any part of the boiler which is in contact with fire, warranty will be given for one year. For the pellet
burner warranty will run out after two years or after the consumption of 20.000 kg pellets, whatever
may occur first.
In case of damage we claim the right to check the installation and take a look at the damaged parts
before compensation.
None of our products may be used until they were set into operation by a Janfire authorised expert.
The protocol has to be signed by the expert and the customer. It has to be sent to Janfire AB.

Janfire will not give any warranty for faults concerning the hydraulic, the
electric installation or the flue gas system.
The boiler may not be used without adequate water pressure or without being
connected to the hydraulic - and the flue gas system.
Warranty will be lost by the use of not permitted fuel, insufcient draft, insufcient handling,
maintenance and no proper installation.
Warranty will be lost too, if changes or repairs are made without our permission.
There will be no responsibility for damages evoked by leakage water, corrosion, aggressive vapours,
dust, humidity (for example laundry dryer or washer in the boiler room), overpressure, assembly of

If a warranty claim was not justified, we will bring our costs to account.
3 Brief description / scope of delivery / allowed fuels
The usage of the Janfire Combiflame guaranties an environmentally friendly and economic operation
during heating. By the use of renewable fuels like wood pellets or log the heating is CO2-neutral.
Only the same amount of CO2 will be released to the atmosphere that the tree has collected during
its growth.
Advantages:
• good value combi boiler for heating and domestic hot water supply
• simple design and high performance
• can be used as an additional boiler to existing oil- or gas heating systems
• good isolation, causes only few thermal lost
• nominal heat output for pellets 20 kW
• only 15 Pa natural draft is needed
• easy to change from pellets into a log boiler and reverse
• easy to clean and maintain
The Combiflame is a steel boiler conform with EN 303-5. The combustion chamber consists of 5
mm sheets from ST35JR (EN10025). The outside of the pressure vessel consists of 3 mm. 100 mm

of high quality isolation material is used to prevent thermal lost. Powder coated sheets are used for
the cover panel. Cast iron is used for the grill and the handholds.
The connectors for flue gas, thermal relief valve and the water supply are on the backside of the
Combiflame. The boiler can be placed on 4 adjustable feet.
The Combiflame will be delivered including the catalytic converter, the Janfire pellet burner NH and
this manual.

Allowed fuel:
The Janre NH burner can burn pellets from 6 up to 10 mm. We specify pellets which are conform
with EN 14961-2 A1. If the boiler is changed into a solid fuel boiler untreated log up to a length of
log from about 50 cm and briquets of brown coal can be burned, too.
!
Other fuels are not allowed. Especially any kind of waist may not be used as
fuel.

5 Safety installations
During the assembly attention must be paid to the safety installations. Only safety parts which are
tested and labelled for safety may be used. Before setting the boiler into operation make sure that
all safety installations are in place and belong to the state of the art and work. If necessary check
them again. Especially the pressure relief valve, the thermal safety relief valve and the expansion
vessel have to be checked before the boiler is allowed to start running. All safety installations have
to be checked by an expert every year.
Safety installations are not part of the purchased parts package.
safety relief switch:
The safety relief switch is connected to the pellet burner. If the temperature of the boiler rises
above 95°C the safety relief switch stops the burner. The burner will not start on its own if the boiler
temperature falls below 95°C. You have to reset the switch by hand. Check the water pressure, the
hydraulic system, especially every pump, the heating controller and the sensors before resetting the
safety switch (DIN EN 303-5 clause 3.21). Please look at chapter 10, too!
thermal safety relief heat exchanger:
The Combiame has a welded thermal safety relief heat exchanger.
The thermal safety relief heat exchanger may not be used as a domestic hot
water supply.
This heat exchanger has to be used with a thermal safety relief valve which is tested and labelled
for safety.
Thermal safety relief valve:
The thermal safety relief valve has to open at 95°C. The assembly of the thermal safety relief valve
has to be conform to EN 303-5 clause 4.1.5.11.3. The valve must be placed in the cold water supply.
It is not allowed to have any other valve in front of or behind the safety relief valve.
!
Make sure that there is always at least 2 bar water pressure in front of the
thermal safety relief valve. It is not allowed to have any other valve in front
or behind the safety relief valve! The drain of the thermal safety relief system
has to be visible. The cross-section of any tubing concerning to the thermal
safety relief system has to be at least 15 mm.
It is not allowed to set the Combiame into operation without this safety system! The thermal safety
relief system has to be installed by an expert and checked every year.
Safety pressure relief valve:
The Combiame has to be equipped with a pressure safety relief valve which is tested and labelled
for safety. The maximal system pressure is 3 bar. The drain of the pressure safety relief system has
to be visible.
