ULMA AB reserves the right to changes in details and specifications without a preceding message.
Information
• Keep this manual so that it is accessible to professionals and future needs.
• Read this manual carefully before putting the pellet burner into service.
• Follow the manual and its instructions carefully and do recommended management and maintenance.
Registration to the local building authority in your municipality
N.B.: At every change of heating system, the local building authority of the municipality has to be contacted
and a so called “Construction Registration” is made.
Inspection
Heating plants installed today shall be inspected and approved by authorized inspector like the local certified
chimney-sweeper. The local building authority in the municipality can inform you how this could work.
Important at installation
• Run the feed auger of the burner by itself until the pellets start to come in constant flow. This can be made
by connecting the feed cable of the burner directly to the cable of the auger. Run the auger approx. 15min
after the first pellets have reached the outlet on the auger.
• The auger shall have a max angle 45 degrees and not be below 43 degrees.
• We recommend that the length of the hose, between the burner and the auger, should not be below
500mm. The auger shall also be placed so that it sits a little to the side of the tipping chute of the burner,
this to avoid that pellets can fall down into the burner if back burning would occur when the hose burns off
as a part of the safety.
•. The start dose shall be weighted and have a weight of about 130gram or a volume of approx. 2 dl. Less
quantity gives problems at ignition of the fuel and can create wood-gas in the hearth of the boiler that then
gives wood-gas puffs if, when the fuel is ignited in the burner. Larger quantity make the effect calculation
of the burner not correct and the parts of the burner get a shorter life time if it is run on too high effect. This
is important since ULMA AB does not compensate burners that are incorrectly installed on the warranty
part.
• At adjustment of the burner, the draft limiter should be adjusted after the draft conditions of the chimney.
• The feed cable of the burner shall be connected above the overheating protection of the boiler.
Sweeping
Chimney sweeping shall in accordance with the fire-protection law shall be made frequently during the year.
This is made by your local chimney sweeper. Regular cleaning of heating surface of the boiler shall be made
in a way so that good operating economy is obtained. Prepare sweeping by turning off the boiler at least a
couple of hours before cleaning to minimize the amount of glowing ash.
Warning!
See to that the power to the boiler is turned off before the cover over the burner is removed and dismount
cabling to the burner when the burner is removed from the boiler.
Maintenance agreement increases operation length and life of the burner
ULMA AB recommends subscription of annual maintenance agreement.
For more information contact your local ULMA retailer.
Change of wear parts
ULMA AB always recommends that wear parts, when needed, are being changed by an authorized service
technician at your ULMA retailer. Ulm
a’s retailers can provide necessary spare parts and at change make
sure that the parts being changed on the unit go through alignment and that a flue-gas analysis of the unit is
made.
