Combustion Air and Venting

7

SECTION II - Providing Air for

Combustion and Ventilation

The installer must provide adequate

combustion and ventilation to the area in

which the ELITE is installed. Providing

adequate air ensures proper combustion

and reduces the potential risk of severe

personal injury or death from carbon

monoxide emissions if a flue gas leakage

occurred.

The installer should not install an

exhaust fan in the room with the ELITE.

The exhaust fan could affect the combus-

tion of the burner or cause potential flue

gas leakage resulting in severe personal

injury or death.

The installer should take the condition

and age of the building when determin-

ing air for ventilation. Older building

(buildings with single pane windows and

minimal weather-stripping around doors

and windows) tend to have adequate nat-

ural infiltration and ventilation without

providing dedicated air openings.

Newer buildings (buildings with double

pane windows and weather-stripped

doors and windows) are unlikely to have

natural infiltration and ventilation, thus

must be provided with dedicated air

openings.

The installer must follow the requirements of

state, provincial or local codes when sizing and

locating adequate air openings for combustion

and ventilation.

In absence of the codes the installer may opt to

use the following guidelines when the ELITE

is installed in a confined room as defined by

NFPA 31 as a room with less than 7200 cubic

feet per 1 GPH of input of all appliances locat-

ed in the area (7200 cubic feet is define as a

room with 8 foot ceiling and 33.5 ft x 33.5 ft in

dimension):

Two Permanent Openings - One opening

must commence within 12 inches of the ceiling

and the other opening within 12 inches of the

floor. The opening must have a minimum

height or length dimension of 3 inches, the

actual dimensions are based on:

Using Inside Air - Each opening must be con-

nected freely to the areas having adequate infil-

tration from the outside. Each opening should

be at least 140 sq. inches per 1 GPH of input (1

sq. inch per 1000 BTU input). This input

should include all appliances (gas and/or oil)

plus any appliances that may draw air from the

room such as clothes dryers.

Using Outside Air - Each opening should be

connected directly or by ducts to the outdoors

or to a crawl space or attic area that is freely

connected with the outdoors. The openings

should be sized as follows:

Through outside wall or vertical ducts -

The openings should be a minimum 35 sq

inches per 1 GPH input (1 sq. inch per 4000

BTU input) of all appliances (gas and/or

oil) plus any appliances that may draw air

from the room such as clothes dryers.

Through horizontal ducts - The openings

should be a minimum 70 sq. inches per 1

GPH input (1 sq. inch per 2000 BTU input)

of all appliances (gas and/or oil) plus any

appliances that may draw air from the room

such as clothes dryers.

Where ducts are used, the size of the duct

should equal the free area of the opening in

which the duct is connected to.
