11.
Introduce tie-rods into their seats, placing them as illustrated. The short tie rods are to be installed
in the lower positions with the short threaded part towards the front of the boiler. The tie rods in the
rear of the boiler will need to be cut so as not to extend more than 2-1/2 inches past the nut so as not
to interfere with the jacket installation.
12.
Install washers and nuts onto tie-rods from the rear. Clamp the boiler body together, checking and
maintaining tie-rod extensions equal. Additional nuts are to be placed on the tie rods for jacket
assembly
13.
Install lower plug bushing and upper bushing with 1/2” NPT threads using the gaskets provided.
14.
Install supply and return flanges using the 12mm x 68mm studs with the shorter tread length into the
threaded openings in the casting. Tighten with nuts, washers and gaskets provided.
15.
Insert a light into the combustion chamber to check for proper sealant between the sections. If light
is visible force sealant with a putty knife from the exterior between the sections.
Boilers which were split or field assembled will need to be hydrostatic pressure tested in accordance with
Section IV of the ASME Boiler and Pressure Code at a pressure equal to 1-1/2 times the maximum
allowable pressure on the boiler nameplate.
Burner Door Assembly
1.
Select the direction for the burner door and place the hinges on the appropriate side.
2.
Lubricate the threaded stems of the hinges and tighten them into the front section to the dimension
indicated. Then lock into position with the nut provided.
3.
Place a brass hinge nut on each hinge with the extension facing the door.
4.
Place the door over the hinge and use an additional brass hinge nut to lock the door into position
5.
Install the 12mm x 118mm studs with the shorter tread length into the threaded openings in the front
casting.
Warning:
Do not leave boiler unattended during hydrostatic testing. Cold water fill could
expand as it warms causing excessive pressure, resulting in severe injury, death or substantial
property damage. Leaks, if found, must be repaired immediately. Failure to do so can damage
boiler, resulting in substantial property damage.
Caution:
Do not hydrostatically test the boiler with any controls installed. Damage to
controls can occur due to over pressure.
