6. ASSEMBLING INSTRUCTIONS
6.6 Gas Line Connections
Before connecting to mains gas line please, check the following points.
The gas type which the boiler will be operated must conform the boiler is equipped with.
Gas pipes should be clean.
Please, be sure to use a 3/4" gas filter at the gas inlet. Check all the pipework and connections against leaks.
Do not use gas pipes for electrical grounding purposes.
6.7 Flue Assembling
Original flue terminal and assembly kit must be used, any modification on the flue and the parts is not permitted.
The flue system fitted to the combi boiler must be inclined towards the appliance at an angle of 3o to prevent condensate
dripping from flue terminal.
The combi boiler must be installed so that the flue terminal exposed to the external air.
If the material of the wall is not suitable to use with the flue terminal then the flue terminal must be insulated minumum
200 mm in thickness.
Do not pass the flue terminal through the ceiling, if it is a must, then the flue terminal must be insulated minumum
200 mm in thickness.
The spacing between flue duct and wall hole should not be fiiled with the material such as concrete, gypsum etc. which
prevents the easy mintenance work.
The flue terminal must be extended completely out of the wall, check the terminal is not clogged.
Be sure that the position of the flue terminal allows air and gas passage at all times.
The distance between the top of the flue and the next floor must not be less than 50 mm (as shown in the below figure).
If flue extension is needed, be sure all the extension points are sealed and thre is no gas leak in the room.
The combi boiler must be installed together with the flue terminal and the flue must be extended out of the wall. (as
shown in the below figure).
Use of the combi boiler w/o hermetic flue terminal is prohibited.
The flue terminal could be installed in accordance with the installation requirements.
See the horizontal flue terminal lengths with or without Flow Limiting Part (FLP) in the above table.
Note:
Each 90
0
bend/extension equals 1 meter of lflue loss. It means for every bend or extension the maximum
flue length should be reduced 1 meter.
