Testing Information
This manual describes the installation and operation of the Per-
former™ S210 non-catalytic wood heaters. These heaters meet
the U.S. Environmental Protection Agency’s emissions limits for
wood heaters sold on or after July 1, 1990. This heater has been
developed, tested and constructed in accordance with the require-
ments of UL 1482, ULC S627 and HUD standards and is listed by
OMNI Test Laboratories, Beaverton, OR. It has been approved for
residential, mobile home and alcove installations.
Draft Requirements
Your wood stove is dependent upon a properly functioning chimney
for optimum performance. It is a high efficiency appliance that
loses much less heat up the chimney than older appliances and
fireplaces. For this reason it is important to match the stove to
the chimney. The chimney has two functions:
1. It draws combustion air into the appliance (without air, no fuel
will burn) and
2. It exhausts combustion by-products. Your new Country™ Col-
lection stove is what is known as a “natural draft” appliance.
The appliance depends solely on the natural draft of the chimney
system to draw combustion air into the unit. Draft is the force that
moves air from the appliance up into the chimney. The amount of
draft in your chimney depends on the length of the chimney, local
geography, nearby obstructions and other factors. Too much draft
may cause excessive temperatures in the appliance (overfiring).
Slow or inadequate draft equals poor combustion and possible
smoking problems. The following are some conditions that may
contribute to poor chimney draft:
1. A chimney too large for your appliance.
2. A chimney with not enough height to produce adequate
draft.
3. A chimney with excessive height (this may allow exhaust
to cool too much before exiting, which will stall the rate the
exhaust exits).
4. Offsets in the venting system are too restrictive (see Chimney
Guidelines).
Inadequate draft will cause the appliance to leak smoke into the
room through the stove and the chimney connector joints.
Excessive draft may cause an uncontrollable burn or a glowing
red stove or chimney part.
Overfiring Damage - If the heater or chimney connector glows,
you are overfiring. Other symptoms may include: Cracking,
warping or burning out of components, plated doors may turn
color, stove glass may develop a haze, which will not come off
with cleaning.
Overfiring of a stove is a condition where excessive temperatures
are reached, beyond the design capabilities of the appliance. The
damage that occurs from overfiring is not covered under the
manufacturer’s limited warranty.

Selecting the Proper Venting System
The appliance is merely one component of a larger system. The
other equally important component is the venting system. This is
necessary for achieving the required flow of combustion air to the
fire chamber and for safely removing unwanted combustion byprod-
ucts from the appliance. If the venting system’s design does not
promote these ends, the system may not function properly. Poorly
functioning venting systems may create performance problems as
well as be a safety hazard. A draft test should read greater than
.04’ W.C. (inches water column) and less than .08” W.C. As
per NFPA-211 standard (see paragraph below), the installer must
take into account all variables within the installation and install the
appliance in such a manner that satisfies the draft requirements
of the appliance. See Chimney Guidelines below to assist you in
selecting the proper venting system for your installation.
American National Standards Institute ANSI/NFPA 211, Standard
for Chimneys, Fireplaces, Vents, and Solid Fuel-Burning Appli-
ances - See Draft Section: A chimney or vent shall be so designed
and constructed to develop a flow sufficient to completely remove all
flue and vent gases to the outside atmosphere. The venting system
shall satisfy the draft requirements of the connected appliance in
accordance with the manufacturer’s instructions.
Chimney Guidelines:
• This appliance requires approximately 12 feet minimum of
“effective draw” provided by the venting system. As a rule of
thumb, every 90 degree total direction change in the venting
will result in a loss of approximately 5 feet of “effective draw.”
Example: If two 45 degree offsets are used, subtract 5 feet
from the actual vertical vent height to determine your “effec-
tive draw.” In this case if you had 14 feet of vertical vent, the
effective draw would only be approximately 9 feet (14 ft. - 5 ft.
= 9 ft.), therefore it may be necessary to add additional height
to the venting system.
• Do not install an offset within the first two feet above the flue
outlet on the appliance.
• In well insulated and weather tight homes, it may be difficult
to establish a good draft up your chimney. The poor draft is
caused by a shortage of air in the house. In this situation an
Outside Air Kit may need to be installed (See Negative Pressure
Warning on Page 5 and Outside Combustion Air on Page 8).
