Set Packaged Boiler or Block Assembly in Place
2a
For packaged boiler:
1. Remove top jacket panel. Set aside until after
boiler is piped.
2. Remove lag screws (2 in front, 2 in rear) from
shipping rails.
3. Remove boiler from skid. Cables are already
attached to block assembly. See Lifting Weight
Chart.
• Using crane - hook middle of each cable to
eye of crane.
• Using hoist - hook middle of each cable to
hoist. Raise boiler off skid. Use pipe rollers
under skid angles to roll boiler.
4. Place boiler in final position. Center boiler on
foundation, if used.
5. Level boiler. Shim under skid angles, if
necessary.
6. Cut off cables.
Cables are not intended for long-term usage.
Cables may corrode inside boiler, weakening their
lifting strength. Failure to remove cables can
result in severe personal injury, death or
substantial property damage.
7. Proceed to “4a: Perform Hydrostatic Pressure
Test,” page 12.
For block assembly:
1. Remove lag screws (2 in front, 2 in rear) from
shipping rails.
2. Remove boiler from skid. Cables are already
attached to block assembly. See Lifting Weight
Chart.
• Using crane - attach free end of cables to eye
of crane.
• Using hoist - attach free end of cables to
hoist. Raise boiler off skid. Use pipe rollers
under steel skid angles to roll boiler.
3. Place boiler in final position. Center boiler on
foundation, if used.
4. Level boiler. Shim under skid angles, if
necessary.
5. Cut off cables.
Cables are not intended for long-
term usage. Cables may corrode
inside boiler, weakening their
lifting strength. Failure to
remove cables can result in
severe personal injury, death or
substantial property damage.
6. Inspect block assembly for disjointed sections.
Check gas-tight seal of flue collector hood, flue
collar and cleanout plates.
Gas tight seal must be
maintained to prevent possible
flue gas leakage and carbon
monoxide emissions, resulting
in severe personal injury or
death.
a. Open damper in flue collar.
b. Check inside section assembly for any light
passing through unsealed areas.
c. Mark all unsealed areas.
d. At unsealed areas, check for damaged
gaskets, sealing rope not in place, loose bolts
or nuts, or missing holddown clips. Correct
all conditions and repeat step b. If unsealed
areas still exist, contact your Weil-McLain
distributor or sales office before continuing
installation.
7. Proceed to “4a: Perform Hydrostatic Pressure
Test,” page 12.
