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.
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
1
⁄
4
" tubing connector to the pressure tube on the
SWG Venter. (See Figure 3)
2. Connect the supplied
1
⁄
4
" aluminum tubing to the tubing
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
1
⁄
4
" OD copper,
aluminum or plastic tubing and route the tubing to avoid contact
with any heat source.
