• The bottom of the vent terminal shall be located at least 12 inches above grade.
• The exit terminal shall be so arranged that the flue gases are not directed so as to jeopardize people, overheat combustible structures
or enter buildings.
• Not to be less than 10 feet from an adjacent building.
The SS2 is also Listed to terminate a minimum of 12” below, above or horizontally from a soffit, deck or adjacent sidewall.

VENT HOOD TERMINATION CLEARANCES FOR CANADIAN INSTALLATIONS
The SS2 has been Listed according to the requirements of “Mechanical Flue-Gas Exhausters” CSA Std B255-M81 and the “Installation code for Oil
burning Equipment” CSA Std B139-M91, (See Diagram A1).
• A venting system shall not terminate underneath a veranda, porch, or deck, or above a paved sidewalk or a paved driveway that is
located between two buildings, and that serves both buildings.
• The exit terminals of mechanical draft systems shall not be less than 2.13m (7ft) above grade when located adjacent to a paved sidewalk or driveway.
• A venting system shall not direct flue gases towards brickwork, siding, or other construction, in such a manner that may cause damage
from heat or condensate from the flue gases.
• A venting system shall not direct flue gases so as to jeopardize people, overheat combustible structures, or enter buildings.
A venting system shall not terminate within 1.8 m (6ft) of the following:
• A window, door or mechanical air supply inlet of any building, including soffit openings
• A gas service regulator vent outlet
• A combustion air inlet
• A property line
• A direction facing combustible materials or openings of surrounding buildings
A venting system shall not terminate within 1m (3ft) of the following:
• Above a gas meter/regulator assembly within 1m (3ft) horizontally of the vertical centreline of the regulator
• A oil tank or an oil tankfill inlet
• The inside corner of an L-shaped structure
If possible, do not terminate the SS2 on a wall that faces the direction of the prevailing winds. Backdrafts by
severe winds can cause oil odors to remain in the structure and/or interrupt equipment operation.
