1 General information
Installation of a gas-fired heating system must be
performed in accordance with the applicable regula-
tions and guidelines. It is therefore the duty of the in-
staller to be fully familiar with all regulations.
Installation, start-up and maintenance must be per-
formed with utmost care.
The burner must not be operated in rooms with high
levels of air humidity (laundry rooms), dust or corro-
sive vapours. The boiler room must be ventilated ac-
cordingly with ventilation air.
Giersch MG Series gas burners are suitable for
combustion of natural gas in accordance with
DIN EN 437 and are in compliance with the
DIN EN 676 European standard.
2 Checking scope of supply and
electrical ratings
Before installing the gas burner, please check the
scope of delivery.
Scope of delivery:
burner housing, gas jacket with burner pipe, mount-
ing kit, documentation and gas train.
Gas installation and commissioning are subject to
the applicable national regulations, e.g. in Germany
the Technical Regulations of the DVGW (DVGW-TR-
GI).
The following must be observed for Switzerland:
SVGW Gas Provisions G1, G3: Gas installation
EKAS Form.
1942: Liquefied gas regulation, Part 2 Regulations
of cantonal authorities (e. g. fire department regula-
tions).
The gas pipe must be designed to conform to the
flow rate and the available gas flow pressure and
routed with the lowest pressure loss over the short-
est distance to the burner.
The loss of gas pressure via the gas train and the
burner as well as the resistance on the fuel gas side
of the heat generator must be less than the connec-
tion flow pressure.
Caution !
Observe sequence and through-flow direction
of valves and fittings.
