PUREFIRE EMISSION CONTROL SYSTEM

This  fireplace  is  equipped  with  a  PureFire 

Emission  Control  System.  The  Catalytic 

Hood system reduces particulates emissions 

in a wood burning fireplace to meet the EPA 

Wood-Burning  Fireplace  Program  Phase  2 

emission level. 

The EPA qualifying label, shown on page 18, 

will be affixed to the catalyst. Before lighting 

the first fire, remove and maintain this label in 

a safe place if needed for permits or building 

inspection. Prior to beginning installation, con

-

tact your local building official to determine the 

need to obtain a permit. For proper operation, 

catalyst must be replace every 3 to 5 years.

FUELING GUIDELINES

The fireplace grate must always be secured 

to the retaining brackets provided. The posi

-

tion of the grate must be centered against the 

back wall of the firebox.

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. Do 

not use 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 opti

-

mum efficiency when the fireplace is burning 

clean,  dry,  cord  wood  as  fireplace  fuel. A 

simple visual inspection of the chimney dur-

ing the wood burning process will determine 

catalyst performance. 

The  fuel  load  should  always  be  placed  on 

the back of the grate. Use clean dry wood, 

seasoned cord wood is the best choice. 

Never burn trash, plastics, gasoline, rubber, 

industrial solvents, flammable liquids, naptha, 

household garbage, material treated with 

petroleum products, leaves, paper products, 

cardboard or salt driftwood. 

Refer to your FMI PRODUCTS, LLC 

Home-

owner's Guide 

included with your fireplace for 

proper fire building technique and ash removal 

procedures. These fueling guidelines must be 

followed in order to achieve maximum emis-

sions performance from the PureFire System.

OPERATION

The proper use of a wood burning fireplace 

equipped  with  the  catalyst  will  significantly 

reduce the emissions that it produces. Simple 

fuel considerations with regard to moisture 

content, size, and quality of fuel will help 

control the production of wood smoke and 

improve the performance of the catalyst and 

fireplace  efficiency.  With  proper  care,  the 

catalyst 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 cata

-

lyst is a technology that provides secondary 

combustion for the wood burning process. 

MAINTENANCE

The PureFire System is a maintenance free 

technology. Do not attempt to remove or clean 

the combustor. The direct flame from the fire 

will  clean  the  combustor.  Only  a  certified 

technician should remove the unit. To ensure 

proper fireplace operation, the PureFire Sys

-

tem should be replaced every 3 to 5 years 

(see 

Parts

 on page 20). 

NOTE: Chimney smoke may be visible during 

the first 8 to 10 minutes of fireplace operation 

when the fire is first getting started and the 

final 8 to 10 minutes of operation while the fire 

is dissipating. Under normal operating condi

-

tions, you should see little or no smoke coming 

out  of  the  chimney.  If  continuous  smoke  is 

visible, make sure only dry seasoned wood 

is being burned. If visible smoke continues,  

the combustor has ceased to function or there 

is thermal crumbling. Call FMI PRODUCTS, 

LLC at 1-866-328-4537 for replacement parts.
