Important information
VG 2.210 V burners are designed for the low-pollutant combustion of natural gas and propane gas. The design and function of the burners meet standard EN 676. They are suitable for use with all heat generators complying with standard EN 303 or for use by hot air generators complying with standard DIN 4794 or DIN 30697 within their respective performance range. Any other type of application requires the approval of ELCO. Installation, start-up and maintenance must only be carried out by authorised specialists and all applicable guidelines and regulations must be complied with.
Burner description
VG 2.210 V burners are two-stage fully automatic monoblock devices. The special design of the combustion head enables combustion with low levels of nitrogen oxide and increased output. Class 3 type-approval in accordance with EN676 certifies that the lowest emission values have been achieved and means that the national environmental regulations have been met AT: KFA 1995, FAV 1997 CH: LRV 2005 DE: 1.BImSChV Emissions values may differ, depending on combustion chamber dimensions, combustion chamber load and the firing system (three-pass boilers, boilers with reverse firing). For specifying warranty values, the conditions for the measuring equipment, tolerances and humidity must be observed.
Packaging
The burner packaging also contains: 1 Gas connection flange 1 Compact gas train with gas filter 1 Burner flange
with insulation
Page
1 Bag containing mounting parts 1 Bag containing Technical
Documentation
The following standards should be observed in order to ensure safe, environmentally sound and energy­efficient operation:
EN 226
Connection of fuel oil and forced­draught gas burners to a heat generator
EN 60335-1, -2-102
Specification for safety of household and similar electrical appliances, particular requirements for gas burning appliances
Gas lines
When installing the gas lines and trains, the general directives and guidelines, as well as the following national regulations, must be observed: CH: - G1 instruction text from SSIGE
- EKAS form no. 1942, liquefied gas directive, part 2
- Cantonal authority guidelines
(e.g. directives for the pilot valve)
DE: - DVGW-TVR/TRGI
Installation location
The burner must not be used in rooms with aggressive vapours (e.g. hair spray, tetrachloroethylene, carbon tetrachloride), high levels of dust or high air humidity (e.g. laundry rooms). If no connection to an air exhaust system is provided for the air supply, there must be a supply air inlet measuring: DE: up to 50 kW: 150 cm
per additional kW: : + 2.0 cm

CH: QF [kW] x 6= ...cm2; but at least
200 cm2. Variations may arise as a result of local regulations.
09/2013 - Art. Nr. 4200 1053 2900A2
We accept no responsibility for damage arising from:
- inappropriate use.
- incorrect installation and/or repair on the part of the buyer or any third party, including the fitting of non-original parts.
Final delivery and instructions for use
The firing system fitter must supply the operator of the system with operating and maintenance instructions on or before final delivery. These instructions should be displayed in a prominent location at the point of installation of the heat generator, They should include the address and telephone number of the nearest customer service centre.
Notes for the operator
The system should be inspected by a specialist at least once a year. Depending on the type of installation, shorter maintenance intervals may be necessary! It is advisable to take out a maintenance contract to guarantee regular servicing.

Operation
Description of the function Safety functions
Description of the function
A pre-ventilation time of 24 seconds begins when first powering up, after a power cut or a lockout, after the gas supply has been cut or after a shutdown for 24 hours.
During the pre-ventilation time
- the air pressure is monitored
- a check is made for the presence of any abnormal flame signals.
At the end of the pre-ventilation time
- the ignition is switched on
- the main and safety solenoid valves are opened.
- burner start-up
Monitoring
The flame is monitored by an ionisation probe. The probe is fitted with insulation to the gas head and is routed through the turbulator into the flame zone. The probe must not have any electrical contact with earthed parts. The burner switches to malfunction if a short circuit occurs between the probe and the burner earth. During burner operation, an ionised zone is produced in the gas flame through which a rectified current flows from the probe to the burner tip. The ionisation current must be at least 8µA.
Safety functions
- If no flame is produced when the burner is started (gas release), the burner is switched off at the end of the safety time which lasts no more than 3 seconds and the gas valve closes.
- If the flame is lost during operation, the gas supply is cut within a second. A new start-up sequence is activated. If the burner starts, the operating cycle starts running. Otherwise a lockout occurs.
- If there is an air failure during pre­ventilation or operation, a lockout occurs.
- If there is a gas failure, the burner either stops or will not start. As soon as sufficient gas pressure is available again, the burner restarts.
During the regulator shutdown
- The control thermostat interrupts the heat request.
- The gas valves close
- The flame goes out
- The blower motor stops
- The burner is ready for operation

CH note
In accordance with SSIGE instructions, it is compulsory to install a gas safety valve (mark 1) in the pipe
DE Note
In compliance with the reference layout applicable to boiler rooms, sites with gas furnaces must be fitted with a thermal gas shut-off valve (1).

Operation
TCG 8xx control unit
The TCG 8xx control and safety unit controls and monitors the forced draught burner. The microprocessor-controlled program sequence ensures maximum stability of time periods, regardless of fluctuations in the power supply voltage or the ambient temperature. The automatic combustion control unit is designed to cope with brownouts. Whenever the supply voltage drops below its rated minimum level (< 185V), the control unit shuts down - even in the absence of a malfunction signal. The control unit switches itself back on again once the voltage has returned to normal levels (> 195V).

Locking and unlocking
The control unit can be locked (switched to malfunction mode) by pressing the unlocking button and unlocked (fault deleted), provided the unit is connected to the mains power supply.
Always switch off the power supply before installing or
removing the control unit. Do not attempt to open or carry out repairs on the control unit.

- the position of the air flap at minimum pressure
- the position of the air flap at maximum pressure
• menu for setting the servomotor
• menu for storing the servomotor setting points in the display
The parameters for the control unit are set using the display and 5 keys. Operating values are shown in real time on the display.
Pressing the keys gives access to 9 menus:
• menu for setting industrial applications*
• menu for manual control*
• fault diagnosis menu
• operating statistics menu
• menu for setting/ adjusting the standard configurations*
• Parameter mode menu*
• Menu for adjusting screen contrast and brightness settings
* In these menus, it is
possible to adjust the control unit's standard configurations. These are pre-set in the factory. No modifications may be carried out on-site without prior consultation with ELCO. The access code and the setting setpoints for these menus are available on request.
