Figure 7.1 Intermittent Pilot Manometer Adjustment
Inlet Gas Pressure
Verify the inlet gas supply pressure by connecting a ma-
nometer to the inlet side of the valve. If the inlet gas pres-
sure is incorrect, do not adjust without specic approv-
al and instruction from the gas supplier. Changing inlet
pressure may effect other appliances in the residence.
Manifold Gas Pressure
To measure the manifold pressure, loosen the manifold
pressure tap with a small athead screwdriver, and con-
nect a manometer to the 1/8 in. manifold pressure tap on
the side of the valve. See Figure 7.1. Ignite the appliance
and ensure the pressure is between 3.2 - 3.7 in. for NG
and 9.5 - 10.5 in. for Propane water column.
Shut off Appliance
Remove the manometer and tighten the manifold pres-
sure tap.
B. Checking the Pressure
Fire Risk!
Explosion Risk!
Asphyxiation Risk!
WARNING
• High pressure will damage valve. Low pressure
could cause explosion.
• Check all ttings and connections with a non-
corrosive commercially available leak-check
solution. DO NOT use open ame.
Turn on the gas and electricity.
Gas Leak Test
•All connections must be tightened and checked for leaks
with a commercially available, non-corrosive leak check
solution. Be sure to rinse off the solution when done leak
