EQUIPPED

The stove comes with a few accessories to facilitate its
installation and also so that the plumber can do his job
in compliance with current standards.
V.S. = Safety Valve DN ½"
The V.S. drain must be externally connected with a
drainpipe which drains.
T.R.V. = DN 3/4'' thermal relief valve with remote
bulb-type probe.
The purpose of the thermal relief valve is to deliver cold

inside the boiler. This helps take away part of the excess
heat.
The probe of the valve is inserted in one of the
compartments on the front of the stove.
The thermal relief valve is to be connected to the mains
water supply, while the dissipater outlet runs outside the
building into an open drain.

bubbles of air from the stove circuit during installation and
periodically when necessary.

PRELIMINARY CHECKS PRIOR TO LIGHTING

The above check must always be made:
At the beginning of each winter season;
After a long time that the stove has not been used;
This will ensure that the stove is not lit if there is little or no
water which could cause the stove to become deformed
or even break.
Note: If the pointer on the water gauge is on 0 (zero),
leaks in the system
the water has not been topped up.
If you have any doubts, call your usual plumber.
Before stove commissioning make sure that the
thermostatic valve is completely opened (maximum
turned to right). You can record the valve position using
the knob placed in the technical compartment under the
stove (- 8.1 -).
