5.3 Semi-Annual Checks and Service

Check Burner Manifold Pressure

This task should be performed by qualified service personnel only.
1. Ensure that the gas valve knob is in the OFF position.
2. Remove the pressure tap plug from burner manifold.
(see photo).
3. Insert the fitting for a gas-pressure measuring device
into the pressure tap hole.
The frypot must be filled with shortening or
water during this procedure.
4. Place the gas valve in the PILOT position and light. When the
burner lights and continues to burn, note gas pressure reading
and compare to the accompanying tables.
5. To adjust burner gas pressure, remove the cap from the gas
valve regulator adjustment screw.
6. Increase the setting on the thermostat until the burner comes on.
7. Monitor the gas pressure reading on the man-ometer or
pressure gauge.
8. Adjust the gas valve regulator adjustment screw to obtain the
prescribed pressure. See the Rating Plate. Turning the screw
clockwise increases pressure, counterclockwise decreases
pressure.
