throughout this installation is critical to the operation of the balanced flue system. A tube of
caulking is provided with the installation kit. This tube should be sufficient for the whole
installation, but if more caulking is needed buy one of the following: GE 106, Dow Corning 736
Heat Resistant Sealant, Perimeter 248 High Temp or RTV Silicone Gasket.
Follow these steps to obtain a good seal.
Boiler
A. Seal the 6” smoke collar to the smoke hood on the boiler with the high temperature
silicone. Inspect all boiler openings (sight door, burner connection, pipe joints, Etc) during
initial operation, to verify that there are no leaks.
Flex Pipe
Make sure that it’s long enough to form long radius bends (no smaller than 1 ft in radius). If the
flex is too long, it can be cut with a hacksaw.
It is recommended to remove the collar on the 81098 & 81112 flex adapters that secures
the insulation and outer foil of the Flex pipe. This can be accomplished by removing the
pop rivet at the base of the collar, and backing off the gear clamp completely. After
removing the collar, you will get a perfect unobstructed view of the pipe joint. To
reinstall, put the collar back into place and install a #8x½” screw in rivet hole, and re-
thread the gear clamp.
B. Pull the outer foil sheathing and insulation back as far as possible, to give an unobstructed
view of the pipe joints. Put 1 bead of silicone on both inside ends of the insulated flex pipe,
approximately 1” wide and ½” from the end. Put 1 bead of silicone on both outside ends of
81098 & 81112 connectors, approximately 1” wide and 1” from the bottom of the threads.
Screw in part number 81089 & 81112 adapters into the insulated flex and pull the
insulation and the outside flex over the collar and tighten the gear clamp.
C. Apply a wide bead on top of the flex joint.
D. Reinstall the collars on the vent connectors using a #8x½” screw in rivet hole, and re-
thread the gear clamp
E. Apply silicone between the vertical overlap joint of the 6-3” adapter.
F. Apply silicone on inside surface of the 6-3” adapter
G. Apply silicone on outside surface of the smoke hood collar, and slide 6-3” adapter over the
smoke hood and tighten the gear clamp.
H. Perform steps D-G to install the 3” adapter #81098 over the 3” pipe of vent terminal, and
tighten gear clamp.
I. Fold the vent terminal heat shield flaps back into position.
NOTE: - It’s the installer’s responsibility to ensure that the combustion products do not enter
the home.
6.0 CLEANING
Do not remove the 6” to 3” adapter from the breech or any of the other exhaust connections for
cleaning the Caprice. Remove the top jacket panel and the flue cover with the adapter still
attach to it. Follow the typical boiler cleaning routine. To reattach the smoke hood, install ½”
ceramic rope under the smoke hood flange.
