OPERATING INSTRUCTIONS
stove to ensure that the fire is kept burning. Draught is
caused by the rising hot air in the chimney when the Riva
stove is lit.
Symptoms of poor performance related to flue draught
include: -
• Excessive fuel consumption (high flue draught)
• Poor burning control, overheating (high flue draught)
• Wind noise from air controls (high flue draught)
• Difficulty getting a fire going and keeping it burning well
(low flue draught)
• Low heat output (low flue draught)
• Smoke entering room when doors opened (low flue
draught)
The construction, position, size and height of the chimney
are all factors that affect the performance of the flue
draught.
Other factors that can effect the flue draught include:
• Trees or other buildings nearby causing turbulence
• High and gusty winds
• Outside temperature
• Outside weather conditions
• Incorrect additional ventilation to building
• Blocked flue / chimney
For advice on the correction of persistent flue problems
consult a qualified Solid Fuel heating engineer before
continuing to use the Stockton stove.
9.5 Weather conditions
The weather conditions outside the building could have an
effect on the burning performance of the Riva stove.These
could include:
Windy days - smoking from the appliance. This could be
caused by turbulent airflow around chimney terminal,
possibly caused by the position of other buildings or
obstacles nearby. This problem is, also, sometimes
associated with oversize chimneys, which may even have
downdraught problems on calm days. If smoking is a
common problem on windy days make a note of the wind
strength and direction before consulting your appliance
installer, who will advise you on possible solutions to the
problem, after visiting the installation.
Damp / Rainy days – These sometimes result in problems
when lighting and maintaining the fire, due to the lower
flue temperatures and smaller difference between indoor
and outdoor temperatures reducing the flue draught. Also,
rain water running down the inside of the chimney reduces
the flue temperatures. To help with this problem care must
be taken to use good quality kindling wood, when starting
the fire, and running the stove at a higher heat setting than
normal for a period after start-up to fully heat the chimney.
It could be possible to fit a rain cowl to the chimney to
reduce this problem. Your appliance installer should advise
you on possible solutions.
If the Riva stove emits smoke into the room continuously
close the air controls and allow the stove to go out, and
ventilate the room to clear the fumes. Do not re-light the
appliance until the cause of the problem is identified
and rectified.
