T4800 INSTALLATION INSTRUCTIONS
WARNING!
Never install a single wall slip section or smoke-pipe in a chase structure. The higher temperature of this single
wall pipe may radiate sufficient heat to combustible chase materials to cause a fire.
WARNING!
Detailed instructions for installation of the chase top, storm collar and termination cap are packaged with these
parts. To avoid danger of fire, all instructions must be strictly followed, including the provision of air space clearance
between chimney system and enclosure. To protect against the effects of corrosion on those parts exposed to the
weather, we recommend that the chase top and termination cap be painted with a rust-resistant paint.

2. Chase Top
Construct a chase of desired materials maintaining
a minimum 2 air space around the chimney.
3. Termination Cap
a. Install the chimney sections up through the chase
enclosure. When using a TR11 round termination
cap, the uppermost top section of pipe must
extend 6 above the top of the chase collar to allow
installation of the storm collar and termination
cap. See Figure 22.
b. For installations utilizing a TR11T telescoping
round termination cap, the uppermost chimney
section must be below the top of the chase top,
but not more than 14½ below the top of the chase
top flashing collar. See Figure 23.
c. For installations utilizing an ST1175 square
termination cap the last chimney section must
not be more than 4½ below the chase top. See
Figure 24.
d. Attach the chase top to the top of the chase.
e. Install the termination cap, following the
instructions provided with it.
