THE FIREPLACE
INTRODUCTION
The Brentwood wood-burning fireplace is an
energy efficient, heat circulating, closed com-
bustion fireplace. You will receive a lifetime
of comfort and enjoyment from your fireplace
provided it is installed, maintained and oper-
ated properly.
• Please read these instructions and retain
this manual for future reference.
• Before beginning the fireplace installation,
consult the local authorities to obtain your
building permit and check your local building
codes. Install the fireplace only as described
in these instructions and using only Lennox
Hearth Products components.
• The Brentwood fireplace is not intended for
use with a gas log set. Do not use a fireplace
insert or any other product with this fireplace
unless it is specified by Lennox for use with this
appliance. Failure to follow these instructions
will void the certification and the warranty of

They are not intended for continuous use as
a primary heat source.

OPERATING THE BRENTWOOD FIRE-
PLACE
Fuel
USE SOLID NATURAL WOOD FUEL ONLY. The
Brentwood fireplace is designed to work best
when fueled with dry seasoned natural wood
only. Hardwoods are preferred to softwoods
since the energy content of wood is relative to
its density. Hardwoods will result in a longer
burning fire and less frequent refueling. A
moisture content of 15% to 20% (seasoned)
is recommended. Wood that has been cut and
split and let to dry under a cover for a period
of one year will usually meet that criteria.
Excessively wet wood will be difficult to burn
and will result in lower efficiency, increased
creosoting and deposits on the glass and in
the chimney. Excessively dry wood will burn
well but will also have higher emissions and
shorter burning time.
Do not burn scrap or garbage, treated wood or
wood such as driftwood from the ocean which
has been exposed to salt or other chemicals.
Salt or chemicals can corrode the firebox and
chimney. Do not burn large amounts of paper,
cardboard, Christmas tree branches or build-
ing construction materials. Intense firing with
these materials may overheat the fireplace,
causing damage to the unit, a fire or even
possibly igniting a chimney fire if the chimney
is creosoted.
First Fires
Before using the fireplace make sure to re-
move the plastic wrapping and EPA label on
the door. Remove any glue residue left by the
label using mild soap.
The first five or six fires should be small fires of
short duration (about 30 to 60 minutes). This
will help cure the refractory bricks. The first
fires may produce slight smoking and some
odor due to curing of the paint and steel and
the burning off of dust accumulated on the
fireplace will burn off at this time. It may set off
a smoke alarm located in the same room. For
this reason the room should be well ventilated
for the first few fires.

special attention to the safety instructions provided in this manual. This information
will be useful to you now and in years to come, so keep the manual handy and refer to
it as needed.
