SECTION 8 – PLUMBING SYSTEMS
If you smell propane gas then STOP! and follow the procedures listed in the
Propane System Section before attempting to operate the water heater.
Your motor home is equipped with either a tank or tankless water heater. The
following is an overview of both systems. For detailed operating instructions, refer
to the manufacturer's owner's manual supplied in your Warranty packet.
Odor from the hot water system
Many water supplies contain sufficient amounts of sulfur to produce an odor, often
called "sulfur water." Sulfur water can be caused by a chemical action or by
bacteria. Generally, sulfur water is not harmful, only unpleasant to smell. Refer to
the water heater manufacturer's owner's manual for details on eliminating the odor
from sulfur water. Odor from sulfur water is not a service problem.
Water heater bypass (If So Equipped)
Your motor home may be equipped with a water heater bypass. This three-valve
system is located at either the water heater, or on the system panel depending on
your model. The water heater bypass valves must be in the NORMAL position
(open the hot and cold valves, close the mixer – or middle – valve) to use the
water heater (and when sanitizing). If winterizing the motor home plumbing
system, position the three valves to the BYPASS position (close the hot and cold
valves, open the mixer - or middle - valve).
GAS/ELECTRIC DSI WATER HEATER (If So Equipped)
Your motor home may be equipped with a gas/electric DSI (direct spark ignite)
water heater. The following is an overview of the water heater operation. For
detailed operating and safety information, refer to the manufacturer's user's guide
included in the Owner's Warranty packet.
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.
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.
