DIMENSIONS

INSTALLATION

Safety-Clearances shown in below are both for installing with the Rear heat- shield accessory included.
The heatshield is not required only if installing in front of a non combustible or double brick Wall.

The minimum thickness of hearth is minimum equivalent to 9mm thick cement sheeting (ie Bellis board or FC sheeting) for insulation and a top surface with Heat resistance to 600 degrees C.

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: 152mm ( 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 152mm flue must be a tight fit into the heater collar.
The heater must have its own dedicated flue. The active flue must be 6” for the entire length of the flue, and always less than 45 degrees from the vertical.
Replacement room air from outside equivalent in open area to 91cm2 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 2918:2018 )

External Requirements

Refer to AS/NZS 2918:2018

Note: All external air vents & ceiling penetrations must be bird & rodent proofed with permanently fixed screens

Heat shield Instructions For Rear Clearance to Combustible Wall

Note that during assembly, clamping down the top pulls in the side panels, and with castings the gaps between the rear and side panels may vary slightly. This could make the heatshield a slightly tighter fit on one side or the other.

1. At the widest part of the heatshield, it return folds, which are to slot in between the rear Cast panel of the heater and the side Cast Iron panel. bottom folds or tabs, slot between the and the rear panel. See pic.
2. Doing one side at a time, make sure the bottom of this fold is aligned above the top of the Cast Leg, and below the bottom of the Heater cast top. Push the heatshield slightly so it catches in this gap.
3. Then before going any further, align the bottom folded tab so it will insert between the cast leg and the cast back panel. Then tap the heatshield on this side edge so it is slightly inserted into the gap. Don’t push in too far until the other side is inserted.
4. Do the same on the opposite side of the heater, aligning the fold with the gap in the firebody, and then aligning the tab with the gap next to the leg, as per the first side.
5. Once aligned, hit the heatshield with the palm of your hand until it is secured into position. The air gap between the vertical heatshield and the back of the heater should be 25mm (ie not counting the tapered fold at the top).

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 on a daily basis.
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.

Door handle
To open the door, turn the handle upward to the open position, and gently pull.
The door can open up to 100°.
To close, lift the handle up to the open position, close the door, then gently push down on the handle to lock in the closed position (Fig. 3).

Air Control Handle:
It is placed, half-hidden, on the left-hand side just under the door. (Fig.3).
It works by sliding it to the left or to the right. It has two functions:

• Regulates the air for combustion and self-cleaning the glass,
• Open or close the pilot air inlet that helps the first lighting.

Air Supply lever fully open (to the LEFT)
Fully open the air valve when lighting the stove.
This opens the pilot air supply hole, which helps the lighting of the stove, by bellowing a jet of air to the base of the fire, from the front centre of the stove.
When activated, you will notice the bright color of the embers in the center of fire.
At the same time, the air supply to the air wash is open, and oxygen hitting the glass panel will assist in cleaning off soot build up on the glass.

Air Supply lever fully closed (to the RIGHT).
Once the fire is burning along nicely, adjust the air control lever to prevent excessive air intake, which will cause excessive combustion levels and temperatures which can damate the heater.
When the fire is ready to be shut down, turn the valve handle to the right, reducing the air supply. You will notice the variation in the flame pattern and the difference without the the pilot air function.

Once the stove is burning well, set the air controls to fix the desired fire intensity. Somewhere in the middle range is usually the ideal setting, but this will vary by trial and error, depending on the quality of the wood being used and the height and draw of the chimney flue.

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 grill plate located at the bottom of the stove.

Use a tool (brush) to sweep the ash into the ashpan. 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 cover in the bottom of the fire box.

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. 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 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.

HEATERS WITH ENAMEL IN MAJOLICA VERY IMPORTANT! (Applies only to certain models)
In the event of uncontrolled overheating, the different expansion levels of the cast iron, can cause issues with the heater finish, especially with Vitreous enamel components, if applicable, which can cause the enamel to chip.
To avoid this inconvenience, control combustion and never overheat the heater.

INDUSTRIAS HERGÓM S.A. may not be held liable for the deterioration of the stove’s finish, if these instructions are not followed.

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.
The glass in your heater have 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.

MAINTENANCE PRODUCTS

Contact your dealer for a range of products for the preservation of your heater and chimney at your disposal: heat resistant paint, refractory putty, anti-soot products, firelighters, glass cleaning products.

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.
A number of 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.
