Double-check any installer-supplied intake pipes visually and/or blow them out with compressed air to
clear any dirt particles, threading chips, or other foreign matter before installing a service line. Those particles will
clog orifices when gas pressure is applied.
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.
FELXIBLE COUPLINGS, CONNECTORS AND CASTERS
If the unit is to be installed with flexible couplings and/or quick-disconnect fittings, the installer must use a
heavy-duty, AGA design-certified commercial flexible connector of at least ¾” NPT (with suitable stain reliefs).
The flexible connector must comply with the standard for Connectors for Movable Gas Appliances, ANSI Z21.69
(or latest edition) CSA 6. 16 (or latest edition) and a quick-disconnect device that complies with the standard for
quick-disconnect devices for use with Gas Fuel should comply with ANSI Z21.41(or latest edition) CSA 6.9 (or
latest edition). If disconnection of the restraint is necessary, make sure to reconnect restraint after the appliance has
been returned to its originally installed position. Domestic gas or water connectors are not suitable.
Restraining device may be attached to the back frame/panel of the unit.
If the unit is to be installed with casters, a flexible connector must be used and the same ANSI standards
apply. Locking front casters are provided to limit the movement of the appliance without depending on the
connector or associated piping. A suitable strain relief must be installed with the flexible connector.
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 pilots.
INITIAL PILOT LIGHTING
All Imperial Mfg. appliances are adjusted and tested before leaving the factory, effectively matching them
to sea level conditions. Adjustments and calibrations to assure proper operation may be necessary on installation to
meet local conditions, low gas characteristics, to correct possible problems caused by rough handling or vibration
during shipment, and are to be performed only by qualified service personnel. These adjustments are the
responsibility of the customer and/or dealer and are not covered by our warranty.
Check all gas connections for leaks with a soapy water solution before lighting any pilots. DO NOT USE
AN OPEN FLAME TO CHECK FOR LEAKS! Putting an open flame beside a new gas connection is extremely
dangerous. Before lighting any pilots, make sure that burner valves and thermostats are turned “off”.
A.
TOP BURNERS
All top section burners are equipped with constant-burning pilots. These are to be manually lighted
immediately after the gas is turned on and the system checked for leaks. Top burner pilots are provided for
each burner and can be rechecked for proper adjustment down through the top grate. Adjustments can be made
with a screwdriver to the pilot valve accessible through the valve cover.
B.
GRIDDLES
Griddle pilots can be ignited through the front of the valve panel using a long match. The pilot flame
adjustment valve can be accessed through the front valve panel and adjusted using a flat tipped screwdriver.
C.
UNIT BROILERS
Broiler pilots can be accessed through the openings in the front cover panel. Pilot flame adjustment valves
can be accessed through the front valve panel and adjusted using a flat tipped screwdriver.
CAUTION
When lighting pilots and checking for leaks, do not
Stand with your face close to the combustion chamber
.
