OPERATION
N.B. Before lighting your first fire,
clean the stainless steel flue with a
metal polish and buff. Then wipe
with methylated spirits. This will
eliminate any manufacturing oils and
fingerprints being burnt onto the flue.
It will eventually go a golden coppery
colour.
LIGHTING OF UNIT:
1 Shift the control knob to the fully
open position.
2 Ignite a bed of screwed up paper
and small pieces of kindling or
fire starters.
3 DO NOT USE PETROL OR
OTHER ACCELERANTS TO
START THE FIRE.
4 Once the fire has started,
gradually add larger and larger
pieces of wood until the fire is
established.
5 When the fire is brightly burning,
adjust the control knob to the
desired setting.
Do not run heater for extended
periods on high, or damage may
occur to the firebox, and it will
substantially reduce the life
expectancy of the combustion plate,
fire bricks and air tubes.
Important: For the first 24hrs of
burning, there may be some smoke
and odours present due to the
burning off of light oils and paint
used in the manufacture of the unit.
There is no cause for alarm.
FUEL SELECTION:
The Yunca Woodburner is a very
efficient woodburner. For peak log
burning efficiency we recommend:
1 Use dry, well seasoned soft
wood in your heater. It should be
stacked under cover with good
air circulation for at least nine
months. This allows the moisture
content to reduce and thereby
reach optimum burning qualities.
Remember that green wood can
hold its own weight of water, and
it takes time to get rid of this.
Count on about 6-12 months for
soft woods such as pine to dry
properly.
2 Wet (green) wood will reduce the
efficiency of your heater and
more importantly, will cause a
build up of creosote in the flue,
creating a fire hazard.
3 Larger logs should be split to
assist drying and burning.
4You must avoid:
The use of salt borne drift wood.
The salt absorbed into the wood
reacts with the flame and other
by-products to cause damage to
your heater and its components.
For the same reason, chemical
chimney cleaners should be
avoided, as many of these
comprise a high level of salt in
their make-up.
Chemically treated timbers
should also be avoided. At best
they generally don't burn as well
as untreated timber. At worst,
some of the chemicals may be
noxious and pose a health risk.
5 Don’t burn garbage, plastic or
aerosol cans. It is dangerous and
also reduces the life of your
heater.
Best use of air controls:
Once a good fire is established,
usually after 10-20 minutes, the air
control should be adjusted back until
a slower lazy type flame exists. This
is your most efficient fire with an
effective double burning action and
maximum heat retention.
WARNING: WHEN LIT, ALWAYS
OPEN THE AIR CONTROL
BEFORE OPENING THE FIRE
DOOR.
Due to the clean air requirements, it
is necessary to increase the amount
of secondary air introduced into the
combustion chamber, therefore
reducing the overall banking hours.
Fire bricks will slowly release heat
through the night.
1 Fuel the heater and let it run
about 10 to 15 minutes. Ensure
that the fuel is glowing.
2 Adjust the control knob to low.
3 When increased heat is required,
simply open the control knob to
the desired setting.
COOKTOP:
With the exception of the Wegj
woodburner, the top is designed to
allow you to either cook or keep food
warm. Cooking directly on any
enamel grill top may damage the
surface. The grill top on the Fitzroy
may be removed for direct access to
a cooktop surface.
The cooktop surface of the Hobson
should be treated with a stove
blackening (or high temp paint) from
time to time to keep it looking good.
MAINTENANCE
1 Panels may be easily cleaned by
buffing with a soft cloth. A
foamed or non-abrasive cleanser
may be used for the more
stubborn soiling. Polish
afterwards with a soft, dry cloth.
2 Some residue may appear on the
ceramic glass when the unit is
closed down. Most of this will
burn-off when the heater is
restarted. Use a damp paper
towel dipped in ash and polish
with a clean dry paper towel. If
extra cleaning is required, a
spray foam cleanser is
recommended (rinse well).
Clean only on a slightly warm or
cold heater.
3 When using cleaning materials,
please follow the instructions on
the product label. DO NOT use
abrasives or sharp metal tools
when cleaning your Yunca
Woodburner.
