OPERATION WITH ONE MODULE ONLY
If only one of the two modules is permanently working, it is recommended to electrically and hydraulically shut off the module
not working, by working the switches (disabling burner, pump and sludge drainage) on the panel and working the ball valves that
shut off the pump and the corresponding steam outlet valve.
ELECTRIC CONNECTIONS
The generators come with electric panel (IP 55 protection class) fully assembled to the various boiler accessories.
Wiring diagram
See the diagram inside the electric panel.
CHIMNEY
Chimneys must be sized according to current standards in the country of use.
BOILER
This generator has a low water content and can be used in those applications requiring a constant steam outlet.
In order to better follow users' requests, recommended burner should be two-stage or modulating ; in order to avoid excessive
level changes resulting from sudden outlets that would lead to boiler erratic operation.
Furthermore, especially when running on methane gas, there is a long combustion chamber “pre-flushing” with air every time the
burner restarts and this cools down the small quantity of water in the boiler, thus causing a rapid pressure drop. This is why we
recommend to reduce burner stops as much as possible using one of the above-specified types of burner.
MATCHING BOILER AND BURNER
Make sure that the gaps between nosepiece and door are duly filled with flame-proof ceramic insulating material.
The strip of ceramic insulating material supplied as standard with the boiler must be wrapped around the nosepiece for at least
one full turn in order to protect burner flange from the flame. It is not necessary that the ceramic insulation material fills the gap
up to the door insulation inner surface.
