INTRODUCTION
Your new MODEL FS 21 is a non-catalytic unit designed to meet the most stringent emissions
standards without the use of a catalytic combustor. This effect is achieved through the use of
secondary air which is mixed with primary air in the unit’s firebox.
For peak performance, we suggest the use of hard seasoned natural wood, loading wood
length way from front to rear.
NOTE: Soft woods such as pine, create more creosote, clogging of chimney, and produce a less
efficient burn performance.
You should not burn trash or garbage, artificial or paper logs, gift wrapping, treated or
painted wood or any type of coal.
“DO NOT USE CHEMICALS OR FLUIDS TO START THE FIRE.”
“DO NOT BURN GARBAGE OR FLAMMABLE FLUIDS.”
The primary air, which is controlled by the user, burns the wood. Secondary air is admitted into
the firebox through the secondary air tubes at the top of the firebox. This secondary air burns
the impurities in the smoke released from the initial wood burning. The temperature necessary
for this combustion is maintained through the firebrick refractory. If any more technical
information is necessary, contact your local dealer.
A factory-built prefabricated chimney may be used for your unit when installed in compliance
with the manufacturer's specification and uniform building code.
These units may also be used with optional room air blower. To order the optional motor
assemblies you must specify the stove model number and give one of the following part
number:
*Model 21 Motor Assembly—MA 210715
For operation and use of these electrical assemblies, see instructions provided with the motor
assembly kits.
CAUTION
YOUR CHIMNEY OR FLUE MUST BE CORRECTLY SIZED. A CHIMNEY OR FLUE
THAT IS TOO SMALL OR LARGE IN DIAMETER, OR TOO SHORT, CAN CAUSE
YOUR STOVE TO SPILL SMOKE WHEN THE DOOR IS OPENED.
