Control
Description
On-Off Burner Switch
To manually turn the burner on or off.
Fuel Selector Switch
Gas-Off-Oil
Gas position: Selects gas as the firing fuel.
Off position: Burner is off.
Oil position: Selects oil as the firing fuel.
Control Circuit Breaker
Supplementary low overcurrent protection only. No larger than 15 amps.
Auto-Manual Modulation
Selector Switch
Auto position: Selects boiler modulation control. In this position, the burner will
operate automatically in response to load demand.
Manual position: Selects 135 ohm potentiometer for manual modulating control.
Manual Modulating Control
135 ohm (for full modulation burners only) increases or decreases the burner
firing rate manually.
Signal Lamps
a) POWER ON (white): illuminates when the control circuit is energized
(powered).
b) IGNITION (amber): illuminates when the ignition transformer is powered, and
the pilot valve is energized (opened).
c) MAIN FUEL (green): illuminates when the main fuel valve or valves are
energized (open).
d) FLAME FAILURE (red): illuminates when the flame safeguard system fails to
detect pilot or main flame.
Read the flame safeguard manual and fully understand its contents before attempting to operate this
equipment. Failure to do so may result in serious personal injury or death.
