The gas pressure regulator must be installed in the gas line – failure to install a pressure regulator will void the equipment
warranty. The regulators supplied with convection ovens have 3/4” NPT connections; the regulators adjusted at the factory for
5” W.C (water column) manifold gas pressure (natural gas) or 10” W.C. manifold gas pressure for propane gas operation.
Before connecting the regulator, check the incoming line pressure – as these regulators can only withstand a maximum inlet pressure
of 14” W.C. (1/2 PSI); exceeding this pressure will damage them. Visually double check any installer-supplied intake pipes and/or blow
them out using compressed air to clear any dirt or debris, threading chips, or other foreign matter – before installing a service line.
Those particles will clog gas orifices when gas pressure is applied. Compounds used on threaded joints of this appliance piping must
be resistant to the action of NP and LP gas and provide a gas tight seal to prevent leaks. If the gas supply line pressure is greater than
this amount, a step-down regulator will be required. A gas flow direction arrow is cast into the body of the regulator to minimize
installation error – it should point downstream to the appliance. The blue air vent cap on the top of the regulator is part of the
regulator and should not be removed.
Any adjustment to the regulator must be made only by qualified and licensed service personnel with the proper calibrated test
equipment. Gas connections should be performed by a qualified licensed contractor.
Ovens with Casters -
In order to be able to service this appliance, it must be installed with the locking front casters supplied,
a flexible connector complying with ANSI Z21.69.CGA6.16 and a quick disconnect device complying with ANSI Z21.41CGA 6.9.
Adequate means must be provided to limit the movement of the appliance without depending on the connector and the quick
disconnect device or its associated piping to limit the appliance movement.
All American Range Corporation appliances are adjusted and tested before leaving the factory, effectively matching them to
appropriate atmospheric conditions. We recommend that adjustments and calibrations are performed upon installation to assure
proper operation of the unit and avoid possible problems caused by rough handling or vibration during shipment. This work must be
performed only by qualified service personnel. These adjustments are the responsibility of the customer and/or dealer and are not
covered by warranty.
Check all gas connections for leaks with a soapy water solution before lighting the oven.
DO NOT USE AN OPEN FLAME TO
CHECK FOR LEAKS!
Putting an open flame beside a new gas connection is extremely dangerous and may result in serious injury
or death.
