OPERATING THE FIREPLACE
Fuel - USE SOLID NATURAL WOOD FUEL
ONLY. The Cambria fireplace is designed to
work best when fueled with seasoned cordwood.
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 refuelling. 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.
Processed firelogs can be used. Although, do
not poke or stir the logs while they are burning.
Use only firelogs that have been evaluated for
the application of fireplace and refer to firelog
warnings and caution markings on packaging
prior to use.
