GENERAL RULES AND RECOMMENDATIONS WHEN USING A COOKER
1. Before the construction of the installation it is recommended that the heat
losses be calculated by a specialist for the concrete case.
2. We recommend that the stove be connected to an open heating system, but
when connected to a closed system, it must be protected by a safety hydraulic
valve set at 2.5 bar.
3. To ensure deaeration of each branch and element of the installation at any
time of its operation.
4. All elements of the installation must be ensured against freezing, especially if
the expansion vessel or other parts of it are located in unheated premises. If
it is impossible to ensure non-freezing of any part of the installation,
propylene glycol has to be used instead of coolant water.
