CHECKING FOR SPILLAGE
CAUTION - Whilst checking for spillage care must
be taken to avoid touching hot panels.
Ensure that all doors and windows are closed.
IMPORTANT NOTE: If there is a ceiling or
extractor fan in the room or adjoining room then
the spillage test must be performed with the fan
turned on and any interconnecting doors between
the fan and the appliance left open.
There are two stages of appliance operation for which
spillage must be checked by following "the spillage
checking procedure" shown below.
STAGE 1 - Operate the fire on maximum for five
minutes and check for spillage. If spillage is evident
then the fire is operated for a further 10 minutes and
re-checked. If spillage is still evident then the cause
should be ascertained and rectified before continuing
with commissioning.
STAGE 2 - Following a satisfactory result at stage 1,
the fire is left on and the boiler is operated for 5
minutes before checking for spillage again. If spillage
is evident then the cause should be ascertained and
rectified before continuing with commissioning.
If the appliance cannot be commissioned then it
should be isolated until the problem is resolved.
THE SPILLAGE CHECKING PROCEDURE
Checking for spillage is only possible from the left
hand side of the appliance. A lighted smoke match
with extension is inserted into the boiler canopy and
positioned just below but not touching the fire flue
spigot. With the aid of a torch the trail of smoke from
the match is observed. If the smoke is not being
drawn up into the flue then spillage of combustion
products is indicated.
POSSIBLE CAUSES OF SPILLAGE
The smoke match may have been positioned
incorrectly, resulting in the smoke being picked up by
hot convected air currents.
The builders opening or flue installation may be
unsound.
Inadequate ventilation.
Down draughts may be present.
The flue may be blocked.
