Preliminary Installation Procedures for
WAGENER SPARKY RU – Rural Woodburner
To get the full benefit from the Wagener Sparky RU Woodburner it is important that it is installed correctly,
both for efficiency and safety sake. The following points should be noted:-
1. The characteristics of the Wagener Sparky RU will determine its position within the home.
As a general rule an interior wall installation suits flue requirements better than against an exterior
wall.
2. Check for flue obstructions above the ceiling. (header tanks, electrical mains or load bearing roof
supports and the like).
3. The recommended vertical flue height for optimum operation is 4.2metres above the top of Sparky
RU’s Flue Collar Panel. The performance of Sparky RU depends more on the flue than on any other
single component. It is the draw on the flue that drives the stove.
4. Remember a permit is required from your Local Authority.
Flue System
Must be manufactured in accordance with AS/NZS 2918-2001 and tested to Appendix F.
See installation instructions on pages 4, 5 & 6.
PLEASE NOTE: A purpose designed and tested petite flue system is available for Sparky RU
using a 100/150/200mm system with a reduced flue shield and ceiling plate.
Flue Shield
Sparky RU requires a single flue shield standing 1000mm high and spaced 30mm above the flue collar panel.
Please refer to fitting instructions supplied with the flue shield.
Floor Protector/Hearth Requirements & Positioning
Sparky RU requires an ash hearth floor protector only of a minimum size of 610mm wide and 865mm
deep. (eg Tiles, slate, treadle plate etc)
The Ash Hearth floor protector shall have an upper surface, including grouting if required, of a durable,
non-combustible material.
All joints in the surface must be sealed to protect and prevent ash or spilled embers reaching the floor.
Floor protection must extend under Sparky RU and forward 300mm and be 200mm from each side of the
firebox door opening. (120mm from the side panel to each side)
For concrete floors trim back any floor coverings to no less than the minimum hearth requirement.
NOTE: SPARKY RU MUST BE AFFIXED TO THE HEARTH AND FLOOR FOR SEISMIC RESTRAINT.
For Seismic Restraint secure through two holes at the rear of the log box base and screw through the hearth
and into the floor.
Wet Back Fitting
Sparky RU can be fitted with a wet back. We recommend that you use the “Lion” Wet Back which has been
designed and tested specifically for Sparky RU. In general, wet backs are factory fitted at the time of ordering.
However, a suitably qualified person can fit or change the wet back out in the field if this is required. Water
MUST always be present in the wet back. The wet back MUST be connected by a Registered Plumber to an
open vented system. Tempering valves are required. Please check the PH level of the water supply as wet
backs can become fouled with lime which will void the warranty. NB Some coals are very corrosive and may
shorten the life of the wet back – please check with the supplier as this is NOT covered by warranty. Please
advise the householders NOT to boil the wet back as this will cause vibrations and will fatigue the wet back,
the pipes and the cylinder. This will NOT be covered by the warranty.

2918:2001. THESE INSTALLATION INSTRUCTIONS ARE FOR TESTED APPLIANCES
ONLY.
CAUTION: MIXING FLUE SYSTEM COMPONENTS FROM DIFFERENT SOURCES OR MODIFYING THE
DIMENSIONAL SPECIFICATIONS OF COMPONENTS MAY RESULT IN HAZARDOUS CONDITIONS.
WHERE SUCH ACTION IS CONSIDERED, THE MANUFACTURER SHOULD BE CONSULTED IN THE
FIRST INSTANCE.
CAUTION: IT IS THE RESPONSIBILITY OF THE INSTALLER TO ENSURE THAT THE INSTALLATION OF
THIS FLUE KIT COMPLIES WITH AS/NZS 2918:2001, THE APPLIANCE MANUFACTURERS
SPECIFICATIONS FOR FLUE PIPE SHIELD AND CEILING PLATE AND THAT THE RELEVANT BUILDING
CODES ARE ADHERED TO.
BENDS AND EXTENSIONS TO THE LENGTH OF A FLUE SYSTEM ARE PERMITTED (AS/NZS 2918:2001 4.1)
1. Locate Woodburner in its proposed position and mark a point on the ceiling that is directly above the
centre of the Woodburners Flue Spigot. Check that the Woodburners location allows the OUTER CASING
to clear all the structural roof timbers.
