Gas Control Valve and
Burner Orifice
Remove the following:
a. Hose from the sediment trap.
b. Sediment trap with pipe nipple from the inlet of the
gas control valve.
c. Igniter from burner box.
d. Clear
fl
exible tube from the copper tube on the

BURNER ORIFICE:
Remove burner ori
fi
ce. Slide the burner plate from the
four threaded burner mounting studs. See Fig. 27.
Transformer
The transformer (Fig. 30) reduces the main power
supply voltage to 24 VAC. The 24 VAC is sent through
the thermostat (if used) or directly to the ignition con-
troller. Once the ignition controller receives 24 VAC,
an ignition cycle begins. The red LED will come on.
If the transformer is receiving main power voltage, but
24 VAC is absent from its output terminals, the trans-
former is defective. The brood heater will not operate,
nor will the red LED on the burner box door be on.
