14.3 Flame supervision and spillage monitoring system.
This pilot unit includes a system that will automatically shut off the gas supply if the
pilot flame goes out or if there is insufficient oxygen due to spillage or poor ventilation.
Check that the system operates properly as follows: -
!
Light the appliance. Set at the “HIGH” position and leave for one minute.
!
Turn back to “OFF” to extinguish the pilot.
Note the time when the pilot goes out
.
Listen for a snap sound at the gas tap.
Note the time when the sound is heard
.
This
sound is caused by an electromagnetic valve shutting off the gas supply through the tap.
The valve is located in the body of the tap. The valve should operate
within 60 seconds
of the pilot going out
.
If the valve does not operate within this time limit do not allow
the appliance to be used until the fault has been corrected.
This monitoring system must not be adjusted, bypassed or put out of operation.
This monitoring system or any of its parts must only be exchanged using Baxi Fires
Division authorised parts.
15. FINAL REVIEW
1.
Visually inspect the appliance. Clean off any marks incurred during installation.
The
fire should be ‘off’ and allowed to cool completely before cleaning.
Fascia parts.
!
Clean the metal parts with a slightly damp lint free non-abrasive cloth and then dry.
!
Do not use abrasive cleaners as these will scratch the fire surface.
2.
Advise the customer how to operate the appliance. Point out that lighting instruction
details are on the metal plate attached at the bottom of the appliance. Explain to the
customer that the appliance has a flame failure & spillage monitoring system. Point out
the explanation of this system shown in the owner guide under “Operating the fire”.
Advise that if the fire goes out for any reason; wait at least three minutes before
relighting. Stress that if the monitoring system repeatedly shuts off the fire, the
appliance should be switched off and a specialist should be consulted.
3.
Advise the customer that they should read their owner guide before operating the fire
and always follow the advice in the section headed “Cleaning your fire”.
4.
Stress that no extra fuel effect pieces must be added over and above those
supplied with the appliance and that any replacements must only be the authorised
spares. Warn that ignoring this advice could cause incomplete clearance of the
products of combustion with consequent health hazards.
5.
Advise the customer that the appliance will operate to its maximum potential if the
flue is primed during the first 20 – 30 minutes of use. To do this, simply turn the control
to its ‘HIGH’ setting. This will also burn off any carbon deposits that may have formed
during previous use.
If using the appliance for long periods it is beneficial to change between settings. This
