8.9 Heat Shield for Combustible Shelf
It is possible to reduce the minimum height required between the floor and a combustible shelf
by installing an optional heat shield.
Different shelf sizes are listed in the following table.
POSITIONING AND DEPTH
OF THE SHELF
B C
50" (1,27 m) 6" (152 mm)
52" (1,32 m) 8" (203 mm)
54" (1,37 m) 10" (254 mm)
56" (1,42 m) 12" (305 mm)
8.10 Non-combustible Shelf Installation
It is possible to install a non-combustible shelf above the fireplace. It must be installed at least
48" (1,22 m) from the base of the fireplace, regardless of the depth of the shelf.
The shelf will be hot. Do not put combustible materials on the shelf.
9. The Venting System
The venting system, acts as the engine that drives the wood-heating system. Even the best
fireplace will not function safely and efficiently as intended if it is not connected to a suitable
chimney. The heat in the flue gases that pass from the fireplace into the chimney is not waste
heat. This heat is what the chimney uses to make the draft that draws in combustion air, keeps
smoke inside the fireplace and safely vents exhaust to outside. Heat in the flue gas can be seen
as the fuel the chimney uses to make draft.
9.1 Location
The location of the chimney is crucial for the proper functioning of the appliance. The chimney should
be installed within the house rather than up an outside wall and should rise straight up through
the tallest part of the house. This installation benefits from being enclosed within the warm
house environment, produce stronger draft, accumulate fewer creosote deposits and will be
unaffected by cold temperatures or harsh winds.
Outside chimneys will lead to cold back drafting when there is no fire in the fireplace, slow
kindling of new fires, and smoke roll-out when the door is open for loading.
