appliance and seek expert advice.

6.

If the above test is satisfactory, open all internal connecting doors, hatches, etc., in the

room.  Keep all doors and windows that open to the outside of the building closed.
Recheck for spillage as above.  If an extractor fan is installed in the same room as the
appliance or a connecting room, check that spillage does not occur with the fan
operating and all doors and other openings between the fan and the appliance open. If
the smoke is drawn into the appliance, continue with the installation.  If the test is not
satisfactory, 

disconnect the appliance and advise the customer of the cause of

failure.

14.2 Flame supervision and spillage monitoring system.

The pilot unit incorporates 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 lack of
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.

2.

Advise the customer how to operate the fire.

3.

Explain to the customer that the appliance has a flame failure and spillage monitoring

system. Point out the explanation of this system shown in the owner guide.
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. Point out that the
lighting instruction details are on a metal plate attached at the bottom of the appliance.

4.

Advise that the fire may give off a slight odour while new.  This is quite normal and

it will disappear after a short period of use.

5.

Advise that any cleaning must only be carried out when the fire is off and cold.

6.

Advise the customer that they should read the owner guide before operating the fire

and always follow the advice in the section headed “Cleaning your fire”.
