condition (“W.H. Pilot” light on). When
water cools, reset by placing switch in “Off”
position for at least 30 seconds, then return
to “On” position.
5. If a lockout condition persists: contact your
dealer, an Atwood Service Station or
Atwood Service Department (Phone: 815-
877-5700).
6. For complete shut-down before servicing:
a) Place Water Heater switch in “Off” posi-
tion.
b) Remove red wire from left-hand terminal
of ECO switch (ECO to valve).
WATER HEATER PRESSURE-TEMPERA-
TURE 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.
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. OPERATE THIS
VALVE ONLY WHEN THE WATER HEAT-
ER AND COOLING SYSTEM ARE COLD!
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
Section 7 for the exact location in your coach.
Line up the arrow on the handle with the ap-
propriate arrow on the valve plate to either by-
pass or flow through the water heater.
The temperature knob or lever is fac-
tory adjusted to its lowest setting. We
recommend the mid-point position
between warm and hot, as noted
above. This will provide for energy
efficient operation and sufficiently
hot water. Setting at a higher position
will produce a higher temperature and
increase the risk of being scalded.
