Vent Installation

The vent installation must comply with all local codes and
ordinances. If in doubt, consult your local codes or inspector.
The furnace vent must be directed to the outdoors so that
harmful combustion gases will not collect inside the building.
This furnace must not be connected to a chimney flue
serving a separate solid-fuel burning appliance.
This product is design certified to ANSI Z21.86. It must be
installed with a U.L. tested and listed type "B" approved vent
and type "B/W" approved vent Figure 8 Older style terra-
cotta, transite pipe, clay, concrete or masonry type vent pipe
cannot be used with this appliance. These types of vent
pipe will not heat fast enough to establish a draft, which
will result in improper venting of combustion products.
