– Cleaning the interior of the boiler
Additional cleaning
For every 1300-1700lbs (600-800kg) of pellets consumed, additional cleaning should
be performed.
For the back boiler, the procedure includes cleaning the air flow pipes and
turbulators. To do this, open the lid on the top of the unit (Figure 27 a), remove the
galvanized plate and the six wing nuts securing each turbulator set (Figure 27 b and
c). Then pull the turbulators up (Figure 27 d/e). Use a vacuum cleaner to clean this
area (Figure 27 f). Clean the interior of the tubes (Figure 27 g) using a steel brush
(Figure 27 g). The removed turbulators should also be cleaned using a steel brush
(Figure 27 h).
To reassemble the turbulators, perform the steps above in reverse order of the
figures below.
