Section 8: Plumbing System

Water Heater

Your RV is equipped with a tank (storage) water heater.
Hydrogen gas may result if you have not used the water heater for two
weeks or more. HYDROGEN GAS IS EXTREMELY FLAMMA-
BLE. To reduce the risk of injury under these conditions, open the hot
water faucet for several minutes at the kitchen sink before you use any
electrical appliance connected to the hot water system. If hydrogen is
present, you may hear what sounds like air escaping through the pipe as
the water begins to flow. Hydrogen gas may be present even after water
has been drained from the water heater tank. Open the faucet at the sink
and allow the system to vent for five to ten minutes. Do not smoke or
have any open flame near the open faucet while venting. On DSI water
heater models, make sure the switch is OFF.
Do not alter the operation or change the design/construction of your wa-
ter heater. For your safety, only factory authorized parts should be used
on your water heater. Accessories marketed for recreation vehicles, such
as an "add-on" electric heating elements, are not recommended by the
manufacturer. Such items are not approved to be installed and could cre-
ate an unsafe condition and will void all warranties.
If you smell propane gas then STOP! and follow the procedures listed
in the Propane System section before attempting to operate the water
heater.
Tank (Storage) Water Heater
The water heater manufacturer has preset the sensing limit to maintain the water temperature
when the water heater is activated. Read the safety and operating information in the manu-
facturer's user guide before attempting to activate the water heater.
Gas/Electric DSI Tank (Storage) Water Heater System
Make sure the water heater is filled with water before use as even momentary operation of
the water heater without water in it may result in damage to the tank and/or controls. Always
open both the hot and cold water faucets when filling the fresh water tank to allow air pock-
ets to be forced out of the water heater. The thermostat on your water heater is not adjustable
and is designed to maintain a water temperature of 130°F (54°C).
The water heater does not have a pilot. It is equipped with an ignition device which auto-
matically lights the burner. Do not try to light the burner by hand.
Operating instructions

ignition cycle will have a 15 second purge before spark cycle if the system is a three
try system.
