INSTALLATION M-CS
According to Danish laws and regulations this boiler must be connected to a system
with “open” expansion tank. Please check you local regulations
General
The expansion tank must be able to contain at least 4 % of the total amount of water
in the heating system. Should the plant be installed with an accumulation tank, then
the expansion tank must be able to contain at least 8 % of the total amount of water
in the heating system.
The boiler must be in non blockage connection to the expansion tank (You must not
be able to block the pipe between)
Should the open expansion tank be placed in a not frost safe place, the tank itself
must be protected against frost. The circulation to the tank may be controlled by a
thermostatic valve or similar in order to secure, that the boiler water is getting
minimum access to oxygen.
Connection of auger from extern fuel silo
See diagram no 3
The auger must give a certain amount, compared to the boiler type. See table below.
If you try to enter an amount which lies outside the area listed in the table, the control
unit will write “Error in weight”. It is described in section 2 in the Users guide how to
weigh the fuel amount and key it into the control unit.
Permissible fuel amount for auger
Boiler type
Auger Kg/min
M20i-CS
0,8 – 11,5
M40i-CS
1,4 - 19
M80i-CS
2,2 - 32
The connection must be made with a flexible hose. The auger must not support on
the stoker unit and vibrations from the auger must not be transmitted to the stoker
unit.
In case the plant is connected to a silo placed at the loft above you should also use a
flexible hose, which must be emptied after each filling. The hole through the ceiling
must be made fire-proof.
Connection of the sprinkler
The sprinkler system for the boiler must be under constant water pressure from a ½
inch tap with a safety faucet and be connected to the dirt collector under the pressure
tank.
Please make sure, that pipes / hoses are free of dirt or metal shavings.
You must test the system, when it has come under pressure.
The easiest way to test the sprinkler system is to unscrew the hose from the
thermostatic valve to the auger channel. Then press the red cap under the valve to
activate it
After testing the sprinkler system it is important to check that the valve is closing
properly! (Dirt ore the like, in the valve seat, can prevent this)
