a wood or noncombustible continuous flat
surface.
•
Level the appliance from side to side and front
to back.
•
Shim the appliance with noncombustible
material, such as sheet metal, as necessary.
•
Chase platforms, including hearths, should
slope away from the structure at 1/8 inch to
1/4 inch per foot.
•
Nailing tabs must be moved from shipping
position to installation position and secured
to framing. Bend the four nailing tabs out on
each side. See Figure 4.1.
B. Flashing
•
Flash the appliance in a manner consistent
with regional practices to prevent water
penetration around the appliance. Due to
elevated temperatures across the top of the
appliance, metal flashing and high temperature
sealant must be used. Adhesive polymers
flashing materials may melt.
•
For
brick,
stone,
construction, weep screeds should be installed
per regional codes.
•
See Section 3.F. and Figures 3.2. for more
