WARNING: Due to high tem-
peratures, never install the furnace:
• in an inside wall
• in a recreation vehicle
• in a window recessed in a thick
wall (creating an alcove)
• in an alcove
• behind a door or where an open
door would block normal air flow
• as a fireplace insert
• in high traffic areas
• near furniture or draperies
• in windy or drafty areas
CAUTION: If you install the
furnace in a home garage, locate
furnace where moving vehicle will
not hit it.
For convenience and efficiency, install furnace:
• where there is easy access for operation,
inspection, and service
• in a central location, near an electrical
outlet
• where there is adequate clearance around
vents outside
Before installing furnace, inspect the wall,
floor, and outside areas. Make sure there are
no pipes, wiring, or anything else that would
interfere with furnace installation. If you are
installing thermostat in a wall, make sure
there are no pipes or wiring in the hollow
wall above the furnace. The thermostat wires
will pass through this wall from the attic.

nace into wall is included with the furnace.
No venting material is needed. You must
furnish tools and all gas piping from the gas
source to the furnace inlet.

LOCATING FURNACE
This furnace is designed to be mounted in a
wall that is 4 to 18 inches thick. You can also
mount furnace in a window.

tilate to the outdoors.

mum clearances shown in Figure

ances from floor, ceiling, and
joining wall.
WARNING: Turn off electrical
circuits that pass through the wall
where you are going to install the
furnace.
