JAYCO TOWABLE
Do not replace any component part with an accessory part that is not
authorized by the water heater manufacturer, such as an "add-on" electric
heating element. Such items are not approved to be installed and could
create an unsafe condition and will void all warranties.
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; 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.
Operating instructions
If you smell propane gas then STOP! and follow the procedures listed in the
Propane System section of this manual before attempting to operate the
water heater.
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.
Draining and winterization
If the RV is to be stored over the winter months, the water heater must be drained
to prevent damage from freezing. It is recommended the water heater be drained
and bypassed during the winterization process particularly if introducing RV
antifreeze into the plumbing system.
Water heater bypass
Use the factory installed water heater bypass, available in most floor plans, to
avoid filling the entire water heater with RV antifreeze.
To bypass the water heater close valves A and B, and open the mixer valve (valve
C). For normal camping usage of the water heater, reverse these instructions.
Water heater switch (if so equipped)
The "propane GAS" water heater switch enables propane operation of the water
heater. The "ELECTRIC" water heater switch enables electric operation of the
water heater
