VENT HOOD TERMINATION CODE REQUIREMENTS FOR CANADIAN INSTALLATIONS
If possible, locate the Vent Hood on a wall that does not face the direction of prevailing winds. This will diminish the
possibility of appliance interruption during periods of extreme winds and prevent oil odors caused by backdrafts.

TER

damage from heat or condensate from the flue gases.

POWER VENTER INSTALLATION
VERIFY POWER VENTER MODEL SELECTION USING TABLES ON PAGE 1.
CODE REQUIREMENTS
All Power Venter installations must follow the appropriate U.S. or Canadian requirements listed under the Installation Restrictions and
Cautions of this manual.
• All portions of the vent system under positive pressure during operation (on the outlet side of Power Venter) shall be designed and
installed so as to prevent leakage of flue or vent gases into the building.
• All appliances must enter the vent system on the inlet side of the Power Venter.
• Provision shall be made to interlock the appliance(s) to prevent the flow of gas to the main burners when the draft system is not
performing so as to satisfy the operating requirements of the equipment for safe performance. See “Electrical Wiring” section of
