AIR SUPPLY AND VENTILATION
The area in front of, around and above the appliance must be kept clear to avoid any obstruction of the
flow of combustion and ventilation air. Adequate clearance must be maintained around the appliance for
easy servicing.
Provision should be made for any commercial, heavy duty cooking appliance exhaust combustion
waste products to the outside of the building. Usual practice is to place the appliance under an exhaust
hood, which should be constructed in accordance to the local codes.
Strong exhaust fans in this hood or in the overall air conditioning system can produce a slight vacuum in
the room and / or cause air drafts, either of which can interfere with the pilot or burner performance and
could be difficult to diagnose. Air movement should be checked during installation. Air openings or
baffles may have to be provided in the room, if pilot or burner outrage problem persists.
GAS CONNECTION
The gas supply (service) line must be the same size or greater than the inlet line of the appliance.
COOKING PERFORMANCE GROUP ranges and ovens use a ¾" NPT inlet. Sealant on all pipe joints
must be resistive to LP gas.
MANUAL SHUT OFF VALVE
This installer supplied valve must be in the gas service line ahead of the appliance regulator in the gas
stream and in a position accessible in the event of an emergency.
PRESSURE REGULATOR
Commercial cooking equipment must have a pressure regulator on the incoming service line for safe
and efficient operation, since service pressures may fluctuate on local demand. A pressure regulator is
packed inside every
COOKING PERFORMANCE GROUP range.
Failure to install the pressure regulator will void the appliance warranty.
The regulators supplied along with Cooking Performance Group appliances, will have ¾" inlet/outlet
openings and are adjusted at the factory for 5" WC (natural gas) or 10" WC (propane gas) depending
on customer's ordering instructions.
Prior to connecting the regulator, check the incoming line pressure, as these regulators can only
withstand a maximum pressure of ½'' psi (14" WC). If the line pressure is beyond this limit, a step down
regulator will be required.
The arrow shown on the bottom of the regulator body shows the gas flow direction, it should point
downstream to the appliance. The red air vent cap on the top is part of the regulator and should not be
removed.
Any adjustments to the regulator should be made by qualified service personnel only with the proper
equipment.
CONNECTIONS
Please check installer supplied intake pipes visually and / or blow them with compressed air to clear
any dirt particles, threading chips or any other foreign matter before installing a service line. When gas
pressure is applied, these particles could clog orifices.
All connections must be sealed with a joint compound suitable for LP gas, and all connections must be
tested with a soapy water solution before lighting any pilots.
