In order to totally eliminate the problem, the above circuit must be correctly adjusted in order to
maintain the boiler constantly at 55°C even at night and a further temperature-limiting thermostat must be
added to prevent the system mixing valve from sending water below 55°C to the boiler.
This will ensure long life of the boiler.
The flow rate of the anti-condensate pump is normally 25%-30% of the system pump flow rate, whereas
the head required is not particularly high as it only has to overcome the resistance of the boiler and the
valves.
The flue collector of the TRISPACE AR boilers is provided with a fitting for discharge of any condensation
that forms during the start-up phase.
Do not connect the fitting directly to the mains drainage system but to a collecting basin in order to monitor
condensation.
For accurate monitoring, check that the condensate forming in the flue does not also end up in the
basin.
The condensation is acidic and corrosive and will therefore contaminate if discharged into the mains
drainage system.
Before emptying the basin into the mains drainage system, the acid level must therefore be restored to
between pH 6.5 and 9 using neutralising products.
22 FUEL SUPPLY
The fuel supply line must comply with current regulations and be laid by professionally qualified personnel.
Before installation, you are advised to thoroughly clean the inside of all the fuel supply pipes in order to
remove any debris that may affect correct operation of the boiler.
Check the fuel supply system internal and external seal.
If using gas, the connections must be perfectly sealed.
Check that the fuel supply system is provided with the safety and control devices prescribed by the current
regulations.
Do not use the fuel system pipes to earth electrical or telephone systems.
Check that the boiler is pre-set for operation with the type of fuel available.
