For the UK adaptor this is a 240 volt 50 Hz. a.c. supply. For the
European adaptor this is a 220 volt 50 Hz. a.c. supply. THE MAINS
ADAPTOR MUST BE USED. DO NOT CONNECT A MAINS
SUPPLY DIRECTLY TO THE STOVE.
Plug the connector from the adaptor into the socket on the wire from
the stove. Cable clips or conduit should be used to retain the wire
where necessary. If it is necessary to extend the wire then ensure that
the correct polarity is maintained. The centre pin on the plug must be
positive. There is a thermal cut out linked into the fan control. This
means that the fans will not operate until the stove warms up.

AIR SUPPLY

The fire needs air for combustion, there are various ways of
supplying this, and they must meet the requirements of the building
regulations.
One way of meeting this requirement as outlined in Approved
Document J is to have a permanently open air vent into the room
that the stove is fitted to as per the table below:
If using this method then the air supply ducting may be terminated in
the room, or the ducting connections on the stove can be removed,

as detailed in figure 14 so that air is taken from between the fire box
and the convection casing.
Alternatively a fixed ducted air supply method can be used as shown
in fig. 13. One end of the air supply ducting is connected to the stove
and the other is terminated outside. The ducting must be 100mm dia,
non-combustible, less than 5.5m long and must not have more than
five 90° bends and two 45° elbows. It must be sleeved where it
passes through the external wall. The inlet must be permanently open
and the duct free of any constrictions. The inlet must have a suitable
grill to prevent entry by vermin, and should be positioned so that
blockage by leaves or other debris will be avoided. Ensure that rain or
flood water will not enter the duct. A spillage test must be carried out
during commissioning to verify adequate air supply for combustion -
see the section on Commisioning.
External air kits are available, please contact Charnwood for more
information (Ref TIS 120)
