9.13.2 Checking the air/flue pipe/flue gas
recirculation
1. Check whether the front casing (vacuum chamber) has
been closed tightly.
2. Start up the product in chimney sweep mode.

Section 8.9)
3. Check the flue gas installation is intact in accordance
with the latest gas safe technical bulletin and informa-
tion supplied in the installation instructions.
4. For extended flue gas installations check for flue gas
recirculation using the air analysis point.
5. Use a flue gas analyser.
6. If you discover unusual levels of either CO or CO
2
or
O
2
in the supply air, search for the leak in the flue sys-
tem or for signs of flue gas recirculation.
7. Eliminate the damage properly.
8. Check again whether the supply air contains any un-
usual levels of either CO or CO
2
or O
2
.
9. If you cannot eliminate the damage, do not start up the
product.
10. Seal the test openings again using the sealing caps.
9.13.3 Checking the gas connection pressure/gas
flow pressure
1. Ensure that the gas inlet working pressure can be ob-
tained with all other gas appliances in the property
working.
2. Remove the front casing. (

Turning anti-clockwise: 2
6. Connect a manometer to the test nipple (2) for the gas
valve assembly.

Working materials: Digital pressure gauge
7. Hinge the electronics box upwards.
8. Ensure that the heat is dissipated in the heating or
domestic hot water system.
9. Open the gas stopcock.
10. Start up the product at maximum power in chimney
sweep mode.
11. Wait until status displays S.004 , S.014 and S.024 have
gone out.
12. Measure the gas connection pressure/gas flow pres-
sure against the atmospheric pressure.
13. Monitor the measured value. If the measured value
remains stable within a small tolerance, note down the
measured value.
14. Temporarily decommission the product.

15. Stop the heat demand in the heating and domestic hot
water system.
16. Allow the boiler to cool down allowing pump overrun to
operate for a minimum of two minutes.
17. With the boiler operating at full load check that the gas
inlet working pressure at the reference test point com-
plies with the requirements.
18. Remove the manometer.
19. Tighten the screw plug for the test nipple on the gas
valve assembly. Tightening torque, see appendix.
20. If the test nipple on the gas isolation valve has been
used, tighten the screw plug for the test nipple. Tight-
ening torque, see appendix.

Working materials: 3 mm hex key
21. Open the gas stopcock.
22. Check all test nipples in the gas route for gas tightness.
