CLEARANCES
WARNING: IT IS VERY IMPORTANT THAT YOU
OBSERVE THE MINIMUM CLEARANCES. DO NOT
STORE FIREWOOD WITHIN THIS CLEARANCE
SPACE. FAILURE TO MAINTAIN CLEARANCES TO
ALL COMBUSTIBLES MAY RESULT IN A HOUSE
FIRE.
There are listed clearances for your fireplace insert,
which were determined in a Laboratory testing and
must be maintained.
Stove top to mantel: 27" (686 mm)
Stove top to trim: 16" (406 mm)
Stove side to trim: 6" (152 mm)
Stove side to sidewall: 6" (152 mm)
For installation with a combustible mantel or top trim,
Part #16101 deflector must be installed.
DRAFT REQUIREMENTS
The appliance is merely one component of a larger sys-
tem. The other equally important component is the vent-
ing system. This is necessary for achieving the required
flow of combustion air to the fire chamber and for safely
removing unwanted combustion byproducts from the
appliance. If the venting system's design does not pro-
mote these ends, the system may not function properly.
Poorly functioning venting systems may create per-
formance problems as well as be a safety hazard (i.e.
an oversized chimney may result in less than optimum
performance. Installations into a large, masonry chim-
ney may require a liner to improve performance). A
draft test should read greater than .04' W.C. (inches
water column) and less than .08" W.C.
American National Standards Institute ANSI/NFPA 211-92,
draft 1-7: A chimney or vent shall be so designed and con-
structed 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.
PROVIDE ADEQUATE AIR FOR COMBUSTION
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.
To provide the needed air, crack a window on the wind-
ward side of the house.
VENTILATION REQUIREMENTS
THE FRESH AIR REQUIREMENTS OF THIS APPLI-
ANCE MUST BE MET WITHIN THE SPACE WHERE
IT WILL BE INSTALLED.
Ventilation is essential when using a solid fuel burning
heater. The combustion process of this heater uses
oxygen from inside the dwelling and it may be neces-
sary to open a window or install a vent to provide make-
up air into a dwelling that is well insulated (modern con-
struction standards have resulted in homes that are
highly energy-efficient and that allow little heat loss and
air transfer). Other appliances in the dwelling also con-
tribute to removing air from the dwelling (i.e. clothes
dryers, exhaust fans, fireplaces, and other fuel burning
appliances). If the available fresh air delivery in the
dwelling is insufficient to support the demands of these
appliances, problems can result (i.e. excessive negative
pressure can develop in the dwelling which will affect
the rate at which this appliance can draft. See
Draft Re-
quirements on this page).
