INSTALLATION
6.1
Installing the boiler
The installation must be done in accordance with all local and national codes, regulations and standards, and in accordance with the directives of
all relevant authorities.
1. The boiler must only be installed in an area where it is allowed to install it.
Make sure that this area is protected against the danger of freezing.
2. The area should have sufficient ventilation and cooling to prevent overheating.
3. When delivered the boiler is on a pallet.
Install the boiler on a flat non-combustible floor and level it by using its positioning bolts.
4. A minimum free space of 50 cm should be left on each side of the boiler for service access.
5. Remove the sealing/protection caps from the connection tubes.
Warning : take care as residual water from testing may drip
6. Fill the condensate trap with clean water.
This can be done by flushing some water into the cast aluminium exhaust connection from the rear.
This water will then drain into the syphon and fill it.
6.2
Frost protection
The boiler is protected against frost.
If the boiler detects an NTC flow temperature below 8 ºC, the CH-pump will be activated. If temperatures continues to fall the boiler will start at a flow
temperature of 6 ºC and it will run on minimum load until the flow NTC senses a temperature of 15 °C. The CH-pump will stay running for another 10
minutes. This only protects the boiler and does not protect the installation, pipework or radiators against freezing.
During longer periods of absence in the winter, the installation itself should be protected by activating the heating periodically and by partly
opening the radiator valves.
Where a room thermostat is controlling the demand, do not set the room thermostat to a value below 15 °C.
To protect frost sensitive radiators against frost it is possible to connect a frost thermostat in parallel with a Volt free room thermostat.
It is also possible to set the CH pump to activate automatically under OTC settings when an outdoor sensor is present (this must be set by the
installer). In this case,the CH pump will be activated if the outdoor temperature drops below 8 ºC.
