LIGHTING AND OPERATION
PILOT AND MAIN BURNER OPERATION
Follow the lighting instructions on page 21. When the pilot is
lit and operating properly, it should look like the adjacent illus-
tration. One flame will be directed at the pilot thermocouple, a
second flame is directed at the pilot thermopile and the third
will be emanating toward the burner. If the pilot flames do not
resemble the illustration above, see the instructions below for
pilot flame adjustment.
After the main burner ignites and has been in operation for a
few minutes, the flames should look like those in the illustra-
tion below. Note: Flame height will vary depending on the
firing rate but flames should be burning in all of the areas seen
in the illustration.
PILOT FLAME ADJUSTMENT
The pilot flow is factory set to maximum. The pilot
flame should envelope 3/8” to 1/2” of the thermocou-
ple and thermopile. See the illustration at the top of
this page. If the pilot flames do not resemble those
shown in the illustration, the pilot flame may be ad-
justed.
1. Locate the pilot adjustment screw on the valve re-
ferring the adjacent illustration.
2. Turn the adjustment screw clockwise to decrease
or counterclockwise to increase pilot flame.
