• Avoid installation above gas ranges or stoves. (NR71-SV, NR66-SV)
• Avoid installation between the kitchen fan and stove. If oily
fumes or a large amount of steam are present in the installation
location, take measures to prevent the fumes and steam from
entering in the equipment. (NR71-SV, NR66-SV)
• Install in a location where the exhaust gas flow will not be
affected by fans or range hoods.
• Take care that noise and exhaust gas will not affect neighbors.
Avoid installation on common walls as the unit will make some
operational noises while it is running.
• Make sure that the location allows installation of the exhaust
vent as specified.
• For outdoor installation, use the outdoor vent cap.
If it is necessary to vent above the roof line in an outdoor instal-
lation, use high temperature sealant around the flue collar for
rain protection.
• Avoid installation where the unit will be exposed to excessive
winds.
• Before installing, make sure that the vent termination (or the
vent cap in an outdoor installation) will have the proper clear-
ances according to the National Fuel Gas Code (ANSI Z223.1).
