"The avoidance of overheating is
one thing of outstanding Importance
in connection with good ventilation"
states the bulletin issued today by
the Minnesota State Medical Asso-
citation.
Because overheating is so univer-
sal and because it is such a menace
to good air too much cannot be said
about the positive control of artifi-
cial heat. A few simple rules will be
given which will help the household
er, in particular, to operate the heat
ing plant for good ventilation.
"When the room temperature is
nearly high enough the heat should
be cut off. This can be done by
turning the radiators off by the hand
valve from the room or by valve
in the furnace or boiler room which
can be operated by hand.
But better than this is a modern
electrically operated thermostat heat
regulator, which controls the heat ac-
cording to the varying outdoor condi-
tions of temperature and wind forces.
Such a system will give the most
satisfactory heat control.
"The thermostat should be set as
low as is consistent with the COM
fort of the room occupants, never
higher than 68 degrees. Usually the
room temperature will vary from
time to time one or two degrees high
er or lower than that for which the
thermostat is set. Invariably the
mistake is made of setting the Their
mostat too high. Some companies
advise 70 degrees. This is too high.
MANY engineers give no heed to
outside temperature. They fire as
heavily on mild days as on cold ones.
The less firing done on mild day the
better. Let the fire smolder without
shaking it down.
"a high fire is economical in run
ming a furnace. Shake the ashes
gently morning and night in ordin
airy weather and in mild weather
once a day or once every other day.
Sometimes once or twice week is
sufficient.
"Never shake the ashes until live
Goals fall through the CRATES, but
stop when you see light glow in the
ash pit. Don't open the ash pit door
for draft, because this forces the
fire too much. A slight opening of
the ash pit draft will raise a gentle
combustion and give moderate
amount of hot vapor to the heating
system, and if the circulation is un-
INSTRUCTED throughout the system
gentle heat will be delivered in all
rooms.
"When enough heat has been Sc
cured the fire should be checked by
tightly closing all drafts at the ash
pit and opening the check damper,
which should be located in the smoke
pipe between the turn damper and
the chimney. This prevents air from
getting to the fire bed and thus
checks the fire.
warm air heat is more flexible
than steam or hot water and conse-
quently more attention to drafts.
The same rules generally should be
followed. Humidity should be added
at the furnace by means of a con-
slant level water pan located above
the combustion chamber, allowing the
steam to be carried to the rooms
through the warm air ducts. 1t is
important to have cold air return re-
gisters from the lower rooms to the
furnace having an area equalling or
exceeding all the delivery registers
combined.
"Where the comfort and health Of
the occupants of homes, schools, Of
flee buildings and other indoor places
depend so much upon heat control
the the responsibility for this serv-
ice should be vested in an intelligent
and responsible individual, who will
study his heating plant and his build
ing in order to secure the best re-
