Furnace installation on combustible flooring is
permitted with combustible floor base available
from manufacturer. Read installation instructions
packaged with combustible floor base to correctly
install. See Figure 8.
TYPICAL ATTIC INSTALLATION
FIGURE 7
When using single wall vent pipe in horizon
tal
installations,
horizontal
furnaces
with
14.50" high casings must be raised 1" to
have 6” clearance to combustible material.
See Figure 7.
c.
Install a platform under furnace that extends
a minimum 30" in front of furnace. This pro
vides a work area and keeps insulating ma
terials away from combustion air openings.
Secure platform to ioists.
WARNINOs
When a furnace Is installed
In an attic or other Insulated space, keep
all insulating materials at least 12" away
from furnace and all burner combustion
air openings. Failure to do so could cause
nausea, asphyxiation or fire, resulting In
damage. Injury, or death.
d.
Crawl Space Installation.
Furnace can be hung from floor joists or in
stalled on suitable blocks or pad. Pad or
blocks should provide enough height to re
duce potential for water damage. See Sec
tion 7.
3.
Downflow Installation.
You must convert furnace from as-shipped con
figuration for downflow furnace installation. See
Section 5.
DOWNFLOW FLOOR OPENING
FIGURE 8
See Figure 9 for installation diagram on com
bustible floor.
4.
Service Clearance.
Allow minimum front clearance of 30 inches for service.
See Figure 6 or inside of front door for minimum service
clearance.
SECTION 7 — SUSPENDING FURNACE.
Some installations will require that furnace be suspended
from rafters or floor joists.
A common way to do this using threaded rods is shown in
Figure 10. Consider this means when people may walk un
derneath furnace. Figure 11 shows another common suspen
sion means using pipe strap. Other means that provide ad
equate support may be used.
When furnace is not suspended in a crawl space, elevate
furnace off ground to avoid water damage and allow for air
conditioning coil drain.
Downflow position is approved for installation on
non-combustible flooring. Typical downflow fur
nace installations are an alcove, attic, closet,
basement, garage, or utility room. See Figure 6
or furnace clearance plate for minimum clear
ances to combustible materials.
