ASSEMBLY
6.4.1
Fitting the flange with tube
Fig. 22: Fitting the flange with tube (shown for standard version)
Work to be performed
1
Measure the fitting location and mark the assembly location, ensure sufficient clearance
to fit and remove the sender/receiver unit (
see “Sender/receiver unit space require-
).
2
Remove thermal insulation (when fitted).
3
Cut suitable openings in the duct wall; bore large enough holes in brick or concrete
stacks (flange tube diameter).
4
Insert the flange with tube in the opening slanting slightly downwards (1 to 3°) so that
the “Top” marking points upwards and any condensate that may collect in the duct can
drain off.
5
Weld the flange with tube on using an anchor plate for brick or concrete stacks, insert
junction plates for thin-walled ducts.
6
Close off the flange opening with a blind flange after fitting (
) to prevent gas escaping.

Flange with tube
●
Dimension a must be large enough so that a weather hood housing can be fitted
easily when necessary (approx. 40 mm).
●
Dimension b must be as large as possible under consideration of dimension a.
NOTE:
The tube length must suit the planned sender/receiver unit depending on the relation
between gas temperature and nominal length (
see “Flange with tube”, page 31
▸
Do not shorten tubes.
NOTE:
▸
Do not let separated pieces fall into the duct.
