COMBITHERM
VENTILATION & INSTALLATION REQUIREMENTS
1. A single gas Combitherm oven requires a minimum of
28 CFM 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. Failure 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
COMMONWEALTH OF MASSACHUSETTS ONLY.
An adequate ventilation system is required for commercial
cooking equipment. Information may be obtained by
writing to the National Fire Protection Association,
Batterymarch Park, Quincy, MA 02269. When writing refer
to NFPA No. 96.
Inadequate ventilation, or failure to ensure
an adequate supply of fresh air will result in
a high ambient temperature at the rear of the
oven. 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.
D A N G E R
Installation, air adjustment and/or
service work must be in accordance
with all local codes and must be
p
erformed by a certified service
technician qualified to work on
gas appliances.

FAILURE TO VENT THIS APPLIANCE
PROPERLY MAY BE HAZARDOUS TO
THE HEALTH OF THE OPERATOR.
Equipment damage, operational
problems and unsatisfactory baking
performance may also be the
consequence of improper venting.
Any damage sustained by a failure to
properly vent this 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.
C A U T I O N
To prevent malfunction or cause
negative back draft, DO NOT obstruct
exhaust flues or attach any flue
extension that will impede proper
burner operation.
