Specifications for South African conditions
Thank you for purchasing an INVINCIBLE closed combustion (Slow Combustion)
cast iron multi fuel fireplace. You will find that this unit will use a 1/3 less fuel and be 3 times more effective than an open fireplace. Invincible fireplaces are durable and robust. But like anything in life, it can be abused and misused. The units are designed to perform optimally with a MODERATE fire. OVERFIRING will cause damage to the fireplace and components, this will be evident by glass breaking, baffle plate warping, grate burning away, main structure warping or cracking, discolouration of fireplace top & quick discolouration of stainless steel flues.
THE GUARANTEE WILL BECOME NUL AND VOID IF ANY EVIDENCE OF OVER FIRING OR OTHER MISUSE IS APPARENT OR INSTALLATION WAS COMPLETED INCORRECTLY
Assembly instructions:
- Remove packaging, remove grate and baffle plate
- Tilt fireplace onto its back, fit legs onto 4 bottom corners
- Do not over tighten legs, be careful when tilting onto legs
- Lift fireplace up when moving into position, legs can break
- Fit spigot (round ring)onto top or rear flue exit as required
- Use round flat plate to cover other flue exit
- Use top exit for best draw and fireplace performance
- Position rear of fireplace at least 150mm from the wall
- Fireplace heat output is reduced by approximately 30% when installed into a cavity
- Cavity Requirements: at least 300mm open on either side as well as 250mm at the rear and 450mm above the stove
- Position fireplace well away from furniture and curtains
- Ensure adequate protection for combustible flooring by means of either Armour plate glass, cement plinth or granite slab
- Always fit flues with the crimped end downwards and riveted in place.
- Always use insulated flues in a roof space (fire hazard)
- Ensure cowl is higher than highest point (pitch) of the building, at least 600mm
- Always ensure flues go up to the cowl inside a chimney cavity
Fitting the baffle plate: (if loose baffle plate is supplied)
- Place baffle plate with 2 flanges on top of the rear firebrick
- Find 2 “lugs” on left & right hand side panels inside the fireplace’
- Position 2 flanges on short sides of baffle plate onto side lugs
- Baffle plate will lie 45˚ up from firebrick towards top front
Operating the fireplace
WHEN REFERING TO MULTI FUEL, IT MEANS MAINLY WOOD WITH SMALL AMOUNTS OF ANTRACITE
- To cure the iron components, start with 3 moderate fires ( ½ hour, ¾ hour, 1 hour)
- Initially fireplace may give off a pungent smell and some fumes
- With use, hot spots will appear on the fireplace (grey spots)
- Start the fire by using a decent amount of “very dry” kindling
- Leave all vents open when lighting the fire (you need ample oxygen when air is cold and no wind outside)
- (smoke may be experienced when lighting up the fireplace)
- Add larger pieces of dry wood (2-3 pieces approximately 40-50mm in diameter)
- When fire is “roaring”, add not more than one or two pieces of dry wood
- Close the door and adjust bottom vents for required burning rate
- Add only a few pieces of anthracite at a time ( 5 to 6 large nuggets), only when a wood fire is well established (cast iron units ONLY)
- Always use more wood if alternate fuels are added to a wood fire
Recommended fuels
- Fireplaces work the best with large pieces of dry, well-seasoned wood
- Buy a load of dry seasoned wood before start of the rainy season (end of August)
- Do not use Pine, wet or chemically treated wood
- Do not use gasoline, kerosene or newspaper to start the fire
- Use anthracite only with a well-established fire
- Large amounts anthracite will cause over firing or block grate
Operating tips and maintenance
- Always leave top vents open if fitted to particular model
- Carbon build-up will occur on inside of door glass (Wet wood will aggravate deposit)
- Clean glass: wipe with damp cloth dipped in wood ash when cold
- To restore luster look of fireplace, use stove polish (available from The Fireplace Company)
- Do not use detergents or polish of any kind on the fireplace or Glass (please enquire about recommended products available at our showroom)
- Have your unit serviced at least once every two years, by one of our approved service agents to maintain your 10 year warranty

Useful info:
I want to see the flames
Most closed-system fireplaces are fitted with fire-resistant glass doors, which allow you to enjoy the sight of the flames. Modern designs have even larger glass doors than ever. An air-wash cleaning system ensures that the glass does not carbon up easily.
I like the idea of a wood-burning fireplace, but I don’t want the smell and soot in my house
Closed system fireplaces are generally manufactured from cast iron, which retains its shape through years of heating and cooling.
This means that the joints and doors always remain tight. Rope gasket seals are used to prevent smoke and soot from escaping into the room.
I’m put off by the thought of cleaning a fireplace
Because closed-system fireplaces are so fuel efficient, very little ash or residue is left over
from the wood. Cleaning is only required after the fireplace has been used several times, i.e. once or twice a week.
Fireplace Safety
Although the outside of a closed-system fireplace is very hot, the potential for accidents is much smaller than with an open fire. Small children soon learn to stay away from the fireplace and enjoy the heat.
Simple and Safe Installation
Closed-combustion stoves generally provide a flue outlet on the top or on the back of the unit, with some models offering both. If you have an existing fireplace and chimney, the new stove can be placed in the fireplace, or in front of it with the flue feeding into the chimney, but special care needs to be taken to ensure a proper draw up the chimney and enough air flow around the unit.
It is important that any fireplace be installed professionally.
