PLANNING YOUR INSTALLATION
PAGE 7
FACTORY BUILT FIREPLACES
This appliance is approved for installation into a listed factory
built solid fuel burning fireplace. The fireplace firebox must
accept the insert without modification other than re-
moving bolted or screwed together pieces such as
smoke shelf/deflectors, ash lips, screen or door tracks
and damper assemblies, that must be reinstalled to re-
store the fireplace to its original operating condition if
the insert is removed and not replaced. The removal of
any part must not alter the integrity or outer shell of the
pre-engineered fireplace cabinet in any way.
Venting Requirements for factory built fireplace:
The fireplace damper must be secured in the open position.
This appliance requires the use of a 6” diameter flex or
rigid, UL1777 listed 2100
°
HT liner or equivalent. The
liner must extend from the flue outlet of the appliance to
termination. Do not face seal over fireplace chimney
cooling air systems. Offsets can be handled with an offset
adapter (it aligns starter pipe with fireplace flue). For more
information on the offset adapter, see pages 9 and 25.
WARNING: Do not substitute the heat rated
2100
°°°°
HT liner with any other type line or a fire
may result causing property damage, personal
injury or loss of life.
MASONRY FIREPLACES
This appliance is approved for installation into a masonry
fireplace built to UBC Chapter 37 standards. Do not remove
brick or mortar form the masonry fireplace to accommodate
this appliance.
Venting Requirements for masonry fireplace:
The fireplace damper must be secured in the open position.
As a minimum, a flue extension past the fireplace header is
required. A preferred installation is a positive flue connection
(sealing the throat of the chimney). This appliance requires
the use of a 6” diameter flex or rigid single wall pipe,
minimum 24/25 MSG black or blued steel connector
pipe (stainless steel recommended). Offsets can be han-
dled with an offset adapter (it aligns starter pipe with fireplace
flue). For more information on the offset adapter, see pages
9 and 25.
FIREPLACE CHIMNEY MAXIMUM SIZE TO ENSURE
PROPER DRAFT
The fireplace insert flue size is 6 inches diameter, which
is approximately 28 square inches, the minimum. The
maximum flue size should be no more than (3) three
times the cross sectional area of the size of the fireplace
insert flue collar. In this case, that would be no larger
than a 10 inch diameter stack (area = approx. 85 sq.
inches).
Note: Formulas for calculating area:
Calculating area of a circle:
π
x r
2
= Area (
π
= 3.1416, r = 1/2 diameter)
To calculate area of square or rectangle:
Width x Depth = Area
Notes:
!
It may be necessary to use a full-length liner to
achieve adequate draft for the appliance. A draft
gauge should read more than .04 W.C.I, but less
than .08 W.C.I. for optimum performance
.
!
This appliance is approved for all heatform style
fireplaces (masonry fireplace with a metal fire-
box liner).
!
Measure fireplace size to make certain the insert will
fit before considering the installation.
