Installation
This appliance must be installed in accordance
with the Manufactured Home Construction and
Safety Standard, (Title 24, CFR; Part 3280) and
ANSI A119.5/NFPA 501D. In addition, install in
accordance with the following instructions, the
instructions supplied with any venting, local codes,
utility company requirements for the installation of
water heaters in manufactured homes (mobile
homes), and the latest edition of the National Fuel
Gas Code, ANSI Z221.3/NFPA 50.
Locate the heater in an enclosure separating the
unit from the internal atmosphere of the
manufactured home or trailer. All combustion air
must be obtained from the outside atmosphere,
and the flue gases must be discharged directly
outdoors through a gas vent. There must be no
opening from the interior of the home or trailer into
the water heater enclosure.
Indoor Installation
Follow indoor installation instructions as set out in
an earlier section of this manual, except that
combustion air must not be taken from the inside
of the home or trailer.
Initiating the Appliance
For your safety, read before operating.
WARNING: If you do not follow these instructions
exactly, a fire or explosion may result causing
property damage, personal injury or loss of life.
a)
This appliance does not have a pilot. It is
equipped with an electronic ignition device,
which automatically lights the burner. Do not
try to light the burner by hand.
b)
Before operating, check for gas accumulation
in the area around the appliance. Pay special
attention near the floor, because gas is often
heavier than air, and it may accumulate near
the floor.
c)
Do not attempt to open the manual gas shutoff
valve with anything but by hand. Never use
tools. If the valve will not open by hand, do not
try to repair it. Instead, call a qualified service
technician. Force or attempted repair may
result in a gas leak, fire or explosion.
d)
Do not use this appliance if any part has been
under water. Immediately call a qualified
service technician to inspect the appliance and
to replace any part that may have been
damaged by being under water.
