POINTS TO CONSIDER PRIOR TO INSTALLATION
Location of the Fire. Open Fires are better located at one end of a room or area, as they project the heat away from their opening .
Venting to the Cavity.
This air is to allow the Cavity to Vent the Warm Air. This Warm Air helps keep the Fire and Flue System form getting to Cold . If the Flue and Fire get to Cold the System may soot often and require
cleaning. Each Fire has different ways of venting the cavity .
The Topography of the Land .
The slope and position of the Land in relation to the Home has a bearing on how the wind will interact with the Fire and Flue System. Care needs to be taken to ensure that the Flue Termination is in the
correct position to maximise performance .
The Prevailing Wind.
Care needs to be taken to ensure that the Flue Termination is in the correct position as wind and gusts that hits the Flue and Cowl System may overcome the Cowl and draft back down the Flue into the
Home. This can be a combination of down draft and high pressure.
Hearth and Plinth:
The height of the Hearth off the Floor. The Finishing that is to be used on the hearth is to be allowed for at the design stage.
Positioning of the Flue System:
There is a maximum distance that an Offset Flue can be Installed. Reference to relevant standards.
Flue and Fire Clearance:
To be maintained to the Manufactures Instructions.
Pressure Differential, Venting & External Air into the Building
:
All fires need air to burn and draw correctly, Kitchen Fans, Air Conditioning units, High Wind Zones, Naturally forming Draft spaces, can all have an effect on the pressure difference from inside the
building to the outside. A lower pressure in the building may induce a draft down the flue system and back into the building causing the fire to smoke or spill into the building.
Care needs to be taken at
the design and installation stage to adequately vent the building, or some mechanical system to ensure that there is always a neutral or positive pressure at the fireplace and a negative
pressure at the flue outlet.
This will ensure that the draft in the flue system is always to the outside.
Wind Noise:
You may encounter wind noise in some installations. It is recommended to use an enclosed chase with a chimney pot to help reduce noise. There will always be some noise from the flue systems of all
fireplaces.
