From National Fuel Gas Code — Table E.1.1(d)
General Venting
FURNACE EXHAUST MUST BE VENTED TO THE
OUTDOORS. THESE FURNACES ARE INDUCED DRAFT
VENTED AND MUST N N O O T T BE CONNECTED TO ANY
VENT SERVING ANOTHER APPLIANCE. PLEASE NOTE
THAT THESE FURNACES USE P P O O S S I I T T I I V V E E - - P P R R E E S S S S U U R R E E
VENT SYSTEMS.
Proper venting is essential to obtain maximum
efficiency from a condensing Furnace. Proper
installation of the vent system is necessary to assure
drainage of the condensate and prevent deterioration
of the vent system.
ETL has certified the design of condensing Furnaces for
a minimum of 0" clearance from combustible materials
to single wall plastic vent pipe.
The recommended system is assembled from 2" or 3"
plastic pipe and fittings found in the Approved Vent
Pipe Materials Table. Where the system is routed to the
outdoors through an existing masonry chimney
containing flue products from another gas appliance,
or where required by local codes, then 3" venting of
Type 29- 4C stainless steel must be used in place of
PVC material.
These Furnaces have been classified as CATEGORY IV
Furnaces in accordance with ANSI Z21.47 "latest
edition" standards. Category IV - a central furnace that
operates with a positive vent static pressure and with a
flue loss less than 17 percent. These conditions require
special venting systems, which must be gas tight and
water tight.

N N o o t t e e : : When an existing Furnace is removed from a
venting system serving other gas appliances, the
venting system is likely to be too large to
properly vent the remaining attached appliances.
I I m m p p o o r r t t a a n n t t : : These Furnaces may be installed as Direct
Vent (sealed combustion) or as Nondirect
Vent (single pipe). The Furnaces are
shipped DIRECT VENT with sealed
combustion.
I I m m p p o o r r t t a a n n t t : : Products installed in Canada must use vent
systems that are certified to the Standard
for Type BH Gas Venting Systems (ULC
S636) for Class II-A venting systems (up to
65°C). Components of the vent system
must not be interchanged with other vent
systems or unlisted pipe or fittings. Plastic
components, specified primers, and glues
must be from a single system manufacturer
and not intermixed with other system
manufacturer's vent system parts. In
addition, the first three feet of the vent pipe
must be visible for inspection.
