7 Vent Information

A. Venting Termination Requirements

CAUTION

Do not terminate vent in any enclosed or semi-enclosed area such as a carport, garage, attic, crawl space, under a sun deck or porch, narrow walkway or closely fenced area, or any location that can build up a concentration of fumes such as a stairwell, covered breezeway, etc.

1. Termination must exhaust above air inlet elevation. It is strongly recommended that at least 1.5m of vertical pipe be installed when appliance is vented directly through a wall. This will create a natural draft, which will help prevent the possibility of smoke or odor venting into the home during a power outage. It will also keep exhaust from causing a nuisance or hazard by exposing people or shrubs to high temperatures. The safest and preferred venting method is to extend the vent vertically through the roof.

2. Distance from doors and opening windows, or gravity or ventilation air inlets into building:

a.Not less than 1.2m below;

b.Not less than 1.2m horizontally from;

c.Not less than 305mm above.

3. Distance from permanently closed windows;

a.Not less than 305mm below; horizontally from or above.

4. Distance between bottom of termination and grade should be 305mm minimum. This is conditional upon plants in the area, and nature of grade surface. The grade sur- face must be a non-combustible material (i.e., rock, dirt). The grade surface must not be lawn. Distance between bottom of termination and public walkway should be 2.13m minimum.

5. Distance to combustible materials must be 610mm minimum. This includes adjacent buildings, fences, protruding parts of the structure, roof overhang, plants and shrubs, etc.

6.Termination Cap Location (Home Electrical Service)

•Side-to-side clearance is to be the same as minimum clearance to vinyl inside corners.

•Clearance of a termination cap below electrical service shall be the same as minimum clearance to vinyl soffits.

•Clearance of a termination cap above electrical service will be 305mm minimum.

•Location of the vent termination must not obstruct or interfere with access to the electrical service.

B. Avoiding Smoke and Odors

Negative Pressure, Shut-Down and Electrical Power Failure

To reduce the probability of back-drafting or burn-back in the pellet appliance during power failure or shut down con- ditions, it must be able to draft naturally without exhaust blower operation.

Negative pressure in the house will resist this natural draft if not accounted for in the pellet appliance installation.

Heat rises in the house and leaks out at upper levels. This air must be replaced with cold air from outdoors which flows into lower levels of the house.

Vents and chimneys into basements and lower levels of the house can become the conduit for air supply and reverse under these conditions.

Outside Air

An outside air kit is recommended in all installations. The Outside Air Kit must be ordered seperately.

Per your local building codes, consideration must be given to combustion air supply to all combustion appliances. Failure to supply adequate combustion air for all appliance demands may lead to backdrafting of those and other appli- ances.

When the appliance is roof vented (strongly recommended):

The air intake is best located on the exterior wall ori- ented towards the prevailing wind direction during the heating season.

When the appliance is side-wall vented:

The air intake is best located on the same exterior wall as the exhaust vent outlet and located lower on the wall than the exhaust vent outlet.

The outside air supply kit can supply most of the demands of the pellet appliance, but consideration must be given to the total house demand.

House demand may consume the air needed for the appli- ance. It may be necessary to add additional ventilation to the space in which the pellet appliance is located.

Consult with your local heating professional to determine the ventilation demands for your house.
