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™)

WARNING

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.
