Eureka The Eureka Cooker User manual

• Smoke entering the room from the firebox when the door is open may be caused by
• Insufficient length of flue (Flue to be 4500mm minimum from underneath base of heater to underside of cowl)
– Increase height of flue.
• Flue Downdraught
– Consult dealer or increase height of flue.
• Creosote Build up in flue
– Remove cowl and clean flue as per cleaning instructions. Check moisture content of wood.
• Excessive ash build up
Some woods will give large amounts of ash despite how you run the heater. Others will give you very little. Use the
wood which is most convenient for you as long as it is dry. After a period of time you will get to know when to
empty your unit. Always leave 12mm of ash in the bottom of your heater. Bark will give you excessive ash. Try not to
burn it.
If you are burning wood that gives you charcoal, you may find that after running the heater say for 8 hours at
maximum burn rate, the charcoal builds up excessively. Overnight burn will reduce this charcoal back to a fine ash. If
you are not ready to shutdown for overnight burn when you next fuel the stove, load the stove with only one piece
of wood and lay it across the firebox on top of the charcoal. Open the air control wide open and you will find the
charcoal will burn down with the one piece of wood. Repeat the process until the ash level is significantly reduced.

Troubleshooting
!
WARNING
NEVER OPERATE THE COOKER WITH THE DOOR LOOSE AND NOT AIR TIGHT.
OVERFIRING COULD RESULT IN DETRIMENTAL WEAR AND TEAR ON THE
FIREBOX.
• Air Control Jamming
There are three bolts holding the air slide control in place. Undo them and remove the air slide.Wipe any ash or dust that
may have accumulated on the back of the air slide or on the face of the heater. If any burrs have developed on the back
of the air slide or on the face of the heater, rub them off with fine wet and dry sand paper till you have a smooth surface
and edges. Replace the air slide and make sure the washers and spacers are on the bolts when you screw the bolts back
into the face of the heater. Do not apply any type of lubricant to the air slide whatsoever as this will attract dust and
make the slide stick.
• No Overnight Burn
Remove the air slide as per air control jamming and check that the air slide is hard against the face of the heater. If it is
loose, tighten up the bolts holding the air slide to the face of the heater. Do not overtighten.
Check that the door rope has an even indentation from the sealing strip, which is on the face of the firebox. If it is uneven
and it appears as though air could leak through the seal, adjust the thickness of the door rope to suit. Stretch the rope to
make it thinner where the indentation is the heaviest and bunch up the excess where the indentation is smaller.
Check the four bolts that hold the glass retainer in position. If loose tighten. Do not overtighten.
The door may become loose through the door seal shrinking.To tighten the door, open the door and look at the inside of
the door catch.
(a) Unscrew Allen key screw in door handle shaft.
(b) Rotate door handle anti-clockwise (when looking from front of heater). This will tighten door rope seal.
1 turn = approx. 1mm.
(c) Close door and lock.
(d) Check for seal around door opening.
(e) Replace Allen key screw.
(f) Check that roll pin is central in shaft.
When closing the door you should now feel firm resistance when the roll pin comes into contact with the catch.
Note: Not all woods will last overnight.

WARNING
Your cooker is coated with the best available heat resistant paint. Even though
the paint has been baked after application, it may require further temperature
curing. It may, if you overfire the heater on its first fire, discolour. For your first
two or three firings, never exceed medium air setting. Do not wipe the heater
while paint is curing. After the paint has cured the only maintenance required to
maintain the heaters finish is to wipe it with a soft cloth. Do not use any
commercial cleaners or solvents on the paint finish.
We are proud of the presentation of our products. If at any time you need to
freshen up the paint finish, your local dealer has touch up paint available for
purchase. You may even change the colour of your cooker if you wish.
If you have any enquires, please contact the dealer from whom you purchased your heater:

Safety Warnings
!
WARNING
Leaving Door Open
As stated previously in relation to leaving door open 25mm to encourage the fire
to pick up at a faster rate. Your heater has been tested to ensure that no
structural damage can take place if the door is inadvertently left open. However
your paint finish can be damaged if the door is left open for a long period with a
full firebox of fuel with the fan off. Closely supervise your heater while the door is
left open.
Closing the Door
Always ensure that before you close your door there is no wood protruding
beyond the front of the firebox opening. Do not use the door glass as a ’battering
ram’ to push the wood back into the firebox. Damage to the glass by such
impact is not covered by your warranty.

