Prerequisites for installing a pellet boiler105.3 Flue gas systemThe flue gas system consists of a chimney and a flue gas tube. The flue gas tube connects the pellet heating system tothe chimney. The chimney leads the flue gas from the pellet heating system out into the open.1. Design of the chimneyThe dimensions and design of the chimney is very important. The chimney must be able to ensure sufficient draft tosafely draw away the flue gas regardless of the status of the boiler. Low flue gas temperatures can cause sootingand moisture damage on chimneys that are not insulated. For this reason moisture-resistant chimneys (stainlesssteel or ceramic) should be used. An existing chimney that is not damp-resistant needs to be rennovated beforeuse. Follow guidelines below:Boiler size PE(S) 12 – 20 PE(S) 25 – 32 PE(S) 36 – 56Flue gas tube diameter (at boiler) inch/mm 5/130 6/150 7/180Flue gas temp. / rated power °F 320 320 360Flue gas temp. / partial load °F 212 212 230Min. draft – full load/part load in/wc 0.03/0.01Chimney size Min.

Selkirk sure tempb. Supervent (JSC)c. Security chimneys (secure temp ASHT)Use heavy gauge (26ga or better) black smoke pipe to connect to existing chimneyUnregulated combustionPlease observe that combustion air openings and flue pipesare not reduced in size or closed. Make end user aware ofthese guidelines and their potential danger.Clean the chimney and the flue gas tube at regular intervals.Check if the draft inducer is clean and in a good condition.2. Flue gas temperatureThe flue gas temperatures are the same for all boiler types:The dewpoint of flue gas with wood pellets (max. 10% water content) is approx. 120°F.It is possible to increase the flue gas temperature to prevent condensation inside the chimney and avoid damagedue to damp. Only authorised specialist personnel may increase the flue gas temperature.NoteThe increase in flue gas temperature results in reduced efficiency and thus increases fuel consumption.Operating Manual PE 12-32 PE 149 USA 4.1
