by a non-qualified installer may void warranty. Failure to comply with state and local codes
pertaining to water heater installations may void also warranty.
American Hometec water heaters are suitable for installation as a single standalone unit or in
installations involving combinations of multiple units (i.e. parallel or series). These guidelines are
for the installation of a single unit. Please contact American Hometec at 1-800-295-8039 for
multiple device connection assistance.
This appliance shall NOT be installed outdoors.
A qualified installer or service technician should inspect and leak test system before use.
The installation must comply with local codes. In the absence of local codes the
National Fuel Gas
Code, ANSI Z223.1/NFPA 54
, or the
Natural Gas and Propane Installation Code, CSA B149.1
shall
prevail.
The appliance must be electrically grounded in accordance with local codes. In the event there are
no local codes, the
National Electrical Code, ANSI/NFPA 70
, or the
Canadian Electrical Code, CSA
C22.1

Maximum inlet gas pressure must not exceed the value specified by the manufacturer and that the
minimum value listed is for purposes of input adjustment.
Disconnect the heater and the heater main gas valve from the gas supply piping system during any
pressure testing. Isolate the heater from the gas supply piping system by closing the inlet manual
shutoff valve. The gas pressure will be between these values 3.5 in W.C. (870 Pa) 10.5 in W.C.
(2610 Pa) for Natural Gas and 8.0 in W.C. (1990 Pa) 13.0 in W.C. (3230 Pa) for Liquid Propane.
The appliance should be located in an area where water leakage of the unit or connections will not
result in damage. Take precaution by properly installing a drain pan under the heater if required
to protect area where leakage would travel.
Do not obstruct the combustion air intake or heater exhaust and ensure air intake is not near an
area that will allow chemical fumes to enter the combustion air system.
Do not use to heat pools or spas (hot tubs) that uses chemically treated water.
If a water heater is installed in a closed water supply system, special precautions are required such
as installation of a backflow preventer and allowance for thermal expansion. Consult an
authorized professional for proper installation requirements.
