spillage, and to maximize performance. Gauges to
measure draft are readily available at stove stores
and are economical to rent or purchase. Factors
such as wind, barometric pressure, trees, terrain and
chimney temperature can have an adverse effect
on the draft. The manufacturer cannot be held
responsible for external factors leading to less than
optimal drafting. Should you have a problem with
inadequate draft, you should contact a licensed
heating and cooling contractor for assistance in
solving the problem.
FIREPLACE CONDITION AND ZERO
CLEARANCE REQUIREMENTS
A masonry replace must meet minimum code
requirements, National Fire Protection Association,
(NFPA) 211, or the equivalent for a safe installation.
Contact a professional, licensed installer, your local
building inspector or the local re authority for the
requirements in your area. Your insurance company
should be able to recommend a qualied inspector.
Inspections should include the following:
1. Condition of the replace and chimney. A
masonry replace and chimney MUST be
inspected prior to installation of this appliance.
They must be free from cracks, loose mortar,
creosote deposits, blockage or other evidence
of deterioration. If found, these items MUST be
repaired prior to installation. DO NOT REMOVE
BRICKS or MORTAR from existing replace
when installing this unit.
2. Chimney Size. Minimum chimney size is 6” (153
mm) diameter. Maintain a 15 ft. minimum overall
chimney height measured from the top of
appliance to the top of the chimney. Chimneys
must extend at least 3 ft. above the roof and at
least 2 ft. above the highest point within 10 ft. of
the chimney top. See the Chimney Connections
section of this manual.
3. Zero Clearance or Metal Heatform Fireplaces.
These replaces and chimneys must meet
the minimum code specications as noted
above. Factory built zero clearance replaces
must be listed and suitable for solid fuel use.
Chimneys must be at least 7 inch diameter to
accommodate a required, continuous, stainless
steel liner from the appliance’s ue collar
to the top termination of the chimney. Only
detachable parts that can be easily replaced (i.e.
damper parts, screens, doors and side, and back
refractory panels) are to be removed. These
parts must be stored and readily available for
replacement if the appliance is ever removed.
The removal of any parts that render the
replace unusable for burning solid fuel
requires a permanent label to be afxed by the
installer that states the replace is unsuitable
for burning solid fuel unless the missing parts
are replaced and the replace is restored to its
original, certied condition.
4. Chimney Caps. Mesh type chimney caps and
spark arrestors must be able to be removed for
regular inspection and cleaning. Otherwise the
mesh should be removed to prevent possible
plugging. Check your local re and building
codes.
5. Chimney Liner. The chimney must be suitable
for burning solid fuel. Install a continuous
stainless steel liner from the ue collar of the
appliance to the top of the chimney. Liner must
be UL Listed to UL1777.
6. Combustible Material Clearances. The replace
and chimney must be inspected to make sure
there is adequate clearance to combustible
materials. This includes the top, side, front,
and back as well as concealed combustibles
in the chimney and mantle areas. Your local
building inspector or re authority should have
information on whether older replace meet
current codes and are suitable for use.
7. Makeup Air Requirements. This appliance
requires an adequate supply of makeup air to
operate safely and efciently. In some areas, this
is a building code requirement. Inadequate air
supply will cause poor combustion, inefcient
operation, creosote buildup, back drafting and
smoke pufng into the living areas. If any of the
following conditions are evident, a makeup air
supply MUST be installed.
a. Existing fuel-red equipment shows evidence
of back pufng, smoke roll-out, inefcient
operation, or excessive smell in the living area.
b. Opening a window or door alleviates any of the
above problems or symptoms.
c. The building is constructed with a well-sealed
vapor barrier, tight tting windows, or has
powered exhaust fans.
d. Excessive condensation on windows in the
winter.
e. The building has a ventilation system installed.
