Heat & Glo LifeStyle AT-GRAND manual Connecting the Vent Pipe, To Avoid Downdrafts And/Or Cold Air

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.
CAUTION	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.
