Page 3: Boiler Characteristics
Dear Customer, You have become an owner of a cast-iron PROTHERM KLO boiler, for natural gas or LPG. We believe it will serve you to your full satisfaction – certain minimum requirements must be fulfilled to that end. That is why we are asking you to study and follow these instructions carefully. - Page 4 It is an absolute necessity, for combined heaters (HCW+DHW), to exclude bringing "foreign" voltage to the boiler – i.e., the thermostat contacts must be separated from the heater's internal electrical components. The DHW reservoir is heated by a separate circuit, controlled by a three-way distributing (not mixing!!!) valve. The valve must be equipped with an electric switching contact (applicable only to 20, 30, 40, 50 KLO), which is connected if the valve's motor is not active (gets no voltage).

PROTHERM KLO – P types are designed for LPG; the calorific value of natural gas is about 12.8 to 13 kWh/kg. Operation using cylinders would be problematic, due to both sufficient volume and handling of the cylinders; hence a prerequisite for the operation is an installation of an LPG tank near the heated premises and filling of the tank by an organisation authorised for such activities. - Page 9 When filling the system with water, perfect purging of air in both the boiler and the heating circuit must be carried out. Depending on the water composition and the expected quantity of sludge, cleaning the boiler of sludge is recommended about a week after commencing operation.
- Page 10 Sufficient clearance space must be provided around the boiler to enable manipulation of the boiler and its accessories, both when being installed and during operation. The boiler is put on the floor (or a special base plate). The floor must have at least usual load capacity and must not be slippery. The area at the boiler must be dry-cleaned (such as vacuum cleaning).

5.3. Boiler Operation Boilers whose functionality has already been verified by the First Heating are started as follows: The power cord must be plugged into the socket. Set the heating water temperature regulator to about 2/3 of its range – the setting can later be adjusted according to the temperature of the heating water. -

If you have any doubts, feel any data to be incomplete, any advice unclear, or think that there has been an inadequate servicing of the boiler, contact one of the contractual service centres. 8. Warranty The warranty on PROTHERM KLO boilers is provided as specified in the Guarantee Certificate, Service Booklet and under conditions specified in these Instructions. 9. Complete Delivery 9.1. -
Page 15: Transportation And Storage
10. Transportation and Storage When leaving the manufacturing plant, the boiler is fixed (bolted) on a palette .Do not let any forces act on the casing when handling or when storing the boiler! For handling without a palette, the base can be used (cf. Chapter 2). For storage, normal conditions have to be provided (non aggressive environment, air humidity up to 75%, temperatures between 5°C and 55 °C, low dust nuisance, no biological factors). -
