4.9 Commissioning
The fascia must be attached to the unit when testing the flame picture and is to be
tested for a minimum of 30 minutes ensuring that the pilot thermocouple is not too
sensitive also checking all of the lighting systems e.g. The Remote Control,
Hardwire switch testing the high and low flame rates.
Light the fire
see ‘Gas Fire User Instructions’ and ensure that the pilot lights
constantly and the pilot flame envelopes the thermocouple. The pilot should hold
in for 20 seconds, before lighting the main burner.
TEST THE GAS PRESSURE. Turn the fire on full; attach a manometer to the
inlet test point and ensure there is a pressure of 20mbar (+/- 1mb) for natural gas
appliances or 37mbar for propane appliances. Now turn on all the other gas
appliances in the house and re check pressure. The pressure must still be in the
tolerance of +/- 1mbar. Now turn off all the other gas appliances and turn the fire
down to pilot only, the pressure must still be in the tolerance of +/- 1mbar. If it is
not, TRANSCO, BORD GAIS or the propane supplier must be called to adjust the
governor to the house before the fire can be commissioned further.
A combustion analysis check to establish the correct operation of the appliance
should then be carried out. Using an analyser to BS7927, first zero the equipment
and sample the entire width of the combustion product outlet. Under normal
conditions after 30 minutes of operation, the levels of CO/CO2 at high rate should
be 5ppm CO and 0.43% CO2 and the low rate should be 3ppm CO and 0.29%
CO2 (depending on the accuracy of the analyser used).
If the combustion is suspect, disconnect the appliance and contact the
manufacturer.
Due to the newness of the materials, the fire may give off a slight smell for a
period of time after commissioning. This is quite normal and any odours
should disperse within a few hours of operation.
Brief the customer on the operation of the appliance and give them the
instructions. The customer must be told of the need for regular servicing of the
appliance, this will be at least once a year, and be made aware that no rubbish is
to be thrown onto the fire bed.
The customer must also be aware that purpose provided ventilation should
be checked regularly.
If you have any questions or the fire is not operating correctly, call the
C V O studios BEFORE you leave the installation.
If the appliance is not fitted in strict accordance with these instructions,
C V O cannot be held responsible for any damage caused and reserves the
right to charge for any corrective work.
Oxygen depletion sensor
There is a highly sensitive oxygen depletion sensor designed into the pilot light. If
any part is damaged the entire unit must be replaced. Do not attempt to bend or
alter the flame head, thermocouple or aeration hole. Use only genuine spare parts
as similar looking parts from other appliances may well give different or inferior
performance and could lead to a hazard.
