Venting and Combustion Air Installation

SECTION VI - Venting and

Combustion Air Installation

General Requirements

- Installation must comply with local

requirements and with the National

Fuel Gas Code, NFPA 54/ ANSI Z223.1

for U.S. installations and CSA B149.1

or B149.2 for Canadian installations.

- The PERFORMANCE PLUS requires

a special vent system designed for pres-

surized venting and is rated as ANSI

Z21.13 Category IV (pressurized vent

system, likely to condense within the

vent system).

- The PERFORMANCE PLUS may be

direct vented with outside combustion

air or non-direct vented using room air.

- The PERFORMANCE PLUS is

approved for the following vent manu-

facturers:

• Heat Fab (Saf-T-Vent

®

)

• ProTech Systems (FasNSeal

®

)

• Flex-L (StaR-34)

• Z-Flex (Z-Vent III

™

)

DO NOT mix components from different

systems. The vent system could fail or

improperly seal, causing leakage of flue

products into the building.

Category IV Vent Termination - Guidelines

Locate the vent termination for direct or non-

direct vent applications using the following

guidelines:

1. The total equivalent length of the vent

should not exceed 100 feet as given in

Table 2, page 33.

2. The installer must consider the following

when determining the location of the vent

termination:

- Locate the vent termination where flue

vapors will not damage surrounding

shrubs, plants or air conditioning equip-

ment or be objectionable to the home-

owner.

- The flue products will form a notice-

able plume as they condense in colder

air. Avoid terminating the vent in areas

where the plume could obstruct win-

dow views.

- Prevailing winds could cause freezing

of flue condensation and a buildup of

water / ice on surrounding plants, build-

ing surfaces or combustion air inlet.

- Avoid locations of possible accidental

contact of flue vapors with persons or

pets.

- Avoid locations where prevailing winds

could affect the performance of the unit

or cause recirculation of the flue gases,

such as inside corners of buildings or

near adjacent buildings or vertical sur-

faces, window wells, stairwells,

alcoves, courtyards, or other recessed

areas.

- Do not terminate the vent above any

doors or windows; flue condensate

could freeze causing ice formations.

- Locate or guard the vent termination to

prevent possible condensate damage to

exterior finishes.

3. The vent termination and vent pipe must

not extend more than 12 inches beyond the

exterior wall. The vent termination for the

horizontal concentric snorkel kit must not

extend more than 24” beyond the exterior

wall.

4. Do not connect or terminate any other

appliance to the vent system or multiple

units into a common vent system.
