Yeoman DEVON 50 - Manual (Page 13)

16. seasonal use
16.1 Clean and service the appliance if it is not used during the
warmer periods of the year as detailed in the Maintenance
and Servicing section.
16.2 Set the air controls 50% open to keep the appliance
ventilated and stop the build-up of any moisture inside.
16.3 Before re-lighting the appliance:
—
Remove the baffle.
—
Clear any debris that may have accumulated.
—
Check the flue is clear of any blockages.
16.4 If this appliance is unused for lengthy periods of time it
should be periodically checked to ensure that condensation
is not building up within the stove.
note – tHIs condensatIon Is noRMal and does
not IndIcate a Faulty oR leaKInG stove .
16.5 If the stove is going to be unused for very long periods of
time it is recommended to drain the system.
17. tRouBlesHootInG tIPs
17.1 stove glass blackening
This has four possible causes:
1. Incorrect use of airwash
See User Instructions, Sections 1, 4 and 5 for the correct
use of the air controls.
2. Burning unseasoned wood
See User Instructions, Section 3 to identify when wood is
ready for burning.
3. stove operated at too low a temperature
A stove pipe thermometer can identify this problem (Stovax
part no. 3046). the ideal working temperature range is
130°C - 250°C (270°F - 480°F). Failing to close down the
Primary Air Control once the appliance has heated up to
this range may cause the appliance to exceed the ideal
temperature range and to over-fire. Over-firing can cause
permanent damage to the appliance and invalidates your
warranty. Burn with the Airwash Control fully open for
approximately 20 minutes to cure this.
The problem may be caused by damping down the
appliance during periods of extended burning.
4. Problems with the flue, in particular insufficient air pull.
If the flue is not working efficiently the glass can blacken.
A flue which has too much downdraft may be too short,
needs lining, or has too many bends. This can also cause
blackening of the stove glass. Contact the installer or a flue
specialist for advice.
17.2 Riddling mechanism jamming
This occurs when fine ash builds up under the riddling bars
preventing movement. To prevent this:
—
Follow a regular cleaning routine for the inside of your
appliance.
—
Lift out the riddling mechanism and remove all ash.
—
Replace riddling mechanism when cleaning is complete.
17.3 Glass cracking
Do not over tighten the screws on the glass clips when
replacing the glass. This causes stress and the intense
temperature changes can cause the glass to crack. For
replacement glass contact your local Yeoman retailer.
17.4 appliance is producing tar
This can be identified by:
—
A very strong pungent smell shortly after the appliance is
lit and heats up.
—
Glass blackening.
—
Thick, brown, sticky tar oozing from the pipe joints.
This is caused by burning damp wood and running the
appliance at too low a temperature.
Use well seasoned wood and operate the appliance within
the ideal temperature range.
tar is a major cause of chimney fires . If the appliance
experiences problems with tar build up consult a chimney
sweep before continued use of the appliance.
17.5 all or some of the radiators do not get hot
Burning wood Wood is burning too
slowly
Open up the airwash to make
a hotter fire
If fitted set the thermostat to a
higher setting
Burn dryer wood
Burn better quality wood
Reduce ashbed to 1" thick
Burning Solid
Mineral fuels
Fuel is burning too
slowly
Open up the primary air to
make a hotter fire. If fitted,
set the thermostat to a higher
setting
The fire needs riddling to
remove ash. De-ash the fire
Empty the ash pan.
All Fuels
Stove is not producing
much heat.
Not enough fuel.
System faults
Bleed the radiators to ensure
there are no air locks.
Incorrect system design seek
professional assistance
Too many radiators in the
system exceeding the stoves
capabilities.
17.6 In the unlikely event of a problem that cannot be solved
by these tips contact your installer or retailer for help.
