Operating Instructions
STOP!
Read the safety precautions on page 7 of this
manual.
1.
Wait five (5) minutes to clear out any gas. Then
smell for gas, including near the floor. If you smell
gas, STOP! Follow "B" in the safety information on
page 7. If you do not smell gas, go to the next step.
2.
Locate the pilot assembly by looking through the
access viewing port (Fig. 7,
Pos. 1
) on the burner
front plate.
3.
Turn the gas control knob (Fig. 8,
Pos. 1
)
counterclockwise to “ON“.
4.
Turn on the electrical power to the application.
5.
Set the thermostat to the desired setting to activate
the boiler (Thermostat should be at least 10 °F
above the desired room tmeprature).
6.
The ignition control should initiate sparking at the
pilot. The pilot should light and then the main
burners should light. If the main burners do not light,
shut off the main gas piping shutoff valve. Shut off
all electric power to the appliance and call your
service technician or gas supplier.
7.
If the main burners light, then the gas fittings, union
and orifices must be tested for leaks with a soap and
water solution. If no leaks are found then go to step
9. If any leaks are found, turn off gas control knob
(Fig. 8,
Pos. 1
) clockwise to “OFF“. Turn off all
electric power to the appliance, set the thermostat to
lowest setting.
8.
Repair leaks. Repeat steps 1 through 7.
9.
Check the supply pressure while the boiler is
running. Pressure must be between 4.7 and 10.5
inches water column for Natural gas or 11 and 13
inches water column for Propane gas. Record
supply pressure on the boiler start-up procedure.
