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

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.

Burner Flames

Inspect the burner

flames through the

viewport and compare

them to the drawings

in Figure 18. 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.

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. An

anti-scald device is recommended in the hot water supply
line to reduce the risk of scald injury.

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.

The thermostat is adjusted to its lowest temperature
when it is shipped from the factory. Water temperature
can be regulated by moving the temperature dial to the
preferred setting. The preferred starting point is 120°F.
Align the index bar on the thermostat with the desired water
temperature as shown in Figure 19. There is a hot water
scald potential if the thermostat is set too high.
IMPORTANT: Adjusting the thermostat past the 120°F bar
on the temperature dial will increase the risk of scald injury.
Hot water can produce first degree burns within:

120°F (49°C) more than 5 minutes
130°F (54°C) at 20 seconds
140°F (60°C) at 3 seconds
150°F (66°C) at 1-1/2 seconds
160°F (71°C) at less than 1 second

NOTE: During low demand periods when hot water is not
being used, a lower thermostat setting will reduce energy
losses and may satisfy your normal hot water needs. If hot
water use is expected to be more than normal, a higher
thermostat setting may be required to meet the increased
demand. When leaving your home for extended periods
(vacations, etc.) turn the temperature dial to its lowest
setting. This will maintain the water at low temperatures
with minimum energy losses and prevent the tank from
freezing during cold weather.

Burn Hazard

Do not touch vent.
Doing so can result in burns.

WARNING

Water temperature over 125°F can cause
severe burns instantly or death from scalds.
Children, disabled and elderly are at highest
risk of being scalded.
Feel water before bathing or showering.
Temperature limiting valves are available.
