Commissioning

7.1

Initial commissioning - information for service companies

7.1.1 Initial commissioning of the burner

Before commissioning, check the following:

– Gas distribution does not show any visible deficiencies (should correspond to 

TPG 704 01), setting the main regulating element on the main gas line to the correct 
gas pressure value (for long and complex multi-unit> 2 kPa or> 3 kPa for propane- 
butane distribution) whether the location of the units corresponds to this manual (see 
Chap. 4) and the fuel used corresponds to the fuel setting of the unit 

– Local conditions of the electrical power supply or fusing (are the specifications on 

the unit identification plate taken into consideration?)

– Electrical connections correspond to the wiring diagrams (see Fig. 5-4 to Fig. 5-5)

HAZARDOUS VOLTAGE!

The Multi

MAXX

 HG unit heater may only be electrically installed by skilled 

electricians trained for this task who observe all the valid regulations.

DANGER OF BURNING!

The heat exchanger and the flue-gas venting reach very high temperatures 
in operation.

RISK OF ACCIDENTS DUE TO GAS EXPLOSION!

Before all work at the gas unit heaters, cut off the gas supply with the shut off valve. 
Block the gas main, since it otherwise can lead to a gas flow which can cause an 
explosion, fire etc..
The gas installation of the unit heaters may only be carried out by trained skilled 
workers observing the valid regulations.

NOTE!

The initial commissioning may only be carried out by specialists who are expert 
in the prevailing standards and regulations and are included in the list of authorized 
service companies.

NOTE!

For commissioning of the Multi

MAXX

 HG equipment, observe the valid security 

regulations and standards of the respective countries and the generally recognized 
rules of the technology.

NOTE!

Before commissioning, a required inspection must be conducted according to all the 
prevailing standards. 
Observe the provisions of this Operation Manual at all times during commissioning.
The operator is obligated to conduct regular inspections and maintenance of the 
electrical and gas connections according to all the prevailing standards (see str. 55). 
The first start-up of the Multi

MAXX

 HG unit must be carried out by a professional, 

authorized company .

NOTE!

The torch power connector the burner is sealed with the FläktGroup logo tape. 
Before starting up for the first time, make sure that the tape is not damaged and that 
the burner has not been properly lowered.
