INSTALLATION (cont’d)
PILOT FLAME ADJUSTMENT
If the pilot flame is low and does not engulf the bulb of the
mercury flame sensor, the system will not energize the
main valve. If pilot gas pressure is too high, gas will sputter
past the ignition electrode, and may not ignite. High pilot
gas pressure may also cause the flame to lift off the
burner, causing the flame sensor bulb to sense "low" heat.
To adjust the pilot gas pressure, remove the cover screw
(see fig. 6). To REDUCE pilot pressure, turn the pilot
adjust screw (beneath the cover screw) clockwise. To
INCREASE pilot pressure, turn the pilot adjust screw
counterclockwise. Replace and tighten cover screw.
PRESSURE REGULATOR
ADJUSTMENT
The pressure regulator has been factory adjusted (see
control for specific setting). Although additional adjust-
ments will not normally be necessary, you may adjust the
regulator. Do not force the adjusting screw beyond the
limits that it can easily be adjusted.
1. Energize valve to ignite main burner.
2. Remove "Reg. Adj." cover screw (see fig. 7).
3. To DECREASE outlet pressure, turn the adjusting
screw (beneath the cover screw) counterclockwise.
To INCREASE outlet pressure, turn the adjusting
screw clockwise.
4. Replace the cover screw. Cycle the valve two or three
times to verify regulator setting.
