Management & Maintenance
The Immersion heater.
In the ULMA LAMBDA BOILER there is a preconnected three-phase immersion heater of 6 kW.
When the immersion heater is used as back up, you set the thermostat of the immersion heater
so that it is not connected without a reason, it shall only be used when there is something wrong with the
burner or as support-run at very high energy needs in the house. Operating indication lights are shining
when the immersion heater is running.
Cleaning of the boiler
In the ULMA LAMBDA BOILER the maintenance
has been minimized i.a. by a well planned
construction and the large ash box holds approx.
48 liters. Ash emptying is made as required.
Cleaning of the tubes of the boiler is realized when
the flue gas temperature has increased approx. 50
degrees compared to a new swept boiler. More
frequent intervals give increased efficiency. The
giver should be cleaned at least once per month.
Giver for the flue gas temperature
Under the door on the top of the boiler, you can reach the tubes
at the regular cleaning of the heating surfaces
The tubes shown on this picture without the flue gas break that
you can see on the picture to the left.
O.B.S! Very important to put where flue gas in a proper manner after completion of sweeping.
See picture above.
Be extra attentive of to the quality of the pellets at new delivery or change of deliverer.
At new delivery a flue gas analysis should be made. Therefore we recommend a service agreement.
Contact your local installer regarding information of agreement.
The tubes of the boiler should be cleaned 4-5 times per year (may vary some depending on consumption
and pellet quality) or when the flue gas temperature has risen with approx. 50 degrees since previous
cleaning.
• Turn off the burner a couple of hours before service.
• Lift up the soot door on the top and clean the tubes. (Use the enclosed tube wisp.)
Check the colour of ashes in the tubes and inside the lid. Should be gray to light brown. Is the colour
black, the burner must be adjusted, otherwise it shorten the life of the burner. See dealer for adjustment
of the burner.
• Pull out the burner and clean from ash residues between the burner pipes at least two times per year.
NOTE!
Always be careful with ash since it might be ignited. The ash should be kept in fireproof vessels.
