CAMPING & OPERATING

Wash the filter in warm water and mild
detergent. Rinse thoroughly and then
allow the filter to completely dry before
reinstalling. Do not operate the A/C
system without the air filter in place.
•
The roof A/C is installed using a foam
base gasket. Mounting bolts are used to
secure this gasket, and can be found
beneath the inside roof mount. (In some
model units the mounting bolts are located
under the roof mount and behind a metal
faceplate.) Depending on the model type,
there may be two or four bolts. Road
vibration can cause these mounting bolts
to loosen over time. Twice annually check
and torque the mounting bolts and
compress the foam base gasket to one-
half inch.
DO NOT over tighten these bolts as it may
damage the foam base gasket. The foam
base gasket is a wearable part that
eventually will need to be replaced as
maintenance.

URNACE
The RV furnace installed in the RV is
controlled by the thermostat. The furnace
requires both 12-volt power and propane gas
for full operation. Make sure you have
sufficient power available before operating
your furnace. If you have any questions
contact your dealer or Entegra Customer
Service.
Always follow the OEM supplied operating
instructions. Do not deviate from these step-
by-step procedures. Before operating the
furnace, check the location of the furnace
vent to make sure it will not be blocked by the
opening of any door on the RV, and never
operate the furnace with the vent covered.
If considering add-on rooms, porch or patio,
attention must be given to the venting of your
furnace. For your safety, do not terminate the
furnace vent inside any add-on rooms, screen
porch or onto patios. Doing so will result in
products of combustion being vented into the
room or occupied areas.
Maintenance
Periodically inspect the furnace venting.
Venting must be free of obstructions, void of
soot and properly terminated to the
atmosphere. Soot is formed whenever
combustion is incomplete. This is your visual
warning that the furnace is operating in an
unsafe manner. If soot is present, immediately
shut the furnace down and contact your
dealer for repair assistance.
Periodically observe the main burner flame to
assure it is burning with a hard blue flame
with well defined burner ports. If flame
appears yellow or the burner has a lazy
flame, shut the furnace down and contact
your dealer for repair assistance.
Keep the furnace clean. More frequent
cleaning may be required due to excessive
lint from carpeting, bedding material, etc. It is
imperative that control compartments, burners
and circulating air passageways of the
appliance be kept clean.
A qualified RV technician should perform all
furnace maintenance at least once a year
(more often depending on furnace usage). Do
not attempt to repair the furnace yourself.
It is imperative that the products of
combustion be properly vented to
atmosphere and that all combustion air
supplied to the burner be drawn from
outside atmosphere.
Do not operate the furnace while the RV is
in motion or being towed.
Do not install screens over the vent for any
reason. Screens will become restricted and
cause unsafe furnace operation. For your
safety, only OEM factory authorized parts
are to be used on your furnace.
