Part 1
– Introduction
The
is a high efficiency gas wall boiler and is designed for heating a central heating (CH) system
and producing domestic hot water (DHW).
The main functions of the
boiler are:
1.) Heating the house: Central Heating (CH)
2.) Producing Domestic Hot Water (DHW)
The total system for CH and DHW-production consists of:
• The boiler;
• Central heating and vent piping;
• Radiators; baseboard; in floor heating and/or hydronic
air handlers
• Hot water taps.
Main parts
The
boiler consists of the following main parts:
Figure 1.1
CH Heat exchanger
The heat exchanger located in the middle of the boiler makes sure that the heat that becomes available during
the gas burning process is transferred to the CH circuit.
DHW heat exchanger (only Cxxx types)
The heat exchanger located in the back of the boiler makes sure that the heat that becomes available during
the gas burning process is transferred to the DHW circuit.
Fan
The air necessary for gas burning is propelled by a fan. To save electrical energy the
boiler has
been equipped with a high efficiency fan.
Burner
The fan brings forward the gas / air blend necessary for the burning process. The ignition electrode ignites
the blend to drive the burning process.
Gas valve
The gas valve makes sure the exact amount of gas necessary for burning is supplied.
3-way valve and circulation pump
The heat generated by the burning process is used within the CH or DHW circuit. The 3-way valve makes sure
the correct circuit is driven depending on the demand. The pump makes sure the correct amount of water is
delivered through the cold water intake.
Burner control
The burner control drives the general steering and safety system of the boiler
