Installation Clearances
Minimum clearance for combustible and Non-Combustible
Construction : 1” (25mm) sides and 6” (152mm) rear. Suitable
for installation on combustible floors. Legs must be installed.
Preparation
1. Carefully remove unit from carton or crate. Burner tie
wires and other packing material should be removed
from units. On stainless steel units, the protective
material covering the stainless steel should be removed
immediately after the unit is installed.
2. This unit must be mounted on the factory-supplied legs
when installed. Refer to section titled LEG INSTALLATION
for details.
3. Provide adequate clearances for proper operation and
servicing of the appliance.
4. For your safety: keep the appliance area free and clear
from combustibles.
5. These units must be installed under an adequate
ventilation system. Refer to sections titled “Ventilation”
and “Air Supply” for further instructions.
Ventilation
This appliance must be installed in a location in which the
facilities for ventilation permit satisfactory combustion of gas
and proper venting. Proper ventilation is imperative for good
operation of the appliance. The ideal method of ventilating
equipment is the use of a properly designed ventilating
canopy, which should extend at least 6”/152mm beyond all
sides of the appliance (except against the wall if the canopy
is a wall installation). This is usually part of a mechanical
exhaust system.
Air Supply
1. It is necessary that sufficient room air ingress be allowed
to compensate for the amount of air removed by any
ventilating system. Otherwise a subnormal atmospheric
pressure will occur, affecting the appliance operation
adversely and causing undesirable working conditions.
2. Appliances shall be located so as not to interfere with
proper circulation of air within the confined space. All gas
burners and pilots require sufficient air to operate.
3. Large objects should not be placed in front of the
appliance, which might obstruct the airflow through
the front. Do not obstruct the flow of combustion and
ventilation air.
4. Do not permit fans to blow directly at the appliance, and
wherever possible, avoid open windows adjacent to the
appliance sides and back; also wall type fans which create
air cross-currents within the room.
Installing Under Ventilation Canopy:
Too strong a pull through the exhaust system will pull heat
out of the oven too rapidly and cause uneven baking (strong
bottoms and light tops).
All ovens, operating under a ventilating canopy should be
equipped with a canopy flue diverter assembly (supplied to
offset too strong a pull.
Installing with Direct Ventilation
Wherever a direct flue is unavoidable, it is necessary that:
1. The draft diverter shipped with the oven is installed.
2. An adequately sized draft regulator (barometric damper)
must be installed in the flue line as close to the oven
connection as possible.
An adequately sized prefabricated metal vent should rise at
least 10 feet (3m) above the roof of the building in which it is
installed, or 10 feet (3m) above any proximate higher structure,
and should be equipped with a well designed vent cap.
Never, under any circumstances, install a damper or place
steel wool in an oven flue.
