Introduction to the PureFire Technology
Congratulations! You have purchased a “State-of-the-Art” EPA Phase II Qualified Emission Control
Device for wood burning Fireplaces.
The PureFire™ Emission Control Technology from FMI Products LLC is a catalytic system designed
especially for wood burning fireplaces. 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
primary flue system. The PureFire™Catalytic Combustor provides 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™Unit is equipped with mounting hardware to install the hood assembly into the fireplace.
The mounting hardware is designed with a “Hook Shaped” bracket that attaches to the damper opening.
The attachment brackets will suspend the PureFire™ above the grate.
The PureFire™Installation
The PureFire™Wood Burning Fireplace Emission
Control System is positioned directly above the
grate against the back of the firebox.
The damper handle for masonry fireplaces will
extend downward in the center of the PureFire™
device. When PureFire is properly installed, 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!
Maintenance & Catalyst Replacement
The PureFire™Wood Burning Fireplace System does NOT require any maintenance. It utilizes a “self-
cleaning” catalytic component. The only time you should remove the catalytic component is for
replacement purposes. There are four (4) screws holding the catalytic block in the PureFire™hood. Once
the screws are removed, the catalytic block is easily removed. New screws are provided with the
replacement catalyst.

PureFire Installation
The PureFire™ can easily be installed in a factory built fireplace in less than an hour. Four mounting
screws will hold the two brackets in place. Then the PureFire™ is simply positioned on the mounting
brackets. It’s that simple. Just follow the directions as specified below:
1. The PureFire™ Hood is has a trapezoidal shape to fit the angular sides of the firebox. The hood is
equipped with adjustable extensions that slide-in-and-out. The retro-fit devices can be adjusted for
firebox back wall widths.
2. The PureFire™ should be installed after the fireplace is completely built. It is designed to be
installed as an add-on device. It is mounted on two brackets that are mechanically attached to the side
walls of the firebox. Insure that the firebox is structurally sound before beginning the PureFire™
installation. The brackets will be mounted on the sides of the firebox using the (4) factory built screws
(provided). It is very important to install the brackets in the proper location in the firebox as described in
STEP # 3.
3. The two stainless steel brackets should be attached to the firebrick on the side walls with the
ends touching the back wall as shown in the diagram on the left. The height of the bracket installation is
determined by the fireplace opening. The brackets should be installed so that they are even with the
height of the fireplace opening (lintel). The brackets can be used to identify location of the mounting
screw holes. A black felt tip can be used to mark the location for drilling. There will be two holes drilled
on each side of the firebox. The firebrick is easily drilled with a 3/16” factory built carbide drill bit. Drill
the holes to a depth of 1”. A suitable hand tool should be used to attach the brackets to the sides of
firebox. Insure that the brackets are installed as shown on right. There is a lip on the bracket that
supports the PureFire™ Hood. The open end of the bracket should be facing the back of the firebox
while the closed end faces the front. The closed end of the bracket will prevent the PureFire™ from
moving after installation.
4. After the brackets are installed, the PureFire™ hood should be adjusted to the right dimension
to properly fit into the brackets. Measure the distance between the installed brackets at their widest
point (front). Now, move the adjustable extensions on the hood until the widest dimension on the hood
extensions equals the widest dimension of the mounting brackets. The extensions should be extended
equally on each side. Now, tighten the retention screws on each side of the hood.
5. The PureFire™ can now be installed in the firebox. Position the device in the brackets so that the
PureFire™ is securely in place. The closed end of the brackets will prevent the PureFire™ from moving
forward in the firebox. The PureFire™ should be located against the back wall of the firebox directly
above the grate. The damper handle (if required) should pass through the opening between the
combustor blocks and remain operational. Chain operated units will have the chain in front of the hood.

PureFire Operation
The PureFire™ Emission Control System for Wood Burning Fireplaces is an add-on catalytic device that
reduces particulate pollution and smoke from wood burning fireplaces up to 80%. It is a passive
technology that doesn’t require any power. The unit operates maintenance free and is not visible to
the homeowner.
The PureFire™for Factory built Fireplaces
Proper use of a wood burning fireplace equipped with the PureFire™is important to insure maximum
pollution reduction. Simple fuel considerations with regard to moisture content, size, and quality of
wood fuel will help control the wood smoke and ultimately improve the performance of the catalyst
and the fireplace. With proper care, the unit will provide years of fuel savings and lowered emissions.
By following some simple guidelines, you will ensure maximum performance and longevity. The smoke
that is usually seen coming out of a chimney is essentially a combination of unburned fuel (carbon and
hydrogen) and moisture in the form of water vapor. The catalyst is a technology that provides
secondary combustion for the wood burning process.
Burn Clean Dry Firewood Only
Burn only dry, seasoned (cured) wood with less than 20% moisture. Avoid the use of treated, painted
and laminated wood. Never burn garbage or other foreign materials. Avoid artificial logs, colored
newspaper or petroleum based fire starters. Avoid wood with high salt content. All of these materials
may contain compounds which can shorten the life of the catalyst. Wet or unseasoned wood may
lower catalytic temperatures and result in inefficient operation. The catalyst is designed to function at
optimum efficiency when the fireplace is burning clean, dry cordwood as fireplace fuel. A simple visual
inspection of the outside chimney for smoke during the wood burning process will determine catalyst
performance.
NOTE: Chimney smoke may be visible during the first 8-10 minutes of fireplace operation when the fire
is first started and also during the final 8-10 minutes of operation when the fire is dissipating. Under
normal operating conditions, you should see little or no smoke coming out the chimney. If a
continuous plume is visible from the chimney, make sure you are burning only dry seasoned wood
(<20% moisture content). In most cases, a visible plume is the result of high moisture content in the
firewood.
Fireplace Damper
If your fireplace is equipped with a “flapper” style damper with an operating handle that extends
downward into the upper chamber of the firebox, the PureFire™is designed to slide over the damper
handle and attach to the damper opening. The damper handle will pass through the center of the
PureFire™device when the device is installed. Two additional ¼” mounting bolts can anchor the
PureFire™more securely to the back wall of the fireplace.
