Combustible mantle clearance can vary according to the
mantle depth. Use the graph to help evaluate the clear-
ance needed. The three-sided top extension piece may be
removed if non-combustible framing is faced with a non-
combustible material.
Dashed lines are suit-
able mantle sizes and
clearances when a
non-combustible fac-
ing is used.

TOP EXTENTION
* The top extension may be removed if non-combustible
framing is faced with a non-combustible material placed
flush with the front face of the unit and extending from the
top of the unit. (Example: cement board) (not supplied).
Combustible counter / bar tops must maintain a minimum
of 38 inches from the base of the fireplace to the underside
of the top.
NOTE: Wolf Steel trim and/or surround kits will not to-
tally cover the top extension of the fireplace. In order to
obtain a smooth transition from the trim / surround to the
wall, it is recommended that the top extension be re-
moved and the unit be installed following the above pro-
cedure.
