Yunca Heating Solid Fuel Maintenance Guide
April 2010
Yunca Woodburners and Multifuels feature
very similar basic designs throughout the
range, so when it comes to maintaining
your fire the same procedures may be
followed for different models.
To assist with identifying fires and associated
spare parts, please
refer to the online spare
parts (woodburner, multifuel) guide:
http://www.yunca.co.nz/Instructions/index.htm
Yunca recommends you regularly check your
burner to ensure optimum performance. To
save on maintenance costs there are a
number of procedures that, with due care and
attention, can be carried out by the owner.
This includes the following:
-
replacing the glass / glass seal
-
replacing the door rope / ash door rope.
-
replacing the door handle / door handle
shaft
-
replacing firebricks / combustion plates / air
tubes
The following is a guideline to assist with
some of these tasks.
Remember that your safety is paramount, so if
there is any doubt please contact your local
Yunca agent or a service firm (maintenance
may also be carried out by the same firm that
offers chimney cleaning, for example).
Yunca recommends that the flue system is
checked and cleaned annually.
1. REPLACING THE GLASS,
GLASS SEAL and DOOR ROPE
Glass may be cleaned
by dipping a damp paper
towel in ash and wiping the
cold
glass. Buff with a
clean, damp paper towel. Glass may blacken
when a fire is turned down, and this will normally
burn off when next operating at a higher
temperature.
If there is a very sticky, dark deposit on the glass
this is creosote, caused by burning wet wood or
not having enough heat in the fire bed before
turning the fire down. Creosote may be difficult to
remove. Avoid scratching the glass. Avoid harsh
chemicals or the glass may become pitted. Should
you use ANY cleaner on the glass, you must rinse
well before use.
Avoid creosote build up by ensuring your firewood
is well seasoned. Creosote can also cause
chimney blockages.
N.B
. When door / ash door rope has been
replaced it will be necessary to adjust the door
handle shaft (where fitted). Refer to section 2.
1A. “NEW MODEL” MULTIFUEL FIRES
(FREESTANDING & INBUILT), HOBSON,
FITZROY, QEWB (except QEWB2000),
and QEWB VARIANTS (FOCUS,
RADIANT, etc).
(Wegj and Blenz: Refer 1B, 1C).
You may leave the door frame in place on the
fire when changing glass, glass seals and
ropes. It is not advisable to reuse old glass seal
as it may not give an adequate seal and it will
be very difficult to fit without adhesive.
