4.5 

Flue gas connection, chimney 

and condensate pipeline

NOTICE

The condensate from the exhaust gas sys-

tem must not be discharged through the boil-

er. The condensate must be discharged from 

the exhaust pipe before the boiler through a 

siphon.

Due to water vapour content of the flue gases with low 

temperature and the resulting further condensation in the 

flue, heat output boilers cannot be connected to standard 

house flues.

The applicable local authority regulations and the special 

regulations in the DVGW-(TRGI), ÖVGW and SVGW di

-

rectives are to be complied with for flue gas removal.

In  accordance  with  the  VKF-guidelines  (edition  1993, 

number 3.4.8) for Switzerland a flue gas temperature lim

-

iting device according to the above mentioned directive 

must be installed in the flue gas pipeline.

There are two possibilities of flue gas removal with heat 

output gas boilers:

a)  The use of specially approved flue gas pipelines,

b)  Use of damp-insensitive flues, approved for flue gas 

temperatures  starting  from  40  °C,  connected  to  the 

heat output boiler in the boiler installation room via ap-

proved flue gas pipelines.

In both cases the cross sections and maximum lengths 

based on the values for flue gas flow rate, flue gas tem

-

perature and flow pressure available at the flue gas con

-

nector are to be calculated according to the table on 

chap ter 3.1 (DIN 4705).

The calculation is normally made by means of graphs 

or tables provided by the manufacturer of the moisture-

resistant flue of the special flue gas pipeline. Often this 

manufacturer performs the calculation using a computer 

program specially created for the model in question.

In  any  case,  we  recommend  a  discussion  with  the  re

-

sponsible local chimney sweeping supervisor prior to the 

planning  and  execution  of  the  flue  gas  extraction  with 

heat output gas boilers.

4.5.1  Waste gas pipelines in compliance 

with building construction law

The flue gases from the Hoval TopGas

®

 (35,45,60) can 

be  removed  via  a  gas-tight,  temperature  and  corrosion 

resistant  flue  gas  pipeline.  Only  flue  gas  systems  ap

-

proved and tested by the relevant region or province are 

to be connected to the Hoval TopGas

®

 (35,45,60) (the ad

-

missions of individual federal states should be complied 

with  in Austria). The  suppliers  of  the  flue  gas  pipelines 

supply suitable boiler connectors for the transition from 

the boiler to the flue gas pipeline. The flue gas connector 

on the Hoval TopGas

®

 (35,45,60) has a concentric flue 

gas connection ø 80/125 mm.

We recommend installation of the connector 

piece  (boiler  flue  gas  connector  vertical  flue 

gas pipeline) in the same diameter as the flue 

gas connector on the TopGas

®

.

The planning and installation instructions of the manufac-

turer together with the building construction regulations 

are to be observed in the planning and execution of the 

flue gas pipeline. A timely discussion with the responsible 

local chimney sweeping supervisor is recommended.

Your Hoval agent can supply a suitable and approved flue 

gas system for your TopGas

®

.

Please take note of the technical information supplied 

with your flue gas pipeline.

4.5.2  Project planning information for the TopGas

®

• 

All  applicable  regional,  national  and  state  regulations 

are to be observed with respect to the flue gas extrac

-

tion system.

• 

All air inlet/flue gas pipelines must have a measuring 

orifice (already incorporated in the moduel kits). These 

are to be positioned where they can be easily accessed 

for measuring purposes. 

•  The concentric length elements cannot simply be short-

ened. Length adjustment pieces or cut to length pieces 

are to be used for adjusting to the required lengths.

• 

Single flue gas pipes can be shortened to the neces

-

sary length but must however be cleanly deburred be-

fore the assembly, to prevent damage to the seal in the 

counter-piece.

• 

When installing the pipes in a shaft, spacer elements 

must be mounted every 2 m. For the vertical supporting 

of the chimney pipeline, the very bottom element must 

be permanently fixed (mounting rail or pipe clip).

•  Horizontal connections must have a gradient of at least 

5  cm  per  running  metre  in  the  direction  of  the  boiler, 

to  permit  unobstructed  flow  of  the  condensate  to  the 

boiler. The complete flue gas system must be installed 

to prevent the accumulation of condensate.
