TERMINATION CLEARANCES FOR CANADIAN INSTALLATIONS
The SS1-R has been CSA 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

• Above grade level or any surface that may support snow, ice, or debris
It is not recommended for the SS1-R to be terminated 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 heating equipment operation.
