CONVERSIONS MUST BE PERFORMED BY A QUALIFIED INSTALLER OR SERVICE

This furnace is shipped from the factory configured for natural
gas at standard altitude. Propane gas installations require
an orifice change to compensate for the energy content
difference between natural and propane gas.
High altitude installations may require both a pressure switch
and an orifice change. These changes are necessary to
compensate for the natural reduction in the density of both
the gas fuel and the combustion air at higher altitude.
Refer to the Accessories Charts in this manual or product
Specification Sheet for a tabular listing of appropriate
manufacturer's kits for propane gas and/or high altitude
installations. The indicated kits must be used to insure
safe and proper furnace operation. All conversions must be
performed by a qualified installer, or service agency.

A condensing gas furnace achieves its high level of efficiency
by extracting almost all of the heat from the products of
combustion and cooling them to the point where condensation
takes place. Because of the relatively low flue gas temperature
and water condensation requirements, PVC pipe is used as
venting material.
This furnace must not be connected to Type B, BW, or L vent
or vent connector, and must not be vented into any portion
of a factory built or masonry chimney except when used as
a pathway for PVC as described later in this section. Never
common vent this appliance with another appliance or use a
vent which is used by a solid fuel appliance.
It is the responsibility of the installer to follow the manufacturers'
recommendations and to verify that all vent/flue piping and
connectors are compatible with furnace flue products.
Additionally, it is the responsibility of the installer to ensure

Precautions should be taken to prevent condensate from
freezing inside the vent/flue pipe and/or at the vent/flue pipe
termination. It is our recommendation that all vent/flue piping
exposed to temperatures below 35°F for extended periods
of time should be insulated with 1/2" thick closed cell foam.
Also all vent/flue piping exposed outdoors in excess of the
terminations shown in this manual (or in unheated areas)
should be insulated with 1/2" thick closed cell foam. Inspect
piping for leaks prior to installing insulation.
The following bullets and diagram describe the restrictions
concerning the appropriate location of vent/flue pipe and
combustion air intake pipe (when applicable) terminations.
Refer to or the installation instructions for specific details on
termination construction.
• All terminations must be located at least 12 inches above
ground level or the anticipated snow level.
• Vent terminations must terminate at least 3 feet above
any forced air inlet located within 10 feet.
• NOTE: This provision does not apply to the combustion
air intake termination of a direct vent application.
• The vent termination of a non-direct vent application
must terminate at least 4 feet below, 4 feet horizontally
from, or 1 foot above any door, window, or gravity air
inlet into any building.
• The vent termination of a direct vent application must
terminate at least 12 inches from any opening through
which flue gases may enter a building (door, window,
or gravity air inlet).
• The vent termination of vent pipe run vertically through
a roof must terminate at least 12 inches above the roof
line (or the anticipated snow level) and be at least 12
inches from any vertical wall (including any anticipated
snow build up).
• A vent termination shall not terminate over public
walkways or over an area where condensate or
vapor could create a nuisance or hazard or could be
detrimental to the operation of regulators, relief valves,
or other equipment.
• The combustion air intake termination of a direct vent
application should not terminate in an area which is
frequently dusty or dirty.
NOTE: In Canada, the B149 Fuel Gas Code takes precedence
over the preceding termination restrictions.
