Set boiler in place
Do not raise or move assembled sections
using a jack or forklift. This could cause
the sections to shift, resulting in leaks.

Ensure the equipment and cables used for lifting are
designed to handle the load. See Figure 5 for approximate
weights of model 94 section assemblies. Failure to comply
can result in severe personal injury, death or substantial
property damage.
The boiler contains ceramic fiber and fiberglass materials.
Use care when handling these materials per instructions
on "Handling ceramic fiber and fiberglass materials,"
page 36 of this manual. Failure to comply could result
in severe personal injury.
For packaged boiler or assembled block
assembly:
1. Packaged boilers only — Remove top jacket panels. Set aside until
after boiler is piped.
2. Remove lag screws from shipping rails.
3. Remove boiler from skid. Cables are already attached to block as-
sembly. See Figure 5 for lifting weight.
• 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.
4. Place ¼" x 3" steel plates on floor or foundation, spaced 51 inches
apart, as shown in Figure 1, page 4.
5. Place boiler in final position. Place boiler on foundation (if used)
as shown in Figure 1, page 4.
6. Level boiler. Shim under legs if necessary.
7. 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.
8. Inspect block assembly for disjointed sections.
a. Check inside section assembly for any light passing through
unsealed areas.
b. Mark all unsealed areas.
c. At unsealed areas, check for:
• Damaged gaskets.
• Sealing rope not in place.
• Loose bolts or nuts.
d. Correct all conditions and repeat step b. If unsealed areas still
exist, contact your Weil-McLain distributor or sales office
before continuing installation.
9. Check gas-tight seal of flue collector hood 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.
10. Proceed to "Perform hydrostatic pressure test," page 11.
