VENTILATION & INSTALLATION REQUIREMENTS
1. A single gas Combitherm oven requires a
minimum of 28 C M make-up air for natural and
propane gas. Kitchen ventilation must include a
provision for an adequate flow of fresh air for
gas combustion and to prevent a negative-
pressure condition. The bottom of the oven
provides air supply access for gas combustion
and must be kept clear at all times.
DO NOT obstruct or restrict ventilation nor the
air flow required to support combustion.
2. DO NOT obstruct the flow of the exhaust flue at
the top rear of the oven. It is especially critical
that gas supply piping and electrical support
cord and/or receptacle be routed away from the
path of the hot combustion fumes.
3. Make certain the oven installation maintains
adequate air ventilation to provide cooling for
electrical and gas components. The area around
the oven should be clear of any obstructions
which might retard the flow of cooling air.
ailure to observe this caution may result in
damage to the components and will void the
warranty.
4. This oven cannot be direct vented.
5. Install the oven under a ventilation hood meeting
all applicable code requirements. Combustion
fumes must be vented in accordance with local,
state, or national codes.
Ventilating hoods and exhaust systems shall be
permitted to be used to vent appliances installed in
commercial applications.
Where automatically operated appliances are vented
through a ventilating hood or exhaust system equipped
with a damper or with a power means of exhaust,
provisions shall be made to allow the flow of gas to the
main burners only when the damper is open to a position
to properly vent the appliance and when the power means
of exhaust is in operation. IN ACCORDANCE WITH NFPA 54
COMMONWEA TH OF MASSACHUSETTS ON Y.
An adequate ventilation system is required for
commercial cooking equipment. Information may be
obtained by writing to the National ire Protection
Association, Batterymarch Park, Quincy, MA 02269.

properly vent th s oven are not
covered under warranty.
C A U T I O N
DO NOT USE CIRCULATING FANS
ON THE FLOOR. FLOOR FANS WILL
AFFECT BURNER OPERATION.
CAUTION
To prevent malfunction or cause
negative back draft, DO NOT obstruct
exhaust flues or attach any flue
extension that will impede proper
burner operation.
W A R N I N G
Inadequate ventilation, or failure to
ensure an adequate supply of fresh
air will result in a high ambient
temperature at the rear of the
appliance. An excessive ambient
temperature can cause the thermal-
overload protection device on the
blower motor to trip resulting in severe
damage to the blower motor.

An electrical wiring diagram is located behind the
control panel on the left side of the oven. This
appliance must be branch circuit protected with proper
ampacities, in accordance with the wiring diagram
located in the electrical compartment of the oven.

GAS SUPPLY & INSTALLATION REQUIREMENTS

COMBITHERM
The minimum size requirement for gas piping or a
flexible connector is 3 /
4- inch (19mm). or long runs
of gas piping, the pipe diameter must conform to the
tables in the National uel Gas Code, ANSI/N PA
Z223.1.
A listed gas shut-off valve must be installed
upstream of the appliance to shut off the gas supply
during servicing. The shut-off valve should be
accessible with the appliance in the normal
installation position.
If the oven or the oven stand is supplied with
casters, gas connection must be made with a flexible
connector that complies with the Standard for
Connectors for Movable Gas Appliances, ANSI
Z21.69; or in Canada, Connectors for Movable Gas
Appliances, CAN/CGA-6.16-M87. When using a
flexible connector, a quick disconnect device must
be used to comply with the Standard for Quick-
Disconnect Devices for Gas uels, ANSI Z21.41; or
in Canada, Quick Disconnect Devices for Use with
Gas uels, CAN1-6.9.
When a quick disconnect device and flexible
connector are used, a restraining device must be
installed to limit the movement of the appliance and
prevent damage to the connector or quick
disconnect. An example of a restraining device
would consist of a 2000 pound test, stainless steel
cable, attached to a structural member of the kitchen
wall behind the oven. The means of attachment
should consist of a q u i c k c o n n e c t sn a p s o t h a t
t h e o v e n c a n b e disconnected when the appliance
must be moved away from the wall.
The other end of the cable should be permanently
attached to the rear frame of the oven. The cable
should be of sufficient length so that no strain is
ever placed on the flexible gas connector in the
event of accidental movement of the oven without
properly disconnecting the gas connector. The
flexible connector should be routed to form a
downward "U" loop between the building gas
supply and the permanent attachment at the rear of
the oven.
The routing of the flexible connector must not be
made under the oven. Oven temperatures achieved
during operation are too hot for safe operation. Gas
piping should be installed from the point of gas
connection at the bottom, front of the oven to the
back of the oven where the flexible connector may
be safely used. See the illustration for the
recommended placement.
W A R N I N G
GAS PIPING MUST NEVER
BE INSTALLED TO RUN
UNDER THE BURNER.
