INSTRUCTIONS FOR FITTERS
This boiler has been designed to heat water to a temperature lower than boiling point at atmospheric pressure.
It must be connected 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 qualified installer, check the following:
a) 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.
b) Make sure that the flue terminal draft is appropriate, that the terminal is not obstructed and that no exhaust gases
from other appliances are expelled through the same flue duct, unless the latter has been specially designed to collect
exhaust gas from more than one appliance, in compliance with current laws and regulations.
c) Make sure that, if the boiler is connected to existing flue ducts, these have been thoroughly cleaned as residual products
of combustion may detach from the walls during operation and obstruct the flow of fumes.
To ensure correct operation and maintain the warranty, observe the following precautions:
1. DHW
circuit:
1.1.
If the water is harder than 20 °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 flush the system after installation of the appliance and before use.
1.3.
The materials used for the product’s DHW circuit comply with Directive 98/83/CE
.
2. Heating
circuit
2.1. new system
Before installing the boiler, the system must be cleaned and flushed to eliminate residual thread-cutting swarf,
solder and any solvents, using suitable off-the-shelf non-acid and non-alkaline products that do not damage metal,
plastic and rubber parts. Recommended cleaning products are: SENTINEL X300 or X400 and FERNOX Regenerator
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 suitable
proprietary products as described in section 2.1.
To protect the system from scale, use inhibitors such as SENTINEL X100 and FERNOX protector for heating circuits.
Use these products in strict compliance with the manufacturers’ 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).
Failure to observe the above will render the warranty null and void
.
The following notes and instructions are addressed to installers to allow them to carry out trouble-free installation. Instructions
for igniting and using the boiler are contained in the ‘Instructions for Users’ sections.
Moreover, the installation technician must be qualified to install heating appliances.
Additionally, bear in mind the following:
