Chase installations
Instructions for chase installations are included with the chase style termination chosen. In a multiple chase installation, be sure to provide adequate distance between terminations to prevent smoke spillage from one termination to another. Terminations must be separated a minimum of 30" center to center and stacked at a minimum vertical height difference of 18" (see Figure 27).
Note: If a decorative shroud is to be installed, contact the manufacturer for specifications.

finishing fireplace
Combustible materials, such as wallboard, gypsum board, sheet rock, drywall, plywood, etc. may make direct contact with sides and top around the fireplace face. It is important that combustible materials do not overlap the face itself. Brick, glass, tile or other noncom- bustible materials may overlap the front face provided they do not obstruct essential openings like louvered slots or any other opening. When overlapping with a noncombustible facing material, use only noncombustible mortar or adhesive.
Installing fireplace facing
Any noncombustible material may be used for facing (glass, tile, brick, etc.) as long as proper clearances are adhered to and fireplace openings are not obstructed in any way (see Minimum Clearance to Combustibles, page 4 and Figure 28).
Use only heat resistant, noncombustible mortar or adhesive when securing facing material to front of fireplace. When placing facing at upper edge of effective opening of fireplace, provide “L” shaped piece of metal extending full width of opening (see Figure 28).
Secure with sheet metal screws at a distance high enough from edge so it doesn't interfere with operation of doors. This assures that facing material will not block openings.
