To prevent SERIOUS INJURY, DEATH, or
PROPERTY DAMAGE:
Installation, air adjustment and/or service
work must be in accordance with all local
codes and must be performed by a trained
service technician qualified to work on
gas appliances.
1.
A single gas Combitherm oven requires a
minimum of 28 CFM make-up air for both natural
and propane gas. The bottom of the oven allows
necessary air flow into the appliance necessary 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.
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.
N O T I C E
Inadequate ventilation, or failure to ensure an adequate air
flow may result in high ambient temperatures at the rear of
the appliance. High ambient temperatures can cause the
thermal-overload protection device on the blower motor
to trip resulting in severe damage to the blower motor.
