PureFire™ Fireplace Technology
The PureFire™ Emission Control Technology from Clear Skies Unlimited is a catalytic system designed
especially for wood burning fireplaces. The PureFire™ utilizes a patented smoke hood to capture the
pollutants from the fire allowing most of the dilution air to bypass the hood and exit through the flue
system. The PureFire™ Combustor provides a secondary ignition for the wood smoke combustibles
preventing them from leaving the firebox as particulate pollution. The direct flame on the catalytic
surface actually cleans the catalytic unit.
The PureFire™ hood is manufactured from high quality stainless steel. The catalytic component is a
state-of-the-art ceramic material designed to operate in the direct flame of a fireplace.
The PureFire™ is equipped with (2) sets of mounting brackets to attach the hood assembly onto the
wall of the firebox. The flat brackets are designed for factory built fireplaces while the other brackets
should be used on factory built “metal box” fireplaces. The mounting hardware is designed with a lip
on the front to prevent the PureFire from moving. The attachment brackets will suspend the
PureFire™ above the grate. The mounting screws will securely attach the hood to the sides of the
firebox.
PureFire™ Operation
The PureFire™ Wood Burning Fireplace Emission Control System is positioned directly above the grate
against the back of the firebox.
The damper handle will extend downward in the center of the PureFire™. The fireplace damper
remains fully operational. The opening between the PureFire™ Combustor blocks will allow the
damper handle to move freely “back-and-forth”.

CAUTION
…………………
The damper must be in the open position at all times when the fireplace is in use. Never burn
a fire with the damper closed!
