Liquid Propane Gas Requirements (Cont’d)
WARNING:
For Pr
opane Gas Models: Your pizza oven is designed to operate on L.P.
(propane) gas pressure regulated at 11” water column. The regulator(s) supplied with
the pizza oven is set to this pressure and must be used.
Connection:
The Type I (Q.C.C.1) cylinder valve is recognizable by the large
external thread on the outlet part of the valve. Standard valves do not have
these exterior threads. Any attempt to fit the regulator(s) with anything other
than the mating Type I (Q.C.C.1) connector, (recognized by the large plastic
coupling nut) will negate the important safety features designed into the Type I
(Q.C.C.1) system. Fitting a standard #510 P.O.L connector, will not provide the
flow control or temperature shut-off safety features built into the complete
Type I (Q.C.C.1) system.
This regulator is equipped with the Type I (Q.C.C.1), quick
closing connection system, which incorporates the following features:
• Will not allow gas to flow until a positive seal has been made.
• Has a thermal element that will shut off the flow of gas if subjected to temperatures
between 115° and 150°C (240° & 300°F).
• Has a flow limiting device which, when activated, will restrict the flow of gas to 10
cubic feet per hour (25000 BTUs).
To connect the LP regulator hose assembly to the LP tank, first make sure the main
valve on the tank is completely closed. Make sure also that the control valves on the
pizza oven are OFF. Thread the regulator inlet over the tank valve. Use care to
ensure proper alignment of the threaded coupler and avoid cross-threading or
damaging the coupler. Turn the coupler clockwise until tightened up, but do not
over-tighten.
After connecting a fresh LP tank, you may need to purge air from the system. Before
lighting, open the main valve on the tank. Turn one of the burner control valves on
the pizza oven to the HIGH position for about 15 seconds to purge air from the
system. Turn the control valve on the pizza oven OFF and wait 5 minutes for any gas
to clear. Finally, continue with the normal lighting procedure.
Troubleshooting :
If the large thermally sensitive coupling nut is exposed to
temperatures above 115°- 150°C, it will soften and allow the regulator probe to
disengage from the cylinder valve, thereby shutting off the flow of gas. Should this
occur: do not attempt to reconnect the nut. Remove the entire regulator assembly
and replace it with a new one. The cause of the excessive heat should be
determined and corrected before operating the pizza oven again.
