VENTING

GENERAL INFORMATION

The furnace must be vented in accor-
dance with these instructions, National
Fuel Gas Code, ANSI Z223.1 and/or
the Natural Gas Installation Code, CSA-
B149.1 & .2 and requirements or codes
of the local utility or other authority hav-
ing jurisdiction.
WARNING
DEVICES ATTACHED TO THE FLUE
OR VENT FOR THE PURPOSE OF
REDUCING HEAT LOSS UP THE
CHIMNEY HAVE NOT BEEN TESTED
AND HAVE NOT BEEN INCLUDED IN
THE DESIGN CERTIFICATION OF
THIS FURNACE. WE, THE MANUFAC-
TURER, CANNOT AND WILL NOT BE
RESPONSIBLE FOR INJURY OR
DAMAGE CAUSED BY THE USE OF
SUCH UNTESTED AND/OR UNCER-
TIFIED DEVICES, ACCESSORIES OR
COMPONENTS.

DRAFT INDUCER

WARNING
VENT PIPE ATTACHING HOLES
MUST BE PREDRILLED IN THE
DRAFT INDUCER COLLAR TO PRE-
VENT DAMAGING THE INDUCER.
DRILL 1/8" DIAMETER HOLES
THROUGH THE VENT PIPE AND
COLLAR AND USE #8 SCREWS TO
ATTACH. SEE FIGURE 12. FAILURE
TO FOLLOW THIS WARNING CAN
CAUSE RECIRCULATION OF FLUE
PRODUCTS CAUSING CARBON

FURNACE CATEGORY
INFORMATION
This furnace is shipped as a Category
type induced draft furnace. A Category
furnace operates with a nonpositive
vent pressure and has a vent gas tem-
perature at least 140°F above the dew
point of the vent gases. A Category
type may be a draft hood equipped fur-
nace or have a fan assisted combustion
system (induced draft). The inducer is
used to pull flue products through the
combustion chamber and as they leave
the furnace, most of the energy has
been dissipated. The buoyant effect of
the flue gases provides venting to the
outdoors.
During the off cycle, the inducer is off
and there is very little flow through the
vent, cooling the vent. During the on
cycle there is no dilution airflow, as with
a draft hood type furnace. Although the
vent heats up rapidly without dilution
air, the flue products contain more
water vapor, which results in a higher
dew point temperature. It is most
important that you follow the guide-
lines in these instructions to prevent the
possible formation of condensation in
the venting system.
As a Category furnace it may be vent-
ed vertically with type B-1 vent pipe and
also may be common vented, as
described in these instructions.
IMPORTANT APPLICTION
NOTES
When the furnace is used as a
replacement, the existing vent sys-
tem should be inspected to assure
that there are no obstructions, block-
age, or any signs of corrosion and is
properly sized for use with this fur-
nace.
NOTE: When the vent table permits
more than one diameter of pipe for a
connector or vent, the smallest per-
mitted diameter must be used.
Vent pipe may be type "B-1," either
rigid or suitable flexible construction
that carries a u.l. listing.
Common venting is allowed with
vertical B-1 vent systems, and lined
masonry chimneys. Follow the
National Fuel Gas Code, ANSI
Z223.1 and/or the Natural Gas
Installation Code, CSA-B149.1 & .2
for proper installation practices.
NOTE: Follow combustion air
instructions as outlined in this manu-
al.
Single wall vent connectors to "B-1
vent or masonry chimneys" may be
used under the guidelines of the
National Fuel Gas Code, ANSI
Z223.1 and/or the Natural Gas
Installation Code, CSA-B149.1 & .2.
The entire length of the vent con-
nector shall be readily accessible
for inspection, cleaning and
replacement.
