Installing an In-Line Linear Power Vent (LDVPV58)
This section applies to installations where an external roof
or wall mounted power vent is not aesthetically acceptable
or feasible.
Venting Layout
Selection of components and details of venting lay out should
adhere to the following guidelines:
Ensure there is a minimum run of 2' of straight pipe between
„
the fireplace and the power vent
Ensure the maximum vent run does not exceed 60'
„
Maximum vent run must be reduced by 10' for 1' of pipe
„
running in a vertical downward direction
Ensure the number of 90º elbows does not exceed 3 (maximum
„
allowable vent run must be reduced by 10' for every additional
90º elbow added)
Ensure the number of 45º elbows does not exceed 6

operation of the fireplace, and may be hazardous.
■ In heavy snow areas, take extra care to prevent snow buildup from obstructing the vent
termination.
