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, DVKCV (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. If your fireplace is
equipped with 5 X 8 inch connections you will need to use
the SD58DVAX46 Decreaser.
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.

Maximum vertical distance above Fireplace floor=60 ft
Maximum effective length = 110 ft (effective length
calculations shown below in Equation 1).
Minimum effective length = 15 ft
– DVCT units must have the fireplace damper door
fully open for any run less than 25 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.

NotICE: Once vent runs in downward direction it cannot
turn back upward.
NOTICE: If this Power-Vent will be serviced from the
rear side a minimum of 12 inches of vent pipe must be
removable to gain clearance for removal of the rear panel.
This can be achieved with an adjustable pipe that will
collapse to clear the Power-Vent connector flange and
then be removed. This can also be achieved by breaking
the connection at the nearest elbow and removing that
section of pipe.
Ensure the sidewall venting clearances are observed. If
venting system is installed below ground, we recommend
a window well with adequate and proper drainage to be
installed around the termination area.

Installing Firestops
Installing Support Brackets
Firestops are required for safety whenever the vent system
passes through an interior wall, an exterior wall, or a ceiling.
These firestops act as a firebreak heat shield and as a
means to insure that minimum clearances are maintained
to the vent system.
A horizontal pipe support MUST BE used for each 3 feet of
horizontal run. The pipe supports should be placed around
the pipe and nailed in place to framing members. There
MUST BE a 3 inch clearance to combustibles above 6-5/8
inch diameter pipe and elbows and 1 inch clearance on both
sides and bottom of 6-5/8 inch pipe to combustibles on all
horizontal pipe sections and elbows.
Position the firestops on both sides of the 10 x 11 inch hole,
previously cut. Secure with nails or screws. The heat shields
of the firestops MUST BE placed towards the top of the hole.
Continue the vent run through the firestops. See Figure 14.
Figure 12
note: Maintain at least 1/4 inch rise for every 12 inches
of vent run.
Horizontal runs in the vent system which pass through either
interior or exterior walls, require the use of wall firestops on
both sides of the wall through which the vent passes.
Vertical runs of this vent systems must be supported every
4 feet above the appliance flue outlet by wall brackets
attached to the 6-5/8 inch vent pipe and secured with nails
or screws to structural framing members.
Figure 14
Page 8
38730-2-0519
Vertical runs of this system which pass through ceilings
require the use of one ceiling firestop at the hole in each
ceiling through which the vent passes.
Position a plumb bob directly over the center of the vertical
vent component and mark the ceiling to establish the center
point of the vent. Drill a hole or drive a nail through this center
point and check the floor above for any obstructions such as
wiring or plumbing runs. Reposition the appliance and vent
system, if necessary, to accommodate ceiling joists and/or
obstructions.
Cut a 10 inch x 10 inch hole through the ceiling, using the
center point previously marked. Frame the hole with framing
lumber the same size as the ceiling joists. See Figure 15.
If the area above the ceiling is NOT an attic, position and
secure the ceiling firestop on the ceiling side of the previously
cut and framed hole. See Figure 16. If the area above the
ceiling is an attic, position and secure the firestop on top of
the previously framed hole. See Figure 17.
NOTE: Remove insulation from the framed area in the attic
before installing the firestop and/or vent pipes.
Figure 17
Vent Pipe Clearance
Notice: Maintain one inch of clearance around vertical
vent pipe. See Figure 18.
For horizontal vent, maintain a minimum 1 inch clearance
to the bottom and sides of the vent, and 3 inch clearance
to combustibles above the vent pipe. See Figure 19.

MAINTENANCE AND SERVICE
This Power-Vent has no user-serviceable mechanical
components. Contact your dealer or a qualified gas
appliance service technician for all service and repair.
CHECK VENT SYSTEM
The fireplace and venting system should be inspected
before initial use and at least annually by a qualified service
person. Inspect the external vent cap on a regular basis to
make sure that no debris is interfering with the air flow.
Note: Inlet air box paint cannot be cured above 190° F, due
to a vacuum switch that is permanently attached to the box.
General Information
Note: The Power-vent inducer fan will run for 15 seconds
after the fireplace is turned on. After this pre-purge time
the ignition sequence will be initiated.
Note: The Power-vent inducer fan will run for 120
seconds after the fireplace is turned off to purge the
system of exhaust gases.
Painting Power-Vent
Front fascia and inlet air box can be painted if desired.
All surfaces to be painted must be thoroughly cleaned
and scuffed with steel wool. Paint must have temperature
rating over 750° F.
