WARNING! Installation of this appliance must be made in accordance with
the written instructions provided in this manual. No agent, representative or
employee of Suburban or other person has the authority to change, modify or
waive any provision of the instructions contained in this manual.
CAUTION: If possible, do not install the furnace to where the vent can be covered
or obstructed when any door on the trailer is opened. If this is not possible,
then the travel of the door must be restricted in order to provide a 6" minimum
clearance between the furnace vent and any door whenever the door is open.
NOTE: The exhaust temperature of this furnace could discolor or warp some
materials. You should verify that the material used on the coach door, panel, or
cover will not discolor or warp from the exhaust temperature whenever any door,
panel, or cover is in the open position.
CAUTION: Due to the differences in vinyl siding, this appliance should not be
installed on vinyl siding without first consulting with the manufacturer of the
siding or cutting the siding away from the area around the appliance vent.
CAUTION: In any installation in which the vent of this appliance can be covered
due to the construction of the RV or some special feature of the RV such as slide
out, pop-up, etc. always insure that the appliance cannot be operated by setting
the thermostat to the positive "OFF" position and shutting off all electrical and

so that the negative pressure created by the air circulating (return air) fan cannot
affect the combustion air intake or venting of any other appliance. It is imperative
that the products of combustion be properly vented to the atmosphere and that
all combustion air supplied to burner be drawn from the outside atmosphere.
(See 'Installing Vent Assembly'.)
IMPORTANT: If this furnace is to be connected to a common duct system also
serving a cooling unit, a manual or automatic damper is required to prevent
any cold conditioned air from circulating back into the furnace. Cold air passing
over the furnace combustion chamber during the operation of the cooling unit
can result in the formation of condensation inside the furnace combustion
chamber. This condensation may promote corrosion and premature failure of
the combustion chamber.
NOTE: These furnaces shall be installed so the electrical components are
protected from water.
These furnaces are design certified for Propane/LP gas only. Do not attempt to
convert to natural gas.
