Mounting Junction Box; Pressure Switch Sensing Tube Installation; Draft Control Installation - Field Controls CK-91FV Quick Start Manual

MOUNTING JUNCTION BOX

The junction box can be mounted at the venter or remotely mounted
away from the venter. (See Figure 1 & Figure 2)
1. Remove one of the knockouts from the side of the junction
box where the pressure switch is mounted. Install the fl exible
conduit connector onto the CK-91FV junction box and secure
with fastening nut. If remote mounting the CK-91FV junction
box, mount the fl exible conduit connector onto a 2" x 4"
installer supplied junction box.
2. Fasten the fl exible conduit from the SWG Venter into the
conduit connector. Mount the CK-91FV junction box or installer
supplied junction box onto the wall or fl oor joist without
straining the fl exible conduit. Fasten the CK-91FV junction box
through the four dimpled locations on the base of the box.
(See Figure 3)

PRESSURE SWITCH SENSING TUBE INSTALLATION

1. Attach the ⁄ " tubing connector to the pressure tube on the
1
4
SWG Venter. (See Figure 3)
2. Connect the supplied
connector. Route the tubing to the CK-91FV junction box and
connect the tubing to the pressure switch. When routing the
tubing, avoid kinking the tubing by bending the tubing too
sharply.
For remote mounted CK-91FV Junction Box, use a
aluminum or plastic tubing and route the tubing to avoid contact
with any heat source.

DRAFT CONTROL INSTALLATION

CAUTION: This draft control is shipped as a single acting draft
control. If the draft control is not being used on a gas draft induced
furnace, remove the gate stop on the draft control ring before
installing.
