Pressure-Temperature Relief Valve; Propane Gas Furnace - Winnebago Chalet Manual

D-Series Class-A
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.
Water Heater Exterior Service Access
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.
CAUTION
Operate this valve only when the water
heater and engine cooling system are
cold!
To Replace the Air Gap:
1. Turn off the water heater switch and incoming
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.
APPLIANCES & SYSTEMS
Lift handle straight out to open P-T
valve when water heater is cold *
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
relief valve at least once a year.
*If your water heater is equipped with the Motor
Aid system, it uses an extension from the engine
cooling system to heat water in the water heater
while driving. The engine cooling system must
also be cold before opening the pressure-
temperature relief valve. See "Motor Aid Water
Heater" for more information.
