Low Point Drain Valves

Low point drain valves are used to drain the fresh water system
whenever maintenance, sanitizing, or winterizing is required.
The valves are installed in at the lowest point of the water system,
thus providing a complete system evacuation. The valves allow
draining the hot and cold water lines and the fresh water tank.
The low-point drain valves are located along the lower left side
of the motorhome (location varies depending on floor plan
and features).

Furnace/Water Heater Combo

CARBON-MONOXIDE POISONING HAZARD!
Failure to follow instructions could result in severe
personal injury or death due to carbon-monoxide
poisoning if combustion gases enter the RV.
Check that all openings in the outside wall around
the vent (and air intake) pipe(s) are sealed to prevent
combustion gases entering the RV.
Check that furnace vent and air intake are not
obstructed in any way.
Never operate the combination furnace/water heater in
an enclosed or confined space.
This combination
danger of hot surfaces and hot gases. Do not touch the
area around the wall cowl and do not lean any objects
against the wall cowl (furnace exhaust).
Your motorhome is equipped with a factory-installed LP-fired
combination furnace/water heater, designed specifically for
recreational vehicles (also described in the Interior Section of
10
this manual).
The furnace/water heater combination unit has an internal
tank that holds a volume of 2.6 gallons of water. Some
models use a combination of LP gas and electric to rapidly
heat water and provide warm air. Some Class B installations
include a separate wall-mounted controller for the furnace/
water heater, while others may integrate operational functions
within the multiplex system.
Set the desired hot water temperature on the furnace/water
heater controller. The temperature at the hot water faucets
will not exceed this setting.
For complete safety information and operational instructions
on the particular furnace/water heater unit installed in your
motorhome, please refer to the water heater manufacturer's
guide contained in your Owner's Packet or visit the water
heater manufacturer's website. Product information is also
available in the TMC Water System Guide and TMC Class
B Supplement, available from the on-line TMC Owners
Resource document service.
