Section 8: Plumbing System

This “weeping” or dripping will continue until the pressure is reduced to below 150 pounds,
and the valve closes. This condition is normal and does not indicate a defective relief valve.

One way to reduce the frequency of this occurrence is to maintain an air pocket at the top
of the water heater tank. 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. To replenish this air pocket:

Turn off the water heater.

Turn off the cold water supply line.

Open a faucet in the RV.

Pull out the handle of the pressure relief (P&T) valve and allow water to flow from the

valve until it stops.

Release the handle on the P&T valve - it should snap closed.

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 pres-

ent, 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 combus-
tion 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 sys-

tem. Never drain the water heater when it is HOT or UNDER PRESSURE.

To drain the water heater:

Turn off electrical power to the water heater either at the switch from the electrical ele

ment of at the breaker.

Shut off the propane supply to the water heater.

Turn off the water pump.

Open both hot and cold water faucets.

Remove the anode rod from the tank.

Winterizing the Plumbing System.

TRUMA® Tankless Water Heater

Your recreation vehicle is equipped with a Truma® tankless water heater. The tankless water
heater has no pilot light and supplies an unlimited supply of hot water on demand. It does not

require an anode rod to prevent corrosion, and is not affected by high altitudes. The output

temperature of the water depends on the temperature of the inlet water AND the amount of
hot water that is drawn. If the inlet water temperature is over 65°F, the tankless water heater

will generate water in the range of 113°F to 120°F depending on the water flow selected by

the user.

NOTE: A pressure regulator is recommended to be used on your pressurized

water line to maintain water pressure around 45 PSI.
