OPERATION AND SERVICE

GAS CONTROL VALVE

This gas valve is a 24 volt AC combination-step opening valve. It includes two valves assembled in parallel, connected by a wiring harness. Note that the valves have fixed pressure regulation and are not adjustable. However, the manifold (outlet) pressure is adjustable as described on the next page.

IMPORTANT:

For complete device shut-off, both gas control knobs must be in the OFF position.

Both gas control knobs must be in the same position for operation or shutoff.

Do not alter or remove the wiring harness.

Do not apply a jumper across the valve lead wires or short them together.
