2. GENERAL SPECIFICATION
The Marco 24-CPM and 30-CPM are a range
boilers that use premix technology and achieve a grade A rating
of
high efficiency condensing combination
in
SAP 2009. They are
designed to provide both Domestic Hot Water (DHW) and Central Heating (CH), although
the CH does not operate while the DHW is being used. The boilers are designed to be
wall hung and are room sealed, that is they obtain the air for combustion from outside
of

Natural Gas.
Both horizontal and vertical flues can be used and various elbows can be used to
of
accommodate a more complex route between the boiler and the outside
the dwelling.
The main printed circuit board provides all the functionality and safety features for
the boiler.
The board operates the gas valve, fan, pump,3-way valve and flame supervision.
The safety systems built into your appliance provide entire safety for you and your
appliance. The safety systems are:
> Flue Gas Over-heat Safety System (105 °C)
> Flame Failure Supervision
> Boiler Over-heat Safety thermostat 2 levels: 95 °C and 105 °C)
> DHW (Domestic Hot Water) Over-heat thermostat
> CH Over Pressure Protection (3 bar)
> CH Low Water Pressure Protection (0,8 bar)
> High Voltage Protection System (260 VAC)
> Low Voltage Protection System (160 VAC)
