de?ecting the air across said sets of ‘battles, and means for
the air forced by said blower can be heated by the then
actuated heater.
9. The heating system of claim 3, wherein the second
having a plurality of Walls, a plurality of spaced partitions
preheating zone is provided with a battle means mounted
directing air through said passageways.
12. In a heating system including a hollow cabinet
extending between said walls internally of said cabinet
therein for de?ning a plurality of horizontally disposed 10 de?ning a ?replace and a preheating zone disposed ad
jacent to said ?replace, a ?rst set of baf?es extending
passageways.
10. In a heating system including a hollow cabinet
having a plurality of walls, a plurality of partitions spaced
extending between said walls internally of said cabinet
between said partitions in said preheating zone for de
?ning a plurality of horizontally disposed passageways
in said preheating zone, a second set of intermediate ba?les
de?ning a ?replace and a preheating zone disposed ad 15 extending between said partitions, said intermediate baffles
being arranged parallel to each other and extending angu
jacent to said ?replace, a ?rst set of ba?les extending be
larly upwardly with respect to said ?rst baffles, a third
tween said partitions in said preheating zone ‘for de?ning
set of ba?les mounted above said intermediate baf?es
a plurality of horizontally disposed passageways in said
in parallel relationship therewith, a portion of said third
preheating zone, a second set of intermediate ba?les ex
tending between said partitions, said intermediate ba?les 20 set of baf?es being substantially wider than said ?rst or
being arranged parallel to each other and extending angu_
larly upwardly with respect to said ?rst set of ba?les,
louver means associated with said ?rst and second sets
of baf?es for de?ecting the air across said sets of baffles,
means for directing air through said passageways, said 25
means including a blower mounted on one side of said
?replace and within said cabinet, a heater on the other
side of said ?replace and within said cabinet, and means
for directing air from said passageways through said
30
heater and externally of said cabinet.
11. In a heating system including a hollow cabinet
having a plurality of walls, a plurality of partitions spaced
extending between said walls internally of said cabinet
de?ning a ?replace and a preheating zone disposed ad
jacent to said ?replace, a ?rst set of baf?es extending 35
between said partitions in said preheating zone for de
?ning a plurality of horizontally disposed passageways
in said preheating zone, a second set of intermediate ba?cles
extending between said partitions, said intermediate ba?les
being arranged parallel to each other and extending angu 40
larly upwardly with respect to said ?rst set of bat?es,
a third set of ba?les mounted above said intermediate
second set of ba?les, each of said ba?ies being provided
with a plurality of spaced openings, louver means mounted
