ASSEMBLY AND INSTALLATION 3
3.2.2 Work to be performed
▸ Measure the fitting location and mark the assembly location.
Leave enough clearance around the flange with tube to fit the sender/receiver unit.
Fig. 10: Clearance for sender/receiver unit (dimensions in mm)
▸ Remove insulation (when fitted).
▸ Cut suitable openings in the duct wall; bore large enough holes in brick or concrete stacks (flange
tube diameter (see “Flange with tube”, page 65))
.
▸ Insert the flange with tube in the opening slanting slightly downwards (1 to 3°, see
“Fitting the flange with tube”, page 22) so that the “Top” marking points upwards and
any condensate that may collect in the duct can drain off.
▸ Weld the flange with tube on using an anchor plate for brick or concrete stacks, insert
junction plates for thin-walled ducts (see “Fitting the flange with tube”, page 22).
▸ Close off the flange opening after fitting to prevent gas escaping.
3.2.3 Fitting the optional external purge air unit.
Consider the following points when selecting the assembly location:
▸ Install the purge air unit at a location with clean air whenever possible. The air intake
temperature must correspond to specifications in the Technical data (see “Technical
data”, page 62). In unfavorable conditions, lay an air intake hose or pipe to a location
with better conditions.
▸ The fitting location must be easily accessible and meet all safety regulations.
▸ Install the purge air unit only as far as necessary below the flange with tube so that the
purge air hoses can be laid downwards (avoids water collecting).
▸ Provide sufficient clearance to exchange the filter element.