Operating your Eureka (Continued)
Overnight burn
Approximately 30 minutes before turning the heater down to overnight burn it is recommended to load the heater with
fuel for the overnight burn. Leave the air control in the medium to high position. Let the heater run for about thirty
minutes.This will reduce the moisture content in the fuel before shut down. (This will help reduce the creosote formation
in the firebox and flue.) Set the air control to the setting you have found best for your requirements. The aim when
overnight burning is to have only a few hot embers left in the bottom of the firebox in the morning. Not huge lumps of
wood. Note: Not all woods will last overnight.
Cleaning your flue
Carefully remove baffle plate and put it to one side. Close the firebox door, and position flue damper control in the open
position using the flue damper control handle. Obtain a 150mm dia. flue brush from your local Eureka Dealer and
proceed up onto your roof. Remove the cowl. Slowly push the flue brush down the chimney until it stops. Pull the brush
back out and repeat the process. Each time you do this you will notice that the brush will go further down the chimney
till it reaches the bottom. The soot and creosote will fall down the chimney and into the firebox. Clean residue from
firebox. Replace the baffle plate. Make sure you do the job well.The cleaner the flue the less chance there will be of the
creosote sticking again. After you have replaced the cowl, inspect the roof flashing for any damage that may have been
incurred whilst you were cleaning the flue. Reseal the seal on the roof with roof and gutter silicone if required.
Cleaning the soot tray & internal side panels
The soot tray & the internal cavity each side of the cooker should be cleaned at regular intervals in the following manner:
1. Open oven door.
2. Remove bottom panel below oven door (held by 2 screws).
3. Unscrew the 2 knobs & remove cover.
4. Slide out the soot tray & give it a good clean.
5. Using the L shape scraper tool supplied, slide tool up between the firebox side & wrapper panels. Remove creosote
using a sweeping motion. Repeat for opposite side.
6. Make sure all soot & creosote has been removed from all surrounding areas including the tray cavity.
7. Replace tray & panels.
Operating your oven
When ready to start cooking in your oven make
sure there is a good fire burning in the firebox.
Move the flue damper control forward to the
closed position for oven use.
To regulate the temperature in the oven:
(a) Move the air slide control in (cooler) or out
(hotter) to the required setting.
(b) Remove and place to the side 1 or 2 of the
air hole covers on top of the cooker using
the tool supplied.

!
WARNING
DO NOT ATTEMPT TO OPERATE THIS APPLIANCE WITHOUT READING AND
UNDERSTANDING THESE OPERATING INSTRUCTIONS THOROUGHLY. FAILURE TO
OPERATE THIS APPLIANCE PROPERLY MAY CAUSE UNDUE DAMAGE TO THE
APPLIANCE OR RESULT IN A FLUE FIRE.
Take the firebricks out of the heater. They are to be placed
so that they stand on end against the rear and two side
walls of the firebox. You will notice that the bricks have a
bevel on one end.
Inside the firebox there is a “C” shaped angle iron firebrick
retaining bracket.This is designed to sit over the bricks and
hold them in place.This should be placed in the firebox so
that you see a flat face of the angle iron on both sides of
the firebox and at the rear of the firebox.
Holding the “C” frame up to the top of the firebox, insert a
whole firebrick, standing it vertically with the bevel edge
pointing down and facing inwards toward the left hand side
of the firebox. Lower the left hand side of the “C” frame
onto the firebrick. Repeat with a whole firebrick on the right hand side.
Place firebricks (2 whole firebricks and one half firebrick) using the same method against the back wall of the firebox.
Now place one extra half firebrick on either side of the firebox to complete the installation of the firebricks. (i.e. two each
side and remainder on the back wall.)
Push each brick and “C” frame firmly against the wall of the firebox.
Sand Layer
Place a 12mm (approx) layer of sand in the bottom of the heater. (Provided in the installation kit.) This is required for the
first fire.Thereafter, when cleaning out the firebox, always leave the equivalent amount of ash in the bottom.
Baffle Plate
Operating your Eureka
Your first fire
Before starting your fire ensure oven door is left open for the first three fires for paint curing of oven.
Starting your fire
Place a firelighter or paper in the bottom of the firebox and place a large amount of small kindling on top. Ignite the
paper or the firelighter. Set the air control to high and leave the main door open approximately 25mm. With flue damper
control in open position (refer illustration on page 6 for flue damper control location). When the kindling is burning, place
about four pieces of small wood on top of the burning kindling. Once the wood is alight, close the main door. After
approximately 20 minutes, turn the air control down to medium.
On the initial fire up you may detect smoke coming from the paint finish and from any oils that may be on the steel on
the outside of the firebox. This is normal. It is suggested to well ventilate your home on the initial fire up. Please refer to
our section ‘Paint curing and cure’.
The glass door
Always operate your heater with the firebox door closed and locked. The only time you can leave the firebox door open is
on initial lighting, or when reloading the heater.
Care of your glass
If you are burning good dry wood, you will have very little discolouration of your glass in normal burning cycle. If you aim
for an eight to ten hour overnight burn, you should not get much discolouration.You can control this by adjusting the air
slide control, moving from the left and slowly creeping the control to the right.After a number of days you will find the
right position to suit your requirements and the fuel that you are using.
Cleaning the glass
Generally the only time you will possibly need to clean your glass is after a long overnight burn. If you find that you have
a wet sticky black film on your glass (creosote), it is better to burn the heater as normal for one load of wood.When the
wood has burnt down to a hot bed of embers, open the door and leave it wide open until the glass cools sufficiently to
be wiped with a damp cloth. This should clean all the white smoky film off the glass. Creosote on the glass is normally a
sign that you have tried to get too long an overnight burn or you have burnt excessively wet or green wood.If the film on
the glass won’t come off with a wet cloth, you can use wet ash from the ash bed as a cleaner or commercial products
such as Crystal Clear, Johnson Foam Clean or Windex.
Normal Operations
When you get up in the morning, open up the air control of the heater to high position to start the embers glowing. Place
three or four pieces of wood on top of the embers and leave the door open 25mm. Once the fuel starts to flame close
the door. As the heater starts to heat up (approx 20 minutes) begin reducing the air control towards a lower setting. You
will find you will only need to run the heater between low and medium to maintain the temperature you desire in your
home.
For best results it is best to burn 250mm long wood and load your wood straight into the firebox front to rear. This will
give optimum efficiency and recoverable heat, and minimise creosote formation and smoke emissions.
