Heat & Glo Fireplace Heat & Glo Fireplace AT-GRAND - Manual (Page 9)

A vertical vent termination system installed on this
model will include one (1) length of 3-inch flexible vent
pipe for the combustion air, one (1) pipe-to-cap
adaptor, and one (1) SLK-991DA or SLK-980D Vertical
termination Cap.
NOTE: The damper of the masonry chimney may
need to be removed to allow installation of the flexible-
vent pipe.
This fireplace has been altered to accommodate an
insert and should be inspected by a qualified person
prior to re-use as a conventional fireplace.
NOTE: The above label, located in the instruction
package, must be affixed to the existing fireplace prior
to installation of Model AT-GRAND.
For zero clearance, factory built woodburning
fireplaces, the use of kit LINK-ZC-ADP, in place of the
standard square flashing, will allow you to mount the
adaptor and cap on metal pipe. Additionally, the use of
kit FLASH-DAMP will seal off the damper opening
when terminating the inlet air vent pipe just above the
damper. These two kits are recommended for zero
clearance, factory built woodburning fireplaces.
Connecting the Vent Pipe
Install the 3-inch flexible vent pipes down through the
chimney. Attach and secure the bottom ends of the
flex pipes to the starting collars on the unit with 3
sheetmetal screws on each collar. Slide the gas insert
into place, and position any excess flex vent pipe back
up into the chimney.
Attach the pipe-to-cap adaptor to the termination cap
and the top of the flexible vent pipe and set the cap in
place at the top of the chimney. See Figures 3, 4 & 5.
TO AVOID DOWNDRAFTS AND/OR COLD AIR
PROBLEMS, IT IS RECOMMENDED TO SEAL
OFF THE AREA BETWEEN THE TERMINATION
CAP AND THE TOP OF THE SOLID-FUEL
CHIMNEY OPENING INTO WHICH THE VENT
CAP HAS BEEN INSTALLED.
When using the LINK-DV4-30 vent system, it is required
to seal around the flexible vent pipes in the damper
area. See Figure 3. Use fiberglass insulation or other
suitable non-combustible material.
