Opening and Removing Door
CAUTION: Do not open the glass door when the fireplace is
burning. Let the unit cool before opening the door. At the top
of the glass door are two spring-loaded latches. While holding
the door against the firebox, pull each latch forward and up -
releasing the top of the glass door. To remove the door, grasp it
firmly with both hands and lift it up so the two tabs at the bottom
of the door are lifted out of their retaining slots. The glass door
is quite heavy, so it is important
to place it in a secure spot until
reinstalled. To reinstall the door,
the tabs at the bottom of the door
must be inserted in the slots at
the bottom of the firebox. The
spring loaded latches must be
pulled forward and down to apply
pressure against the door.
Glass/Door Maintenance
Cleaning: When cool, the glass may be cleaned with a clean, soft cloth
and a household glass cleaner. For cleaning white condensation from
the interior glass use a gas fireplace glass cleaner available from your
fireplace dealer. Use of caustic or abrasive cleaners may damage glass.
Gold or nickel plated doors must be cleaned with a household glass
cleaner or denatured alcohol and a soft cloth before firing or fingerprints
and stains will remain permanently. Never use abrasive polish to clean
the gold or nickel as it will ruin the finish. DO NOT operate fireplace with
broken glass. DO NOT clean door or glass when hot. DO NOT abuse glass
door by striking or slamming shut. DO NOT use substitute materials if
replacing glass. DO NOT spray commercial glass cleaner with ammonia
on the door and glass gasket as it may dissolve the gasket glue.
WARNING: Do not operate appliance with the glass panel re-
moved, cracked, or broken. Do not remove the glass door while
the fireplace is hot. Replacement of the glass door should be
done by a qualified service technician.
Glass Replacement: The glass in the fireplace door cannot be replaced
separately. Should the glass be damaged, the entire glass, gasket and
frame assembly should be replaced as a unit. This replacement glass as-
sembly is available from your Lennox Hearth Products dealer. The glass
is neo-ceramic and alternative types must not be used.
Blower Removal
Disconnect the power supply at the household electrical panel prior to
blower removal. The blower can be accessed through the lower door on
the fireplace face.
CAUTION: Label all wires prior to disconnection when servic-
ing controls. Wiring errors can cause improper and dangerous
operation. Verify proper operation after servicing.
Door Latch
See the fan wiring diagram on Page 22 for reference. The blower is located
at the rear of the open area beneath the firebox. (During installation of
the fireplace, if the gas line was fed in from the right side it will now need
to be removed). To remove the blower, disconnect the wiring by pulling
the two spade connectors loose at the blower motor. The blower rests
on two pins - one located at each end of the blower. Grasp the blower
assembly at each end and pull the blower forward off the two pins. (If the
blower assembly is pulled from the center, it may distort the assembly).
The blower can then be carefully pulled out from under the fireplace. To
install the blower repeat the steps in the reverse order. There is a rubber
grommet at each end of the blower assembly which slides over the pins
supporting the blower. Make sure these grommets are in place when
reinstalling the blower.
Fuel Conversion
Converting the Ravelle™ 42 gas fireplace between natural gas and LP can
be accomplished by either changing the cassette (valve and pilot assembly)
or installing a conversion kit (regulator, burner orifice and changing the
orifice position on the pilot). Only a qualified service technician should
perform the conversion.
Cassette Removal:
1. Be sure the gas supply is shut off and the fireplace electrical supply
is shut off at the electrical panel before beginning the conversion.
Disconnect the gas supply from the fireplace, being careful not to
apply pressure to the valve in the process.
2. Remove the log set and brick panels (see Brick Panel and Log Set
Installation).
3. Remove the two allen head screws at the left and right rear of the
firebox securing the burner support. Lift out the burner and burner
support.
4. Remove the two allen head screws holding the burner in place.
5. Remove the labeled cover through which the valve control knobs
protrude by removing the two allen head screws securing
it and slide it off the valve knobs.
6. Mark and disconnect wires on valve terminals #1 and #3 connected
to the burner on/off switch, thermostat, or remote control.
7. Remove all the allen head screws (around the perimeter of the cassette
panel) fastening the cassette to the firebox.
8. Grasp the cassette assembly from inside the firebox and pull it into
the firebox and out of the fireplace.
9. Install new, converted, or serviced cassette in the reverse order of
removal. Replace gasket if necessary.
10. All parts and wires must be correctly reinstalled to ensure safe and
proper operation of the unit.
Conversion Kit:
Please see instructions provided with conversion kit.
