LIGHTING INSTRUCTIONS FOR INTERMITTENT ELECTRONIC IGNITION
WITH NON-COMBINATION GAS VALVE.
This boiler is equipped with an ignition device, which automatically lights the pilot. Do not try to light the
pilot by hand. Before turning on the electrical power switch, be sure all gas supply lines are purged of air
and power supply to control is the correct voltage.
If the pilot or main burners are not lit or the control system is locked-out due to flame failure, close the
main and pilot gas shut-off valves and call your service technician or gas supplier. If you smell gas,
STOP! Follow “A” in the safety instructions in
Section 2
.
Check Control Operation
1. STOP! Read the safety instructions in
Section 2
.
2. For 100% shut off check, close main and pilot
manual gas shut off valves, turn off all electric
power to the boiler and wait for five minutes to
clear out any gas.
3. Then smell for gas, including near the floor. If
you smell gas, STOP! Follow safety instructions
in
Section 2
. If you don’t smell gas, go to the
next step.
4. Set the thermostat above room temperature
and turn on all electric power to the boiler to
energize the electronic ignition and pilot valve.
After a few seconds, the control system
should “lockout” and all functions are off.
5. To take the control system out of “lockout”
either press the reset button or interrupt power
to the boiler, depending on the boiler
controller. Some controllers will retry ignition
automatically after 5 minutes lockout.

off valves.

flame will ignite the gas as it exits the main
burner ports.
