Installation & Operation Manual

￿WARNING The boiler is too heavy for a single person to lift. A minimum of two people is needed for

mounting the boiler onto the bracket.

Mounting to a concrete wall:

1.Mount the wall bracket using the two (2) wedge anchor bolts provided with the bracket. To mount the wedge anchor bolts, drill a 1/4" diameter hole 1 1/8" deep and insert anchor. Hang the bracket from the anchor and secure with the two nuts provided. Make sure the top edge of the bracket is away from the wall. Ensure bracket is level when mounted. Extreme care is needed to ensure the bolts are secured in the center of the studs.

Note: If wall thickness does not allow a 1 1/8" deep hole, field supplied hardware suitable for the application should be provided.

2.Hang the boiler on the bracket and secure the bottom of the boiler with two (2) remaining anchors, following the instructions above.

The boiler is too heavy for a single person to ￿ WARNING lift. A minimum of two people is needed for

mounting the boiler onto the bracket.

Mounting to a metal studded wall:

1.The wall mount bracket is designed for a stud spacing of 16 inches from center. For other stud spacing a solid mounting surface must be provided by the installer.

￿WARNING Do not mount the boiler to a hollow wall. Be sure to mount the boiler to the studs only.

2.Mount the wall bracket using two (2) field supplied toggle bolts capable of supporting 100 pounds each. Ensure the top edge of the bracket is away from the wall. Ensure the bracket is level when mounted. Extreme care is needed to ensure the bolts are secured in the center of the studs.

3.Hang the boiler on the bracket and secure the bottom of the boiler with two (2) field supplied toggle bolts.
