Typically, the top 3/8” or 1/2” of the thermopile should
be engulfed in the pilot flame. (Fig. 18)
To adjust pilot burner, turn pilot screw marked “pilot” for
proper flame size.
The air shutter is set at the factory, therefore there is no
adjustment necessary.

Electronic Ignition System
The Electronic Ignition burner/control system consists
of:
•
main burner
•
gas orifice
•
hot surface pilot burner
•
24VAC valve with transformer
Taking care of the Electronic Ignition units is almost
identical to taking care of the Standing Pilot models.
(See Maintenance sections on page 16.) The hot sur-
face ignitor is the only component which requires EX-
TREMELY DELICATE HANDLING. The ignitor is made
of silicone carbide which is a very brittle material. DO
NOT TOUCH THE HEATING PART OF THE IGNITOR
WITH YOUR FINGERS!

Flame Adjustment
For units equipped with Hi/Lo valves flame adjustment
is accomplished by rotating the Hi/Lo adjustment knob
located near the center of the gas control.
It is important to periodically perform a
visual check of the pilot and the burner
flames. (Figs. 18 and 20)
