Wiring The Power Vent - Hearth and Home Technologies PVK-80 Installation Instructions Manual

6. Two support braces are provided and MUST be
used to mount the PVK-80 horizontal cap to the
wall. Screw one end of each brace to the bottom
of the cap housing, using the pilot holes in the cap.
Extend each brace until it contacts the building wall
and tighten the bolt/nut in the center of each brace.
Fasten the other end of each brace to the outside
wall. See Figure 4.

WIRING THE POWER VENT

:
Note Electrical wiring must be done in accordance with
national, provincial, and/or local electric codes.
Note: Some fi replace models may have unique wiring
requirements when used with the PVK-80. In those cases,
PVK-80 instructions those manuals supersede these
instructions.
CAUTION:
Before performing any maintenance,
repair, or electrical wiring to the fi replace/power vent,
make sure the electrical power is fi rst disconnected to
the fi replace/power vent.
1. A 7/8 in. diameter hole must be bored in the side of
the fi replace outer wrap in which the 5 wires from
the power vent will be routed. The hole should be
located 2 inches to the side of the junction box and
4 inches up from the base of the fi replace. See
Figure 5.

Note: The PVK-80 Power Vent includes a 6-1/2 foot
5-wire assembly wired into the vent cap fan motor.
If this wire assembly will not reach the fi replace, the
wires may need to be spliced to additional wire lengths
in a junction box installed inside the building. Follow
applicable electric codes.
2. Place the PVK-80 terminal block/wiring harness
assembly in the cavity under the fi replace next to
the valve assembly.

3. Route the 6 wires from the power vent through
the 7/8 inch diameter hole bored in the fi replace
wrap, using a strain relief connector to secure the
wires in place. Connect the black, white, brown
and red wires from the power vent assembly to
the terminal block. Connect the green wire to the
ground stud of the junction box.
CAUTION: Make sure the cable is NOT in the path of
the hot exhaust air. This will cause the wire insulation
to melt and the Power Vent to malfunction.
CAUTION: Carefully match the corresponding
colored wires to the appropriate position on the
terminal block. See Figure 6.

Note: To insert a wire into the terminal block use a blunt
object such as a needle nose pliers and depress the spring
loaded pin on the top of the block and at the same time insert
the wire into the side of the terminal block. Release the pin
to secure the wire in place.
