The junction box can be mounted at the venter or remotely 
mounted away from the venter. (See Fig. 1 & Fig. 2) 

1.  Remove one of the knockouts from the side of the junction 

box where the pressure switch is mounted. Install the 
flexible conduit connector onto the CK-50 junction box 
and secure with fastening nut. If remote mounting the CK-
50 junction box, mount the flexible conduit connector onto 
a 2" x 4" installer supplied junction box. 

2.  Fasten the flexible conduit from the SWG Venter into the conduit 

connector. Mount the CK-50 junction box or installer supplied junction 
box onto the wall or floor joist without straining the flexible conduit. 
Fasten the CK-50 junction box through the four dimpled locations on 
the base of the box. (See Fig. 3)

NSTALLATION

1.  Attach the 1/4 inch tubing connector to the pressure tube on 

the SWG Venter. (See Fig. 3) 

2.  Connect the supplied 1/4" aluminum tubing to the tubing 

connector. Route the tubing to the CK-50 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-50 Junction Box, use a 1/4" OD copper, 
aluminum or plastic tubing and route the tubing to avoid contact 
with any heat source.

After proper air flow is established, the pressure switch adjustment is 
made by turning the pressure switch adjustment screw clockwise 
(See Fig. 4) until burner operation stops. Turn the adjustment screw 
counterclockwise until burner ignites. Turn the adjustment screw an 
additional 1/4 to 3/4 turn counterclockwise to ensure adequate switch 
adjustment. 

WARNING: 

Failure to properly adjust the pressure switch as 

specified above could lead to improper operation of the 
pressure switch which will result in a hazardous condition and 
bodily harm!
