Your motor home has been equipped with a
gas/electric DSI (direct spark ignite) water
heater. The following is an overview of the
water heater operation. For details on the
operation and safety information of the water
heater, refer to the manufacturer’s user’s
guide included in the Owner’s Portfolio
Read the safety and operating information
provided in the manufacturer’s user guide
before attempting to activate the water heater.
Make sure the water heater is filled with water
before use; 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 pockets to be forced out of the water
heater.
The DSI water heater is designed to heat
water quickly and efficiently. The water heater
manufacturer has preset the sensing limit to
maintain the water temperature when the
water heater is activated. The thermostat on
your water heater is not adjustable. It is a
temperature sensing limit 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
automatically lights the burner. Do not try to
light the burner by hand.
Operating instructions
1. Turn OFF all electric power to the water
heater.
2. Turn OFF the propane supply.
3. Wait five minutes for the propane to clear
the area. If you smell propane STOP!
Follow the safety instructions listed in the
manufacturer’s owners manual. If you do
not smell propane, go to the next step.
4. Turn ON the propane supply.
5. Turn ON electrical power to the water
heater.
6.
Turn the switch to the “ON” position. If the
burner does not light, the system will
automatically attempt two more tries for
ignition before lock-out occurs. NOTE:
E
ach ignition cycle will have a 15 second
purge before spark cycle if system is a
three try system.
7. If lock-out occurs before the main burner
lights, turn the water heater control switch
to OFF, wait five seconds and turn the
switch to the ON position. This will restart
the ignition cycle.
Hydrogen gas may result if you have not
used the water heater for two weeks or
more.
HYDROGEN GAS IS EXTREMELY
FLAMMABLE.
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.
If you smell propane gas then
STOP!
and
follow the procedures listed in
Sec. 6
Propane System
before attempting to
operate the water heater.
Do not alter the operation or change the
design/construction of your water heater.
Accessories marketed for recreation
vehicles are not recommended by the
manufacturer. For your safety, only factory
authorized parts should be used on our
water heater.
