Remove boiler from wood pallet

Figure 1-3Boiler Removed from Shipping Pallet

 

1.After removing the outer shipping crate and plastic from the boiler, remove the parts package (packaged parts inside the controls compartment of the boiler inside the lower front access panel).

2.To remove the boiler from the pallet:

a.Remove the three (3) shipping bolts located inside the controls compartment securing the boiler to the front of the pallet (see FIG. 1-2).

b.Remove the three (3) shipping bolts that fasten the tie-down brackets securing the legs to the rear of the pallet (FIG. 1-2).

c.The boiler can now be removed from the pallet using a lift truck lifting from the front or rear of the boiler. If lifting from the front, the lift truck forks must extend at least half way under the boiler heat exchanger to assure proper lifting technique with no damage to the boiler.

￿WARNING Failure to assure the truck forks are long enough to extend at least halfway

under the boiler heat exchanger will result in the boiler tipping off the lift truck, and potentially falling. This will result in severe personal injury, death, or substantial property damage.

d.If lifting by crane is desired, remove the top access panels to gain access to the lifting lugs located on the boiler (see FIG. 1-3). It is also recommended that the upper and lower front panels along with both front side panels be removed (no tools required).

Do not drop the boiler or bump the jacket NOTICE on the floor or pallet. Damage to the

boiler can result.

Maintain minimum specified clearances for adequate operation. All installations must allow sufficient space for servicing the vent connections, water pipe connections, piping and other auxiliary equipment, as well as the appliance. The clearance labels on each appliance note the same service and combustible clearance requirements as shown in this manual.

Multiple boilers may be installed side by side with no clearance between adjacent boilers because this boiler is approved for zero clearance from combustible surfaces; however, service access will be limited from the sides.

Consult the Venting section of this manual for specific installation instructions for the appropriate type of venting system that you will be using.
