Check For Spillage; Flame Supervision And Spillage Monitoring System - Baxi 940 Installer And Owner Manual

14.2 Check for spillage.

A spillage check must be made before leaving the installed appliance with the
customer. Make this with all the ceramic fuel effect pieces and complete fascia
1. Close all doors and windows in the room containing the appliance.
2. Light the appliance and set the slide control to the maximum burning position.
3. Leave the appliance on for five minutes.
4. The smoke match should be placed horizontally into the convection box at the right
hand side. There is a notch in the black cross member. Insert the tube so that the
neck of its flared end is 5mm passed
and in contact the cross member
(See figure 28).
The installation is satisfactory if the
smoke is drawn into the appliance.
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 inspect the
sealing to the fireplace surround. If
the sealing is satisfactory but the
appliance is installed with the flue
restrictor (See section 8 point 8)
remove the restrictor, reseal the
appliance and retest. If smoke is still not drawn into the appliance 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.
