VENT INFORMATION
Begin the vent system installation by identifying the path
the vent will take from the fireplace to the power-vent.
Verify clearances are met throughout the entire path of the
venting system.
Determine how the vent system will be terminated,
(vertically or horizontally). Verify clearances for the
termination.
NOTICE: If terminated vertically, DVKCVP (Vertical
Conversion Kit) is required.
NOTICE: This Power-Vent cannot be vented out the rear
of the fireplace.
NOTICE: This Power-Vent can only be used with DuraVent
Direct Vent Pro® 4 X 6-5/8 inch piping.
NOTICE: All outer connection joints must be sealed
with aluminum tape or silicone sealant rated above
300°F/149°C. The inner flue joints do not require any
sealant.
This power vent can be routed in any
path as long as it meets the following
requirements:
• Maximum vertical distance above fireplace floor=50 ft
• Maximum effective length =
50 ft
(effective length
calculations shown in
Equation 1
on next page).
• Minimum effective length = 2 ft *
• Maximum 6-90° elbows or 12-45° elbows
• Maximum 5 ft below the base of the fireplace
• Maximum drop of 12 ft from highest point in run.
• If vent pipe runs downward it cannot turn back upward.
