Ultima is floor standing  one function solid fuel boiler for combustion of wood and coal. Capacity range from 15 to 40 kW helps to install boiler in almost every one/two family house and in garages, small shops as well.

Special system of multi injection of air flow to the combustion chamber makes Ultima Plus with fan semi woodgas boiler in very attractive price.

For customers looking for not digital control panel and fan, we have standard version of Ulitma boiler with manual regulation of flame and fuel combustion

Boiler is produce in 2 versions: with fan and natural draught.

1) Multi injection air flow system

Unique structure of combustion chamber with special nozzles for air stream are located in everyside of the chamber. Thanks this system ignition, combustion process are coming very calm and precise, efficiency of the boiler comes up to 84 % and we are avoiding smoke by start of the boiler.

2) Very easy installation

Water oultlets, chimney connection, compact dimensions and weight make ,that Ultima boiler is favorite product of every installer.

Boiler is very easy to transport, arrange in boiler room and easy to clean

3)   Easy and effective operation 

Digital control panel integrated with fan and processor is very easy to use. We are operating just three buttons + - and F.

Very easy cleaning through mechanical grill and ash box, revision doors in every side of the boiler, wide loading doors help to avoid every day problems with the unit.

Thanks 2 pass and air system, we have to refuel boiler with wood every 5-8 hours (depend on wood quality and house insulation )

1. REGULATOR CHAR922724867.phpERISTIC

   The regulator  is to destined for boiler temperature setting-up. The regulator continues water temperature measurement then shows it on small screen and operates the circulating pump as well.

   The regulator is also equipped with room thermostat to assure the precise teperature regulation in the heated room space.

2. REGULATOR SET-UP

   Before feeding plug connection into the socket (230V/50Hz) it should be decided if regulator works with circulating pump or not. If first option is chosen the regulator should be taken of the boiler frame and after opening, properly connect the pump power lead to the place named “CENTRAL HEATING PUMP” .

Before regulator insertion into the casing it should be assured that the temperature sensor has not came out of the measurement casing.

Warning! Before regulator setting up it should be checked out if the wiring system is correctly connected to the ground.

Warning! A fan and pump of max. 250W can be connected to one regulator.

3. REGULATOR SERVICE

Connecting strip as well as the safety device socked is placed on the regulator back wall. On the same wall there is also placed room thermostat socked and time regulation handwheels.

4.REGULATOR WORKING Ultima boiler Ultima is floor standing  one function solid fuel boiler for combustion of wood and coal. Capacity range from 15 to 40 kW helps to install boiler in

Regulator's work is based on suitable controlling of lhe fan and heating system circulating pump to achieve assigned boiler and room temperature. After regulator switching on or after switching off the boiler overheating indicator, the regulator begins boiler buring; it is shown by green indicator.

The burning process is finished if  boiler temperature achieves assigned value and green indicator will switch off.

If  boiler temperature does not achieve 65°C during 2 hours of  boiler working, the regulator will switch on the fan and shows fuel shortage indicator.

  During its work regulator shows an actual boiler temperature and controls fan

speed as below:

          > If during ot the burning process boiler temperature is lower than 60°C

     the fan works in 40 – 100% ; if temperature is higher than 6O°C the fan

     works in 100% of its power

  > If boiler temperature during its normal work is lower than assigned value more

     than 10°C then fan works in 100% of its power

  >If  boiler temperature during its normal work is lower than assigned value less

     than 10°C then regulator reduce the fan speed but not 1ess than 40% of its

     power

  >If boiler temperature is higher or equal of assigned thermostat temperature the

     fart switches off

  > The tan will switch on again when boiler temperature gets down about 5°C of

     assigned value

  >To avoid gasses accumulation during boiler outage, the regulator makes 5­secunds blows through tne boiler every 1÷9 minute. The blows can be set-up after regulator switching on when you can see (P1... .P9, P-) on the regulator sereen; pressing (P-) you will switch off the blows.

It circulating pump works:

 >during biler burning , until boiler achieves 65°C, pump is switched oft

 > if, boiler temperature is higher tnan 65°C pump starts to work and works until

      boiler temperature gets down to 60°C to avoid excessive boiler pre-coollng

 > if, during boiler operation the temperature temporarily gets down to 60°C the

      pumpstarts to work again after temperature achieves 65°C

FUEL SHORTAGE

If boiler temperature gets down under 65°C and it is continued by 30 min., then regulator switch off the fan and switch on the fuel shortage indicator.

In case of regulation repeated switching off, you should:

 >fill up the boiler with wood or to burn the boiler again if necessary

 > turn the thermostat handweel to the left as much as possible

 > wait until the fuel shortage indicator starts to blink

 > set-up boiler temperature using of thermostat handwheel

BOILER OVERHEATING

If boiler temperature achieves over 95°C, the regulator switches off the fan and switch on the boiler overheating indicator. Then you should:

 > wait until boiler temperaturegets down

 >remove boiler overheating reason
