A properly installed Bellfires®BSV fireplace and its associated components form a
safety tested system. This manual serves as a guide for the proper and safe installation
of a Bellfires®fireplace. It does not serve as a substitute for the necessary professional
judgment and skills of a trained installer. Instead, it should be used in conjunction with
standard safety considerations including, but not limited to, applicable state or provin-
cial and local fire codes, the National Fire Protection Association Standard NFPA 211 or
Canadian Standard B365, building and inspection codes, and the trained installer’s pro-
fessional judgment and skills to provide the owner with a safe installation. Please save
these instructions for any future repairs or use.
Consult the local and state or provincial building and fire safety code officials and
investigate the requirements for installing a factory-built fireplace in the homeowner’s
community. It is the responsibility of the installer to (1) obtain a building permit for
installation of a Bellfires®BSV fireplace before construction begins and, (2) assure the
installation meets or surpasses all minimum requirements of the homeowner’s
jurisdiction.
It is highly recommended the homeowner install a smoke detector.

Early fireplaces were very inefficient, drawing a good deal of
the heat up the chimney while admitting an unbearable amount
of smoke into the room. In the late 1700’s, Benjamin
Thompson, Count of Rumford, recognizing that a fireplace
heats an area by radiation, began a series of experiments
aimed at improving its performance.
He discovered through observations and various constructions
that the exaggerated width of the chimney of his time, necessi-
tated by the need for room for a chimney sweep to climb
through the throat area into the flue, was a primary cause of
inefficiency and smokiness. He attributed the problem not only
to the chimney, but the width of the throat and also specific
fireplace dimensions and configurations. Using the knowledge
gained from his studies, Rumford modified the traditional fire-
place design into one that burned cleaner and hotter and,
most importantly, did not smoke. His efforts greatly improved
the performance of the fireplace.
Later, in the 1900’s, a series of scientific experiments were
conducted by Professor Peter O. Rosin, Dr. Ing., under the
auspices of the British Coal Utilisation Research Association.
The results are documented in his report, “The Aerodynamics
of Domestic Open Fires”. Through the use of laboratory equip-
ment, Dr. Rosin was able to observe air and smoke flow pat-
terns and thus developed the ideal firebox and chimney shape
for maximum efficiency. While expanding on Rumford’s work,
some of Dr. Rosin’s findings varied dramatically from
Rumford’s earlier theories; perhaps the most notable being the
smoke shelf theory, shown diagrammatically at the left.
The important point of Dr. Rosin’s work is that it was per-
formed in a scientific manner and pointed the way to a much
more efficient and functional fireplace. Bell of England took
this information and applied it to develop the Bellfire
Fireplace, providing the ideal firebox and throat shape to guar-
antee a smoke-free efficient fireplace capable of producing
maximum radiant heat with minimum fuel. It was commonly
used to heat the complete home until the second World War.
Since then it has been further developed by using more mod-
ern aerodynamic concepts and thermal insulation techniques
to improve the design.
Sleepy Hollow Chimney Supply has optimized the Bellfires®
designs, and produced a superior radiant firebox combining
advanced casting techniques and high temperature, high alu-
mina ladle cast refractory. We feel confident that our
Bellfires® units are the finest heat- producing open fireplaces
to be found, whether used to upgrade old metal or masonry
fireboxes or in new construction.
The Super Vent is the Repair Unit with the addition of a cor-
rectly proportioned Smoke Chamber design, constructed of
type 316 stainless steel for lifetime durability.
The Smoke Chamber is connected to a properly sized round or
oval Super Flex® flexible flue liner. Cera-Foil® space age
insulating blanket insulates the entire Super Vent™ system,
stopping heat transfer to combustibles–the cause of home
fires. In homes where the fireplace is in question for whatever
reason, the Bellfire Super Vent has established itself as a safe,
state-of-the-art, non smoking super radiant fireplace retrofit
system.
A top mounted round damper with a control key at the firebox
level helps to prevent cold air from draining into an unused
fireplace and help ensure a warm flue for instant draft. Super
radiant heat output and thorough combustion provide ample
warmth and fuel efficiency that sets new standards for the open
hearth. The refractory firebox stores heat and warms the house
long after the flames have died out.

