Please take into account the minimum safety
requirements, when installing a wood-burning
furnace H03/70-C with an open expansion tank.
When installing the radiators, ensure not to place
closures on the thermostatic valves of each section
on all the radiators. There must always be a fraction
of the installation (radiators) open for the furnace
to dissipate overheating or enable runaway.
It is mandatory to place an expansion tank (open
or closed) during installation.
During installation, it is advisable to set a minimum
thermostat to cut the circulator provided the
water in the boiler is below 50°C. This will prevent
condensation that occurs when the furnace is lit.
