Venting and Installation

WARNING

This 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 re-approved by the authority having jurisdiction.

Cutting any sheet metal parts of the fire- place, in which the gas fireplace insert is to be installed, is prohibited.

Ensure there are no obstructions to side air passages of decorative trim once in- stalled on insert.

WARNING

Some factory built fireplaces have air passages on face of fireplace for zero clearance capabili- ties. All trim kits are designed so as to allow air- flow to these passages. Under no circumstances should these passages be blocked.

1.Gas inserts are designed for recessed installations into solid fuel masonry or factory built noncombustible fireplaces that have been installed in accordance with the National, Provincial, State and local building codes.

2.Measure for minimum fireplace opening requirement on Page 4 of this installation manual. (If firebrick [refractory] is removed from a factory built fireplace in order to gain minimum gas fireplace insert opening requirements, a minimum of 1/4" (6 mm) air space is required between the gas insert fireplace's outer casing and the inner wall of the factory built fireplace).

3.To assure top performance, safety and efficiency, all inserts must be installed with an approved 4" diameter flue liner, with exception of A125, which should be installed with an approved 3" liner,as per CSA-B.149 or National Fuel Code ANSI Z223/NFPA 54.

4.Flue damper must be fully blocked in the open position or removed for installation.

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.Glass door, screen kits and log grate may be removed for installation of insert into factory built fireplace.

8.Install the insert without the trim frame and make all gas, venting and electrical connections.

9.Install decorative trim frame. Please refer to Frame Assembly and Mounting instructions In this manual.
