1. The fireplace may be installed in and vented through
any solid fuel fireplace that has a minimum fireplace
opening 25¹⁄₄"W x 17¹⁄₂" H x 13¹⁄₂"D for LHEC20 and
LHER20 or 28³⁄₄"W x 21"H x 15¹⁄₂"D for LHEC30 and
has been installed in accordance with the National,
Provincial/State and local building codes and is
constructed of noncombustible materials.
2. In order to gain minimum gas insert fireplace
opening requirement, if the fire brick refractory is
FP1331
removed from a factory built fireplace, a minimum of
1/4" air space is required between the gas insert
fireplace's outer casing and the inner wall of the
factory built fireplace.
3. In order to obtain the best performance, safety and
efficiency for the gas insert fireplace, the LHEC30
gas insert must be installed with an approved 4"
diameter flue liner. The LHER20 and LHEC20
should be installed with an approved 3" diameter flue
liner as per current CSA-B149.1 or National Fuel
Gas Code ANSI Z223.1.
4. Any flue damper must be removed or blocked open.
5. The chimney must be clean 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 appliance without trim frame and make all
gas fittings and electrical connections.
8. Install the decorative trim frame. Please refer to the
Frame Assembly instructions.
Installer must attach red warning plate
with screws supplied with the gas fire-
place insert to the inside of the firebox of
the fireplace into which the gas fireplace
insert is installed.
Cutting any sheet metal parts of the
fireplace, in which the gas fireplace insert
is to be installed, is prohibited.
If the factory-built fireplace has no gas
access hole(s) provided, an access hole
of 1.5 inch (37.5mm) or less may be
drilled through the lower sides or bottom
of the firebox in a proper workmanship-
like manner. This access hole must be
plugged with a noncombustible insula-
tion after the gas supply line has been
installed.
Some factory-built fireplaces have air passages
on face of fireplace for zero clearance capabilities.
Under no circumstances should these passages
be blocked.
