K Factors of Alternate Materials:
Material K Required Thickness
Ceroform 126 .21 1/8"
Limestone 8.0 3.2"
Concrete 8.0 3.2"
Sandstone 13.0 5.2"
Marble 18.0 7.2"
Hearth extension or floor protector thickness above four (4) inches is generally not acceptable due to cost, floor
load capacity, and look. The alternate we recommend is using Ceroform No. 126 millboard 1/8" thick minimum
and putting any type decorative brick or stone (any thickness) on top of it.
*The K* factor represents the thermal conductivity of a material and is the time rate of heat flow through a
homogeneous material under steady-state conditions, through unit area, per unit temperature gradient in the
direction perpendicular to a surface.
9. The next step is the electrical installation. NOTE: An electrician must wire the 51ZC into the home wiring
system using No. 15 AWG (with ground wiring) as minimum in accordance with local wiring codes.
CAUTION: Stove is plugged into cabinet receptacle.
A. Remove brass trim.

9. Finish the wall around the 51ZC using brick, rock, sheetrock, paneling, or any type finishing material.
CAUTION: Do not block any openings designed into the unit.
10. Install a mantel above the unit, if desired. Note that a combustible mantel must be positioned at least 30 1/2"
above the top of the stove.
11. The 51ZC and Model 51,T51,74 or T-74 fireplace are now ready for use. Refer to the stove owners manual for
