1. Pilot is on when burner is on.
2. MIN represents the LOW FIRE position.
3. OPEN represents the HIGH FIRE position.
4. POC represents Proof of Closure – otherwise known as Fuel Valve End Switch.
5. Recycling Interlocks are general one or more limits switches in series (High/Low gas pressure, Oil temperature, etc) that are used to stop
the burner when the limit switch opens and restart when the limit switch recloses.
6. Non-Recycling Interlocks are general one or more limits switches in series (High steam pressure, Low water, etc) that are used to
stop the burner when the limit switch opens and prevent it from restarting until both the limit switch recloses and the manual/remote reset
is activated.
7. CAST is defined as the Combustion Air Switch Test.
8. CAP is defined as the Combustion Air Prove.
9. Combustion Air Blower Terminals 6 & 7 are tied internally.

Caution: All safety limit switches should
be approved as limit controls and should
be wired directly in the circuit of the
Flame Safeguard control. The use of
electronic switches to close interlock
circuits may cause erratic operation.
Proper grounding is necessary.
Wiring base ground terminal
should be attached to grounded
bonding screw in cabinet
All wiring must comply with
regional and local codes.
Typical Mains connection