2. Cut a 200mm square hole in ceiling, directly above a cut hole in roof to accommodate OUTER CASING.
3. Fit timber nogs around ceiling i.e. Nogs form a 200mm square aperture that allows air to circulate freely
over the OUTER CASING surface.
4. Position the OUTER CASING so that it is flush with the underneath of the ceiling and protrudes through
the roof the required height. Note that AS/NZS 2918:2001 4.9.1(a) states, “the FLUE PIPE shall extend not
less than 4.6m above the top of the floor protector.” Refer to Diagram B. Fix into position using appropriate
fastenings.
a) If the FLUE PIPE is within 3 metres of the ridge, the FLUE PIPE must protrude at least 600mm above the
ridge of the roof.
b) If the distance from the ridge is more than 3 metres, the FLUE PIPE must protrude at least 1000mm above
roof penetration.
c) The FLUE PIPE must be more than 3 metres from any nearby structure. (Refer to diagram C).
Additional FLUE PIPE, OUTER CASING and/or INNER CASING may have to be added to ensure the
following.
•The correct minimum roof penetration height.
•Sufficient overall height to encase the FLUE PIPE which must extend a minimum of 4.6 metres from
the floor protector. Refer to diagram B.

100mm / 200mm Free Standing Woodburner Flue Kit
Installation Instructions (continued)
Note that the INNER CASING MUST extend 200mm above roof penetration.
NB: Do not secure the OUTER CASING SLIP EXTENSION onto the OUTER CASING, as a final adjustment
will be required when fitting cowl assembly. See paragraph 11.
5. Fix an appropriate flashing around the OUTER CASING to seal onto the roofing material. Refer to the
manufacturer’s recommendations for correct fitting. NB: On iron roofs, fixings such as metal angle brackets
(approximately 25mm x 25mm) can be fitted under the flashing to securely fix the roof to OUTER CASING.
6. Place CEILING PLATE over Woodburners Flue Spigot, ensuring the folded edges are facing the ceiling.
7. Position bottom length of FLUE PIPE (crimped end downwards) into Woodburner Flue Spigot.
Ensure the connection is well sealed using a suitable flue pipe sealant such as maniseal fire cement.
8. Assemble FLUE PIPES together ensuring seams are straight, offsetting the seams will ensure a neat fit. FLUE
PIPES must be assembled with crimped ends down (towards Woodburner). Secure each joint with a
minimum of three Monel Steel Rivets equally spaced around the joint. If using HI-THERM FLUE PIPE the
protective wrapping should be left on the FLUE PIPE during installation.
9. From the roof lower FLUE PIPE through OUTER CASING into the bottom FLUE PIPE securing the 3
Monel rivets.
10. Check that the FLUE PIPE SPACING BRACKETS inside the INNER CASING are correctly positioned and
then from the roof slide the INNER CASING into the OUTER CASING until the brackets rest on to the
internal swage ring of the OUTER CASING, this will ensure the INNER CASING is the correct 12mm above
ceiling level.
Check the INNER CASING when correctly positioned extends a minimum of 200mm above the roof
penetration.
11. Before securing the OUTER CASING SLIP EXTENSION to the OUTER CASING with 3 rivets, ensure the
FLUE PIPE is either flush or extends above the top of the OUTER CASING SLIP EXTENSION by no more
than 15mm. Adjust SLIP EXTENSION to obtain this measurement.
12. Push CASING COVER (with spigot inside FLUE PIPE) down onto the OUTER CASING SLIP
EXTENSION. The 3 locating brackets with holes must be on the outside of the OUTER CASING SLIP
EXTENSION and are secured using 3 rivets.
13. Fit COWL but do not secure, as removal for flue cleaning will be necessary. Deform or ovalise the stub of
the COWL to ensure it is a tight friction fit.
14. Fasten CELING PLATE to ceiling using screws and ceramic spacers required. Ensure an even air gap
around FLUE PIPE when fixing. Remove protective plastic from CEILING PLATE N.B 12mm air gap between
ceiling plate and ceiling must be maintained.
15. Using brackets provided fit the flue shield to the rear of the flue pipe with a 30mm gap between the stove
top collar and lower edge of shield. (See diagram page 4)
16. Please leave all instructions with the owner.

9. CAUTION: THE USE OF SOME TYPES OF PRESERVATIVE TREATED WOOD AS A FUEL CAN BE
HAZARDOUS TO THE ENVIRONMENT AND DETRIMENTAL TO YOUR APPLIANCE.
