recycling depot.
We do not assume any liability for any malfunctions resulting from the use of non-genuine Janfire
Components.
This particularly applies to control units, external materials handling equipment and fuel pipes from
other manufacturers. We also do not assume any liability for operational difficulties resulting from
inadequate hydraulic and/or exhaust gas systems. We reserve the right to make technical changes.
Permissible fuel
It is only permitted to operate this pellet boiler with fuels that comply with the Federal Emission
Control Ordinance (wood pellets manufactured from natural wood).
Permissible pellets have a diameter of 6mm or 10mm. The pellets must comply with the EN-Plus
standard or the PVA standard (Austrian Pellet Association). The fine fraction (proportion of pellets
with a length
of less than 10mm) is not permitted to exceed 8% in the pellet hopper. The volume density must be
less than 0.75kg/l. Other fuels, in particular pellets that contain recycled materials, may not be
used.
The specified cleaning interval applies to pellets that comply with the EN-Plus standard.
For reasons of operational safety and environmental protection the use of fuels other than
pellets that comply with the EN-Plus or EN 14961-2 Class A1 standards is not permissible.

Operating Instructions Janfire Pellet boiler Integral Typ 25
The Janfire pellet boiler is designed to burn wood pellets in a safe, easy-to-use and
environmentally friendly way. The boiler has ten vertical tubes which effectively cool down the flue
gases and through thermal convection raise the temperature of the water. The tubes are also
equipped with retarders. 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

Operational Description
General operation description
An external auger feeds pellets from an pellet store via flexible drope tube and in to a receptacle in
the burner (internal storage). An internal dosage auger then feeds the pellets to a drop shaft where
they fall freely into the combustion chamber; this eliminates the possibility of reverse combustion.
A fan feeds the burner with primary and secondary air. On its way to the burning cup the air cools
heat-exposed parts of the burner effectively warming up the incoming primary and secondary air. A
specific amount of air is fed into the combustion cup for primary and secondary combustion. The
ignition coil preheats the air for automatic ignition. The thermometer (flame guard) notes when the
pellets have ignited. If ignition does not succeed then the burning cup is automatically cleaned and
a new attempt is made. If ignition still does not successful then the burner is shut down.
If the airflow is insufficient then the hot flu gases will rise in the drop shaft. The burner control will
register this rise in temperature with an temperature sensor and the burner will compensate by
reducing the effect, thus eliminating the risk for reverse combustion. When this takes place the
control lamp changes colour to yellow to indicate that the system is running in backup level and
”Low chimney flow” will appear on the display screen.
If the temperature drops to normal levels the burner control will return to normal operation but will
continue to illuminate the yellow light warning of draft problems in the boiler or chimney.
If the temperature in the drop shaft still rises and reaches the highest limit, then the burner will shut
down.. The control lamp will turn red and “Overheated” will appear on the display screen.
The burner output can be set in the burner control operator menu and is determined by the desired
level of heat required, set between 6kW and 25kW (factory settings and permissible min/max level
can be adjusted by the installer) Burner output is adjusted in 1kW steps and is governed by the
burner thermostat sensor. In addition an optional pilot operation will continue to maintain
combustion until further heat is in demand.
The pellet feed rate at a given output is automatically adjusted when the lambda sensor is installed.
Otherwise the volume weight of the pellets is entered into the burner control in order to allow the
burner to adjust the pellet feed rate. The volume weight is typically 675 g / litre with energy content
of 4.8 kWh / kg.
In order to secure power and combustion in use of pellets with another volume weight or energy,
change value of the volume and energy and pellets.
Optimal burner performance can also be controlled with the (optional) installation of temperature
sensor PT100, allowing the burner to automatically modulate up or down in relation to the heat
demand. Alternative to using the modulation function the burner will operate between min and max
temperature settings, heating until the desired temperature has been reached at the boiler
thermostat.
32580002_ EN_ver4
 Janfire 2014
18(45)
Operating Instructions Janfire Pellet boiler Integral Typ 25
High quality pellets produce high efficiency and effect. High quality pellets are solid wood pellets 610 mm with little sawdust. Moisture levels should be no higher than 12%, ash content no higher
than 1% weight, and energy content should be about 4,7 and 5,0 kWh/kg. Make sure you see a
content declaration for the pellets on delivery..
The burner has a patented moving grate in the bottom of the combustion cup which scrapes away
soot and ash residue into the boilers firebox. This ensures the combustion grate holes are kept
clean to maintain the burner performance. The burner automatically cleans itself according to a
signal from the boilers thermostat or from pre-programmed intervals (use of pellet) Additionally the
boiler tubes are swept clean according to the thermostate and the time period set in the boiler
control.
Thermo switch in the upper part of drop shaft breaks power to burner if the temperature
there exceeds 70°C. Manual reset through breaking power to burner, wait until
burner cools down and connect the power again.
A micro switch prevents the
burner from operating when
detached from the boiler
bulk head.

