5. COMMISSIONING
It is essential that all new pipework installations are purged and tested for soundness using a suitable leak detection
fluid prior to attempting to ignite any appliance. This work should be carried out in accordance with National or Local
Regulations.
N.B. DO NOT TEST FOR SOUNDNESS BY USE OF NAKED FLAMES .
5.1 Ignition .
5.1.1 Turn on the gas supply to the appliance.
5.1.2 Switch on the electrical supply to the appliance.
5.1.3 If the appliance has a thermostat fitted in the electrical supply circuit, ensure that it is set high enough to demand
heat. Ultra HI/LO (e.g. Ultra 7/3.5): ensure that the second thermostat (T2 - see Fig. 4) is set high enough to call for
heat also.
5.1.4 After a waiting time of 1 second, the solenoid valves and the spark ignition electrode will be energised
simultaneously.
5.1.5 Upon successful ignition the flame will be detected by the flame sensor and the ignition spark electrode will be de-
energised.
5.1.6 Should the flame fail to permanently establish during the 25 seconds ignition period, the solenoid valves and ignition
spark electrode will be de-energised and the appliance Ignition Control will go to "lockout" condition.
5.1.7 To repeat the ignition sequence it will be necessary to switch off the electricity supply to the appliance for a period of
10 seconds to reset the ignition control. If a first reset is not successful, wait at least 15 seconds before repeating
the procedure. After reset, an extended waiting time will occur.
5.1.8 If the burner fails to ignite following a second ignition sequence, turn off the gas supply at the gas isolation valve and
investigate the fault.
5.1.9 If gas failure occurs after successful ignition the appliance ignition control will attempt one re-ignition before going to
"lockout" condition.
5.1.10 Ultra HI/LO (e.g. Ultra 7/3.5) only: with the burner ignited, turn down the temperature setting of the second
thermostat (T2-see Fig. 4) and observe that the tile colour changes from bright cherry red to dull red. (Low burn
condition - LO - heat input reduced to 50%). To increase the heat input to 100% (HI), turn up the temperature
setting of the second thermostat (T2).
IMPORTANT: Thermostat T1 must be set at a higher temperature than thermostat T2 to achieve the High/Low
mode of operation.
5.2 Shut Down
5.2.1 To shut down the appliance for short periods of time, switch off the electrical supply to the appliance.
5.2.2 To shut down the appliance for a period of time in excess of one week, switch off the electrical supply to the
appliance and turn off the gas supply at the gas isolation valve.
Note: concise operating instructions are contained on Instruction Label (4260460) that should be affixed adjacent to
a low level user control.
5.3 Checking Gas Pressure
5.3.1 To check the gas supply pressure.
5.3.1.1 Unscrew the sealing screw (2 turns) of the control valve test nipple marked 'IN' and connect a manometer to this test
nipple.
