Venting Installation

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 (641 x 438 x 343 mm) for LHEC20 and LHER20 or 28³⁄₄"W x 21"H

x 15¹⁄₂"D (730 x 533 x 394 mm) for LHEC30 and LHER30 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 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 and LHER30 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/NFPA 54.

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 fireplace 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 fire- place, 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 1¹⁄₂ (37.5 mm) or less may be drilled through the lower sides or bottom of the firebox in a proper workmanship-like man- ner. This access hole must be plugged with a noncombustible insulation after the gas supply line has been installed.

WARNING

Some factory-built fireplaces have air passages on face of fireplace for zero clearance capabilities. Under no circumstances should these passages be blocked.
