Overview
Overview
General information
Installation of a gas-fired heating system must be performed in accordance with the applicable regulations
and guidelines. It is therefore the duty of the installer to be familiar with all applicable regulations and re-
quirements. Installation, start-up and maintenance must be performed with utmost care.
The burner must not be operated in rooms with high levels of air humidity (laundry rooms), dust or corrosive
vapours. The boiler room must be ventilated accordingly with ventilation air. The ENERTECH GG10-LN se-
ries of gas burners are suitable for burning natural gas or liquefied petroleum
gas in accordance with DIN EN 437 and comply with the European Standard DIN EN 676.
Scope of delivery and connection data
Before installing the ENERTECH gas burner, please check the scope of delivery.
Scope of delivery:
Burner, sliding flange and gasket, 4 retaining screws, separate operating instructions,
technical information, one 7-pin connector, gas ramp and gasket.
Gas installation and commissioning are subject to the applicable national regulations, e.g. in Germany the
Technical Regulations of the DVGW (DVGW-TRGI).
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
regulations).
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 shortest distance to the burner.
The loss of gas pressure via the gas ramp and the burner, and the resistance on the fuel gas side of the
heat generator must be less than the connection flow pressure.
Caution !
Observe the through-flow direction of the gas ramp.
Operating instructions
The operating instructions together with this technical information leaflet must be displayed in a clearly vis-
ible position in the boiler room. It is essential to enter the address of the nearest customer service centre
in the operating instructions.
Instruction of operating personnel
Faults are often caused by operator error. The operating personnel must be properly instructed in how the
burner works. In the event of recurring faults, Customer Service should be notified.
Maintenance and customer service
The complete system should be checked once a year for correct functioning and leaks by a representative
of the manufacturer or other suitably qualified person.
We accept no liability for consequential damage in cases of incorrect installation or repair, the fitting of non-
genuine parts or where the equipment has been used for purposes for which it was not intended.

Installation
Installation
Mounting the flange and burner
1. Mount the flange base and gasket onto the boiler:
- Observe "top" mounting position,
- Tighten M8 screws including U-washer,
- Place the flange top section (half shell) onto the burner tube.
During the assembly procedure, ensure that the 0° display on the flange top aligns with the
"top" display on the flange base.
2. Installing the burner:
- To mount the burner, engage the burner housing in the retaining lugs by rotating it clockwise.
- Tighten the clamping screw. Make sure that the conical nipple is inserted in the lower part of the
flange correctly.
Mounting the gas ramp !
• Remove plastic protective plug.
• Mount the screw connections with enclosed seals.
• Observe the installation position.
• Check connecting point of gas ramp with non-corro-
sive foaming agent for leaks and vent the gas pipe.
• When venting, use a hose to discharge the gas
safely to the atmosphere.
The gas supply line and gas assembly must not exert tensile, compression or torsional
forces on the burner, since this can otherwise adversely affect operational safety.
In Germany, observe DVGW-TRGI 1986/96 Section 7, TRF 1988, DIN 4756 and
local regulations
