DANGER
Risk of burns
Note The free space around the Janfire pellet boiler should be in accordance with local regulations
(council planning department).
The boiler room should meet the requirements of the fire authorities. Contact a qualified local chimney
sweeping contractor.
The burner is equipped with a safety cut-out that prevents operation of the burner with the burner
desmounted. The boiler door is locked with a sturdy nut and cannot be open without tools. Always
disassamble the burner before the boiler door opening to prevent the burner to start involintary on the outside
boiler.
The temperature limited, valve and safety valve 9 bar should always be installed.

3 General
The Janfire pellet boiler is designed to burn pellets in a safe, easy-to-use and environmentally friendly way.
The boiler has ten vertical tubes which effectively cool down the flue gases. The tubes are also equipped with
turbulators. The boiler is equipped with a large door. The door has a prepared hole suitable for installation of
the burner. When the door is opened the burner remains on the door. This makes it very easy to clean the
combustion chamber and burner. The door is also equipped with a safety cut-out which stops the burner
when the door is opened.
Recommended boiler temperature:
Winter: 85 ˚C +/- 3 ˚C
Summer: 83 ˚C +/- 3 ˚C
Note Pellet quality EN 14961-2 Class A1 is recommended.

If a previous boiler had a lower flue connection, then seal up the old hole and make a new hole at the right
level. The Janfire pellet boiler flue is shaped like a T-tube. The T-tube allows the boiler to be connected from
the sides or straight backwards. Assemble the draught limiter in the free hole, which gives the boiler a stable
draught and prevents condensation.

4.3 Boiler
The Janfire pellet boiler can be supplied ready-assembled with a shunt as option. The boiler has a large
water volume (180 litres) and does not need to be connected to a storage tank.
In other cases where the storage tank shall be used, connect it with the connections on the backside.
Plug and socket for connecting to power, circulation pump and burner are supplied.
The soot sweeping mechanism is mounted under the cladding on the left side.

Note Before starting the boiler ensure that the system is filled with water, that electrical
connections are correct and that pumps are functioning.
Note The tube system should be rinsed out before the boiler is connected in order to avoid
damage from contamination to pumps and valves.
4.4 Burner
To install the burner see the burner’s installation instructions below.
4.5 Filling with Water
Filling with water should be done using a fixed connection to expansion connections or with the help of a pipe
in the drain valve.

Start the circulation pump when the system is completely filled with water.
4.6 Ash Removal and Sweeping
During normal use (6-8 ton per year) of pellets of EN Plus class 1 the maximum interval for ash check and
cleaning is 10-12 months.
1. Stop the burner, see burner instructions.
2. Wait for approximately 30 minutes until all the pellets are no longer glowing.
3. Open the door of the combustion chamber. Remove the baffle plate (see Figures)
DANGER
Risk of burns
Note The boiler and burner can still be hot.
4. Clean out the ash. The Janfire ash can makes the job easier.
5. Open the upper hatch (see Figure) above the tubes and take out the spirals.

6. Use the sweeping brush to clean the ten tubes.
7. Reassemble the spirals and screw down the upper hatch.
CAUTION
Breakdown
Note Do not forget to clean the boiler flue so that ash does not prevent the smoke from going out
into the chimney.
4.7 Using the Automatic Sweeping
Cleaning mechanism starts automatically after a selectable time intervals.
If the boiler is not equipped with automatic handle sweeping then you should manually use the sweeping
handle (OBS Option) at least once a week. Pull the handle quickly 3-5 times on each occasion.
