A gas door glass cleaner (available from your Lennox Hearth
Products dealer) or windex should be used with a soft cloth
to clean the glass. Do not use an abrasive cleaner.

door (metal frame, gasket, and glass) should be replaced
as a unit. This replacement unit is available from your Len-
nox Hearth Products dealer. Do not use substitute parts or

Unplug the power supply cord from the electrical outlet prior
to removing the blower. The fan can be accessed through the
back wall of the firebox. Caution: Label all wires prior to
disconnection when servicing controls. Wiring errors can
cause improper and dangerous operation. Verify proper
operation after servicing. See the fan-wiring diagram below
for reference. Remove the glass door, log set, and brick pan-
els. All of these items are fragile so handle them with care.
Remove the two allen-head screws at the left and right front
of the air control panel and lift the panel out. Next, remove
the nine allen-head screws around the outside of the panel
fastened to the back wall of the firebox. Rotate the top of
this panel toward the front, remove the two wires connected
to the fan, and then lift the panel with the fan attached out
of the firebox. To reinstall the fan, repeat these steps in the
reverse order.

leCtriCal requirements
This gas insert operates without an outside power source,
however the fan/blower requires a 120 Volt electrical service
outlet. The blower must be electrically grounded in accor-
dance with local codes. In the absence of local grounding
codes, the National Electrical Code ANSI/ NFPA 70 - latest
edition. The blower is equipped with a three pronged (ground-
ing) plug for your protection against electrical shock hazard
and should only be plugged into a properly grounded three
prong receptacle. DO NOT CUT OR REMOVE THE GROUND-
ING PRONG FROM THE PLUG FOR ANY REASON!
• See Millivolt Control Schematic (Figure 19) for information
on thermostat and On/ Off switch.
• See Blower Wiring Diagram (Figure 1) for information on
the wiring and electrical requirements for the blower.
