BOILER CONTROLS (Inside Cabinet)
(Continued)
Water Level Control - While ON, briefly open the water level control once each week to
remove any sediment that might accumulate.
Safety Valve
-
This valve will release (pop off) if the boiler has too much pressure.
Once a week, this valve should be tripped during operation to make sure
it functions properly.
1. START UP - BOILER OPERATION WITH STANDING PILOT IGNITION
Open manual gas shut off supply valve and if the appliance has a manual blowdown valve,
close it. Open cabinet door and turn ON power switch located on left side. Green pilot light will
come on, water will begin to enter boiler and required water level will be reached in about three
minutes. Observe water gauge glass to verify.
The dial on the combination gas control valve has three positions (ON-PILOT-OFF) for manual
gas control of main burners and pilot. Turn DIAL to PILOT. Depress dial and light pilot burner
located on centre main burner of boiler. Maintain dial in depressed position for about 30
seconds and release. Observe that the pilot burner flame stays on. If at any time the flame
should become extinguished, a 5 minute period of complete shut off of gas supply is required
before relighting.
Turn dial to ON and burners should ignite. Steam generation will now commence and be
completed in approximately 15 minutes. Steam generation should reach approximately 11 psi
as indicated on the pressure gauge on the boiler.
2. START UP - BOILER OPERATION WITH ELECTRONIC IGNITION
Open manual gas supply valve.
Open cabinet door and turn main power switch ON. Green pilot light will come on, water will
begin to enter boiler and required water level will be reached in about 3 minutes. Observe
water gauge sight glass to verify.
The dial on the gas combination control valve has 2 positions (ON and OFF).
ON - [Rotated counterclockwise] permits gas to flow to the pilot and main burner.
OFF - [Rotated clockwise] prevents gas flow to pilot and main burner.
NOTE: Units are shipped with the control in the ON position.
