Installing Wall Bracket (Figures 5 and 6)
After finding a location for the furnace, gas supply and vent, the
wall bracket must be positioned and installed. The bracket should
be mounted to the wall studs, if possible, or anchored solidly to the
wall. Use the (2) 10 x 1" (25mm) hex-head screws or (2) plastic
anchors provided. Drill (2) 5/16" (8mm) diameter holes in wall if
plastic anchors are used. Attach the two wall mounting brackets
to the casing back by using (4) 10 x 1/2" (13mm) hex-head screws
provided.

Venting (Figures 7, 8 and 9)
This unit is vented directly out the back using the concentric vent
tube assembly provided. See Figure 2 for vent hole location. This
hole location can be conveniently moved closer to unit exhaust
outlet tube to avoid wall stud interference if necessary. The orange
silicone exhaust elbow would need to be cut to length. Do not
locate vent directly behind the exhaust outlet. Do not use the orange
silicone elbow for extended vent runs where the possibility of
flue condensate exists unless the run is horizontal and the elbow is
sloped downward away from the heater. See Figure 12 for extended
vertical venting.
The vent provided will accommodate walls up to 10" thick and
can be cut shorter for thinner walls if desired by using a hacksaw
or cut-off saw. Be sure to leave the minimum 3/4" of tube length
extending beyond the outside wall plate. Both the inner and outer
tube will be cut to the same length as the inner exhaust tube has an
extension piece which is added during final outside assembly.
