Creating the Cavity
B1 Cavity Shape
The EF5000 is suitable for timber framed cavities.
B2 Designing the Cavity
The following aspects must be considered when designing this installation:
• Appliance physical size
• Wall finishing and interaction with appliance
• Positioning of appliance in regards to wall lining (depth into wall)
• Gas pipe layout
• Gas isolation valve / pressure test point position
• Electrical isolation switch
• Weatherproof location for the 240/24 volt plug pack
The cavity and wall linings may be constructed from standard timber framing materials and do not need
to be non-combustible.
Minimum Cavity Dimensions
Where possible, it is recommended that the cavity is made slightly larger than the dimensions given to
allow the installer the maximum amount of space to work in.
B3 Hearth
A hearth is not required. If one is installed, ensure that it meets the minimum clearances outlined in
B6 “Clearance to Combustibles” on page 8.
The EF5000 is for outdoor use only.
