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 10 mm thick) are designed to contact the non-com

bustible 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 above.

Note: Refer to Section 10 for important information

related to facing, drywall specifications and decorative

front information.

* Adjust framing dimensions for interior chase sheathing (such as sheetrock)

** If appliance is installed off of floor, maintain required clearances to combustibles. Construct platform in accordance with local building codes.

Framing should be done in a manner similar to framing a

window or door: double - 2 x 4 / 2 x 6 (90 x 35 mm for AU)

as a Header for horizontal strength and untilizing Jack

or Trimmer Stud fastened to the King Studs for vertical

strength.

If elevating the appliance, the base of the unit should also

be constructed in a similar manner to prevent settling.
