Venting Safety Guidelines
Installation must be done in accordance with all local and national codes. Use only materials which conform to local codes
in effect. Be sure power is disconnected before doing any electrical work. All duct work must be metal. Do not use plastic
duct. The range hood should never be exhausted into a wall cavity or an attic where an accumulation of grease
could become a fire hazard.
When the installation is completed, turn on the fan and make sure that there are no obstructions in the line.
Gas Line Installation
The Model 7100 / 9100 can be operated on either natural gas or liquid propane (LP) and are set for natural gas OR
propane (LP) gas at the factory. Be sure your range is correctly installed by a qualified serviceman or installer for the
type of gas on which it is to be used.
When preparing to install the 9100, be aware that there are several alternative locations for the gas supply pipe to enter
into the stove. For reasons of appearance you may want to conceal the gas supply pipe, and this can be achieved by
routing the supply pipe through knockouts located on the rear or at the bottom of the stove (see illustration below). To
use the alternative locations, the back panel must be disassembled and the selected knockout removed. Route the pipe
through the knockout and up to the manifold. Reassemble the back panel to the stove. Model 7100 has only one supply
pipe installation location. (see illustration below)
THE RANGE MUST BE INSTALLED IN COMPLIANCE WITH LOCAL CODES, AND IN THE ABSENCE OF LOCAL
REQUIREMENTS, THE INSTALLATION MUST CONFORM WITH THE NATIONAL GAS CODE.
