Water Heater

The water heater manufacturer has preset the sensing limit to maintain the water temperature
when the water heater is activated.
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.
Do not alter the operation or change the design/construction of your
water 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.
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 operation of the water heater, and the
"ELECTRIC" switch enables electric operation. Switches are typically located on the
monitor panel. For detailed information, refer to the Monitor Panel section.
