OPERATING THE BRENTWOOD
Fuel
USE SOLID NATURAL WOOD FUEL ONLY.
The Brentwood 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 usu-
ally 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.
WARNING
Be careful adding wood fuel to the
fire or handling fireplace tools such
as shovels, tongs or pokers.
WARNING
The bottom refractory can be
cracked by excessive abuse such
as tossing heavy logs onto the
grate or gouging with fireplace
tools. Exercise caution when
adding wood to your fireplace.
