Installer qualicaons: A trained and qualied professional must install the appliance, inspect it, and leak test the water
heater before use. The warranty will be voided due to any improper installaon. The trained and qualied professional

3.1 Installaon Guidelines
• This water heater is suitable for combinaon water
heang and space heang and not suitable for space
heang applicaons only.
• The installaon must conform with local codes or, in
the absence of local codes, with the Naonal Fuel
Gas Code, ANSI Z223.1/NFPA 54, or the Natural Gas
and Propane Installaon Code, CSA B149.1.
• The appliance, when installed, must be electrically
grounded in accordance with local codes or, in the
absence of local codes, with the Naonal Electrical
Code, ANSI/NFPA 70, or the Canadian Electrical Code,
CSA C22.1.
• The appliance and its main gas valve must be
disconnected from the gas supply piping system
during any pressure tesng of that system at test
pressures in excess of 1/2 psi (3.5 kPa) (13.84 in
W.C.). For system tesng at pressures less than or
equal to 1/2 psi (3.5 kPa) (13.84 in W.C.) the
appliance must be isolated from the gas supply
piping by closing its individual manual shuto valve.
• You must follow the installaon instrucons and
those in secon “3.5 Vent the Water Heater” for
adequate combuson air and exhaust.
• If a water heater is installed in a closed water supply
system, such as one having a backow preventer in
the cold water supply line, means shall be provided
to control thermal expansion. Contact the water
supplier or local plumbing inspector on how to
control thermal expansion.
• Should overheang occur or the gas supply fail to
shut o, turn o the manual gas control valve to the
appliance.
(En cas de surchaue ou si l’alimentaon en gaz ne
s’arrête pas, fermez manuellement le robinet d’arrêt
de l’admission de gaz.)
• Combuson air must be free of chemicals, such as
chlorine or bleach, that produce fumes. These fumes
can damage components and reduce the life of your
appliance.
When installing the water heater, follow these guidelines:
DO NOT install the following internal (indoor)
water heaters outdoor: CU160i and CU199i
DO NOT install the following external (outdoor)
water heaters indoor: CU160e and CU199e
DO NOT install the water heater in an area
where water leakage of the unit or connecons
will result in damage to the area adjacent to the
appliance or to lower oors of the structure.
When such locaons cannot be avoided, it is
required that a suitable drain pan, adequately
drained, be installed under the water heater.
The pan must not restrict combuson air ow.
DO NOT install the water heater in an area with
negave air pressure.
DO NOT obstruct the ow of combuson and
venlaon air.
DO NOT use this appliance in an applicaon
such as a pool or spa heater that uses
chemically treated water. This appliance is
suitable for lling large or whirlpool spa tubs
with potable water.
DO NOT use substute parts that are not
authorized for this appliance.
