- Ensure that the hydraulic pipes are not used as earth connections for the electrical or telephone system.
They are not suitable for this use and can rapidly deteriorate leading to serious damage.
- Before connecting up the boiler, flush, cleanse and dose all the system pipes to remove any debris that
could affect correct operation.
- If the water available for filling the system is hard (> 15 French degrees) or corrosive (pH < 7.2), a treatment
plant should be provided otherwise permanent damage can occur.
- If the mains water supply contains impurities, a suitable filter must be fitted.
- Avoid any accidental contact between the heating system water and the portable water as the former is not
drinkable.
After connection to the hydraulic system, ensure that the latter is completely de-aerated.
You are advised to insulate the heating system pipes to avoid heat dispersion resulting in increased fuel
consumption and environmental pollution.
20 ELECTRICAL SYSTEM
The electrical system must comply with the current regulations and be installed by professionally
qualified personnel.
Electrical safety of the equipment is ensured only when it is correctly connected to an efficient earth
system in compliance with the current safety regulations. The manufacturer will not be liable for any
damage caused by failure to earth the system.
Call professionally qualified personnel to check that the electrical system is suitable for the maximum power
absorbed by the equipment, ensuring in particular that the system cable sections are suitable for the
power absorbed by the equipment.
Adapters, multiple sockets and extension leads must not be used for general power supply of the
equipment from the mains.
For connection to the mains, a twin-pole switch must be provided in compliance with the current
regulations.
21 THE PROBLEM OF CONDENSATE
The water vapour contained in the products of combustion discharged from the boiler condenses when
the temperature of the water returning to the boiler is below 50°C. Condensation occurs in particular
when the boiler comes on in the morning after being switched off during the night.
The condensation is acid and corrosive and will gradually attack the boiler sheet metal panels.
To limit the formation of condensate as far as possible an anti-condensate pump must be fitted following the
diagram illustrated.
When the burner starts, a thermostat positioned on the water return to the boiler and set to 55°C with
exchange contact will start up the anti-condensate pump which will continue to operate until the set
temperature is reached; the thermostat will then simultaneously switch off the anti-condensate pump and
switch on the system pumps.
