Air Conditioner, Continued
Air conditioner gasket
A foam gasket forms the weatherproof seal between the roof
material and the sub-frame of the air conditioner. During nor-
mal operation the air conditioner gasket is subjected to high
wind pressure and motor vibration.
Inspect the gasket seal (at least) annually. Check for leaks and
re-tighten the mounting bolts if needed. To prevent damage to
the gasket, be careful NOT to over-tighten the bolts.
The air conditioner gasket will eventually wear out and need
replacement. To gain access to the bolts, remove the filtered
panel cover on central air systems or the entire air box on
non-central air conditioners.
Furnace
The RV furnace installed in the RV is controlled by a thermostat.
The furnace requires both 12-volt power and propane gas for
full operation. Make sure you have sucient power available
before operating your furnace.
• ALWAYS have your furnace maintenance completed by
a qualified technician (at least once a year, more often
depending on furnace use).
• NEVER attempt to repair the furnace yourself.
If you have any questions, Contact your dealer or
Grand Design Customer Service.
Fireplace (If So Equipped)
Refer to the manufacturer owner's manual for operation,
service and maintenance information.
If you have further questions, please contact your dealer.
The furnace should be
inspected periodically
(monthly during the heating
season) for the presence
of soot on the vent.
Soot is formed whenever
combustion is incomplete.
This is a visual warning that
the furnace is operating in
an unsafe manner.
If soot is observed on the
vent, IMMEDIATELY shut the
furnace OFF and contact
a qualified service agency.
Operating the furnace
under this condition could
lead to serious property
damage, personal injury or
loss of life.
To ensure your personal
safety, DO NOT obstruct
or alter the furnace in any
manner. 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.
DO NOT operate the furnace
when the slide rooms are
retracted in the closed
position.
