7. The ZC20 cabinet is now ready for framing as follows:
a) Frame the ZC20 using 2”x4” studs or local building code framing. Some minor framing restrictions are
required:
1. Adjacent side walls must be at least 16” from the outer edge of the ZC20 trim panel
2. The overall opening dimensions must be at least 37 15/16” wide and 34 5/8” high.
NOTE: Maintain 1 1/2” clearance at the side walls of the cabinet and combustible material.
b) 2”x4” framing above the unit must be turned flat. This allows proper clearance from framing to chimney
(2” minimum). (See Figure 6.)
