Maintenance

Troubleshooting

The chimney should be swept at least

once a year together with the flue pipe

connection. Care should be taken to

ensure that there is not a build up of

soot on the baffle and in the airways of

the appliance. 

If the appliance has not been operated

for long periods, the flue should be

inspected and swept before use to

ensure there are no blockages within the

flue.

The grate should be cleaned regularly

and the ashpan emptied daily. 

Never allow the ash in the ashpan to

overfill allowing ash to be in contact

with the underside of the grate. 

This will overheat the grate and cause

premature wear and distortion. 

• The internal vermiculite panels of the

appliance should be checked regularly

for soundness. If any wear and tear is

found, we recommend these parts are

replaced immediately. 

• Check the rope door seals are intact

and are not worn. These should be

replaced on an annual basis to ensure

the correct operation of this appliance. 

• The glass can be cleaned using a soft

damp cloth or a ceramic glass cleaner

(available from your local stockist)

Use only replacement parts

recommended by the manufacturer.

We recommend that the appliance is serviced annually by a competent

engineer to ensure it’s continued safe operation.
