4.5 Installing the boiler
NOTICE
Reduction in performance due to air leakage
The use of flanges without sealing cords can result in a reduction in performance
due to air leakage
Therefore:
❒ sealing cords or the surface sealant provided must be used on all the flanged
connections on the following components: loading; ash removal; pressure
ducting; air ducts for primary, secondary and tertiary air; ducting for combus‐
tion air fan; flue gas and flue gas return piping.
4.5.1 General information
Front and back of boiler
The front of the boiler is its operating side. All of the elements necessary for operating
the unit, e.g. combustion chamber, burning chamber and ash can can be found on the
front.
The back of the boiler is opposite the front and is where the stoker unit, EOS drive and
complete flue gas system can be found.
Heat exchanger on the left or right
A general distinction is made between whether the heat exchanger is located to the
left or right of the combustion chamber (as seen from the front = operating side). It is
important to determine whether the heat exchanger will be installed to the left or right if
there is no existing layout plan.
The following images show the instructions for installing a heat exchanger to the right
of the combustion chamber. If it is to be installed to the left, the steps should be car‐
ried out in the same way but on the other side.
4.5.2 Bolting together the combustion chamber and heat exchanger
❒ Position the combustion chamber as per the layout plan ensuring it is level.
❒ Weld the nuts (M12) on the grate shaft of the heat exchanger
