For altitudes above 2,000 feet (In Canada 4,500 FT/1370 M), the orifice
should be de-rated by 4% for every 1,000 feet to maintain the proper
ratio of gas to air. Improper orifice sizing may result in damage and
unsafe conditions. Changing the orifice should only be done by a quali-
fied service technician. Contact your Lennox Hearth Products dealer for
proper orifice sizes.
ORIFICE SIZE/ALTITUDE ADJUSTMENT Fireplace Requirements
These heaters are designed to be installed into an existing masonry
fireplace (built to UBC 37 or ULC S628 standards) or factory built solid
fuel, wood burning fireplace (listed to UL 127 or ULC S610) only. All
exhaust gases must be vented outside the structure. Combustion air
is drawn from outside the structure. When installing in a factory built
fireplace, the fireplace grate must be removed and the damper must be
removed or secured open.
If the factory-built fireplace has no gas access hole(s) provided, an access
hole of 1-1/2 inches (38 mm) or less may be drilled through the lower
sides or bottom of the firebox in a proper workmanship like manner. This
access hole must be plugged with a non-combustible insulation after the
gas supply line has been installed. The installer must mechanically attach
themarkingsuppliedwiththegasfireplaceinsert to the insideof the firebox
of the fireplace into which the gas fireplace insert is installed.
IMPORTANT: When installing these appliances into a factory
built fireplace or heat-form, the air flow within and around the
fireplace shall not be altered by the installation of the insert
(i.e. DO NOT BLOCK louvers or cooling air inlet or outlet ports,
circulating air chambers in a steel fireplace liner or metal heat
circulator).
THE RAVENNA™ FIREPLACE
Since there are always several potential sources of fire in any home, we
recommend installing smoke detectors. If possible, install the smoke
detector in a hallway adjacent to the room (to reduce the possibility of
occasional false activation from the heat produced by the appliance). If
your local code requires a smoke detector be installed within the same
room, you must follow the requirements of your local code. Check with
your local building department for requirements in your area.

CAUTIONS
•Trim panels or surrounds must not seal ventila-
tion openings in the existing fireplace that the
appliance is installed in.
•The fireplace in which this gas insert is to be
installed must be thoroughly cleaned if it has
been used to burn wood or synthetic logs. Have
the chimney and all inside surfaces of the fire-
place brushed and vacuumed so that no soot,
embers, or loose combustion deposits can be
drawn into the heat circulation blower and blown
into the living area.
•If any portion of the chimney system shows signs
of structural or mechanical weaknesses, such
as: cracks, leaky joints, corroded or warped
surfaces, the faulty portion must be repaired
or replaced prior to installing this appliance.
•The factory built firebox must accept the insert
without modification other than removing bolted
or screwed together pieces such as baffles /
smoke shelf / deflectors, ash lips, glass door,
screen or door tracks, log grates, refractory or
masonry lining and damper assemblies. Any
fireplace component, which is removed, must be
retained so they can be reinstalled to restore the
fireplace to its original operating condition. The
removal of any part must not alter the integrity
of the outer shell of the pre-engineered fireplace
cabinet in any way. Any parts removed must be
replaceable. If any components are removed
from (or altered) from the existing fireplace,
a Warning Label (see Page 4) must be affixed

(ZC) fireplace. When installing in a ZC fireplace, the ZC grate must be
removed and the ZC damper must be removed or secured open. The ZC
doors, screen, refractory or masonry lining, baffles and smoke shelf may
be removed if necessary to install the gas insert. However, do not cut
or alter the fireplace components. The removal of any parts to facilitate
installation must not alter the integrity of the inner or outer shells of the
fireplace cabinet. Any parts removed must be replaceable if the insert is
taken out of the fireplace or the fireplace clearly marked with a paint stick
that "This fireplace has been altered and is no longer safe to operate."
The insert is designed to fit into a ZC fireplace with a minimum firebox
height of 19-1/2" (495mm). To facilitate this the hood will need to be
removed and discarded (Note: The screws should be replaced in the
insert body).
If the factory-built fireplace has no gas access hole(s) provided, an ac-
cess hole of 1-1/2" (37.5 mm) or less may be drilled through the lower
sides or bottom of the firebox in a proper workmanship like manner. This
access hole must be plugged with a non-combustible insulation after the
gas supply line has been installed.
The installer must mechanically attach the marking supplied with the gas
fireplace insert to the inside of the firebox of the fireplace into which the
gas fireplace insert is installed.
Ravenna™ 40 Conversion To Ravenna 33
To convert to a Ravenna 33 gas insert, after step 1 remove and replace
the stock burner orifice with the #36 NG orifice supplied in the installation
manual bag. Pipe dope or other approved gas line sealant will need to be
applied before inserting into bulkhead. The foil sticker supplied, stating
RDV33, will need to be affixed over the model name RDV40 on the serial
number label (located in the control compartment).
Brick Panel and Log Set Installation
If logs are not installed according to the log installation instructions,
flame impingement and improper combustion could occur and result in
soot and/or excessive production of carbon monoxide (CO), a colorless,
odorless, toxic gas.
The size and position of the log set is critical to achieve a safe, reliable
and attractive flame pattern. Any attempt to use a different log set in the
fireplace will void the warranty and will result in incomplete combustion,
sooting and poor flame quality.
1. Remove the log rack (2 screws) and install the rear log on the re-
tainer.
