Fuel Conversion
Converting your Medina™ gas insert between natural gas and LP can
be accomplished by installing a conversion kit (valve regulator and
burner orifice). Only a qualified service technician should perform the
conversion.
Conversion Kit: Please see instructions provided with conver-
sion kit.
Blower Removal
Unplug the power supply cord from the electrical outlet prior to remov-
ing the blower. The blower can be accessed through the back wall of
the firebox.
CAUTION: Label all wires prior to disconnection when servic-
ing controls. Wiring errors can cause improper and dangerous
operation. Verify proper operation after servicing (see the blower
wiring diagram below for reference).
Remove the insert face, glass door and log set. All of these items are fragile
so handle them with care. 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
blower and then lift the panel with the blower attached out of the firebox.
To reinstall the blower, repeat these steps in the reverse order.
Electrical Requirements:
This gas insert operates without an outside power source, however the
blower requires a 120 Volt electrical service outlet. This appliance, when
installed, must be electrically grounded in accordance with local codes,
or in the absence of local codes, the National Electrical Code ANSI/NFPA
70 - latest edition. (See Operating Options for thermostat and ON/OFF
