corrosion damage and malfunctions on fuel-burning installations. If the
combustion air has to be drawn via an already existing chimney, this flue
gas tract should be inspected and if necessary cleaned. Should structural
deficiencies (e.g. old, broken chimney structures) oppose its use as a
combustion air supply duct, suitable measures such as shake-out of the
fireplace should be taken. It must be ensured that there is no
contamination of the combustion air with foreign matter.
If an appropriate clean up of the existing flue gas tract is not possible, the
heat generator can be operated on a concentric flue gas pipe independent
of ventilation. . The concentric flue gas pipe must run straight in the shaft.
Lightning protection
Danger of electric shock
Danger to life due to lightning strike.
The chimney head cover must be integrated in any existing
lightning protection system and house-side potential equalisation.
This work should be carried out by an approved company
specializing in lightning protection and electrical work.
Shaft requirements
Inside buildings, exhaust gas system should be laid in suitable ventilated
shafts. The shafts must be made of non-combustible, dimensionally stable
materials.
Fire resistance duration of the shaft: 90 min.
Fire resistance duration of the shaft in case of buildings of lower building
height: 30 min.
6.4.6 Mounting the flue gas system
Warning
Danger of injury by not wearing working gloves.
Wearing working gloves is recommended during assembly work,
particularly while cutting the pipes.
Mounting with gradient
The flue pipe must be routed at a gradient to the Paramount so that the
condensation from the flue pipe can drain from the flue pipe to the central
condensation collector of the Paramount.
The min. gradients are:
horizontal flue pipe: min. 3° (min. 5.5 cm per metre)
external wall duct: min. 1° (min. 2.0 cm per metre)
Shortening of the pipes
All simple and concentric pipes may be shortened. After cutting, the ends
of the pipes have to be thoroughly de-burred. When a concentric pipe is
shortened, a piece of pipe at least 6 cm long must be cut off the outer
pipe. The spring washer for centring the inner pipe becomes obsolete.
1. The pipes and formed pieces have to be fitted together up to the
connector basis. Only the original profile seals of the building kit or the
original spare seals may be used between the individual elements.
Before assembly, the seals must be treated with the silicone paste
which is part of the scope of delivery. When routing the pipes care
must be taken that the pipes are installed in line and without tension.
In this way leaking of the seals is prevented.
