Convection air
Your appliance uses natural convection. Fresh air enters through the front of the appliance
heater, heats up on contact with the heating element and is exhausted through the air gap at
the top of the appliance. To improve convection, it is advisable to place 2 hot air outlets
outlets and duct them 1m vertically before exiting into the room (for inserts only).
The chimney
The smoke produced by burning wood is evacuated through the chimney flue.
The draught from the chimney generates a negative pressure in the firebox, which evacuates
the smoke and fuels combustion.
smoke and fuels combustion.
- A good draught results from a high temperature difference between the inside of the chimney
and the outside of the house.

- If the draught is too great, the temperature will not be high enough
for good combustion.
- If the draught is too weak, there is a risk of back draught, soiling of the glass and clogging of
the flue.

General recommendations
- It is not advisable to reduce the operation of the fireplace to such an extent that there are no
flames, a sign of poor combustion.

- Certain weather conditions (strong winds, fog) can affect the combustion and draught of the

- When removing the ashes, beware of the persistent presence of embers!
- In the event of a chimney fire, the door must be closed.
- NEVER use liquid flammable products (e.g. methanol) to light or rekindle the fire!
reactivate the fire!
Wood - Choice and use
JIDÉ fireplaces are designed to burn only hardwood logs.
The quality of the wood is important.
Green' wood contains a lot of water (+/- 50%).
Dry' wood, stored for 24 months outdoors, well ventilated and covered, contains 15% water.
Wet wood is harder to burn, offers less heat output and pollutes the environment.

The disadvantages of damp smoke include reduced draught and the formation of tar in the
flue.

Split wood will burn better and improve the operation of your fireplace.

have a high density, will require less heat than 'soft' types.

Overloading your fireplace with wood can have serious consequences, and the following

- Deformation of the baffle
- Bleaching of the glass
- Degradation of the vermiculite
- Increased fan noise
- Excessive expansion of the door, which could cause it to warp
