Welcome among the customers of our products!
We hope that our new type, economic, reliable water heater, which requires little room will satisfy
you in all respects. To have an undisturbed operation, long durability and economical running please
study the Instructions for Use thoroughly.
The heating appliances are adjusted to the desired type of gas. The devices equipped with a
room thermostat or with another switching type controller (e. g.: with a timer) work fully automatically.
The appliances can be used either for opened or closed loop heating systems. For a closed loop
heating system the suitable fittings- a closed expansion tank, a safety valve, a pressure gauge are
needed. Although the appliance is not suitable for direct connection to floor heating systems,
appropriate auxiliary fittings allow this application.
The boilers can be deployed altogether with a water heater. If the regulations for the chimney
or for the air space make it required, a blocking system must be used.
Major particulars for the sake of your safety and peace
Boilers can only be operated by a person who has learnt their operation, knows the fire safety
regulations and is not disabled.
If the regulations laid down in the Instructions for Use are not met, the operator of the appliances is
liable for all the ensuing consequences. It is PROHIBITED to take hot water directly out of the boiler or
out of the heating system!
If the operator notices that the pilot extinguishes on its own (e.g. as a result of gas cut-off),
switch it on after about a minute, if it extinguishes again or you notice any kind of disorder (e.g. gas
leakage, excessive smoke, unpleasant smell, etc.) put the appliance out of action. Turn off the gas tap
under the appliance and cut off the current.
In case of a gas leakage turn off the gas valve under the appliance, air the room (meanwhile
do not switch on any electric appliance, do not move any electric wall plug, do not employ an open
fire). In case of further gas leakage turn off the main gas valve under the gas meter. The gas leakage
must be reported to the local gas company.
Disorders can only be fixed by a skilled serviceman. The appliance MUST NOT be used until
the disorder is fixed!
In case of failure of the appliance, skilled repairmen of gas appliance services must be
contacted (addresses of service networks is enclosed). For housekeeping purposes in the room where
the boiler is mounted, only one - in a flat maximum two-either 11,5 kg or 23 kg loading weight gas
cylinders can be stored with a total loading weight not more than 35 kg.
Flammable materials cannot be kept under and nearer than 60cm beside the appliance. The
instructions for use must be preserved and kept in a place where it is available for the operator. If it
gets lost it must be substituted.
