The heater must be supplied with sufficient quantities
of non-contaminated air to support proper combustion
and equipment ventilation. Combustion air can be sup-
plied via conventional means where combustion air is
drawn from the area immediately surrounding the heat-
er, or via direct vent, where combustion air is drawn
directly from outside. All installations must comply with
the requirements of the NFGC (U.S.) and B149 (Cana -
da), and all local codes.
Reversing Air Filter
Follow these instructions to change the air duct con-
nection from the left-hand side (standard) to the right-
hand side:
1. Remove the four screws and the dust cover from
the right-hand side of the heater.
2. Remove the four screws and the air filter bracket
from the left-hand side of the heater.
3. Reverse the components and reattach in the
new location, making sure that the air filter lock -
ing bracket is on the bottom. (The air filter locking
bracket is reversible.)
Direct-Ducted Combustion Air
In certain applications it may be desirable to duct the
combustion air directly to the heater. This should be
done with PVC, CPVC or single-wall galvanized duct-
ing. The duct will attach directly to the collar on the air
filter housing located on the side of the heater. The
ducting is attached to the air filter housing collar using
three or four sheet metal screws (not supplied) equally
distributed around the circumference of the duct.
A
CAUTION: Combustion air must not be
contaminated by corrosive chemical fumes
which can damage the heater and void the
warranty. (See the Appendix.)
NOTE: It is recommended that the intake vent be
insulated to minimize sweating.
NOTE: Use of the heater in construction areas
where fine particulate matter, such as concrete or
dry-wall dust, is present may result in damage to
the heater that is not covered by the warranty. If
operated in a construction environment, a clean
source of combustion air must be provided directly
to the heater.
