*CHECK GAS OUTLET (MANIFOLD) PRESSURE:
1. Be sure that the valve is in the “OFF” position before removing the pressure tap plug at the valve. With
the main burner operating, check the manifold pressure using a lower-pressure test set connected to the
1/8” NPT Outlet Pressure Tap. (Refer to Figures 9, 9a and 9b for each control valve type.) Controls No.
2A, 2B, 5B and 5D have combination valves with built-in appliance regulators. These regulators are
factory set and should not require adjustment. They should provide the correct manifold pressure at the
varying supply pressures noted in the Gas Pressure Table below. DO NOT EXCEED THE PRESSURES
SHOWN IN THE GAS PRESSURE TABLE.
2. If manifold gas pressure adjustment is required, remove the cover screw. (See Figures 9, 9a and 9b for
valve drawings.) Using a small screwdriver, turn the adjusting screw clockwise
to increase or counter
clockwise
to decrease the gas pressure to the burner.
3. Turn the valve back to the “OFF” position before removing the manometer and replacing the plug.
Repeat the gas leak test at the plug.
