IMPORTANT PRE-INSTALLATION NOTES
Before installation, it is imperative that the following guidelines are heeded to ensure the trouble-free and efficient operation of
the boiler:
Siting
The water heater should not be installed in a shower compartment or bathroom.
When siting the boiler, consider the potential requirement for future access to the cold-water inlet. The supplied in line filter
should be cleaned either on an annual basis or when a reduction in water flow is noticed.
The cold supply should have an isolation valve close to the appliance.
Power Supply and Wiring
The power supply to the premises must meet the minimum requirements of the unit being installed, with special attention paid
to the supply current, cable size, and RCD recommendation. The supply voltage to the appliance must never drop below 207
Volts.
To keep the casing clean, switch ‘OFF’ the water heater at the electrical supply, and simply wipe with a damp cloth. DO NOT use
abrasive cleaning fluids as this may damage the stove enamel paintwork.
