DIVA SLIM PELLET BOILER STOVE
24
Plumbing layout 3 involves connecting the boiler stove to a heating system managed by one or more room thermostats.
These are connected to the terminal located inside the appliance’s left technical compartment. DHW will be generated by
means of a hot water cylinder fitted outside of the boiler and controlled by a temperature probe connected to the
appliance.
The three-way motor-driven valve, controlled by the pellet boiler stove, will manage heating of the system or hot water
cylinder, giving priority to the latter.
Setting “Menu 01 – Select season” to SUMMER allows for controlling the hot water cylinder only during summer (thus
with the heating system off).
PLUMBING LAYOUT “4” – Boiler stove connected to a centralised puffer controlled by an H
2
O probe connected to the
boiler stove.
Plumbing layout 4 involves connecting the boiler to a centralised puffer controlled by a temperature probe connected to
the appliance. The boiler stove will therefore operate only at the set temperature of the centralised puffer (“SET
PUFFER” can be set using buttons 1 and 2). In this type of system there are no room thermostats or three-way valves
connected to the pellet boiler stove.
Initial filling of the system
After the water connection of the appliance, fill the system as follows:
- Check the seal of all piping, the expansion vessel, and the circulation pump;
- Open the “automatic air release valve” on the appliance;
- Open the system load cock (mounted on the appliance) to load the system. Gradually allow the air to come out from
the appliance through the “automatic air release valve”; optimum working pressure is 1.5 bar (when the
appliance is operating);
- Vent all radiators and any other de-aeration systems to ensure that there are no air bubbles in the system.
After installation, check the seal of all plumbing joints for the first few days of operation.
The system and the water inside the boiler can be emptied by opening the “boiler body and system drain cock” situated
on the right side of the appliance.
