* NOTE: Alcove dimensions cannot be reduced by the
use of non-combustible materials such as brick, stone,
etc. Alcove dimensions listed are minimum dimensions
and are not measurements for building an Alcove. You
will need to consider these clearances, as well as
other dimensional requirements before you build the
alcove and install this appliance.

REDUCED MASONRY STRUCTURE CLEARANCE
(ALCOVE)
Your stove can be installed in a masonry structure with
reduced clearances if the structure was built to National
Building Code for fireplaces and chimneys (UBC 37).
The firebox of the masonry structure must be of ade-
quate size to allow a minimum of 6” (152.4 mm) clear-
ance to the sides and top of the stove and 2” (50.8 mm)
clearance to the rear. All stove models must be installed
on their original listed legs or base unless otherwise
specified by OMNI Testing Laboratory.

on their original listed legs or base unless otherwise

The minimum venting requirement is a listed chimney
liner that extends from the flue collar of the stove to the
first tile liner of the chimney where it is sealed. All joints
and connections must be made airtight to prevent leak-
ing and

PROTECTED WALL CLEARANCE
Some local codes will allow reduced clearances when
the stove is installed adjacent to a protected wall system.
Your local building official must approve the variance.
Normally, the protected wall system is defined as a non-
combustible material with a minimum of 1” (25.4 mm) air
space behind. Check your local building codes or with a
qualified installer (Ref. NFPA 211).