Further Cautions & Over Firing
Never run Sparky RU with the door ajar or open. This will cause over firing and damage to your
stove & flue which will NOT be covered by warranty as well as being potentially dangerous.
SIGNS OF OVER FIRING: Flue turns red hot, stove “roars”, cooktop surface becomes red hot.
POSSIBLE CAUSE OF OVER FIRING REMEDY
1. Excess flue length/ windy conditions Move Air Control to reduce or close air supply
2. Appliance run with door ajar Close the door
3. Faulty door seals Replace faulty door seals
4. Full load of very dry, small wood Don’t load excess quantities of fuel
5. Dirty flue catches fire Close Air Supply. Call fire brigade if necessary.
Inspect & Clean Flue when cold.
Review quality and type of fuel being used.
Sparky RU is HOT while in operation and caution is required as contact may cause burns.
CREOSOTE OR SOOT FIRE: In the unlikely event of a soot or creosote fire occurring FIRST Alert
occupants and ensure their safety then see Remedy 5 above.

2021

Operating WAGENER SPARKY RU – Rural Woodburner
Dry, seasoned wood at less than 25% moisture content should be used at all times.
Try to buy wood well in advance and store so that the air can circulate through the pile to assist drying.
Wet, unseasoned wood can cause creosote problems, especially if it is burned slowly. Care should be taken
to ensure that the fire is actually burning and not just smouldering which over a period of time can create
creosote build-up and flue blockages.
DO NOT burn driftwood, chipboards, painted, stained or treated timbers or glossy print material as they
will all damage your Sparky RU and flue and void your warranty. Coal must not be used in this fire.
NOTE: The heat output level of Sparky RU is controlled not only by the air control but also by the type and
quality of fuel in the firebox. For best results the fuel should be loaded front to back.
Fire bricks can hold moisture and may crack in a hot fire. Have 2 or 3 small fires to “condition” bricks or
alternatively bricks can be removed and dried in the sun or hot water cupboard.
When Sparky RU is not in use close the air control to prevent the fire drawing air back down the flue
and into the firebox as moist or salt laden air can cause deterioration of the appliance over time.Cleaning out
the firebox at the end of winter usage and spraying the inside steel box with CRC can prevent surface rusting.
First Burn on a New Appliance or Repainted Appliance
On INITIAL LIGHTING, the high temperature paint used on Sparky RU will give off smoke and odour for a
period of time. Open your doors and windows to ensure adequate ventilation! Please follow information
“High Temperature Paint” enclosed in your installation pack on safety and the paint curing process.
Start Up
1. Open the air control to the fully open position by sliding the wire air control knob above the door
hard to the right so that holes are fully open.
2. Open the firebox door. Place crumpled newspaper in the base of the firebox.
Stack kindling around the newspaper like an Indian Tepee and light the newspaper (or firelighters if
using) leaving the door slightly ajar until the kindling is well alight. Then add 2 or 3 small logs of wood
and close the door. Do not adjust the air control.
3. To add larger logs or to refuel always ensure that the air control is on full supply and open the door
slowly. Add logs ensuring air spaces between to allow oxygen for burning and again only readjust the
air controls to the desired setting when the new fuel is well alight and the fire is burning well.
4. It should not be necessary to fill the firebox to capacity. Smaller loads of wood burned on half air
supply will produce more heat per kg of wood. Note: flue length, outside wind conditions and the like
may affect the performance of the fire.
5. Please Note: Over Firing will damage your stove & flue system and will void your warranty.
Please refer to page 6 - Over firing, Causes and Remedies.
Stove Top Cooking
Establish a good fire and allow Sparky RU to heat up. Never cook food directly on the top of the stove.
Always use pots, pans and appropriate cooking implements. A suitable raised trivet on the stove top will
provide slower cooking options. Avoid spills which can be detrimental to the paint finish. If a spill occurs clean
gently using a soft cloth. Avoid scratching or marking the surface. Wear and tear caused overtime can be
touched up with High temperature paint. (See instructions)
Extended Burn Times
Ensure that your Air Control is fully open and that you have a good base of hot embers. Add a good load of
larger pieces of wood. Allow to burn for 10-20 minutes before moving the Air Control to the left to slow.
