GENERAL INFORMATION
Vent the furnace in accordance with
these instructions, National Fuel Gas
Code, ANSI Z223.1 and/or the Natural
Gas Installation Code, CAN/CGA-
B149.1 & .2 and requirements or codes
of the local utility or other authority
having jurisdiction.
IMPORTANT: THIS FURNACE IS
NOT CERTIFIED FOR USE WITH A
POWER VENTER OR ANY OTHER
TYPE OF HORIZONTAL VENTING.
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
MANUFACTURER, CANNOT AND
WILL NOT BE RESPONSIBLE FOR
INJURY OR DAMAGE CAUSED BY
THE USE OF SUCH UNTESTED
AND/OR UNCERTIFIED DEVICES,
ACCESSORIES OR COMPONENTS.
DRAFT INDUCER
IMPORTANT:
Pre-drill vent pipe
attaching holes in the draft inducer
collar to prevent plastic material from
cracking. Drill
1
⁄
8
(
diameter holes
through vent pipe and collar and use
#8 screws to attach. See Figure 9.
NOTE:
On downflow units, be certain
that the vent pipe is positioned over
the induced draft motor outlet. Attach
the vent pipe to the induced draft
motor collar as noted above.
IMPORTANT APPLICATION
NOTES
When the furnace is used as a
replacement, the existing vent system
should be inspected to assure that
there are no obstructions, blockage, or
any signs of corrosion.
IMPORTANT:
WHEN THE VENT
TABLE PERMITS MORE THAN ONE
DIAMETER OF PIPE FOR A
CONNECTOR OR VENT, THE
SMALLEST PERMITTED 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, CAN/CGA-B149.1 & .2 FOR
PROPER INSTALLATION PRACTICES.
IMPORTANT:
WHEN COMMON
VENTING, USE B-1 VENT
CONNECTORS.
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, CAN/CGA-
B149.1 & .2.

FURNACE CATEGORY
INFORMATION
This furnace is shipped as a Category
I
type induced draft furnace. A Category
I
furnace operates with a nonpositive
vent pressure and has a vent gas
temperature at least 140°F above the
dew point of the vent gases. A
Category
I
type may be a draft hood
equipped furnace 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 guidelines in these
instructions to prevent the possible
formation of condensation in the
venting system.
As a Category
I
furnace it may be
vented vertically with type B-1 vent
pipe and also may be common vented,
as described in these instructions.
