Mantels

When the unit is installed into a woodburning fireplace, the minimum distance the mantel can be placed above the fireplace is governed by local building codes appli- cable to woodburning fireplaces. Consult local authori- ties having jurisdiction for these clearances.

For applications requiring the use of a Zero Clearance Kit, the minimum height a mantel can be installed above the fireplace is 24" (610mm) from the top of the upper louvres. The maximum mantel depth is 8" (200mm). (Fig. 2)

The underside of the mantel will become warm. Use only finishes which are heat resistant and do not discolor.

Framing & Finishing

For Zero Clearance Kit applications, it is important to determine the finished facing material before beginning to frame. This will allow for the thickness of the finishing material between the frame and the fireplace trim.

Similarly, consideration must be given to the 1" inch depth of the air inlet channel sitting on the fireplace base. Finishing material for the hearth should be flush with the top of the air inlet channel.

If the fireplace is installed at floor level a noncombus- tible hearth must extend a minimum 12" (305mm) in front of the fireplace.

If the fireplace is recessed into the wall and at least 12" (305mm) above floor level, no hearth is required.

The use of wallpaper adjacent to this fire- place is not recommended as high tem- peratures given off by this fireplace may adversely effect the binders in the adhe- sive used to apply the wallpaper.

Zero Clearance Applications

An alternate air supply is recommended with this component.

For installation other than in existing wood- burning fireplaces such as new construction or renova- tion projects, a Zero Clearance Kit must be used. The kit enables these inserts to be installed in combustible environments. Whenever using a Zero Clearance Kit, consideration must be given to the dimensions of the Zero Clearance Kit and the requirements of the Air Kit.

NOTE: If a Zero Clearance Kit is required for mod- els LHEC20/LHER20/LHEC30/LHER30 Natural Vent Inserts, only the CFM Corporation zero clearance kit HEZC is approved to be used. When using the HEZC with insert models LHEC20 or LHER20, the Trim Closure Kit, LHE20TCK, must also be installed.
