Furnace/Water Heater Gas Shut-off Valve
Several TMC Class B motorhome models are equipped with
a Truma furnace/water heater combo (see Interior Section).
The main heating unit is equipped with a gas shut-off valve,
which is electrically controlled by a switch that is located on
the main unit. The switch (Fig. 1) shuts off the power to the
safety gas shut-off valve and therefore, the gas supply to the
Combi furnace. Under normal operations, this switch can
be left ON because operating the furnace and water heating
control is done on a separate control panel.
Use this gas valve shut-off whenever maintenance to the unit is
required, or when storing the vehicle for an extended period.
To make sure that the gas supply to the furnace is off, turn the
switch to the OFF position. If the furnace/water heater is not
producing hot water or hot air, check the position of this switch;
it must be in the ON position for the unit to operate properly.
NOTE: This switch does not affect gas supply to oth-
er gas appliances within the motorhome, nor does it
affect the main gas valve switch of the motorhome.
Figure 1
External Propane Hook-up
Only operate external LP gas appliances for their
intended purpose. Follow all safety and operational
instructions associated with the appliance. The risk of
fire, explosion or severe bodily injury exists.
Propane available at this source is at normal and
regulated operating pressure. Never bypass or defeat
the gas regulator installed on the motorhome’s propane
system.
DANGER DANGER
WHEN USING THE OUTDOOR COOKING AREA:
• The vehicle must be level and stabilized.
• Do not violate manufacturers’ instructions on required
clearances for cooking appliances during use.
• Do not store cooking appliances until cool to the touch.
Can lead to a fire and explosion and result in death or
serious injury.
WARNING WARNING
The Auxiliary Propane Gas Hook-up is equipped with a
manual LP gas shut-off valve, located near the quick-
disconnect coupler. Always turn OFF this gas valve
when this LP source is not in use.
As with the main gas valve, ensure this valve is in the
OFF position when traveling.
WARNING WARNING
Ensure that children and pets stay well away from
any gas appliance in use or connected to the external
propane hook-up.
Do not use or operate appliances designed for outdoor
use inside the motorhome.
Potential injuries due to trips, falls, flame and heat
exist whenever an external gas hose, along with a gas
appliance is in use.
CAUTION CAUTION