5.2 Modulated power regulation
Contact for
temperature
sensors
In order to be able to use the modulation function a Pt100 sensor connection is provided on the
side of the burner..
The aim of this function is to save on fuel consumption and enhance operational efficiency while
reducing the number of cycles per hour. Janfire's intelligent control system monitors the heating
system demand trends and modulates the boiler output accordingly. This makes for quick and
smooth response at maximum output when the demand is high and progressively drops and settles
on low output when the heat load is nearly fulfilled. temperature decreases in the boiler.
Difference of objectives temperature is set at +7 ° C to the regulation should have a little larger
area to work in. It is at this temperature field burner to work best in. If or when the temperature
comes up for the higher limit (when the heat consumption is lower than the Burner's lowest power)
breaking the operation and the burner goes into standby or maintenance.
32580002_ EN_ver4
 Janfire 2014

Operating Instructions Janfire Pellet boiler Integral Typ 25
The burner will restart the combustion operation again when the lower temperature limit (3C lower
than target temperature) has been reached. Boiler temperature hysteresis is 10C from maximum
target temperature (-3 C to +7C from target)
When using the mody modulation function please set the boiler operating temperature above the
+7C maximum level.
If the PT100 temperature sensor is not connected to the burners control unit then the control will
revert to the boiler thermostat and the system will operate using the set permanent set output level.
If there is no boiler thermostat then breaking the operation and alarm "ERROR " are available.
5.3
Gliding boiler temperature in function of outdoor temperature
This function regulates the temperature in the boiler depending on outside temperature as follows:
Warmer outdoors lower boiler temperature and vice versa. Colder outdoor temperature create
higher boiler temperature.
In this way boiler temperature is adapted to outdoor temperature fluctuations during the day and
during season cycles.
With an outside temperature sensor type Pt 100 linked to the burner, the temperature is regulated
in the boiler as follows:
+20° C or higher out----60° C boiler temperature
-20° C or less absent -----90° C boiler temperature
For outdoor temperatures between the specified limits obtained a sliding boiler temperature target
value so, for example, at 0 ° C is target 75 ° C.
73 ° C [72 → 75 ← 82]
In the above example:
-- 73 - current boiler temperature
-- 75-calculated target temperature (gliding target value)
-- 72 - temperature thermostat switched on at the current target temperature (this is 3 ° C for target
value)
-- 82 - temperature of the thermostat off at the current target temperature (7° C above target value)
The outdoor temperature average value is calculated by measuring the outdoor temperature over 5
minute intervals. This is compared with the the previous value and once considered the boiler
temperature is adjusted. Boiler temperature target value is adjusted 1C per interval whether is is
measured greater tolerance than 1C.
When the estimated target temperature approaching 90 ° C, the temperature limit for the
thermostat off is adjusted to a maximum of 92 ° C. It is only +2 ° C above at 90 ° C although it is set
to +7 ° C above target temperature thus the control system ensures optimal performance and
protects the boiler from overheating .
Identical level of control features exist for the low level limit which is restricted to 55C.

Burner Maintenance
Thanks to a new patented technique the Janfire NH Pellets burner has the least need of
maintenance of all pellets burners on the market. The burner can run for 6 months at a time without
maintenance (applicable for burners mounted on Janfire boilers). When mounted on an existing
boiler the ash handling varies depending on the size of the boilers ash container.
CAUTION
Breakdown
For optimal and safe operation it is important that all adjustments of the burner’s operational
parameters are correct. We recommend that you sign a service agreement with your retailer.

weighing. To change; scroll the “menu” button and change the value be pressing the “+” and ““buttons. Save the new value by pressing and holding down the “menu” button for 3 seconds
If the boilers thermostat is on, then the internal storage is filled (approx. 2 min.) if the pellets level is
below the sensor. The burning cut is then cleaned. The start sequence then begins. Pellets are
feed in, the ignition spiral warms up and the fan starts. The start sequence is pre-programmed to
deliver a fast ignition and exhaust levels as low as possible. The start-up runs for about 10 minutes
after which the chosen effect level begins.
6.8 Starting the Burner after the Installation
NOTE It is important that when starting up for the first time that the internal storage and the dosage auger are
full with pellets.
1. Switch on the power to the burner. After 2 minutes the external screw starts. The feeding stops
after 2 minutes. If the internal storage is not filled within 2 minutes press the “ON/OFF” button
and the auger will continue to feed. Continue this process until the correct level is reached.
When the internal storage is full a sensor stops the external auger.
