II your furnace does not keep you
warm blame the fireman and not the
furnace Ninety nine times to one II
In his fault. Firing furnace requires
some knowledge Of the machine and
some understanding of the principles
of air control. Fuel has given guam
tiry of heat units in It always and
there are two exits for heat when 1uel
Is burned in a furnace, one Is up the
chimney and that Is where careless
fireman will send it, the other is into
the house by means OF the radiation
of heat thru the metal, the warming
of air and the flow Of warm air into a
room with an equal flow Of cold air out
Of q room. Most people in this cold
weather think they are saving fuel
when they fire UP six times a day and
leave their drafts on when in fact they
are forcing the maximum amount or
their fuel up the chimney. They should
fill their furnaces as full as they can
pile the fuel into them and then run
a slow fire. Slow burning consumes
the smoke and gases as fuel and the
heat units In the fuel can be used.
Rapid or forced draft burning sends
the smoke up the chimney before 1t
can be burned and used for heating.
And then 80 few people realize that
there is a lifting draft in a chimney.
Chimneys usually pull at the fire
stronger when the wind is blowing
outside and some chimneys nave
stronger drafts than others so that In
stormy weather the heat Is sucked UP
the chimney unless the fireman closes
| the smoke pipe damper or opens the
| check in the smoke pipe 30 as TO breaK
| the draft which pulls at the fire. Over
heated furnaces on stormy nights are
| often caused by strong draft chimneys
| forcing the fire even when front drafts
| are closed. People should always cheek
/ the draft in their smoke pipes ir
| stormy weather. When burning coke
or hard coal a damper which will shut
! off the draft in the smoke pipe Is abb
| solutely essential.
Fuel, too. must not only be full up ir
| the fire box but evenly spread al
around it without being heaped UP OF
coined in the center. wide bed OF no
| fuel gives the most heat.
Let Air Up Thru the Fuel.
1t requires air up thru the fuel t
| make it burn and this means that thu
ashes must always be kept free from
| under the CRATES and the solid clinker'
l
| raked out or else the air can not pas
| up thru the fuel. II the CRATES OF
furnace have heat above and arr
buried in ashes below they will mel
just az the horseshoe melts when tn
blacksmith buries it deep into hot coal'
! and just as the end Of a poker meH'
when thrust deep into the fire. tn
| under side of the CRATES must be cooled
by air or they will get red hot and benz
I down out OF place. Ashes in the mr.
box up nearly to the fuel door do m
| harm IL they are loose SO as to permi
air to pass thru them and II free IRON
clinkers actually aid by holding tn
fire up closer to the top of the furnace
In come furnaces the hot smoke u
| caused to travel roundabout thru ex
ira radiators so as to increase the ares
of heated metal for contact with air
In these furnaces the fireman must D.
sure that his indirect draft damper be
tween the main body of the furnace
and the extra radiator is closed o
else the hot smoke will go directly INT
the chimney without passing thru TN
: radiator and half the heating enicenc!
!. Of the furnace will be lost. only nal
/ Of its radiating surface will be not.

Furnaces can burn fuel withou

wrong with the flow OF air over tn
hot furnace and into the house. n

air should then come up into the room