A. Bellfires® fireplaces are not approved for use in mobile homes.
B. There must be an air space clearance between the outermost portion of any section of the chimney system and
any combustible surface. Although two inches is a typical clearance, adhere to the requirements set forth by the chim-
ney manufacturer. Combustible surfaces include: ceilings, joists, flooring, walls, electrical wiring, insulation and roof
structures.
C. Never fill any required air space with insulation or other material.
D. The chimney system must be vented to the outside.
E. The chimney must extend at least three feet (900mm) above the roof and at least two feet (600mm) above any
portion of the roof within 10 feet (3m).
F. Maximum chimney height from the top of the firebox to the top of the chimney should not exceed 40 feet when
supported solely by the fireplace, or 90 feet when resupported at or above 40 feet according to the chimney manufac-
turer's resupport specifications.
G. Minimum chimney height from the top of the firebox to the top of the chimney must be 10 feet.
H. The chimney must not be inclined more than 30 degrees from vertical. Greater angles result in hazardous
deposits of soot and ash in flue.
I. A maximum of two offsets (4 elbows total) is allowed in a chimney.
J. Firestops and joist shields must be used at each floor level through which the chimney rises.
K. There should not be any forced air furnace registers in the room within ten feet of the fireplace. They can cause
negative pressure and create chimney down-drafts.
L. Never mix parts of one chimney system with those of a different manufacturer. Do not install damaged chimney
parts. Remember, more fires are caused by chimneys than by solid-fuel appliances.
M. Practice good workmanship. Sloppy work could jeopardize the safety of the installation.

There are 6 Steps to a SuperVent
installation.
1. Measure old fireplace to determine what
size BSV unit to use, and the appropriate
liner size.
2. Demolition of firebox and smoke chamber
and preparation for the new BSV.
3. Layout for the new BSV.
4. Installation of the Super Flex® , (or Super
Rigid) liner system.
5. Installation of the BSV.
6. Finish and trim facade.
There are as many different size and
shape fireplaces as there are masons who build
them. Some are large and cavernous and some
are small and tight. It is much easier to install the
Super Vent® in a fireplace with a deep firebox
and tall, wide smoke chamber, and large flue
diameter, than an installation with a shallow fire-
box, short, tight chamber, and an undersized or
offset flue. Careful measurements should be
taken when inspecting and estimating the job.
Measurements to take during inspection/esti-
mate: A. Width of opening
B. Height of opening
C. Thickness of opening (lintel size or
arch thickness)
D. Depth of firebox behind face
E. Width of firebox rear
F. Depth of smoke shelf to rear smoke
chamber wall
G. Distance from firebox floor to base of
flue
H. Flue size
I. Total Height
Measuring fireplace (depth
of fireplace cavity)
Plumb down to floor from front edge of smoke
shelf or damper frame with level or plumb bob
and string. Measure from this point on floor to
rear of firebox. Subtract this measurement from
the depth of smoke shelf measurement. This
amount less the thickness of the firebox brick will
represent the total depth available with rear fire-
box removed.
Measure from firebox floor to base of flue tile. If
measurement from floor to flue is greater than
height of Bellfires firebox and smoke chamber,
and flue size is greater than liner size, installa-
tion will be simple and little smoke chamber
demolition will be necessary. If measurement
from floor to flue is less than height of Bellfires
firebox and smoke chamber, and/or flue size is
smaller than liner size, demolition of smoke
chamber and base of flue will be necessary.

Notes on the Bellfires®
Rumford Smoke Dome
In other installation information that has circu-
lated on BSV installations references were made
to using stainless steel elbows off of the Smoke
Dome for chimneys with offsets.
Sleepy Hollow’s custom fabrication shop makes
any dome to the exact dimensions required for
your installation. DO NOT USE elbows off of the
Smoke Dome.

(2) Demolition and Preparation for BSV
Possibilities for installations
are practically endless. Once
you have prepared the firebox
and chase for placement of
the Bellfires® BSV firebox you
are ready to trace the dimen-
sions of the box and flares on
the hearth floor. Some
installers wrestle the firebox
and flares into place and trace
the outlines from the outline
of the Bellfires®, and others
have found it easier to make a
cardboard template and use
that to find the exact place-
ment of the finished Bellfires®
in the existing fireplace.
Experience (and your back)
will lead you to a preferred
method, but both can be used.
Some installations can be
done with only minor modifi-
cations to the fireplace; others
will require more serious
demolition. This can include
removal of the existing fire-
brick (or common red brick if
a very old fireplace) firebox,
and damper throat, damper,
and smoke chamber. Only
onsite measurement will tell
you how far you will have to
go to prepare for a smooth
Bellfires® installation.
This fireplace will require
major demolition to allow for
the Bellfires® Super Vent
firebox and Super Flex®
It never hurts to lay out a job dry before doing any
demolition, and sketching out the exact outlines of the
components can save a lot of labor.
Amore common
job will require
only the removal
of the existing
firebox and clay
liners.

Preparing the customer’s
home for installation of
Bellfires® BSV fireplaces is
very important. Care should
be taken to ensure that your
customer’s home is protected
from the process the installa-
tion requires. Cover interior
walkways with weather
appropriate materials–snow
and rain create problems that
never come up when working
in dry weather . Use vaccuum
heads or exhaust fans on the
chimney top to help remove
dust and soot. Powerful vac-
cuums should be used
indoors at the points of demo-
lition to further control dust.
