Observe all warnings on the Operating Instructions
label and turn on the gas and main electrical power
(circuit breaker) to the unit.
4.
If the unit has the optional gas pressure switches, the
low pressure gas switch will need to be reset.
5.
Turn the Brute on at the On/Off switch.
6.
The Brute unit will begin the start sequence. The
blower and pump will energize for the pre-purge
period, then the ignition sequence will start. After all
safety devices have been verified, the gas valve will
open. If ignition doesn’t occur, turn off the Brute, and
check that there is proper gas supply. Wait 5 minutes
before restarting.
7.
Follow Section 8.10 for set up of Combustion Mixture.

After placing the appliance in operation, the Burner
Safety Shutoff Device must be tested
:
•
Close the gas shutoff valve with the burner operating.
•
The flame will go out and the blower will
continue to run for the post purge cycle. One
or three additional attempts to light will follow.
Each cycle will include pre-purge, ignitor on,
valve/flame on, and post purge. Ignition will
not occur because the gas is off. The ignition
control will lockout after a single try or a third try
depending on the controller model.
•
Open the gas shutoff valve. Reset the boiler
control by pressing the Reset button on the
control or on the display. If the unit has the
optional gas pressure switches, you will need
to reset the low pressure switch. Find the low
pressure switch and press the reset button. Restart
the appliance. The ignition sequence will start
again and the burner will start. The appliance will
return to its previous mode of operation.
DANGER
If you detect any odor of gas, or if the gas burner
does not appear to be functioning in a normal
manner, CLOSE THE MAIN SHUTOFF VALVE.
Do not shut off the switch. Contact your heating
contractor, gas company, or factory representative.
