Yunca Heating Solid Fuel Maintenance Guide
April 2010
Changing the Wegj door
rope is simple.
Remove old rope from the retainer attached to
the front of the fire box opening and insert a
new rope.
1C. BLENZ
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.
When carrying out this work it pays to have
something soft on the hearth (like an
old
pillow), just in case.
Remove the screws
attaching the door rope
retainer to the door casting, the door rope will
stay in the retainer unless it is also needs to be
changed. Remove the glass (if you have
difficulty you may find it easier to also remove
the door handle and undo the lock-nut to allow
the shaft to be extended. Attach the glass seal
to the glass as described in 1A above. Refit the
glass and attach the retainer to the door, taking
care to align the door panel correctly – the door
should openly freely and the panel needs to be
straight.
If the door rope
needs to be changed do so (it
fits very easily into the channel on the retainer).
Adjust
the door handle shaft (see below).
2. DOOR HANDLES and DOOR
HANDLE SHAFTS.
With the exception of the Wegj and the ash doors
(see 2B) of some models, Yunca fires use the
same door handle. The handle is fitted with a
single screw to the shaft.
Door handle shafts
can be adjusted to ensure a
better fit. There are slight design differences for
some models (refer to our online spare parts
information)
http://www.yunca.co.nz/Instructions/index.htm
however the instructions are basically the same.
Always shut a fire door gently as sometimes fuel
may not be fully in the firebox and this may cause
the glass to break.
2A. ALL FIRES (except Wegj).
To open the door, turn the handle up (anti
clockwise) to the “12 o’clock” position and open
the door. To close the door, start with the
handle at 12 o’clock, push the door closed, and
turn the handle down to about the “4 o’clock”
position.
DO NOT FORCE THE HANDLE
to close the
door (or handle may break). If the door is too
difficult to close, try adjusting the door handle
shaft. Similarly if the door handle turns too
easily (past the “five o’clock position, for
example), then the shaft needs to be adjusted.
DO NOT LEAVE THE DOOR HANDLE
in
position over the glass.
There is an easy test to check if your fire door
or ash door is sealing fully.
ONLY TRY THIS IF THE FIRE IS COLD (NOT
going, NO hot or warm embers).
A sheet of paper is placed half in, half out of the
top of the door, and the door is then closed. If
the paper pulls out without tearing, then it is
likely the door handle shaft needs adjusting, or
the door rope may need replacing.
Adjust the shaft
by loosening the locking nut,
then wind the brass bush in (to tighten) or out
(to loosen or remove). Once adjusted, close the
door and check it - too loose and the door
handle will likely be able to keep turning in a full
circle and lack of a tight seal will allow too much
air in, too tight and you risk breaking the
handle. When satisfied that the door is closing
correctly, tighten the locking nut. The rope will
bed in a little, so it is recommended that the
door closure be rechecked after a few fires.
2B. WEGJ DOOR, also BLENZ ASH
DOOR and all QEWB MULTI SERIES
ASH DOOR
Each door handle is fixed by a single screw to
the shaft. A plug (0300P) is available to fit into
the open end at the side of the handle once it
has been fitted.
Should you need to replace the
springs
(0222W) in a Wegj door
it is recommended
that BOTH be changed at the same time to
provide even tension. Access by removing the
door from the fire and follow instructions in 1B
(above). You will find it easier to replace the
glass seal with a new one at this time, rather
than struggle to refit the existing seal.
If there is difficulty closing the ash door (Blenz,
Qewb MF series) try adjusting the catch pin
(0215BQM).
