INSTALLATION
Connection to the heating system
See diagram 2
The boiler must be connected as shown in diagram 2 or as demanded by local
statutes.
Further information is in the user manual, section. 7
The minimum amount of water passing through the boiler must be (see table)

Water returning to the boiler must always be
min. 60°C
If the above is not adhered to you will risk increased tear of the steel in the
boiler, resulting in a shorter life expectation for the plant.
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 must be
controlled by a thermostatic valve or similar in order to secure, that the boiler
water is getting minimum access to oxygen.
Connection of the sprinkler
The sprinkler system on the fuel store 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)
By an extended auger channel (750 mm) we deliver the sprinkler system
separately. The sprinkler including pressure tank must be fitted on the wall next
to the auger channel.
