3.7. Maintenance
The appliance is most efficient when all the surfaces of the
heat exchanger and the ash compartment are clean. If soot
and ashes are allowed to build up, the life of the grates will
be shortened, therefore it is essential to empty the ashpan,

if necessary, daily! Tar and soot build up on the surfaces
of the water jacket and flue passages should be removed
at frequent intervals. This is best achieved by running the
appliance very hot for a short period each day.
It is important to do this in order to preserve the life of the
water jacket.

Action
þ
- The chimney should be checked with a draught meter
and if below the recommended level, look for air leak or a
constantly cold chimney.
- If the connecting flue pipe terminates in a large chimney
and no evidence of air leaks can be discovered. a chimney
liner should be considered.
- If the inadequate draught is due to a poor geographic
position, consult your dealer to consider an electric draft
inducing fan.
þ
- If top flue the appliance should have been supplied with
a draught control box to help regulate the chimney
draught. If the control box gives inadequate control, fit a
draught stabiliser.
- This could be caused by a cold chimney with excessive
heat loss but it is more likely that the cause is turbulence
at the chimney terminal.
Raise the height of the chimney or fit a suitable cowl.
- Condensation is often mistaken for a leaking water jacket
and can be very persistent. Each water jacket is tested
thoroughly in the factory and it is highly unlikely that a leak
could be the cause.
Condensation is caused by :
- A poor chimney which allows the flue gases to cool
rapidly, thereby condensing steam in the flue.
