Water Heater
The water heater manufacturer has preset the sensing limit to maintain the water temperature
when the water heater is activated.
Operating Instructions
Read the safety and operating information provided in the manufacturer’s manual before
attempting to activate the water heater.
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 heating element and/or
controls.
Double check the bypass valves
, make sure they are set properly.
Always open both the hot and cold water faucets when filling the fresh water tank to allow
air pockets to be forced out of the water heater.
Water heater switch (if so equipped)
The “propane GAS” switch enables propane opera-
tion of the water heater, and the “ELECTRIC” switch
enables electric operation. Switches are typically lo-
cated on the monitor panel. For detailed information,
refer to the
Monitor Panel
section.
Water heater-pilot light (if so equipped)
This water heater is gas only with a pilot ignition. The
water heater controls are typically located in an out-
side compartment, and is ignited manually from the
outside of the vehicle. Hot water will be available in
approximately 30 minutes.
Refer to the water heater manufacturer’s manual for detailed lighting instructions.

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
create 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.
