Re: Use of burner to burn wooden pellets type Woody, Scotte, Bio-comfort and
Boink in boiler equipment in relation to smaller, closed facilities in compliance with Work
Supervisor Regulations for Hot-water Heating Systems. (publ. 42/1980 para 4)
With regard to your query of 1 September 2006 concerning the use of the burner to burn wooden
pellets type Woody, Scotte, Bio-comfort and Boink in boiler equipment in relation to smaller,
closed facilities with pressure expansion, we can report that the Work Supervisor has perused the
submitted materials and can declare that the burner for wooden pellets type Woody, Scotte, Bio-
comfort and Boink can be installed in the heat facilities listed in paragraph 4 of the Work Supervi-
sor publication no. 42/1980, Regulations for Hot-water Heating Systems.
It is assumed that the boiler contains the requisite amount of water and that the entire heating fa-
cility is designed in exact compliance with the instructions given in publication 42/1980, and also
that the electricity supply will only be connected to a boiler with a fitted and connected thermostat
with the appropriate overheating safety fuse which must be manually reconnected after activation.
All heating in the boiler must take place by means of the pellet combustion chamber, and only
fuels listed in the instructions may be used. Otherwise the equipment must be installed with an
open expansion (compare paragraph 2 in publication 42/1980).
This decision is based on the enclosed instructions and diagrams, Test Report no. 300-ELAB-
0741, as well as the Power Dropout Test with readings recording the build-up of heat in the boiler
if the power supply to the equipment is interrupted.
Best regards,
G.Agersnap
