This appliance must be installed externally in open air
(without a flue) or indoors (with a suitable flue system)
in a room separated from living rooms and provided
with appropriate ventilation direct to the outside.
The appliance must be used only in accordance with
these instructions. Incorrect use is dangerous and
invalidates all warranties and Certification.
Conversion Instructions.
The heater is supplied in two versions,one for use
with Natural Gas, G20 at 20 mbar inlet pressure, the
other for Propane, G31 at 37 mbar. If it is necessary
to convert the heater for use on the other gas the
appropriate conversion kit must be purchased and
fitted using the instructions provided.
NOTE:
The heater should not be located in an area
where possible water leakage will result in damage
to
the area adjacent to the appliance or to the
structure. When such locations cannot be
avoided, it is recommended that a suitable drain pan,
adequately drained, be installed under the appliance.
The pan must not restrict combustion air flow.
BASE INSTALLATION
Heater must be mounted on a level base, such as
cement slab, cement blocks or other non-combus-
tible surface. An alternative method for providing a
base for combustible floors is illustrated below.
Heaters must
not
be installed on carpeting.
