Pressure & temperature relief valve
When cold water is heated in the water heater
tank, the water pressure will rise. For this
reason, a pressure and temperature (P&T)
relief valve is required for safety in all water
heaters. It is normal for the P&T relief valve to
release a small quantity of water during the
heating cycle and does not indicate a
defective P&T relief valve. One way to reduce
the frequency of the water weeping or
dripping from the P&T relief valve is to
maintain an air pocket at the top of the water
heater. This air pocket will form in the tank by
design; however, it will be reduced over time
by the everyday use of your water heater
(refer to the OEM manual); If the weeping
persists, consult your dealer or a service
agency authorized by the water heater
manufacturer.
Operating instructions
STOP! Read the safety and operating
information provided in the OEM operator’s
manual before attempting to activate the
water heater. Make sure the water heater is
filled with water before use; momentary
operation of the water heater without water in
it can be detrimental.
Draining and winterization
If the RV is to be stored over the winter
months, the water heater must be drained to
prevent damage from freezing. It is
recommended the water heater be drained
during the winterization process particularly if
introducing RV antifreeze into the plumbing
system.
Water heater switch (optional)
The "propane GAS" water heater switch
enables propane operation of the water
heater.

A handheld shower assembly with both hot
and cold water is available for washing or
rinsing outside the RV. Be sure the water
heater is ON and had sufficient time to heat
the water.
Open the door with the key and allow it to
hinge down.
1. If dry camping, be
sure the 12-volt
water pump is ON.
2. Remove the hand
held showerhead
and hose from its
holder and turn ON

valve.
3. Open the faucet
knobs and adjust
them to the desired
temperature.
To cease operation, close the faucet knobs
and the showerhead valve. After the water
has been allowed to drain from the
showerhead, replace it in the outside shower
compartment. Any remaining water in the
shower hose will drip or run out of the vacuum
breaker; this is not a leak but performs as
intended. Water will drain out along outer
edge of the ABS plastic box.
The showerhead can be removed to drain the
hose faster. If you choose to remove the
showerhead to drain the hose, reassemble it
for storage. Coil the hose and arrange it with
the showerhead inside the faucet assembly.
Make sure that the hose is not being pinched
and the showerhead is not being damaged
when the door is closed. For sanitary reasons,
keep the exterior shower compartment door
closed when not in use.

AUCETS
The faucets operate much the same way as
the faucets in your home. Make sure there is
sufficient water available and, if dry camping,
the 12-volt water pump is turned ON before
operating. To open the faucets, turn the hot
and cold knobs ON and adjust the
If you smell propane gas then STOP! and
follow the procedures listed in Sec. 3
Propane System before attempting to
operate the water heater.
