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.
Ensure there are no obstructions to side air passages of decora-
tive trim once installed on insert.
