L.P.G. (Bottled Propane) Models
Liquefi 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
refi lled, all appliances must be re-lit according to their
manufacturer's instructions.

Checking the Draft

Do not touch vent.
Doing so can result in burns.
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
Figure 17
draft test. Pass
a match flame
around the relief
Match
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.

Burner Flames

Inspect the burner flames through the viewport and
compare them to the drawings in Figure 18. A properly
operating burner
should produce
Figure 18
a soft blue flame.
Flame Characteristics
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.
