valve should be checked up at certain intervals. As it has already been said, one end of the
thermal safety valve is to be installed onto the boiler exchanger, while the cold water under
pressure is supplied to the other end. It is particularly important that the flow of that water is
unobstructed even during power cut.
If it is not possible to ensure supply of cold sanitary water even during power cut, it is
mandatory to connect the boiler to an open system.
3.3 Positioning of the Ecoflame Plus boiler in the boiler room
Boiler room must be secured from freezing.
The support surface for the boiler in the boiler room must be of non-combustible material. Recommended
distances of all four sides of the boiler in relation to the boiler walls or other solid body (buffer, etc.) are
shown in

. These distance values allow a safe access when firing, sufficient space for cleaning
and unobstructed access to the fan and valve for filling and drainage. Boiler at its left hand side should be
at a distance of 400mm from the wall. The space behind the boiler is important for assembly into the
hydraulic system and for potential removing of the system for electric firing.
Boiler room must have
sufficient ventilation holes both for fresh air and for the outlet of the exhaust air.

Total area of these openings is minimum 150cm² for powers up to 50kW, while for the power over 50kW,
the area must be bigger for 2cm² per kW.
