1.3 — Operating Controls
The control panel contains a flame safeguard programming control, motor starters, relays, time delays, and ter-
minal strips mounted internally on a panel subbase. Lights, switches, potentiometers, a control circuit breaker,
and flame safeguard displays are mounted externally on the panel as indicated:
1.4 — Flame Safeguard Controls
The flame safeguard programmer incorporates a flame sensing cell (scanner) to shut down the burner in the
event of pilot flame or main flame failure. Other safety controls shut down the burner based on sequence of oper-
ation as shown in the manufacturer’s flame safeguard manual.
Component
Details
On-Off Burner Switch
For gas or oil only.
Fuel Selector Switch
Gas-Off-Oil
For combination gas-oil burners only.
a) Gas Position: Selects gas as the firing fuel.
b) Off Position: Burner off.
c) Oil Position: Selects oil as the firing fuel.
NOTE:
When changing from oil to gas fuel, allow the programmer to com-
plete post-purge and shutdown before moving the selector switch to the gas
position. This will allow the interlock circuit to de-energize at either the oil-
air pump or the compressor.
Control Circuit Breaker
Supplementary low overcurrent protection only. No larger than 15 amps.
Auto-Manual Modulation Selector
Switch
a) Auto Position: Selects boiler modulation control.
b) Manual Position: Selects 135 ohm potentiometer for manual modulating
control.
Manual Modulating Control 135 ohm
Increases or decreases the burner firing rate manually.
Signal Lamps
a) Power On (white): Illuminates when the control circuit is energized (pow-
ered).
b) Ignition (amber): Illuminates when the ignition transformer is powered,
and gas pilot valve is energized (open).
c) Main Fuel (green): Illuminates when the main fuel valve or valves (gas or
oil) 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. Fail-
ure to follow this instruction may result in serious personal injury or death.
