The ash level in the ash pan should be checked periodically. The ash pan must never be
permitted to over fill. Under normal operating conditions during the heating season the ash pan
will typically require emptying on a monthly basis. The appliance should never be operated
without the ash pan in position. The ash may be discarded with garden waste or in line with
local waste disposal regulations, after first ensuring that it is sufficiently cool before emptying
the pan. Caution: never attempt to remove the ash pan after the appliance has just
finished operating as it will be extremely hot and injury will result.
The combustion pot should be cleaned on a weekly basis removing any carbon residue.
Vacuuming with a dedicated ash vacuum cleaner is recommended. Failure to clean the
combustion pot as directed may restrict the flow of air within the appliance adversely affecting
its performance.
