plate. The drill bit must be long enough to penetrate to the building exterior.
2. Using a reciprocating saw, cut a hole through the building siding, wall board, etc., following the appropriate lines of the template.
3. Slide the Vent Hood through the opening and fasten to exterior wall using screws provided.
4. Once Power Venter and vent pipe are completely installed and secured, apply a bead of caulk between the Vent Hood flange and
exterior of building.

and Propane Installation Code, CAN/CSA-B149.1” or the “National Fuel Gas Code, ANSI Z223.1 (NFPA 54)”:
• 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
