Fan / oven interlock relay instructions
The interlock relay system is an option available from Wood Stone. With the interlock relay option, when the oven
is turned on, the interlock relay is energized, allowing power to flow to the exhaust fan serving the oven. The fan
will turn on with the oven.
Wire the incoming 120 VAC to the oven J-box as instructed in the
Assembly Connections
section of this manual.
Mount the fan control relay into a junction box, and fan speed controller into a single gang junction box under the
oven near the back of the stand. Bring in the 120 VAC power for the roof mounted Enervex fan. The line wire will
pass through the relay on the black wires (terminals 5 and 9), then through the fan speed controller before going
out to the fan. Turn the fan speed controller fully clockwise to the LOW position initially. See the
Venting
section
of this manual for instructions on setting the fan speed. Once the fan speed is correctly set, it will not need to
change.
Unplug the power harness from the gas valve on the back of the control box. Plug side “A” of the interconnect
harness into the gas valve, then plug the power harness into the gas valve, then plug the power harness into side
“B” of the interconnect harness.
Turn on the oven control. The relay should close and switch on the fan. When the oven is turned off, the fan will
switch off.
* Relay rated for 10 A. If fan current will exceed 10 A, use an additional
motor contractor, installed after the relay. to switch power to the fan.
An ongoing program of product improvement may require us to change specifications without notice.
