VENTING AND INSTALLATION
1. Heat -N-Glo gas inserts are designed for recessed installations into solid fuel
Masonry or Factory Built Non Combustible fireplaces that have been installed
in accordance with the National, Provincial, State and local building codes.
2. Minimum fireplace opening requirements are shown in Figure 1 of this instal-
lation manual. The firebrick (refactory) can be removed from a factory built
fireplace in order to gain minimum gas insert opening requirements.
3. To assure top performance, safety and efficiency, inserts must be installed
with an approved flue liner as per CAN/CGA B-149 or National Fuel Code
ANSI Z223 and these instructions.
WARNING
THE SOLID FUEL FIREPLACE HAS BEEN CONVERTED FOR USE
WITH GAS ONLY AND CANNOT BE USED FOR BURNING WOOD
OR SOLID FUELS UNLESS ALL ORIGINAL PARTS HAVE BEEN
REPLACED AND THE FIREPLACE HAS BEEN REAPPROVED BY
THE AUTHORITY HAVING JURISDICTION.
4. The solid fuel fireplace’s flue damper must be fully locked in the open position
or removed for installation.
5. The chimney must be cleaned and in good working order and constructed of
noncombustible materials.
6. Make sure that all chimney cleanouts fit properly so air cannot leak into the
chimney.
7. Install the insert without the trim surround and make all gas, venting, and
electrical connections.
WARNING
Under no circumstances cutting of sheet metal surfaces are al-
lowed for installation.
If the factory built fireplace has no gas access holes provided, an
access hole of 1” diameter (25mm) or less may be drilled through
the lower sides or bottom of the combustion chamber in a proper
workmanship like manner.
8. Install decorative trim surround. Please refer to instructions included with the
trim surround.

WARNING
THIS GAS INSERT AND VENT
ASSEMBLY MUST BE VENTED
DIRECTLY TO THE OUTSIDE AND
MUST NEVER BE ATTACHED TO A
CHIMNEY SERVING A SEPARATE
SOLID FUEL BURNING APPLIANCE.
EACH GAS APPLIANCE MUST USE A
SEPARATE VENT SYSTEM. COMMON
VENT SYSTEMS ARE PROHIBITED.
Installing the
Insert
Vent System Approvals
Table 1 and Figure 3 through 5 shows the vent
termination caps and systems approved for the use
with these models. Approved vent system
terminations are labeled for identification. 3-inch
diameter listed flexible aluminum or stainless steel
gas vent is used for both the incoming combustion air
and exhaust vent pipes. NO OTHER VENTING
SYSTEMS OR COMPONENTS MAY BE USED.
Detailed installation instructions are included with
each vent termination kit and should be used in
conjunction with this manual.
Horizontal Venting
The vent system on this model CANNOT be
terminated horizontally.
Vertical Venting
The vent pipes MUST be connected to the proper
collars on the unit AND the exhaust vent pipe MUST
be connected to the termination cap or the unit will not
operate. The combustion air vent pipe CAN be
connected to the termination cap or it can terminate
inside the chimney. The bottom opening of the
chimney must be sealed around the vent pipes if the
combustion air vent is NOT connected to the
termination cap. See Figures 3, 4 and 5.
NOTE: The minimum vertical rise (exhaust vent) is
14 feet and the maximum vertical rise is 50 feet.
These dimensions are measured from the starting
collars of the unit to the end of the last section of vent
pipe See dimension V in Figure 3.

Download from Www.Somanuals.com. All Manuals Search And Download.
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-991DAor 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 BAY-INS.
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.
NOTE: Optional ZC-ADP Kit can be attached to the
top of the unit and will increase the depth of the unit’s
starting collars if needed. See Figures 4 and 5.
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.
