OUTSIDE AIR CONNECTION
•When installing the stove using the outside air connection, we recommend that the installation is
performed by qualified personnel.
•Always keep in mind that air is entering the stove through the connector. This air inlet can never
be blocked. Ensure that the pipe connecting the stove to the outside cannot be crushed and that the
entrance to the pipe cannot be blocked on the outside. It is necessary to cover the inlet with a protective
vermin proof grill.
•The location of the outside air inlet of air must be protected from the wind to avoid a possible
positive or negative pressure from affecting the combustion of the stove.
•The diameter of the ducting pipe to supply outside air is 80mm.

Flue Installation
The Flue type required: 150mm (6”) active flue and a solid 8” heat shield within the room, and air cooled
Double casing insulation (triple skin) from above the ceiling, as per AS2918:2018 default flue kit. See
diagrams below for flue requirements. The Active stainless-steel flue must be a tight fit into the heater
collar. For the reduced rear clearances, it requires a deflector shield between the 6” Active and the 8’
solid heat shield for the first length of flue.
The heater must have its own dedicated flue. The active flue must be 150mm / 6” for the entire length
of the flue, and always less than 45 degrees from the vertical.
Replacement room air from outside equivalent to 160cm2 must be supplied into the room.
Flue Outlet Positions
Minimum Flue Height as per AS/NZS 2918:2018
NOTE: Flue exit MUST also be as high as any nearby structure within a 6m Radius. (AS/NZS 2918:2018)

5 - Heat Shield Instructions For Rear Clearance to Combustible Wall
Note that the heater will either come with the heatshield fitted, or will need to be fitted as per the manual
supplied with the heat shield.
The Heatshield is fitted to the heater by using 3 of the upper existing screws in the rear of the heater, the ones
that align with the heatshield. The shield will sit up slightly to cover the flue collar.

Insert Stainless Steel baffle deflector plate.
This is supplied wiith your heater and should be inserted by pushing it onto the upper baffle to reduce
the draft of the flue and keep the heat into the firebox, improving the efficiency of the unit. Shown as
part “A53” in exploded diagram.
7 - USING THE STOVE
Once your stove has been installed and connected to the chimney, you are ready to light the fire.
Although your stove is easy to use, the combustion process of solid fuels is complicated, as it involves
several factors, and it takes time and experience to understand the process.
Before lighting your stove for the first time, please take time to become familiar with the different control
systems and parts of the unit, how to choose the right wood, how to light it quickly and use it daily.
ALWAYS KEEP IN MIND that the stove generates heat and, therefore, keep children, clothing, furniture...
at a distance to prevent burns from direct contact with the appliance.
Below, we have included some advice on your stove and on its use. Please read with care.
For the first initial firing of the heater, use a small kindling fire and some medium sized pieces to heat up
the heater and then let it die down, to cure and harden the paint, ensure the room is well ventilated
during this process.
Door handle
To open the door, pull on the handle on the bottom right of the door, by gently pulling horizontally.
The door can open up to 95°. When the fire is warm you must use a heat proof glove.
To close, using the handle gently push the door to the closed position.Ensure by pushing on the door
that it is fully shut. Do not slam the door shut and don’t let the door bounce, it won’t be fully shut (Fig.
3).

12
Air Control Handle:
These are located below the door on the left hand side (Fig.3).
When lighting the heater have the control pushed all the way to the right. Once the fire is alight and a
good ash bed has been built up, adjust the valve to the left to prevent excessive air intake, which will
cause excessive combustion levels and temperatures.
An intermediate position is usually the ideal setting, depending on the quality of the draw of the chimney
installed and on the type of fuel being used (hard wood) (Fig. 3).
Ash pan - Very important!
Only handle the ash pan when the stove is cold.
Always avoid opening the ash-pan if your stove is in operation.
To clean the ash, lift the solid base plate located at the bottom of the stove.
Use a brush and shovel to sweep the ash into the ash pan. Remove the ash-pan from the front (Fig. 4).
To remove the ash-pan from its position, pull the handle gently to release it. Once you have emptied the
ashes, return the ash pan to the ash drawer, pushing it into place to create a seal.
Do not forget to replace the solid cover in the bottom of the fire box.
The heater can only be run with the Ash pan in position, and pushed back sealing the ashpan and the
opening with the insulating tape included.

