COMBINATION VALVE REGULATOR

ADJUSTMENT

WARNING: SHUT OFF THE GAS BEFORE SERVICING.

Accurate gas pressure adjustments can only be made with the gas on and the burner lit. If the incoming line pressure to the valve is less than the minimum stated, then the pressure cannot be set correctly.

The combination valve is preadjusted for natural or propane gas as specified on the rating plate. The natural gas rating is 4" W.C., and the propane rating is 10" W.C.

1. Turn the combination valve knob to OFF.

2.Remove the plug from the submanifold and install pressure gauge at this point.

3.Turn on the gas and light the pilot as outlined under Lighting Pilot in General.

4.Turn the combination valve to ON.

5.Set the thermostat so the burners will come on.

6.Read the pressure gauge. The manifold pressure reading should match the pressure rating on the data plate.

A. To adjust, remove the cap covering the manifold pressure adjustment screw. Turn the recessed manifold pressure adjustment screw counterclockwise to decrease pressure or clockwise to increase pressure.

7. Install the cap and check for proper operation.
