A. Venting Termination Requirements
CAUTION
Do not terminate vent in any enclosed or
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
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)
•
•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
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 appliances.
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
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.
