Ovalizing Round Stainless Steel Liners; Chimney Height / Rise And Run - Quadra-Fire 41I-ACC Owner's Manual

41I ACC Wood Insert
I. Zero-Clearance Fireplace
A permit may be required for installations, final approval is
contingent of the authority having local jurisdiction. Consult
insurance carrier, local building, fire officials or authorities
having jurisdiction about restrictions, installation inspection,
and permits
.
Inspect the existing fireplace and chimney for any damage
or flaws such as burnouts, metal or refectory warping.
Inspection to a minimum of NFPA 211 Level II is recom-
mended. All repairs must be made prior to installing an
insert. The fireplace must be structurally sound and be able
to support the weight of the solid-fuel insert
The factory-built chimney must be listed per UL 127 or ULC
610-M87 for all installations. Install thermal protection per
this appliance listing requirements.
A full height 6 inch diameter stainless steel full height
listed chimney liner must be installed meeting type HT
(2100°F) requirements per UL 1777 (USA) or ULC S635
with "0" clearance to masonry (Canada). The full liner
must be attached to the insert flue collar and to the top
of the existing chimney.
The flue liner top support attachment must not reduce the air
flow for the existing air-cooled chimney system. Re-install
original factory-built chimney cap only. (See Section F.,
Prefabricated Metal Chimney)
To prevent room air passage to the chimney cavity of the
fireplace, seal either the damper area around the chimney
liner or the insert surround. Circulating air chamber (i.e. in
a steel fireplace liner or metal hearth circulator) may not be
blocked. The air flow within and around the fireplace shall
not be altered, blocked by the installation of the insert. (i.e.
no louvers or cooling air inlet or outlet ports may be blocked
by the insert or the insert surround.
See "H. Altering the Fireplace" for modifications allowed for
factory-built fireplaces.
WARNING! Risk of Asphyxiation!
• DO NOT CONNECT THIS APPLIANCE TO
A CHIMNEY FLUE SERVICING ANOTHER
APPLIANCE OR TO ANY AIR DISTRIBUTION
DUCT OR SYSTEM.
This may allow flue gases to enter the house.

J. Ovalizing Round Stainless Steel Liners
Ovalizing round stainless steel liners to accommodate the
liner passing through the damper region of a fireplace is an
allowable and acceptable practice.
Ensure that the ovalization is minimized to the extent
required to fit through the damper.
K. Chimney Height / Rise and Run
To be sure that your Quadra-Fire insert burns properly, the
chimney draft (static pressure) should be approximately -0.07
inches water column (W.C.) during a high burn and -0.04
inches W.C. during a low burn, measured 6 inches (152mm)
above the top of the insert after one hour of operation at each
burn setting.
NOTE: These are guidelines only, and may vary somewhat
for individual installations.
• This product was designed for and tested on a 6 inch
(152mm) chimney, 14 to 16 feet (4.27-4.87m) high, (in-
cludes appliance height) measured from the base of the
appliance.
• The further your stack height or diameter varies from this
configuration, the possibility of performance problems ex-
ists.
• Chimney height may need to be increased by 2 - 3% per
each 1000 feet (304.8m) above sea level.
• It is not recommended to use offsets or elbows at altitudes
above 4000 feet (1219.2m) above sea level or when there
are other factors that affect flue draft.
Fire Risk.
Do NOT pack insulation or other combustibles
between spacers.
• ALWAYS maintain specified clearances around
venting and spacers.
• Install spacers as specified.
Failure to keep insulation or other material away
from vent pipe may cause fire.
Fire Risk.
This appliance relies upon natural draft to operate
properly.
• Chimney heights exceeding 25 feet (7.62m) from
base of appliance may create an over-draft
situation.
• Overdraft condition may create over-firing.
Over-firing may ignite creosote and/or damage
appliance and chimney
