Wall Mounted Variable Speed Control Option:
The Following instructions are only needed if you
have a wall switch which is dedicated to turn the
Junction Box(120v Power Supply) in the vent space
under the rebox ON/OFF.
AND, you wish to replace this switch with the
Variable Speed Control.
•You will need a wire stripping tool, crimping tool,
11/16 socket or wrench, and phillips screw driver.
**Make sure Power/Circuit Breaker to the existing
switch and Gas are still off if choosing this option.**

Step B: Use wire stripping tool- Strip black wire
coming from 3-prong plug and black wire going to
thermodisc 1/4 inch, twist bare wires. (Figure: 10)
Figure: 10
Take the ends of black wires in previous step and
insert the ends into opposite sides of the provided
Crimp Butt Connector. Use crimping tool to make
two crimps on the Crimp Butt Connector; one
on each side of center. This will rmly hold both
wires in place. (Figure:11)
Figure: 11
Step C: Use wire stripping tool- Remove yellow
bands from black and white wire ends and strip (1/2
- 3/4 inch) coming from Variable Speed Control
(Figure: 11)
Pull the knob off the Variable Speed Control; you
will see a lock nut, use a 11/16 socket or wrench to
remove it.
The stem of Variable Speed Control goes through
hole of Face Plate, tighten lock nut back on stem.
Put knob on stem. (Figure: 12)
Step D: Remove existing dedicated switch from wall
and disconnect attched wires. Take one of the Hot
wires and twist it with either white or black wire
coming from speed control, take these two twisted
wires and press them into one blue wire nut. While
pressing, twist wire nut in clockwise direction - this
will tighten the wire nut onto twisted wires. Repeat
this process with the other Hot wire and 2nd wire
from speed control. Properly ground any Ground
wire to metal switch box housing. Secure face plate
to switch box with included 2 screws using phillips
screw driver.
•Go back to Step 3.