4 Have your Yunca Woodburner
and flue system professionally
checked and cleaned before the
cooler season begins.
Ash clearing:
1 Your Yunca Woodburner is
designed to have a bed of ash on
the bottom of the firebox.
2 Remove ash when required,
remembering to leave a bed of
ash. This will maintain the
efficiency of your heater and
protect the firebox.
3 Ensure that ash is cold and when
it is removed from your heater.
Immediately place outdoors in a
fireproof receptacle with a tight
fitting lid, and locate clear of
combustible materials. Providing
that only untreated wood has
been burnt, ash can safely be
dug into the garden as it makes
an excellent addition to the soil.
SAFETY CAUTIONS:
1 For the protection of young
children install an effective fire
safety screen around your fire.
2 The ceramic glass gets very hot.
It is imperative that small children
are warned of this danger.
3 Flues are recommended to be
cleaned at least annually.
4 Keep door seals clear of any ash
or wood as this may damage the
seals, and result in inefficient
burning.
5 Under no circumstances use a
vacuum cleaner to clean the
heater unless it is totally cold and
has not been used for several
days.
6 DO NOT use flammable liquids
or aerosols to start or rekindle
the fire.
7 DO NOT use flammable liquids
or aerosols in the vicinity of this
appliance when it is operating.
8 DO NOT store fuel within the
heater installation clearances.
9 Remember the “heater-metre”
rule and keep soft furnishings
one metre away from your fire.
10 This appliance should not be
operated with a cracked glass.

SIMPLE MAINTENANCE
WE RECOMMEND THE FLUE AND UNIT COMPONENTS BE CHECKED ANNUALLY.
Replacement of glass, glass seal (packing), door ropes and spare parts. Yunca fires are
designed to allow the owner to carry out simple maintenance work such as the replacement of
fire bricks, combustion plates, air tubes, door handles and shafts, door rope, glass and glass
seals.
For detailed information please refer to the “Spare Parts (Woodburner)” and “Maintenance” files
(download from www.yunca.co.nz under Product Manuals), contact Yunca Heating or their
agents. The Spare Parts guide has a comprehensive listing of spare parts with dimensions and
photographs to aid in the identification of past and present models and their spare parts.
.
FAULTS CAUSE REMEDY
Heavy creosote build up on door
glass
Burning wet wood
Not enough heat in fire bed before
shutting it down
Obtain a dryer wood supply or
further dry out existing wood.
Check flue is clean.
Glass blackening on medium to low
heat setting
Burning wet wood
Not enough heat in fire bed before
shutting it down
Obtain a dryer wood supply or
further dry out existing wood.
Check flue is clean.
Heater unable to be turned down
Clean Air fires are not designed to
fully shut down
Faulty seal on door/ glass Check door / glass seals – replace
where necessary.
Adjust locking nut on door handle
shaft (selected models)
Water booster not performing Liming up of booster
Incorrect installation
Replace booster
Refer to installation instructions
Refer to installer
Water booster making banging
noises
Incorrect installation Refer to installation instructions
Refer to installer
Fumes Flue joints leaking Seal flue joints with recommended
flue sealer. Clean off any creosote
using warm soapy water and
abrasive cleaning pad.
Blocked Flue Have flue professionally cleaned.
Insufficient draw from flue Increase flue height to a minimum of
600mm above the ridge. Extend
flue height if adjacent to nearby tall
buildings or trees.
Fit H-type weather cap if all the
above does not remedy the
situation.
“Blow Back” This happens if too much fuel is
added and smothers the bed of
embers. Gases are building up
before a flame eventually appears
and the gases suddenly ignite. The
result is a short, sharp blast of
smoke from the heater
Add smaller amounts of fuel until
desired fire is reached. Do not
smother the embers.
Ensure there is always a flame
present at all times. (The flame will
eliminate any sudden ignition of
gases).
Soot or creosote fire Build up of soot or creosote in flue Turn heater controls to off.
Call your local fire brigade
This heater has been tested and complies with the requirements of AS/NZS 2918:2001 and AS/NZS 4013
