steam and water. The brass valve stem must be opened
fully to enable this feature If the valve is in any other
position, the ball will not seat.
PROOF OF CLOSURE - IF APPLICABLE TO YOUR
MODEL
1. Disconnect power to the boiler.
2. While the boiler is off, remove the common wire
to the proof of closure (POC) switch on the oil/gas
valve.
3. Restore power to the boiler. The boiler should
immediately lock out on alarm due to the POC
being disconnected.
4. Disconnect power and reconnect the POC wire.
5. Restore power to the boiler and reset any flame
programmer faults.
6. Cycle the burner and observe for proper
operation.

Cycle Testing

The boiler should be cycle-tested and automatically
allowed to go through its normal starting sequence
several times to verify that all components are
functioning accurately.
This will also verify that combustion is set properly so
that boiler light-off has a smooth transition from ignition
to main flame.
It is recommended that a minimum of 10 cycles should
be met without any flame failures, with combustion
readings comparable to the factory test fire sheet and no
interlocks causing the boiler to shutdown.

Daily Start-Up

To initiate daily start-up:
1. Turn Switch to On or Local (depending on
model). The blower/fan will start up and ramp to
high fire speed/rpm. The blower/fan will purge for
30 seconds, then ramp down to light off position
(near low fire). When stable, ignition sequence
begins.
2. As spark is generated inside the combustion

chamber, the pilot gas valve opens. There should
be an audible click of the pilot solenoid valve.
3. Once pilot flame is established, the main gas valve
will open. There should be an audible click from
the main gas valve solenoid valve. There may be a
slight whooshing sound as the main burner flame
lights.

Daily Shutdown

To initiate daily shutdown:
1. Turn switch to Off. If burner is currently on, the
unit will start ramping down to low fire before
turning off.
2. Gas valve will shut. The blower/fan may increase
speed briefly as the flow of gas is cut off. The
blower/fan will ramp to high-fire speed/rpm, and
continue to run there for a 15-second post purge.
