Heat Circulating Fireplace
Installation Instructions
IMPORTANT:
The air from the hot air outlet is just as hot (if not hotter) as the heat produced inside the firebox. For that
reason, the combustible clearances for the hot air outlet is the same as the clearances from the fireplace opening. Ducting
the hot air directly from the outlet through any combustible materials is not recommended.
Electric Fans:
Fans are optional. The Fire Magic circulator will naturally begin to circulate hot air once the air in the heating chamber
heats up. Fans will start the air to circulate immediately, and will provide a more forceful air flow.
When fans are used, they must be used in pairs, one in each cool air inlet.
Do not
locate in hot air outlets. The fans
should be pulling air from the room and pushing it into the air inlet. Both fans should be wired to run simultaneously.
Fire Magic fan sets are available for two sizes of air inlets, 8 x 10 and 8 x 14. These sets include air grills with fans
mounted on the frames and a wall-mount fan control switch.
Masonry Face (front):
The construction of the fireplace face is much the same as laying the face of any other fireplace. The finished masonry
opening should be at least 1” less than the circulating fireplace opening to conceal the joint between the masonry and
metal. This joint should be packed with insulation. Remember to allow for the openings for the air inlets and outlets.
Chimney and Flue:
Chimney and flue construction is the same as any other
fireplace. Either a masonry or a metal chimney may be
used with a Fire Magic circulator. It is important to note
the flue, whether masonry or metal, must be supported by
masonry and
not
the metal unit. The drawing on the right
depicts the correct way to set the flue liner. When using a
metal flue, the transition from the masonry to metal is done
above flue liner.
A flue of sufficient size should be used with each fireplace
unit. The standard formulas for determining flue size apply
to Fire Magic circulators. The table below gives fireplace
opening areas, and minimum flue areas from the IBC
section 2113.16.1 and the IRC section R1003.15.1 to
assist in selecting the proper flue size.
Fire Magic circulators may be use in multi-level fireplaces,
combined in a single chimney (not a single flue). The
standard rules that govern multi-level fireplaces and
concerning flue offsets and heights apply.
