Specifications subject to change without notice.

General

If this furnace replaces a furnace that was connected to a vent

system or chimney, the vent or vent connectors of other

remaining appliances may need to be re

−

sized. Vent systems

or vent connectors of other appliances must be sized to the

minimum size as determined using appropriate table found in

the current edition of National Fuel Gas Code NFPA 54/ANSI

Z

−

223.1. In Canada, refer to CAN/CSA

−

B149.1

An abandoned masonry chimney may be used as a raceway

for properly insulated and supported combustion

−

air (when

applicable) and vent pipes. Each furnace must have its own set

of combustion

−

air and vent pipes and be terminated

individually, as shown in 

Figure 47

 for Direct Vent (2

−

Pipe)

system, or 

Figure 48

 for single

−

pipe or ventilated combustion

air option.
A furnace shall not be connected to a chimney flue serving a

separate appliance designed to burn solid fuel. Other gas

appliances with their own venting system may also use the

abandoned chimney as a raceway providing it is permitted by

local code, the current edition of the National Fuel Gas Code,

and the vent or liner manufacturer’s installation instructions.

Care must be taken to prevent the exhaust gases from one

appliance from contaminating the combustion air of other gas

appliances.
Do not take combustion air from inside the chimney when using

ventilated combustion air or single

−

pipe vent option.

These furnaces can be vented as direct

−

vent (two

−

pipe),

ventilated combustion air, or non-direct (single

−

pipe) vent

system. Each type of venting system is described below.

Common venting between these furnaces or other appliances

is prohibited.

Materials

U.S.A.

Combustion air and vent pipe, fittings, primers, and solvents

must conform to American National Standards Institute (ANSI)

standards and American Society for Testing and Materials

(ASTM) standards. See 

Table 13 

for approved materials for

use in the U.S.A. This furnace is also CSA approved for venting

with M&G DuraVent

®

 PolyPro

®

 polyproplylene venting

systems.

Canada

Special Venting Requirements for Installations in Canada

Installation in Canada must conform to the requirements of

CAN/CSA B149 code. Vent systems 

must 

be composed of

pipe, fittings, cements, and primers listed to ULC S636. M&G

DuraVent PolyPro polyproplylene venting systems are ULC

S636 listed.

NOTE

:  When using polypropylene venting systems, all venting

materials used, including the vent terminations, must be from
the same manufacturer.

WARNING

!

CARBON MONOXIDE POISONING HAZARD

Failure to follow the instructions outlined in Locating the

Vent Termination for each appliance being placed into

operation could result in carbon monoxide poisoning or

death.

For all venting configurations for this appliance and other

gas appliances placed into operation for the structure,

provisions for adequate combustion, ventilation, and di-

lution air must be provided in accordance with:

U.S.A. Installations:

 Section 9.3 NFPA 54/ANSI

Z223.1 1

−

2012, Air for Combustion and Ventilation and

applicable provisions of the local building codes.

Canadian Installations:

 Part 8 of

CAN/CSA

−

B149.1

−

10. Venting Systems and Air

Supply for Appliances and all authorities having

jurisdiction.

NOTICE

RECOMMENDED SUPPORT FOR VENT

TERMINATIONS

It is recommended that sidewall vent terminations of

over 24 inches (0.6 M) in length or rooftop vent termin-

ations of over 36 inches (1 M) in length be supported

by EITHER the factory accessory vent termination kit

or field-supplied brackets or supports attached to the

structure. A factory accessory vent termination kit may

be used for direct vent terminations. Termination kits

are available for 2-in. or 3-in. pipe. See 

Table 12

 for

available options.

−

Pipe System

In a direct

−

vent (2

−

pipe) system, all air for combustion is taken

directly from outdoor atmosphere, and all flue products are

discharged to outdoor atmosphere. Combustion-air and vent

pipes must terminate together in the same atmospheric

pressure zone, either through the roof (preferred) or a sidewall.

National code authorities.
