CARE Of FURNACE
IN SUMMER URGED
Home Owner Advised to
Avoid Fire Hazard, Heat
Delays, Rust and SCOT.

naZard, delays III geIClng neaI III Ilie
Fall, rust, dust, SCOT and waste Of
money by caring for his heating ap-
paratus during the Summer, D.
knickerbacker Boyd of the Philadel-
phia Chapter of the American Insti-
tute of Architects, warns in listing
suggestions for putting heating sys-
TENS in safe condition.
Remove the ashes from the fire
box and ash pit and the dust and SCOT
from the top of the furnace Or boiler
and from the pipes and ducts" Mr..
Boyd says. Have all boiler and f1ues
thoroughly cleansed Of any acculnu-
lation Of SCOT, and take down and
clean out heating drums and flue con-
nections of warm-air furnaces.
IF the water has been drained out
Of steam-heating boilers, refill to re-
move sediment. If water remains in
them add fresh water to keep that
apparatus filed up to the safety valve
When starting the fire in the Fall
draw the water down to the proper
level
Lime Prevents Rust.
ITO remove sediment in hot-water
heating boilers, radiators and pipes
refill II the water has been Grained
out. If not, add Sufficien. fresh water
to fill to the proper operating level
"Heaping fresh lump lime in the
fire box from the crate bars up is an
efficient and economical method of
preventing rust from attacking the
metal parts in any type of apparatus
The moisture is drawn into the lime,
which, when it slakes, Is ready for
shaking down through the crate bars
If it slakes before the Summer is over
1t should be renewed. Sometimes
the lime is placed in the ash pit, but
1t Is better to keep it from contact
with a damp floor.
Boilers and furnaces should be left
with all doors wide open so that there
will be a free circulation of air
throughout the internal surfaces The
doors should be oiled at the hinges,
and the face of the doors and frames
should be gone over with an oily rag.
SCOT Should Be Removed.
"Smoke-pipe connections should be
taken down and the SCOT removed.
They should be allowed to stand dis
connected throughout the Summer.
The smoke pipe, when connected to
the 1ue while the heating system is
idle, serves as conductor or runway
for precipitation brought about by
changes of temperature and local
conditions and introduces dampness
into the heater with consequent cor
rosion-deadly enemy of metal.
The smoke pipes should be stored
in as dry place as possible. Before
the pipes are carefully and securely
reset in the Fall the chimney fues
should be examined for accumulated
SCOT. Care must be taken to make
certain that the pipe is connected to
the flue before fires are started.
If the f1ues are but slightly
coated the SCOT may be cleaned out
when the apparatus is started up in
the Fall by sprinkling salt over a
substantial bed of hot fuel. About a
pound at time will be found sutfi-
cient. The hampers should be kept !
open until the fumes disappear. The |
SCOT is disintegrated by the action of |
the salt fumes. Scrap zinc thrown
on hot fire also will remove slight |
coatings of the dangerous chimney |
SCOT. II the due Is badly coated the
SCOT should be expertly removed be-
lore the smoke pipe IS reset.
Innings for Chimneys.
"Chimneys without flue Innings or
In an otherwise dangerous condition
should be properly lined and repaired
before fires are built and the property
jeopardized.
If rooms were cold last Winter a
contractor should be asked What he
can do to correct the situation. Per-
haps locally heated gas or electric
radiators or other appliances should
be installed"
In any event, Mr.. Boyd continues,
the heating system should be ex-
pertly examined now and oyerhauled
New apparatus. radiators and re-
placement parts can be ordered in ad-
vance," he adds Next Fall those
who have put off such work and
crowded the season may have to pay
for the necessary overtime.
Other points to remember are: Re-
glazing broken cellar windows; calk-
ing and Tightening openings in
porches built over cellars or around
window or door frames; weatherstrip-
ping all sashes and doors.
AL 1nf1amable joiSts, beams and
bins in proximity to hues and smoke
pipes should be well insulated. If
present insulation is worn or rusted
1t should be replaced. Metal ash cans
or containers for next seasons use
