Exterior wall opening:
Determine the exact position of the Heli-Fire so that the venting pipe is centered between two building
framing members. Consult your local building codes prior to proceeding.
IMPORTANT: When locating the opening, it should be noted that venting terminal clearances
must be maintained. See “Vent Terminal Minimum Clearances” & “Power Venting
Clearances” on page 26 for proper clearances.
Note: When using a surface mount power vent on a flat roof, the power vent must be attached
atop an elevated platform in order to keep it clear of snow and water accumulations .
Use only pipe supplied with the power vent kits and extension kits.
