TANK LOCATION
1.The fuel tank is good to be placed beneath
the heater foot. Fig. 4. (The surface of the
liquid fuel must be beneath the foot). When
the liquid surface is above the heater foot, a
magnetic valve is recommended to install
near the tank end.
2.The fuel tank may be installed into its foun-
dation casing or outside, for example, into
the basement of the house or inside a sui-
table, protective casing. The fuel tank and
hose must be protected from direct sunlight.
3.The fuel hose inlet through the constructions
must be protected by a metal pipe.
4.The basic length of the fuel hose is 3 met-
res. It may be extended by using a 2-metre
extension hose which makes the total hose
length 5 metres. The hoses are linked by
using threaded quick connectors. Fig. 4
shows the maximum limits of the installation.
BATTERY LOCATION
1.The equipment contains 4 metres of electri-
cal wire with a thickness of 4 mm
2
. In case
the distance between the battery and equip-
ment is 6 metres, the cabel thickness must
be 6 mm
2
and so on.
2.The electrical wires must be protected by pla-
cing a 15 A fuse at the battery end of the po-
sitive cable of the electrical wire.
3.The battery should be located so that there
will not be any danger when the battery is
charged or used.
N.B. The voltage must be primarily taken di-
rectly from the battery, not from the control unit
of the solar battery. This will ensure that the
system bears the ignition current and does not
receive excess voltage. Contact your system
supplier for further details.
INSTALLATION HOLES
1.Choose the place for the heater. See instruc-
tions above.
2.Exhaust gases shall always be led out. If de-
sired, they can be led out directly through the
wall. In this case, the combustion air is also
taken from outside, which contributes to ba-
lancing the pressure fluctuations caused by
the wind. See the separate leaflet describing
installation alternatives.
3.Make holes through the wall according to the
dimensions given in fig. 5. In the case of duct
installation, the hole for exhaust gas (diame-
ter 120 mm) shall be dimensioned in its cor-
rect location. Make a separate hole for fresh
air (diameter 50 mm) in the fresh air duct or
through the floor. (For sizes of the holes, see
fig. 5). As far as a duct installation is con-
cerned, the fire ventilation air may also be
taken from indoors.
