Minimum Clearance From Walls; Flue Gas Temperature Sensor - Bosch GC7000WP 50 23 Installation And Maintenance Instructions Manual

2.13

Minimum clearance from walls

With a horizontal flue gas connection, 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 top cover of the
appliance is easy to remove ( § 7.2, p. 18).
▶ There must be a clearance of at least 100 mm directly above the bend
at the boiler.

Table 4 Clearance A and B depending on flue outlet
Determine the minimum clearance above the boiler.
▶ Add dimension B from Table 4 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.
Distance from walls at sides.
▶ Maintain a clearance of at least 5 mm on the weather 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 setting back the boiler load
(downward modulation).
