Periodically check the service compartment and screen in the door on the
outside of the motorhome to ensure no foreign material has accumulated which
will prevent the flow of combustion and ventilating air.
The water heater bypass is a valve located on the back of the water heater.
By turning the valve to
BYPASS
position, water diverts away from entering
the water heater. The water heater should be in the
BYPASS
position when
winterizing. Bypassing the water heater will keep antifreeze out of the water
heater, if antifreeze is used for winterization.
For water heater operation turn the valve so that the handle points to
NOR-
MAL FLOW
.
The water heater is equipped with a Pressure-Temperature relief
valve. The water heater may discharge at the Pressure-Temperature
relief valve during the heating cycle, due to thermal expansion of
water. The Pressure-Temperature relief valve is designed to open
if the water temperature within the heater reaches 210° F (98.8°
C), or if the water heater pressure reaches 150 psi. This can be
related to the fact the motorhome utilizes a closed system. A dis-
charge is a normal occurrence and is not necessarily a faulty
valve. The water heater has an internal air pocket to reduce the
possibility of dripping or weeping. Eventually, the expansion of
the water will absorb the air pocket. When this occurs, utilize the
following procedures to replace the air.
CAUTION: Ensure the water heater tank is cool
prior to checking the valve.
1. Turn OFF the water heater.
2. Shut OFF the incoming water supply.
3. Open the closest hot water line of the motorhome.
4. Pull the handle of the relief valve until the flow of water stops.
5. Allow the relief valve to snap shut, close the hot faucet and turn on the
water supply.
6. Turn ON the water heater.
The air pocket is re-established; the process need not repeated until the
next discharge of water. If the discharge does not stop, contact a qualified
service center to evaluate the valve and make any required repairs.
