AIR SUPPLY
Installation of this appliance must include a
provision for an adequate flow of fresh air for gas
combustion. This requirement must be observed
by the installer as well as the operator. The rear of
the appliance provides air supply access for gas
combustion and must be kept clear at all times
.
Make certain the installation maintains adequate air
ventilation to provide cooling for electrical and gas
components. The area around the appliance 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 control components and
will void the warranty.
Local and the National Fuel Gas Code provide
rules for determining the amount of fresh air
necessary for combustion and ventilation of
commercial cooking appliances. The codes will help
determine if additional outside air may be necessary
to meet health and safety regulations.
