Notes
Due to Lennox' ongoing commitment
to quality, all specifications, ratings
and dimensions are subject to change
without notice.
All framing dimensions calculated for
1/2" dry wall at the fireplace face. If
sheathing the chase or finishing with
other thickness materials, calculations
will need to be made.
* The fireplace must not be in contact with
any insulation or loose filling material.
Cover the insulation with Drywall panels
around the fireplace.
Combustible materials can NOT be
used in the space directly above the
fireplace. Do not fill the space above
the fireplace with any material (Except
the wood framing)
