PELLET BOILER KEPO MC 20 KW

The boiler contains all the elements necessary for installation in the central heating system: drain valve, safety valve (3 bar), expansion vessel, circulation pump. * In order to extend the two-year warranty for a period of 5 years (for tightness of the exchanger), it is necessary to install a thermostatic valve to prevent cold return from the installation (calibrated at 55 ° C), which will ensure a much longer life of the boiler.

The boiler has many overheating protections. The first level of protection is provided by electronics that will not allow the water temperature to rise above 85 ° C, and the second level of protection is a safety thermostat (power free - STB), which interrupts pellet dosing when the boiler reaches a critical temperature. The thermostat does not allow the boiler to overheat, reports a fault and extinguishes the boiler. The electronics do not allow the system pressure to be higher than 2.5 bar or lower than 0.6 bar. In both cases, it reports a fault and extinguishes the boiler. Should the electronics fail for any reason, the boiler is equipped with a safety valve which, at a pressure of more than 3 bar, will release the water from the boiler in order to reduce the excess pressure.

Boilers Kepo are also equipped with a pressure switch, whose task is to interrupt pellet dosing and prevent any possibility of smoke escaping into the room, it reports a fault and turns off the boiler in the event of clogging of the exhaust pipes and poor flow of exhaust gases through the chimney. The device is equipped with a mechanical flap, whose task is to reduce the pressure in the combustion chamber in the event of too dynamic ignition, and thus prevents problems in the further operation of the boiler.

Kepo offers two series of boilers, AC (with automatic burner cleaning) and MC (with manual burner cleaning) with maximum powers: 15, 20, 25 and 35 kW.

Kepo boilers are solid fuel devices, also during the combustion process they consume a lot of oxygen, so it is necessary to install a supply-exhaust (not mechanical) ventilation system in the room in which it is located. An opening of at least 100 cm² should be made in the lower part of the room in the boiler room. A vent in the upper zone of the room is required.

It is necessary to connect the boiler to an insulated chimney with a minimum height of 3 m and a minimum diameter of 130 mm.

Yes, the boiler can work automatically, which can be regulated in two ways, either by the boiler itself or by an external room thermostat.

• AC / MC 15 - 40kg
• AC / MC 20 - 62kg
• AC / MC 25 - 75kg
• AC / MC 35 - 120kg

Boiler cleaning must be regular and its frequency depends on the quantity and quality of the burnt pellets. Cleaning with turbulators is performed regularly at intervals of 3 to 7 days, and a general inspection and cleaning of the entire boiler is carried out once a year. Boiler maintenance influences the consumption of pellets and the reliable operation of the boiler.

This is one of the most important factors in the correct operation of the boiler. Depending on the conditions, the parameters are regulated and the boiler is started. After adjusting the boiler operation parameters with the chimney and air supply, the next thing that determines the correct operation of the stove is pellets. High-quality pellets are the cheapest pellets! By using high-quality pellets, you avoid:

• expenses for numerous visits of service personnel
• emergency shutdown of the boiler due to bad burning in the burner
• large amounts of sediment and ashes in the chimney flues and much more frequent cleaning of the boiler than intended
• increased (up to three times) pellet consumption

The pellet boiler works on the principle of controlled combustion, therefore the pellets must be of good quality for the boiler to run smoothly and economically.
