maximum output.
2. After checking, turn off the appliance. Remove the pressure gauge and replace the
test point sealing screw.
3. Relight the appliance. Turn to the maximum output position and test around the
sealing screw for gas soundness with a suitable leak detection fluid.
Check for spillage.
1. Close all doors and windows in the room containing the appliance.
2. Light the appliance and turn the control knob to the 'HIGH' position.
3. Leave the appliance on for five minutes.
4. A smoke match should be placed close to base of the diverter box. The installation is
satisfactory if the smoke is drawn into the appliance/ flue way. Do not use a lighted
match or a naked flame.
If the smoke is not drawn into the appliance leave the appliance alight at the maximum
setting for a further ten minutes and then repeat the test. If the smoke is still not drawn
into the appliance then disconnect the appliance and seek expert advice.
5. 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.
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. 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.
