L.P.G. (Bottled Propane) Models
Lique
fi
ed petroleum gas is over 50% heavier than air
and in the occurrence of a leak in the system, the gas
will settle at
fl
oor level. Basements, crawl spaces, skirted
areas under mobile homes (even when ventilated), closets
and areas below ground level will serve as pockets for
the accumulation of gas. Before lighting an L.P. gas water
heater, smell all around the appliance at
fl
oor level. If you
smell gas, follow the instructions as given in the warning on
the front page.
When your L.P. tank runs out of fuel, turn off the gas at
all gas appliances including pilot lights. After the tank is
re
fi
lled, all appliances must be re-lit according to their
manufacturer’s instructions.
Checking the Draft
After successfully lighting the water heater, allow the unit
to operate for 15 minutes and check the drafthood relief
opening for proper draft. Make sure all other appliances
in the area are operating and all doors are closed when
performing the draft
test. Pass a match
flame around the
relief opening of
the drafthood. A
steady flame drawn
into the opening
indicates proper
draft. If the flame
flutters or is blown
out, combustion
products are
escaping from the relief opening. If this occurs, do not
operate the water heater until proper adjustments or
repairs are made to the vent pipe system and/or air supply
requirements.

Burn Hazard
Do not touch vent.
Doing so can result in burns.
WARNING
Burner Flames
Inspect the burner flames through the viewport and
compare them to the drawings in Figure 21. A properly
operating burner should produce a soft blue flame. Blue
tips with yellow inner cones are satisfactory. The tips of the
flame may have a slight yellow tint. The flame should not be
all yellow or have a sharp blue-orange color. Contaminated
air may cause an orange colored flame. Contact a qualified
person if the flame is not satisfactory.
Water Temperature Stacking
Stacking occurs when a series of short draws of hot water
(3 gallons or less) are taken from the water heater tank.
This causes increased cycling of the burner and can result
in increased water temperatures at the hot water outlet.
This water heater’s temperature control has been designed
to accurately regulate the water temperature. However,
under certain operating conditions, the water temperature
may temporarily exceed the dial setting. Consequently, in
addition to setting the temperature no higher than 120°F,
we recommend the installation of a mixing valve or an
anti-scald device in the hot water supply line or at the point
of use to further reduce the risk of scald injury. These
devices can be obtained from a plumbing service agency or
your retail supplier.
Emergency Shut Down
IMPORTANT:
Should overheating occur or the gas supply
fails to shut off, turn off the water heater’s manual gas
control valve and call a qualified person.
