Horizontal Installation in an Attic
or Crawlspace
The non-condensing furnace may be installed in an
attic or crawl space in the horizontal position by placing
the furnace on its left or right side (as viewed from the
front in the vertical position). The horizontal furnace
installation in an attic should be on a service platform
large enough to allow for proper clearances on all sides
and service access to the front of the furnace. See the
“Locations and Clearances,” p. 10
. Line contact is only
permissible between lines formed by intersections of
the top and two sides of the furnace casing and
building joists, studs, or framing.
The furnace may be placed horizontally in a crawl
space on a pad or other noncombustible material.
Place blocks underneath to support the furnace and
raise the unit for sufficient protection from moisture.
The furnace may be installed hanging in a hanging
position using straps. The furnace should be supported
at both ends and have an additional support in the
center of the furnace in back.
WHEN SUSPENDING THE HORIZONTAL
FURNACE, IT SHOULD BE SUSPENDED
BY ATTACHING TO THE CABINET
IN THE PLACES SHOWN.
WHEN SUPPORTING THE
FURNACE FROM BELOW,
SUPPORT FRONT TO
BACK (AS SHOWN)
OR SIDE TO SIDE.
