7. WALL MOUNTING INFORMATION
1. Two holes for the supply and return air
openings must be cut through the wall as
detailed in Figure 4.
2. On wood-frame walls, the wall construction
must be strong and rigid enough to carry the
weight of the unit without transmitting any unit
vibration.
3. Concrete block walls must be thoroughly
inspected to insure that they are capable of
carrying the weight of the installed unit.
8. MOUNTING THE UNIT
1. These units are secured by wall mounting
brackets which secure the unit to the outside
wall surface at both sides.
2. For all models the supply air duct flange and the
first 3 feet of supply air duct require a minimum
of 1-inch clearance to combustible material. The
WF models are suitable for 0 inch clearance on
the installation mounting wall, but require 1-inch
clearance to the top if combustible material
overhang projects above the unit. See Figure 3.
If a combustible wall, use a minimum of Figure 1
“A” dimension plus 2 inches and “B” dimension
plus 2 inches. See Figures 4 and 5 for details.
3. Locate and mark lag bolt locations.
4. Hook top rain flashing under back bend of top.
Top rain flashing is shipped secured to the right
side of the back.
5. Position unit in opening and secure with 5/16
lag bolts; use 7/8 inch diameter flat washers on
the lag bolts. Use lag bolts long enough to
support the unit’s weight when mounted to the
structure. This length may be dependant on the
type of construction.
6. Secure rain flashing to wall and caulk across
entire length of top. See Figure 3.
7 . On side-by-side installations, maintain a
minimum of 20 inches clearance on right side
to allow access to control panel and burner
compartment. Additional clearance may be
required to meet local or national codes.
WARNING
Failure to provide the one inch clearance
between the supply duct and a combustible
surface for the first three feet of duct can
result in fire causing damage, injury or death.
