Capital Sirius 490MF Installation And Operating Instructions Manual page 18

Recommended Fuels
Please note that HETAS Ltd Appliance Approval only covers the use of wood logs
and approved smokeless fuels on this appliance. HETAS Ltd Approval does not
cover the use of other fuels either alone or mixed with the recommended fuels
listed above, nor does it cover instructions for the use of other fuels
Wood ‐ Only kiln‐dried or well‐seasoned wood with a moisture content reading
of less than 18% is recommended. A Capital moisture meter is a handy device to
have and is available from your supplier. As a rule‐of‐thumb, wood seasons at
about 1" (25mm) per year, so a log split such that along its length no dimension
is greater than 3" (75mm), it would take about 3 years to dry. A dry log will
produce up to four and a half times more heat output than a freshly cut log.
Wet logs take heat to dry.
Other Solid Fuel – "Authorised" fuels include anthracite large nuts, briquettes
smokeless fuel, ie. Ancit, Phurnacite, Taybrite, Homefire Ovals suitable for closed
appliances. Bituminous coals can cause tar deposits and burn very hot, so mix
with other fuels and use sparingly.
Unauthorised Fuels
DO NOT burn Wildfire, Housecoal, household coal, petroleum cokes or
household waste. If in doubt consult your merchant or the Solid Fuel
Association.
Please note that when refuelling with solid fuel, do not pile fuel higher than 30
degrees from the front bar rearwards – over‐fuelling can cause excess smoke
and produce temperatures beyond the designed rating of the appliance causing
damage to internal parts.
This appliance is designed to be operated with the door closed, except for
refuelling. Not only is it unsafe to operate with the door open but the appliance
efficiency will be significantly reduced and excess smoke can occur.
The stove is designed to operate intermittently and must not be used as an
overnight burner.
