Installation, Operation and Care of
HGFR GAS-FLAMED ROTISSERIE OVEN
SAVE THESE INSTRUCTIONS
GENERAL
The model HGFR Series Gas-Flamed Rotisserie Oven features stainless steel interior and exterior for
ease of cleaning. Infrared ceramic gas burners efficiently roast the product. The rotisserie rotates the
product on spits as it revolves around the rotisserie oven. The product roasts evenly and self-bastes
throughout the cooking process. The drip pan's water bath system in the bottom of the rotisserie oven
adds moisture during roasting, catches the fat drippings (reducing the chance of fire) and facilitates
easy cleanup. This rotisserie oven has been exclusively designed to grill meat products. A see-through
window option is available.

INSTALLATION
Prior to installation, verify that the electrical service and gas supply (natural) agree with the
specifications on the machine data plate located on the right side of the rotisserie oven.
LOCATION
WARNING: THE ROTISSERIE OVEN SHOULD NOT BE ACCESSIBLE TO THE CUSTOMER;
HOT GLASS AND PARTS CAN CAUSE BURNS.
The equipment area must be kept free and clear of combustibles. Maintain clearances from combustible
and noncombustible construction of 3" (7.6 cm) at the sides and rear. If rotisserie oven is equipped with
the optional glass back, clearance from combustible and noncombustible construction must be 3"
(7.6 cm) at side and 15" (38.1 cm) from the rear of the rotisserie oven. The installation location must
allow adequate clearances for servicing (18" [46 cm] is recommended when used with leveling feet) and
for proper operation of the doors. The rotisserie oven is suitable for installation on combustible floors.
The rotisserie oven must be level for the rotor to operate properly.
The rotisserie oven must be installed so that the flow of combustion and ventilation air will not be
obstructed. The bottom of the rotisserie oven must be kept clear so that the air openings into the
combustion chamber are not obstructed. Make sure there is an adequate supply of air in the room to
allow for that required for combustion of gas at the rotisserie oven burners.
INSTALLATION CODES AND STANDARDS
In the United States, the gas rotisserie oven must be installed in accordance with: 1) State and local
codes; 2) National Fuel Gas Code, ANSI-Z223.1 (latest edition), available from American Gas

VENTING REQUIREMENTS
Refer to
be directly vented to a gas flue or exhaust. It should be operated under an exhaust hood that extends
at least 6 in. beyond the rotisserie oven's sides. Clearance above the rotisserie oven flue should allow
