APPLIANCES & INTERIOR FEATURES
burner does not light on first try, the system
will stop trying to light burner and go to
lockout mode.
7. If lockout happens before main burner lights,
turn switch OFF, wait five seconds and turn
switch back on. This will restart the ignition
cycle. The first start-up of the water heater
after it has not been used for a long time may
require several ignition cycles before all the
air is purged from the gas lines and gas
begins to flow.
If the burner will not come on, check the fol-
lowing items before calling for service.
1. Is the switch turned on?
2. Dos the LP tank have gas in it or is main
tank valve turned on?
3. Is the ECO Reset button tripped? (See
Atwood Water Heater Operation Man-
ual
in your Owners InfoCase.)
To Turn Water Heater Off
1. Turn switch on monitor panel to Off posi-
tion.
2. Turn electric water heater switch off.
3. Turn off LP gas supply (if not to be used for
extended period).
4. Drain water heater tank if the coach is to be
stored or water heater will be Off during
freezing temperatures. (See Draining and
Storage Instructions in
Atwood Water Heater
Operation Manual
in your Owners InfoCase.
Pressure-Temperature Relief Valve
On occasion, water may be seen seeping from
the water heater pressure temperature relief
valve. This is no cause for repair or replacement
of the valve.
Normally there is an air gap at the top of the
water heater tank which acts as a pressure buffer.
In time, however, heated water may expand and
fill this air gap, causing a slight increase in water
pressure. This may cause the P-T valve to “weep”
until the air gap is manually replaced.
OPERATE THIS VALVE ONLY WHEN
THE WATER HEATER AND COOLING SYS-
TEM ARE COLD!
To Replace the Air Gap:
1. Turn off the water heater switch and incom-
ing water supply (city water and/or demand
pump).
2. Open a faucet in the motor home to relieve
water pressure.
3. Pull the handle of the P-T valve straight out
and allow water to flow until it stops.
4. Let the handle of the P-T valve snap shut.
5. Close the faucet and turn on the water supply
before switching the water heater on.
Manually operate the pressure temperature re-
lief valve at least once a year.
WATER HEATER BY-PASS VALVE
Your coach may be equipped with a water
heater by-pass valve for easier winterization of
water lines using RV antifreeze. The valve is lo-
cated inside the coach near the water heater. See
pg. 7-8 for the exact location in your coach.
Line up the arrow on the handle with the ap-
propriate label on the valve plate to either by-pass
or flow through the water heater.