13
8 - LIGHTING THE FIRE
Important Note:When first lighting the fire there may be some moisture in the stove, produced by the
humidity of the environment where the stove was stored.
It is very important that the first time the heater is lit, it is done so slowly.
This is for the following reasons:
•Stabilise cast iron parts.
•Harden the joint sealant putty.
•Prevent cracking of the vermiculite bricks due to moisture.
Advice:
•We recommend that the first loads of fuel be small.
•To generate draw, heat the chimney by introducing some burning paper in the gap between the
front and the deflector, directing it toward the chimney.
•While lighting for the first time, ensure the room where the heater is located is well ventilated as
the paint work may let off some fumes as the paint cures
•Keep the stove on for a few hours at this intensity.
•IMPORTANT! The total height of the fire load should not exceed 50% of the height of the
combustion chamber.
•The heater must be closed at all times during combustion to prevent smoke from leaking out.
Only open the door to add fuel.
Daily use:
After lighting up for the first time, your heater will be ready for daily use.
Your heat requirements will be obtained based on the frequency and the amount of firewood you load.
When your heater is cold, we recommend lighting it up slowly.
Overheating:
Overheating means that you have operated your heater at an excessively high temperature for a long
period of time. This can damage your appliance and, therefore, it is a situation that must be avoided.
Overheating is the result of excessive draw, due to any of the following reasons:
•The Primary Air Control is excessively open for the type of wood being used.
•The chimney is too tall.
•Improper maintenance of the stove, which may result in air infiltration.
•Inappropriate fuel that produces high temperatures.
•Door not closed correctly.
ATTENTION!
During the operation of the stove, the ash pan cover must be perfectly positioned to seal the fire box.
Any uncontrolled intake of air produces overheating that can damage the stove.

9 - CLEANING & MAINTENANCE
Your heater is a device that is subjected to extreme temperatures and to the corrosive effects of
combustion residual materials. Regular maintenance is essential for a longer life and improved user
experience. We recommend performing the following inspections frequently:
DURING THE SEASON
•Perform a visual inspection of the chimney. Clean soot and tar if they have begun to accumulate
on the inner walls of the heater.
•Check whether the doors close tightly; adjust if necessary.
AT THE END OF THE SEASON
•Inspect and clean the chimney.
•Use the vacuum cleaner to clean inside the heater and inspect it.
•Any soot and tar (creosote) that has accumulated on the walls of the heater will hinder
performance.
•Inspect door seals. These should be replaced when they no longer seal the door perfectly.
•In the case of painted heaters, paint the cast iron parts again if necessary.
CLEANING
Cleaning should always be performed when the heater is cold.
Cleaning ash.
These heaters are equipped with an ash pan located at the bottom of the heater.
Remove the ash pan and remove the ash.
Ash should be emptied into a metal container and immediately removed from the house.
If necessary, clean the ash pan housing.
Enameled parts. (Applies only to certain models)
Preferably use a damp cloth.
Do not used strong or abrasives detergents that might damage the surface.
Painted parts.
Clean with a dry cloth to avoid rust.
Chimney and connecting unit.
Ensure the flue is installed by a qualified plumber, and have the flue cleaned regularly every 12 months if
possible.
DOOR PANELS
Cleaning
Fireplace window cleaning liquids are quite effective products.
Never try to clean the glass while the fireplace is working.
We recommend using wood heater fire window cleaning products for their proven efficacy.
If the glass on the fireplace door is constantly covered in soot, this means your fire is “poor” and that the
connecting pipe and chimney are being blocked by soot and creosote or burning green or wet wood.
Replacing Glass -
The glass in your heater has been especially manufactured for log stoves.
If they should break, they must be replaced by another glass panel with the same technical specifications.
Contact our Distributor to provide you with the appropriate glass, together with instructions to assemble
and seal.

10 - SAFETY
WARNING!
Gas/log/pellet units get hot when in use.
Consequently, owners must act with precaution and keep at a distance. Especially keep children, the
elderly and other people who require special supervision, as well as pets, away from the fireplace when
it is in use.
Make sure that children or other people who are not familiar with how the device works are supervised
by responsible people when they are near the fireplace.
In order to prevent burns or children or other people from coming near the appliance, use a fire grille
or screen.
Several possible risks are present when operating your solid fuel oven with fuel of any brand. The said
risks can be minimized if the instructions and recommendations included in this manual are followed.
•When installing the stove, observe the necessary safety distances for the oven and chimney from
combustible surfaces (wooden or papered walls, wooden floors...). Safety distances must be respected
when the lining on walls or nearby areas may be damaged or deformed by temperature (varnish, paint,
PVC...). Fig. 6
•The base where you are going to install your heater must be flat and provide a perfect seat. The
said base must also be capable of supporting the weight of the heater. The base must be built using heat
resistant materials.
•All the area around the heater must be heat resistant. If not, they must be protected by fire-proof
material.
•Ash should be emptied into a metal container and immediately removed from the house.
•Do not use flammable liquids to light the stove. Keep any type of flammable liquid (petrol, gasoline,
alcohol,.) at a distance from the fireplace.
•Never use coal or fuels that are not recommended for the operation of this product.
•Periodically inspect the chimney and clean whenever necessary. Also inspect the state of joints,
glass, screws...
•Protect your hands with a glove or other insulating material because, during operation, the
opening and closing handle will be hot.
