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 26).

Installing Firebox Facing
Any noncombustible material may be used for facing (glass, tile, brick, etc.) as long as proper clearances are adhered to and firebox openings are not obstructed in any way (see Figure 27).
Use only heat resistant, noncombustible mortar or adhesive when securing facing material to front of firebox. When placing facing at upper edge of effective opening of firebox, provide “L” shaped piece of metal extending full width of opening (see Figure 27).
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.
