HEATING APPARATUS.
AN EXHAUSTIVE REPORT BY ENGINEER
coNOvER or MADISON.

Wisconsin.
GENTLENEs:-As requested BY you
| have made careful examination
and a number of tests of the heating
apparatus furnished BY F Richter q
Sons Of Milwaukee. for your new
Ward school building, for the pur-
pose of determining. first whether the
apparatus complies with the provi-
sions Of the contract and guarantees
under which it was placed. second. to
determine what defects, If any exist.
and the best means for remedying
them
The system Of heating and yentila-
ton adopted by you in making the
contract with Richter & Sons. is in
my judgement. the best one for build
ings of this kind, when carefully and
properly put in. in a good workman
like manner.
Has the apparatus furnished by
them been so put in as provided in
their contract? It is my judgment
that in several respects it has not
They have furnished you boiler. en-
CINE and fan. of sufficient capacity to
do the work required by their contract
They have not furnished and put in
place all the radiation required by
their contract. The radiation fur
nished and put in place has been so
unskillfully placed and Connected up.
and the piping arrangement TO deliver
the air to the different flues of the
various rooms has been designed and
/ placed in so unskillful and unwork-
manlike manner that
First, the amount Of air delivered at
all times to the various rooms varies
greatly. being greater to some rooms
and less to others than required by
the guarantee of the contract
Second, the temperature of the air
/ delivered to some rooms is much
higher than that of the air delivered
to others. 50 that some of the rooms
are under heated while others are
constantly over b red.
In addition to this. the radiation
has been so improperly and unskill-
fully arranged. as to render impossible
any regulation of the temperature by
shutting of portion of the radiation
in mild weather, since if this is at
tempted entirely cold air, or air al
most entirely unheated reaches some
% the rooms
Finally, the arran .ement renders
impossible the tightening of any leak
ing joints without greatly disturbing
and repacking and Tightening a larger
number of joints at the same time.
1t is possible that this last defect
might entirely tie up the apparatus
for so long period of time as to in-
terfere with the use of the school
building, and it has already demon
strated the fact that it may be
great expense, which would be un-
necessary were the radiation arranged
in a skillful and workmanlike manner.
Besides these defect, the method by
which the air from the outside is in
troduced beneath the radiators, tends
to cause additional increase in the
inequality of the distribution on of
air and In that'respect cannot be said
To be arranged in a good and work
manlike manner Besides these inn
portant defects. there are several min
+ or matters requiring change and cor
rection before it can he truly %said
that the apparatus has been furnished
and set up of the best materials and
in good and workmanlike manner
rs provided in the contract. OF these
/ the most important is that the safety
valve is to small, 1t should be at
least / - or better , inches. The
gauge is not a proper one for such
+ work but should be a 5 or inch dial
with 50lbs. as the limit indicated.
i The present guage is intended for
much higher pressuse work and the
changes in pressure are not indicated
! plainly enough for convenience.
1t is absolutely necessary that in
/ each pipe leading 70 ) ilue. there be
a damper with suitable arrangement
for fastening il where placed. 50 that
the cold air delivered to each room
can be maintained approximately
equal. Under the present arrange
ment this is impossible
The arrangement at the fresh air
inlet window is clumsy and incon-
venient one. The exterior az that
window should be protected with a
heavy wire screen. and the doors or
sash whichever are used. should open
inward and be operated by cord
running TO whore the engineer does
his WORK, so arranged that he can tell
at glance how far open the window
is. and closed by heavy counterweight
to prevent the wind blowing it open.
In like manner the return draft door
by which the air is rotated through
the building should be arranged to be
operated from tho same point.

having a sufficiently heavy weight To
