Water Heater - Airstream 1980 Argosy Owner's Manual

Water Heater
The Atwood-Bowen Gas Water Heater is
equipped with an LP gas pressure regulator
contol with a 100% shut-off safety valve which
shuts off the gas supply if the pilot flame is
extinguished or the water temperature
becomes excessively hot. It is lighted and
serviced from the outside through a
hinged access panel.
Procedure for lighting or relighting:
1. Be sure the water heater is filled with
water. To fill, connect hose to city water
supply or turn on water pump. Turn on
galley or lavatory hot water faucet and
allow water to run unt~l all air is expelled.
2. Turn gas supply l~ne valve, on the lower
exterior of the trailer below the water
heater, to the "ON" position (valve handle
parallel with gas line).
3. Turn Lighting Control dial "A" to "Pilot"
position and hold against stop while
lighting pilot burner. Allow pilot to burn
approximately one half minute before
releasing dial.
4. Turn dial to "ON" position. If pilot does
not remain lit, repeat operation allowing
longer period before releasing dial.
5. Position temperature lever "6" to desired
comfort.
6. To shut down the water heater, turn the
gas cock knob to the "OFF" position.
If the pilot flame does not have a small orange
tip, the pilot is not getting enough gas. The
flame should be about Yi inch in vertical height
when the water in the tank is cold and the
burner is off,
%
to . % inch in horizontal length
when the tank is warm.
A large orange flame indicates excessive gas
supply, which will result In short pilot life and
early replacement. The pilot has been properly
adjusted at the factory and should operate with
a blue, orange tipped flame enveloping the
p~lot thermocouple. The flame is adjusted by
using pilot gas adjustment screw (C). Turning
this screw clockwise reduces the flow of
gas to the pilot (blue flame) and counter-
clockwise, the gas supply will increase
(orange flame).
All fuels depend upon air (oxygen) to give them
proper burning characteristics. A yellow,
smoking flame ind~cates a lack of air and a
noisy hard blue flame indicates too much air.
The air shutter slides back and forth along the
burner tube and is held in place by a small
shutter adjustment screw (D). Loosen the screw
for adjustment. A good method of adjusting the
air shutter is to slide the shutter to the right until
yellow tipping occurs on the main burner flame
(not the pilot) and then slowly slide the shutter
lo the left until all signs of yellow tipping are
gone. When proper adjustment has been
obtained, tighten the screw holding the air
shutter. The outside access door must be kept
locked for proper operation.
NOTE: If you wish to bypass your water heater
in order to cut down on the amount of
antifreeze necessary when winterizing (see
page 35), you may purchase a kit for this
purpose from a Wally Byam Store.
