Notes regarding the flue pipe
connection and flue gas monitoring
5.1.1 Flue gas connection
Observe the following during the installation of the flue
gas connection:
–
The flue pipe cross-section must comply with all
current regulations.
–
Select the shortest possible flue pipe run.
–
Route flue pipes inclined to the chimney.
–
Never fit thermostatically controlled flue gas dampers
into flue pipes.
5.1.2 Flue gas monitor
Check, whether because of the building utilisation or
regional/national regulations, flue gas monitoring
equipment is required.
!
If necessary, install such equipment in accordance
with current regulations.
Type B
11
(excl. flue gas monitoring)
Only install boilers without flue gas monitoring
equipment in rooms, which are not part of the living
accommodation of the building and which are provided
with ventilation in accordance with current regulations,
e.g. boiler rooms.
Type B
11BS
(incl. flue gas monitoring)
Flue gas monitoring equipment may be required in
accordance with regional or national regulations or laws,
e.g. when boilers are operated in living accommodation,
similar utility rooms or in an attic installation.
The flue gas monitor interrupts the gas supply, should
flue gas enter the boiler room. The burner will then be
switched OFF.
WARNING!
RISK TO LIFE
through poisoning.
Unauthorised access to the flue gas
monitoring can cause a risk to life through
escaping flue gas.
!
Never repair the flue gas monitoring
system.
!
Only use original spare parts as
replacements.
!
After the replacement, fit the flue gas
temperature sensor into its appropriate
position.
WARNING!
RISK TO LIFE
through poisoning.
Insufficient ventilation can lead to
dangerous flue gas leaks.
!
Never close or obstruct air ducts and
vent apertures or reduce their size.
!
The boiler must not be operated,
unless you immediately remedy the
fault.
!
Inform the system user in writing of the
fault and its associated dangers.
