GENERIC PROHIBITION

It is forbidden to do/use the things indicated alongside the symbol.

GENERAL PRECAUTIONS

This boiler has been designed to heat water to a temperature lower than boiling point at atmospheric pressure. It must be con-

nected to a central heating system and to a domestic hot water supply system according to its performance and power output.

Before having the boiler installed by a qualied service engineer, make sure the following operations are performed:

• Make sure that the boiler is adjusted to use the type of gas delivered by the gas supply. To do this, check the markings on the

packaging and the rating plate on the appliance.

• Make sure that the ue terminal draft is appropriate, that the terminal is not obstructed and that no exhaust gases from other

appliances are expelled through the same ue duct, unless the latter has been specially designed to collect exhaust gas from

more than one appliance, in compliance with current laws and regulations.

• Make sure that, if the boiler is connected to existing ue ducts, these have been thoroughly cleaned as residual products of

combustion may detach from the walls during operation and obstruct the ow of fumes.

• The use of a chimney liner is required for condensing boiler.

• To ensure correct operation and maintain the warranty, observe the following precautions:

1. DHW circuit

1.1 If the water is harder than 15 °F (1 °F = 10 mg calcium carbonate per litre of water), install a polyphosphate dispenser or an

equivalent treatment system, compliant with current regulations.

1.2 Thoroughly ush the system after installation of the appliance and before use.

1.3 The materials used for the DHW circuit must comply with Directive 98/83/EC.

2. Heating circuit

2.1 New system: Before installing the boiler, the system must be cleaned and ushed to eliminate residual thread-cutting, swarf,

solder and any solvents, using suitable off-the-shelf non-acid and non-alkaline products such as Sentinel X300 or Fernox F3

that do not damage metal, plastic and rubber parts. To protect the system from corrosion, sludge and scale, use inhibitors such

as SENTINEL X100 and FERNOX protector for heating circuits. Use these products in strict compliance with the manufacturers’

instructions.

2.2 Existing system: Before installing the boiler, drain the system and clean it to remove sludge and contaminants, using suit-

able proprietary products. Recommended cleaning products are: SENTINEL X400 or SENTICLENE 8500 (ideal for unplanned

emergency cleans) and FERNOX regenerator for heating circuits. Use these products in strict compliance with the manufactur-

ers’ instructions. Remember that the presence of foreign bodies in the heating system can adversely affect boiler operation (e.g.

overheating and excessive noise of the heat exchanger).

If heating systems are to be operated at lower than normal temperatures (>60C) to accommodate under-oor heating require-

ments etc then consideration should be given to the use of a long lasting biocide such as Sentinel Senticide 7500 or Fernox AF10

to prevent microbiological activity.
