Experts Make Sure That Heat

to Do Good Job
SIZE is ESSENTIAL

Construction and installation of
furnaces no longer are done by
guesswork, according to George
Ebert, furnace expert for the French
and WEIGH Hardware company, who
installed the Mueller full-front fur
mace in the Demonstration Home.
Cuesswork methods have gone in
TO discard. Ebert said, and the fur
mace dealer who employs them Is
certain to run into trouble and pos
sibly impair his reputation.
When the modern furnace expert
sells furnace he wants to know,
first of all, that it will be satisfac-
tory. Otherwise he had better not
sell it. The furnace must be large
enough to do the job which will be
required of it and still there is no
sense in making it too large.
After furnace men fought with
these problems long enough they de-
vised standard code for dctermin-
ing the size of furnace necessary. 1t
takes into consideration the capacity
of the furnace, the size Of the house
and the number of doors and win
dows. Because heat always escapes
through doors and windows it is nee
pssary to take their size and num-
bers into consideration in planning
the heating system. The furnace IN
the Demonstration Home is big
enough to give good results and not
too big for economy.
Need Good Chimney
One Of the major considerations in
a satisfactory furnace installation,
Ebert said is the chimney. The best
furnace will not give satisfaction un-
less there is sufficient draft to sup
port proper combustion. The CHM
ney draws air through the fire, caus-
inl, the coal to burn and unless the
coal burns there is no heat. 1t is
easier to control thu draft by proper
devices than to provide draft where
the chimn ~ is clogged, of poor de-
sign or of insufficient size.
The Mueller furnace in the DEM
onstration Home is especially de-
signed to burn Ignite coal. It has a
circular CRATE which prevents the
ashes from clogging the sides Of the
tirebox and thus reducing the heat
ing value and causing trouble with
the fire. Standard CRATES also may
be had.
Crate Shaking Easy
Free-acting rollers make shaking
the CRATE an easy matter and the
CRATE is SO designed that it may be
pulled out through the firebox door
without the use Of tools. The ashpit
door and opening and the fire door
and opening are surface ground to
insure a smoke tight fit and all cast
ings fit together in deep joints to
prevent leakage Of smoke or gas.
These joints are sealed as an addi-
tional precaution.
The furnace is designed for life
time Of trouble-free service. Its
castings are made of special steel
and iron to eliminate warping which
often causes a furnace to give
trouble. The warping is caused, I'M
less the castings are made OF proper
materials, by the alternate expan-
sion and contraction of the metal as
the furnace grows hot or cold.
A humidifying device insures
proper moisture content for the air
in the house at all times. 1t is con-
nected with the house water system
and works automatically. Many
cases of sickness may be traced to
poor heating and to lack Of moisture
in the air. Since this humidifier is
automatic it eliminates the factor
Of forgetfulness by the householder.
