The Firewarm Stove Ashpan is below the grate, and collects the ash falling through from the burnt fuel.
It must be emptied regularly, as ash building up to the grate can cause
distortion or burning out of the grate bars. A wood fire burns better on a bed
of ash, so if the customer is intending to only burn wood, it will not need to
be emptied as often, but will still need to be emptied so that it does not
impede airflow around the stove.
