HYDROSTATIC TEST, see Fig. 9: After the boiler
sections have been assembled, it is essential that the
boiler be hydrostatically tested before the canopy, flue
cover plates, jacket, or piping is installed.
a. Plug all boiler tappings and fill boiler completely
with cold water.
DO NOT install gauge until after hydrostatic
testing the boiler. Gauge failure may result.
b. All completed boilers must satisfactorily pass the
prescribed hydrostatic test.
(1) STEAM BOILERS: The assembled boiler must
be subjected to a hydrostatic test of 45 psig to 55
psig.

TesTinG boiler assembly for leaks
(2) HOT WATER BOILERS: The assembled boiler
must be subjected to a hydrostatic test of 75 psig
to 85 psig.
Failure to properly hydrotest all boilers at the
correct pressure may result in section assembly
failure in operation.

EXAMINE BOILER CAREFULLY, INSIDE AND
OUTSIDE, to insure against leaks from cocked nipples
or through concealed breakage caused in shipping and
handling. This precaution is for your protection and
will simplify handling of necessary replacements and
adjustment claims. After making certain that there are
no leaks, drain boiler and remove plugs for boiler trim
and other connections.

nuts.
b. Secure opposite end section to high base end panel
with 3/8"-16 x 2" Cap Screws, washers and nuts.
c. Apply Furnace Cement to gaps between section
