Technical data

1. BOILER APPROPRIATION
Low temperature water boilers (up to 95ºC) are produced as 18, 25, 40, 60 and|
80 kW units. They can work on gravitation and in forced (pump) circulation. It is not
necessary to change the whole existing system especially for the boiler.
2. GENERAL REQUIREMENS REFERRED TO THE ORLAN BOILERS
Boiler start-up, programming and first setting up should be carried out by qualified
staff, being familiar with this operating manual.
Main requirements:
a) Boiler can be placed on the heating room level or at the basement
b) There should be enough space foreseen for fuel storage; fuel can be stored in
the same boiler room or in separate room but special care should be taken with
fire-fighting rules
c) Floor, ceiling and walls should be made of nonflammable materials according to
the obligatory rules. In case of flammable floor it should be covered by the metal
sheet with 0,7 mm thickness at least 0,5 m around the boiler
