Intermittent Pilot Operating Instructions
The intermittent pilot (120/24 volt system) is ON when the main burner
is ON. When the main burner is OFF the intermittent pilot is OFF.
IP-Model Pilot (Figure 44)
This fireplace is using a Honeywell "Smart Valve" system for intermittent
pilot ignition.
On a call for flame the control turns on a 24 volt mini hot surface ignitor
which lights a pilot that in turn lights the main burner.
Pilot Flame Adjustment (Figure 45)
The pilot flame should envelop 3/8 to 1/2 inch (10 to 13mm) of the tip
of the flame rod. (See Figure 44)
To adjust:
1. Remove the pilot adjustment cover screw.
2. Turn the inner adjustment screw clockwise
to decrease
or counterclockwise to increase pilot flame. Pilot adjust-
ment is shipped at full flow rate. Turn the inner adjustment screw
clockwise
if the inlet pressure is too high.
3. Replace the cover screw after the adjustment to prevent gas
leakage.
