The heater must only be connected by an authorized organization.
Before connecting, check that the type and pressure of the gas corre-
spond to the data on the data label (on the rear panel of the heater).
The gas hose is subject to regular inspections and inspections as gas
distribution (TPG 704 01). Hoses must be protected against mechani-
cal stress and aggressive substances. The hose must not be subjected
to tension.
Electrical installation
The MONZUN heaters are connected to the terminal block by a pow-
er supply with a stop switch/circuit breaker. The power input is deci-
sive for supply sizing. The MONZUN heaters must be connected to
the TN-S system in accordance with the applicable standards. The
power supply must have the required protection according to the
relevant standard. According to EN 61140, MONZUN heaters are class
I electrical appliances and are equipped with a protective conduc-
tor connection terminal. This terminal must be connected acc. to the
above standard
Notice: After removal of the side door at the burner chamber, according to EN 60 947-1, the protection of the device is IP 00
(there is a risk of electric shock)
FLUE EXHAUST AND COMBUSTION AIR SUPPLY
Flue gas discharge is forced, through a flue outside the building
The appliance is classified in categories B23, C13, C33 and C63 ac-
cording to the method of exhaust gas – see EN 1020
The design and installation of the flue pipe must comply with the
relevant standard
The fan of the premix burner of MONZUN heaters, together with
the gas fitting and the venturi tube, ensures a constant mixing ra-
tio of fuel and air in the entire performance range
If the pressure losses in the flue gas exhaust system and the com-
bustion air supply are too high, the transported amount of the
mixture will decrease and the burner performance will decrease
In case of blockage, the heater will be shut down
The maximum temperature of the flue gas at the outlet of the heat-
er does not exceed 200 °C
The hot air heater is equipped with two sockets (female) – one for
connecting the flue pipe and the other for air intake
Flue gas discharge can be realized by:
– flue gas duct terminated by end cap
– coaxial chimney, which simultaneously removes flue gas and air
intake for combustion
Combustion air supply can be realized by:
– from the area where the heater is located
– from outside using piping for suction
– coaxial chimney, which simultaneously removes flue gas and air
intake for combustion
