Power cable (6)
• The stove/firebox comes with a power cable which must be connected
to a 120V AC electrical outlet mains socket. Connection to the rear of
the stove/firebox is shown in fig. 42.
• The power rating is indicated in the paragraph "TECHNICAL DATA".
a
The appliance must be connected to an efficient earthing/
grounding system.
a
Any stove installed in a mobile home must be electrically
grounded to the steel chassis of the home and bolted to the
floor in Model compliance with, and according to building
code requirements.
a
Ensure that in its normal position the power cable does not
come into contact with any heated parts.
a
Ensure that the electrical plug is accessible also after
installation of the stove.
a
In Canada, the electrical installation must meet the appliance
requirements for CSA C22.2
Room sensor connection (5)
• When installing the stove/firebox, it is necessary to connect the room
sensor (provided) to the correct jack (Fig. 40). The sensor can be
positioned as shown in fig. 41, otherwise remove the band, uncoil the
lead and then place the sensor in a spot where a more accurate room
temperature reading can be obtained.
Pipe tap (3)
• The appliance has an external socket for measuring the pressure
(vacuum) of the flue gas outlet pipe. This control and verification should
be carried out by authorised personnel at the time of installation or
during maintenance.
Connection to the DB9 serial socket (7)

5.3 INSTALLING ThE ExTERNAL ThERMOSTAT

The appliance is designed for connection to an external room thermostat
(not included in the package).
To connect the thermostat use a 2x0.5 mm
cable gland to be inserted in the relative hole in the rear panel (Fig. 40).
Only authorised personnel should carry out this operation.
a
Installation can be carried out with any type of room thermostat
but requires a PG7 cable gland similar to that shown in fig. 44.
To connect the room thermostat to the electronic board, refer
to the wiring diagram.
To install, proceed as follows:
- cut off the electricity to the appliance before opening it;
- remove the electronic board protective panel (Fig. 44);
- remove the knockout to be found in the rear panel (position 4 – figure
40);
- clamp the thermostat cable with the PG7 cable gland and insert the
gland into the hole in the rear panel (Fig. 45);
- connect the thermostat terminal to the 2-pin terminal of the electronic
board (see WIRING DIAGRAM);
- replace the electronic board protective panel.
