Installation of Electrical Supply
The R720* / R820* is supplied with an external electrical control
panel pre-wired by the factory� The control box is connected to the
fireplace with a 20 foot long control cable that will communicate with
the fireplace. The control panel should be located where it can be
accessed when the fireplace has been finished in.
The power cord from the power vent module plugs into the side of
this panel� The 20 foot low voltage wire is attached and connected
to this panel as well. Connect a single pole On/Off switch (Black and
White) to these two wires at a location of your choice, (See Installing
the Remote Switch).
Montigo supplies 20' of low voltage wire to the electrical control panel.
Connect the two wire harnesses to a standard single pole ON/OFF
switch to the location of your choice� You may extend these wires
up to 100' in length with a wire of equal quality.
