LOCATION
Water Tube Combination Boiler, Star, No. 1/C6056, 2/C6057,
3/C6058.
Inspected internally and externally.
The low water fuel cut-outs on each boiler are wired to include a
manual switch, which if closed renders the particular low water
device inoperative. This is done because each control can shut
off all boilers. In the event only one boiler is used, then the
hand switches of the controls on the other two boilers must be off.
The wiring sh uld be re -arranged so tht the manual switch does not
override the control under any conditions.
These three controls, ana this is particularly true with the ones
on the Nos. 1 and 3 boilers afe old. One of the controls was opened
and found badly corroded, and practically inoperative. The float
bowl was full of sludge. To place these controls in a satisfactory
and safe condition, it is recommended that the heads of each control
be replaced with a new or factory rebuilt head.
The wiring to the low water fuel cut-out devices was found to be
unsatisfactory for this applic-tion.
WE recommend the substitution of No. 14AWB 1050 C machine tool wire.
This wire will meet UL Requirements and is available at all supply
houses selling Underwriters approved wiring.
The low water column connection sh: :uld be provided with a drain
pipe and valve of not less than 3/4" pipe size to flush out any
sediment that may collect in the pipe and to permit testing.
The conditions outlined were discussed with Mr. Watson, Superintendent
of Buildings and Grounds, at the time of inspection and we understand

they will receive proper attention.
Air Tank No. 1, 1'x5' .
Inspected externally while in service.
As this object is not protected against excess pressure, it should
be provided with a 1/4" A.S.M.E. standard safety valve adjusted to
relieve at 40 lb. There should be no intervening shut-off valve
between the safety valve and object.
The condition outlined was discussed with Mr. Watson, Superintendent
of Buildings and Grounds, at the time of inspection and we understand
it will receive proper attention.
