Framing
This appliance is designed to be recessed into combus-
tible framing with non-combustible material pre-installed
on top and side. Drywall or combustible materials (mini-
mum 1/2 inch thick) are designed to contact the non-
combustible material/appliance as called out in Section
10 Finishing.
This appliance has been thoroughly tested to minimize
drywall cracking and/or the protrusion of screws "screw
pops" when framed as shown below.
Framing should be done in a manner similar to framing a
window or door: Double-2x4/2x6 as a header for horizon-
tal strength and utilizing Jack or Trimmer stud fastened to
the King studs for vertical strength.
Note: Header MUST be installed on end as shown in the diagram.
