STARTUP AND CHECKOUT
GAS COCK SETTINGS
The Lite-Rite gas cock knob has three settings:
OFF, which prevents any gas from passing through
valve to e.ither main or pilot burner.
PILOT, which permits gas to flow to pilot burner only
ON, which permits gas to flow to both main and pilot
burners when the thermostat calls for heat.
PILOT LIGHTING PROCEDURE
1.
Slightly depress Lite-Rite gas cock knob and turn
clockwise to OFF.Wait 5 minutes for all unburned
gas to vent.
WARNING
Remember that liquefied petroleum (LP) gas is
heavier than air and will not vent upward
naturally. Do not light pilot or operate electric
switches, lights, or appliances until you are sure
work area is free of gas. Failure to follow these
instructions may result in an explosion.
2.
Turn the Lite-Rite knob to PILOT, depress it com-
pletely, and light the pilot burner while holding it
down. Hold the knob down about one minute. If
the pilot goes out when the.knob is.released,
repeat steps 1 and 2.
3.
Turn the knob to ON, and set the thermostat or the
dial on the V504/V524. operator above room tem-
perature to turn on main burner.
GAS LEAK TEST
WARNING
DO NOT OMIT THIS TEST
With main burner in operation, paint gasket lines
between operator, pressure regulator or cover
plate, and main valve with rich soap and water
solution. Bubbles indicate gas leakage. To stop
leak, tighten assembly screws or, if necessary,
replace gasket.
CHECKOUT
Place the system into operation, and observe through
one complete cycle to be sure all controls function
properly. With V504/V524 operator, make sure burner
comes on when room temperature drops below the dial
setting, and the system maintains the desired
temperature.
