Creating the Cavity
B1 Cavity Shape
The DL850/DL1100 is suitable for both timber framed and masonry cavities.
The cavity shape is dependant on two things:
-The flue configuration (section D1 on page 14)
-The fascia (section B2 on page 8)
B2 Fascia
The cavity shape is dependent on the fascia type. There are three fascia types available with the
DL850 and DL1100:
Bevelled
Inset
Squarred Lite
The Bevelled and Squared Lite fascias sit proud of the finished wall surface and have a simple
cavity shape. The cavity may be constructed from combustible materials.
The Inset fascia sits flush with, or inset from, the finished wall surface and has a more complex
cavity shape. The cavity framing and wall facing for a minimum of 300mm directly above the
Inset fascia must be constructed from non-combustible materials.
Please check the style of fascia before commencing the building of the cavity to the dimensions
shown below. The cavity for Bevelled and Squared Lite fascias may be constructed from
combustible timber framing materials.
NOTE: It is not necessary to line the sides, top, or back of the cavity.
