• Avoid installation above gas ranges or stoves.

• 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.

• 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 clearances
according to the National Fuel Gas Code (ANSI Z223.1).

State of California: The water heater must be braced, anchored or strapped to avoid moving during an
earthquake. Contact local utilities for code requirements in your area or call: 1-866-766-7489 and request
