frost. In rooms with aggressive steam or dust,
the appliance must be operated independent of

When choosing the place of installation and while operating the
appliance, make sure that the air supply is free of chemical
substances containing fluorine, chlorine, sulphur etc. Sprays,
solvents and cleaning agents, paints, adhesives etc. contain the
kind of substances that can lead to corrosion even in the ex-
haust system when the appliance is operated depending on the
ambient air in the worst case scenario. Particularly in hair-cut-
ting salons, lacquering and finishing, cleaning facilities, the ap-

Gas supply

The gas supplier should ensure the availability of an ade-
quate supply of gas. A gas meter may only be connected
to the service pipe by the supplier of gas or their contrac-
tor. An existing meter should be checked to ensure that it
is capable of passing the rate of gas supply required. In-
stallation pipes should be fitted in accordance with BS
6891. In IE the current edition of IS 813. Pipe work from
the meter to the boiler must be of an adequate size. Do
not use pipes of a smaller size than the boiler gas con-
nection (15 mm). The complete installation must be
checked for leaks and purged as described in BS 6891.
d Danger!
