MODEL #55345-RF: PRESSURE TEST - MANIFOLD & INLET PRESSURE
IMPORTANT NOTICE: A pressure check tap for both the manifold (outgoing) and inlet (incoming) pressure has been
incorporated into the valve by HONEYWELL Controls. The left pressure tap is the manifold pressure and the right pressure
tap measures the incoming pressure. Follow the instructions below for proper pressure testing procedures.
NOTE: Both the inlet and outlet pressure taps have a captive screw.
1. Be sure the gas control knob is in the PILOT position.
2. Light the pilot.
3. Loosen, but do not remove the outlet tap captive screw.

GAS LEAK TEST:
1. Paint the pipe connection upstream of the gas valve with a rich soap and water solution. Bubbles indicate a
gas leak.
2. If a leak is detected, tighten the pipe connections.
3. Light the main burner.
4. With the main burner in operation, paint the pipe joints (including adaptors) and valve inlet and outlet with a
rich soap and water solution.
5. If another leak is detected, tighten the adapter screws, joint, and pipe connections.
6. Replace the part if the leak cannot be stopped.
