7.10 Checking the leak-tightness of the flue gas
system and for flue gas recirculation
1. Check that the flue gas system is intact, in accordance
with British Gas TB 200.
2. If the flue gas system is longer than 2 m, we urgently
recommend that you test the system for flue gas recir-
culation as described below.
3. Use the air analysis point (1) to check for flue gas recir-
culation.
4. Use the flue gas measuring instrument.
5. If you discover CO or CO2 in the fresh air, search for a
leak in the flue gas system or for the flue gas recircula-
tion.
6. Eliminate the damage.
7. Repeat the above-mentioned test to determine if the
fresh air contains CO or CO2.
8. If you cannot eliminate the damage, you must not start
up the boiler.
7.11 Checking function and leak-tightness
Before you hand the product over to the operator:
▶ Check the gas line, the flue gas installation, the heating
installation and the hot water pipes for leaks.
▶ Check that the air/flue pipe and condensate drain pipe-
work have been installed correctly.
▶ Check that the front casing has been installed correctly.
7.12 Checking the heating mode
1. Activate the heating mode on the user interface.
2. Turn all thermostatic radiator valves on the radiators
until they are fully open.
3. Allow the product to operate for at least 15 minutes.

8 Adapting the unit to the heating
installation
You can reset/change the system parameters (section "Us-
ing diagnostics codes").
Overview of diagnostics codes (→ Page 25)
8.1 Burner anti-cycling time
To prevent frequent switching on and off of the burner and
thus prevent energy losses, an electronic restart lockout
is activated for a specific period each time the burner is
switched off. The burner anti-cycling time is only active for
the heating mode. Hot water handling mode during a burner
anti-cycling time does not affect the time function element.
8.1.1 Setting the burner anti-cycling time
▶ Set the diagnostics code. (→ Page 15)
Overview of diagnostics codes (→ Page 25)
8.1.2 Resetting the remaining burner anti-cycling
time
▶ Press and hold the fault clearance key for more than
three seconds.

is shown in the display.
9 Handing the product over to the
operator
▶ When you have finished the installation, attach the sticker
supplied (in the operator's language) to the product
cover.
▶ Explain to the operator how the safety devices work and
where they are located.
▶ Inform the operator how to handle the product.
▶ In particular, draw attention to the safety information
which the operator must follow.
▶ Inform the operator of the necessity to have the product
maintained on a regular basis.
▶ Instruct the operator about measures taken to ensure the
supply of combustion air and flue gas pipe.
10 Inspection and maintenance
10.1 Observing inspection and maintenance
intervals
▶ Adhere to the minimum inspection and maintenance in-

10.2 Procuring spare parts
The original components of the product were also certified
as part of the declaration of conformity. If you do not use
certified Glow-worm original spare parts for maintenance
or repair work, this voids the conformity of the product. We
therefore strongly recommend that you install Glow-worm
original spare parts. Information about available Glow-worm
original spare parts is available by contacting the contact
address provided on the reverse of this document.
▶ If you require spare parts for maintenance or repair work,
use only Glow-worm original spare parts.
