6.2 - CHECKS BEFORE COMMISSIONING
Before commissioning the appliance, the following should
be checked:
- Make sure that the shut-off valves for maintenance on
the flow and return pipes of the system are open.
- Check the connection of the safety valves to the sewer
system.
- Make sure the boiler is powered electrically; the main
switch on the panel board must be on when placed at .
- Check the water pressure on the boiler pressure gauge
(see "heating system pressure"); for best operation, the
pressure should be between 1 and 1.2 bar (with pump
stopped).
- Make sure that the fan always runs at maximum speed
when the loading door opens.
- Check proper operation of the by-pass when the door is
opened, proper operation and seal with “door closed”.
Opening the loading door causes the fan to start up
automatically. In this way the flue gas accumulated in
the wood storage is extracted and conveyed directly to
the chimney.
The bypass, in conclusion, allows the flue gas to be
discharged to the chimney without escaping into the
room when loading the wood or during lighting.
Complete decommissioning
When the system is put completely out of service, hot
water production is fully deactivated.
In the event of putting completely out of service, disconnect
power to the boiler by opening the contact on the two-pole
switch upstream of the boiler and flicking the main switch
on the panel board to
0
: the indicator light will switch off.
Close the cold water and gas shut-off tap (if back-up boiler
with gas-fuelled burner is present).
ATTENTION!
The heating system can be effectively protected against
ice by using specific antifreeze products suitable for mul-
ti-metal plants.
Do not use car engine antifreeze prod-
ucts as they could damage the water
gaskets.
