Wells with a spud setscrew are designed for use with 

controllers that have armored capillary with a brass collar at 

the bulb end of the armor. The setscrew tightens against the 

brass collar. See Fig. 7. These wells can be adapted for use 

with 5/64 in. capillary by adding the 124904 Well Adapter and 

the 121371 Mounting Clamp Assembly. See Fig. 3.

1. Coat external spud threads with a moderate amount of 

pipe dope, leaving two end threads bare. See Fig. 4.

NOTE: Teflon tape can also be used.

2. Screw the spud into the tapping and tighten securely.

3. Place the packing nut on the tubing.

4. Slide the bulb completely through the fitting.

5. Place the composition disk and the four slotted brass 

washers on the tubing in the order shown in Fig. 8.

6. Turn the brass washers so that the slots are 180 degrees 

apart and the small tabs are in the mating slots.

7. Slide the seal assembly into the fitting. Make sure the 

sensing bulb extends the desired distance into the 

controlled medium. See Fig. 2.

8. Tighten the packing nut.

Use element holders to mount air temperature sensors in a 

duct. Locate the sensing element where air at representative 

temperatures can circulate around it. In a plenum application, 

locate the element far enough from the combustion chamber to 

avoid the effect of direct radiation.

1. Cut a hole large enough to admit the bulb and holder in 

the duct or plenum at the mounting location.

2. Drill holes for the bulb holder mounting screws.

3. Mount the bulb and capillary on the holder. See Fig. 9 

through 11.

Use these bulb holders to mount one bulb in a duct or plenum. 

See Fig. 9 and 10. If necessary, shorten holders by using pliers 

to flex the channel at one of the notches until it separates.

Use this bulb holder to mount one or two bulbs in a duct where 

temperatures do not exceed 100°F (38°C). The removable 

plug in the mounting plate allows insertion of a thermometer to 

check duct air temperature. See Fig. 11 for installation details.
