alternating from the upper to lower set of holes
in draw-up lugs until front section is secured. Be
certain that all sections are drawn up iron to iron
at all three nipple ports.
Jacket Support Brackets must be attached to the
appropriate center section during this process.
Check "Section Arrangement" chart for location
of center section to which jacket support brackets
must be attached (see Figure 8).
Les supports de veste doivent être attachés
à la section centrale appropriée pendant ce
processus. Consultez le tableau «Disposition des
sections» pour connaître l'emplacement de la
section centrale à laquelle les supports de veste
doivent être fixés (voir Figure 8).

LOCATE JACKET INTERMEDIATE
PANEL MOUNTING BRACKETS
NO. 1, NO. 2, AND NO. 3 IN JACKET
CARTON. Brackets are shipped flat and
must be formed by hand, bend as shown
in Figure 10. Brackets are shipped flat and
must be formed by hand, bend as shown in
Figure 10.
ii.
Slide brackets over draw-up rod lugs prior
to inserting the 11″ long tie rods, washers
and nuts. Refer to Figures 11 and 12 for
proper location of each bracket and typical
attachment method.
h. Excess length of draw-up rods must not extend
beyond front and rear section to ensure proper
fit of jacket, adjust accordingly. TIGHTEN ALL
TIE ROD NUTS UNTIL FINGER TIGHT.
THEN TIGHTEN THEM AN ADDITIONAL ½
TURN WITH A WRENCH.
C.
HYDROSTATIC TEST - 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.
1. Tankless Heater Installation
If boiler is ordered with tankless heaters, install
heaters with the gaskets provided. Table V gives
the maximum number of heaters permissible per
assemblage and the heater ratings.
2. Plug all boiler tappings and fill entirely with cold
water.
DO NOT install gauge until after hydrostatic
testing the boiler. Gauge failure may result.
NE PAS installer la jauge avant d'avoir testé
hydrostatique la chaudière. Une défaillance de la
jauge peut en résulter.
3. All completed boilers shall satisfactorily pass the
prescribed hydrostatic test.
a. STEAM BOILERS: The assembled boiler shall
be subjected to a hydrostatic test of not less than
45 psig.
b. HOT WATER BOILERS: The assembled boiler
shall be subjected to a hydrostatic test of not less
than 1½ times the maximum allowable working
pressure, as established by the relief valve
provided with the boiler. For example, a boiler
with a 50 psi relief valve must be subjected to a
test pressure of 75 psig to 85 psig.
Failure to properly hydrotest all boilers at the
correct pressure may result in section assembly
failure in operations.
Le fait de ne pas hydrotester correctement
toutes les chaudières à la pression correcte peut
entraîner une défaillance de l'assemblage de la
section en cours de fonctionnement.
4. 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.
5. After making certain that there are no leaks, drain
boiler and remove plugs for boiler trim and other
connections.
