Section 8: Plumbing System
Close the faucet and turn on the cold water supply. As the tank fills, the air pocket will
develop. Repeat this procedure as often as needed to reduce the frequency of the weeping
P&T valve.
Maintenance
Do not allow the burner to burn with a yellow flame, or continue to operate the water heater
with an improper burner flame.
Periodically, inspect the water heater vent for soot. Soot is a sign of incomplete combustion
and must be corrected before operating the water heater. This is your visual warning that the
water heater is operating in an unsafe manner. If soot is present, immediately shut the unit
down and contact your dealer or a qualified service agency.
Periodically inspect the vent for obstructions. Do not terminate the vent on your water
heater inside of add-on rooms, screen porches or patios. Doing so will result in products of
combustion being vented into the rooms or occupied areas.
Draining and winterization:
If the recreation vehicle is to be stored over the winter months, the water heater must be
drained to prevent damage from freezing. Damage to the water heater caused by freezing
is not warrantable. It is recommended the water heater be drained and bypassed during
the winterization process,
particularly if introducing RV antifreeze into the plumbing
system
.
Never drain the water heater when it is HOT or UNDER PRESSURE.
To drain the water heater:
1.
Turn off electrical power to the water heater either at the switch from the electrical
element of at the breaker.
2.
Shut off the propane supply to the water heater.
3.
Turn off the pressure pump on the water system.
4. Open both hot and cold water faucets.
5. Remove the anode rod from the tank.
For detailed information, see the Winterizing The Plumbing System and Water Heater Bypass
sections of this manual.
Do not place a valve between the pressure and temperature (P&T) valve and
the tank. Do not remove or plug the relief valve under any circumstances.

of your recreational vehicle.
1.

5. Turn ON the hot and cold faucet knobs, and adjust the water temperature as desired.
6. To activate the handheld shower turn ON the sprayer head attachment (some models).
To turn off the water, always
close the hot/cold control (faucet) knobs. The lever on the
shower head will not completely stop the flow of water; this is intentional to allow for
