outlet when the gas is flowing.
