STARTING UP THE BOILER
6.1
Prior warnings
Repair and maintenance of the module must be carried out by a qualified professional, authorised
by
DOMUSA TEKNIK
. For optimum functioning and conservation of the boiler, it should be serviced
annually.
Please carefully read this instruction manual and keep it in a safe, easily-accessible place.
Before any servicing, disconnect the boiler from the mains and cut off the gas supply. Any
manipulation of the sealed parts of the boiler is prohibited.
DOMUSA TEKNIK
will not be liable for any damages caused by failure to follow these instructions.
6.2
Filling the domestic hot water tank
The hot water tank must be filled before filling the heating circuit. Open the flow of domestic hot
water to the hot water tank, and turn on a hot water tap in the installation. When the tap begins to
run freely, turn it off, as this means the hot water tank is full.
6.3
Filling the heating circuit
The
Fusion Hybrid Gas Condens
module is equipped with a filling disconnector. The heat pump
(external unit) includes a manual drain valve on the upper part of the heat exchanger flow tube
(condenser). Open it during the filling process and wait for the water to start running (please refer
to the operations manual of the
DUAL CLIMA
heat pump). The air should also be bled from the rest
of the installation using the air bleed valves provided. The filling must be carried out slowly,
thereby facilitating air evacuation from the water circuit. Once the installation is full, close the
disconnector valves.
The
Fusion Hybrid Gas Condens
module have a pressure sensor for controlling the pressure of the
installation. If it drops below 0.05 MPa (0.5 bar), a low pressure alarm ("
E02
") will appear on the
display.").
: Turning on the module or the heat pump without water may cause serious damage to
the equipment.
6.4
Gas connection
For the installation of any type of gas, the installer must be authorised by the Ministry of Industry
and strictly follow the applicable Gas Regulations. The gas installation must comply with the Gas
Installation Regulation (RIGLO).
However, the following recommendations must be complied with, at the least:
- Before installing the gas pipes, check the type of gas is compatible with the boiler.
- Check that the gas meter in the home can measure the rate of gas supply required.
- The gas pipe diameter is not determined by the boiler connection. It should be calculated in
accordance with its length and consequently its pressure drop.
- The pipes must be directly connected to the main gas supply pipe, not connected in parallel to
other gas appliances.
- Check there are no leaks from the installation.
- The gas supply company is the sole responsible for connecting the gas meter to the gas
