External Sensor Set-Up; Completion; Operational Checks - Ariston Benchmark System A 24 RFF Installation And Servicing Instructions

14.7 External sensor and ambient sensor set-up (where fitted)
N.B.
To ensure that these parameters are set correctly, consult the
"thermo-regulation help" document enclosed with the
documentation folder.

14.8 Completion

For the Republic of Ireland it is necessary to complete a
"Declaration of Conformity" to indicate compliance to I.S.813. An
example of this is given in the current edition of I.S.813. In
addition it is necessary to complete the
Commissioning Checklist in Section 24 of this manual (Page 60).

14.9 Operational checks

1. The system must be visually checked for soundness;
2. Fill the condensate trap with water, by pouring
litre of water into the exhaust flue connector (see
Fig. 39). N.B. In the event of a prolonged period of
system shutdown, the condensate trap should be
filled before any renewed use. A shortage of water
in the trap could possibly lead to a temporary
leakage of fumes into the air, until it refills itself;
3. Ensure that the flue is fitted correctly;
4. Allow the central heating system to warm up and adjust
the central heating temperature control knob 31 (Fig.1),
check the burner modulates between the high and low
settings;
5. Range rate the thermal power for central heating as
detailed in Section 14.5. To adjust the maximum heating
power it is necessary to follow the steps in Section 14.5
Menu 4. and adjust in relation to the chart on Page 35
(Fig. 42);
6. Check the gas rate;
7. Record the finding in the Benchmark Commissioning
Checklist (Page 59);
8. Run the domestic hot water and adjust to the correct
water flow rate, adjust the domestic hot water
temperature control knob 30 (Fig.1) to ensure the burner
modulates between the high and low settings;
9. Balance the central heating system until all return
temperatures are correct and equal;
10. Turn the boiler off by pressing the On/Off button 27
(Fig.1) to OFF, disconnect the gas pressure gauge,
retighten the screw and relight the boiler;
11. Re-examine the central heating, domestic hot water and
old water supplies for soundness;
12. If external controls have been disconnected, reconnect
and test;
13. Refit the boiler casing.
