replace to a wall, or any combustible materials, and 10" clearance from the top
of the replace to the underside of any combustible shelf materials.
• For top vent applications, the minimum clearance is 2" from the rear of the
replace to a wall, or any combustible materials, and 21" to the underside of
any combustible shelf materials.
Minimum 2" clearance must still be maintained around the vent pipes.
