2.0 VENTING
2.1 Venting Requirements
• For information on standard procedures for venting the
appliance, refer to the venting section of your specic appliance
installation manual.
• The #KPV is for use 4" x 6-5/8" coaxial rigid direct vent pipe. A 5"
x 8" to a 4" x 6-5/8" vent reducer for DuraVent and Selkirk vent
systems must be used. See appliance installation manual for
approved venting.
• A minimum of 1 in (25 mm) clearance on all sides of the
vertical vent pipe must be maintained. Attic insulation shields
may be insulated using unfaced insulation products listed as
noncombustible per ASTM E 136.
• A minimum of 1 in (25 mm) clearance on all sides of the
horizontal vent pipe at the wall pass-through must be
maintained. Wall thimble products that comply with the required
1 in (25 mm) clearance to combustibles must be installed for all
horizontal vent runs that pass through interior or exterior walls.
These wall thimble products may be insulated using unfaced
insulation products listed as noncombustible per ASTM E 136.
• For every 1 ft of vertical drop, the total allowable length must be
reduced by 2 ft.
• If a pipe conguration includes a vertical component that goes
downward, a vertical component going back upward is not
allowed.
• Before installation, apply a bead of the provided sealant around
the inner exhaust pipe connection on the replace and the
power vent assembly. See Figures 2.1 and 2.2. Each individual
pipe manufacturer may require or recommend additional sealant
in between each vent pipe connection. After completing the
vent pipe installation, ensure all of the vent pipe connections are
sealed properly before replace operation.
2.1.1 Unit Specic Venting Requirements
• The Callaway-72 starts with a 5" x 8" 45° elbow o the back of
the appliance. Use a required 4" x 6-5/8" reducer o the elbow to
keep venting inside the minimum chamber requirements.

8. Proceed to Section 3.5.1 Finishing Materials on page 13.

Kozy Power Vent #KPV Hussong Mfg. Co., Inc. • Kozy Heat Fireplaces 13
3.5.1 Finishing Materials
NOTE: A #KPV-FEK Finishing Extension Kit will be needed for
installations with exterior nishing materials greater than 1" thick.
Order with the appliance and venting system. It will be used to ensure
that the nishing is done to appropriate size for the #KPV-FEK to be
installed properly.
IMPORTANT: IT IS IMPERATIVE THAT #KPV-FEK IS LEVEL TO ENSURE THE
POWER VENT IS LEVEL. THIS IS REQUIRED TO ENSURE PRECIPITATION
DOES NOT BUILD UP INSIDE THE CAP. Care should be taken to ensure
#KPV-FEK is secured at to the wall.
NOTE: Sealant used must have a minimum of 300°F continuous
exposure rating.
If installing nishing material less than 1 inch thick, skip to Step 10 on
the next page.
1. Place assembled box over the framed opening in the wall with
outside anges oriented vertically and held tight to the building
exterior.
2. Drive two of the supplied wood screws through opposite ends
of the two outer anges. This will secure #KPV-FEK extension
box to the building and allow for squaring of the #KPV-FEK. See
Figure 3.14. Seal all corners, joints, and bend lines with silicone
caulk. Ensure all gaps and holes are lled so a sealed envelope is
formed.
3. The wall is now ready to be nished. Finishing materials such as
stone, marble, or brick can then be applied up to the anges of
the #KPV-FEK that protrude perpendicular to the wall. This will
ensure that the cap will t into the opening after nishing has
been completed.
NOTE: Outside anges of the #KPV-FEK must not have any pressure on
them from the nishing materials. This could cause the opening left
after nishing to be too small.
4. After the #KPV-FEK has been installed and the nishing of the
wall is completed, apply a bead of silicone to the #KPV-FEK
around the entire metal ange.
5. Apply a bead of silicone along the backside of the entire metal
ange of #KPV. Align with #KPV-FEK as shown in Figure 3.15.
Ensure cap is level and square, then secure #KPV to #KPV-FEK
with (8) screws.
6. Reinstall the #KPV back assembly that was removed in Step 1 of
Section 3.5. See Figure 3.16
7. After the #KPV has been secured to the #KPV-FEK, silicone should
be applied around the outer edge of #KPV-FEK where it meets
the building exterior. Silicone should also be applied where #KPV
and #KPV-FEK meet, as shown in Figure 3.17 on the following
page.
8. Place decorative cover onto cap and fasten. Once cover has been
secured, installation is complete.
9. Place a bead of silicone on the back side of the mounting ange
for the cap. See Figure 3.18 on the next page. Instructions
continue on the next page.

4.0 ELECTRICAL INFORMATION
4.1 Wiring to the Appliance
NOTE: Electrical wiring must be done in accordance with national,
provincial, and/or local electrical codes.
WARNING: Disconnect electrical power from replace/power vent
before performing any maintenance, repair, or electrical wiring.
NOTE: Electrical service of 120 VAC-60Hz must be supplied to the
junction box of the replace in order for the power vent to operate
correctly. The current draw of this device is 0.85 amperes.
Ensure that the proper clearances are maintained for wiring and
conduit. When installing the wiring, it must never run above the vent
run and it must be a minimum 1" from all venting.
The battery back up will not run with power venting installed.
4.1.1 Prepare Control Board
1. Use a at blade screwdriver to pry the tabs of the top cover of
the control module to release.
2. Locate the JP1 jumper. It is a small plastic jumper that connects
two pins as shown in Figure 4.2.
3. Pull the plastic jumper straight up to expose the two individuals
pins underneath it. This changes the control module function
from a natural draft system to a power vent system. See Figure
4.3.
