Minimum Clearance; Flue Gas Temperature Sensor - Bosch Condens 7000 WP Installation And Maintenance Instructions Manual

2.11

Minimum clearance

With a horizontal flue outlet, make sure the electronic components
inside the boiler at the top remain accessible when placing an elbow
directly on the flue outlet adapter.
▶ After fitting the flue bend, check whether the upper panel of the
appliance is easy to remove (§ 7.2, p. 18).
▶ There must be a clearance of at least 100 mm directly above the flue
bend at the boiler.

Table 3 Clearance A and B depending on flue outlet
Calculate the minimum clearance above the boiler.
▶ Add dimension B from Table 3 to the height of the top of the boiler.
▶ With a horizontal flue outlet:
– Add 52 mm to dimension B for every meter of horizontal flue
outlet.
– In this case also take the diameter of the collar into consideration.
▶ With a vertical flue outlet:
– Maintain a clearance of at least 100 mm above the boiler to allow
the electronic components to be accessed and worked on.
Minimum space required for the boiler.
▶ Provide an unobstructed space of at least 100 cm for the boiler to
allow maintenance and other work to be carried out.
Minimum space required next to the boiler.
▶ Maintain an area of at least 5 mm on the either side of the boiler.

Flue gas temperature sensor

The boiler is manufactured with a flue outlet sensor as standard ( Fig.
1, p. 6).
The flue gas temperature sensor protects the boiler and flue system from
high flue gas temperatures by reducing the boiler load (downward
modulation).