Sparky RU will burn away for longer periods on low.
At the end of an extended burn move air control right to full air supply. Rake the embers and re-establish
the fire by adding a few small split logs and allow the firebox temperature to build up before adding the
balance of the fuel. The addition of large quantities of cold fuel to a low fire will reduce the firebox
temperature dramatically and this may result in smouldering or ‘losing’ the fire. Proceed with fire as before.

2021
9
MAINTENANCE AND CLEANING
Ensure that Sparky RU is cold and that there are no hot embers in the fire box.
The outside of Sparky RU may be cleaned with a soft dry rag. Sparky RU is coated with high temperature
paint and can be recoated using a spray can of Stove bright high temperature paint. (Refer to touch up
instructions enclosed in your installation pack)
Ash Removal
Over a period of time ash will build up in Sparky RU requiring removal. Ash build up will depend upon the
quality and quantity of fuel used. Always leave a bed of ashes 10-15mm deep in the base of the fire box.
Empty ashes from the fire box into a non-combustible container with a lid using a suitable hearth shovel.
Place container outdoors immediately to a location clear of any combustible materials. Take care as the ash
can retain heat for many days and become a fire hazard. We suggest that you wet the ashes using a garden
hose. When cold the ashes can be used in your garden.
Door Glass
Under normal operating conditions, using well-seasoned fuel, the door glass in Sparky RU should remain
relatively clean. A good, hot fire will burn away most of the black deposits collecting on the door glass during
slower burns. If the glass becomes dirty it can be cleaned by dipping damp paper towels or newspaper into
the dry cold ashes, and rubbing gently on the dirty glass to clean.
If in the unlikely event your door glass breaks it must be replaced with a 5mm robax ceramic glass.
This can be purchased through your Wagener Stoves Dealer.
NOTE: Do not operate Sparky RU with broken door glass and under no circumstance should a non-ceramic
type glass be used as it may explode due to the intense heat inside the fire box.
The Door Seals & Flue Flange
Door seals should be checked and adjusted to provide a perfect seal at all times. The flue must also be fully
sealed where it enters the flue flange. Excess air entering the fire box past a faulty or worn seal will make it
impossible to achieve an extended burn time and may also result in over firing Sparky RU causing damage.
Fire Box Bricks
Fire Bricks serve two purposes. Firstly, to protect the steel chassis and secondly to maintain high
temperatures in the fire box to effect complete combustion of the fuel. Worn and broken bricks should be
replaced. Remember to place your fuel in the firebox rather than throwing it in. This will extend the life of
your bricks and baffles.
Baffle, Brick and Air Bar Fitting & Removal
Ensure Sparky RU is cold. Remove the fire box door for ease of access. (Lift up off hinges and place carefully
to one side) Clear ash away from base of bricks. Remove the “R” pin from each air bar, slide bar to the other
side and remove front and then rear bar. Remove front brick below the firebox opening. Remove side bricks
by sliding forward 30mm and tilting 45 degrees to remove through door opening. Slide rear bricks towards
the sides and angle forward to clear retainer on rear air tower. With the flat of your hand lift up front baffle
and slide it forward until rear edge of the baffle can drop down 90 degrees. Lift the now vertical baffle up and
move it back to clear the locating mounts. Rotate the baffle while in the firebox and remove through door
opening end first and on a diagonal angle. To remove rear baffle again with flat of your hand lift the baffle up
and slide it forward. Once clear of mounting points lower it down into the firebox rotate and remove end
first. To reassemble follow process in reverse. It is essential that baffles are replaced in the correct positions
with no gap at the rear of the firebox and no gap between the front and rear baffle.
Flue Cleaning
Flue cleaning and maintenance is best done by a professional who can also advise you on the condition of your
flue and other parts like bricks, baffles and seals. We suggest this be done at least annually depending on
quality of fuel being used and creosote build-up. However, if you are cleaning the flue yourself first allow the
fire to go out and Sparky RU to cool down. Remove the cowl and rod the flue downwards from the roof.
Remove the baffle to clean out the soot from the firebox. Alternatively remove the baffle and rod the flue
upwards, from inside, through the open firebox door. Return components to correct location and position.
