CHAPTER 4:
UNIT PREPARATION
4.1 HANDLING INSTRUCTIONS
The Esteem 399 Low NOx boiler is generally easier to handle and maneuver once removed
from the shipping carton. To remove the shipping carton, follow these instructions:
Removing the Esteem Boiler from the Shipping Carton
CAUTION!
Use care not to lift the unit from, or place the unit on the front
plastic control panel, damage can occur. Use care not to drop,
bump or rotate the boiler upside down, as damage to the boiler
will result.
1. Remove any shipping straps and open the side of the shipping carton.
2. Slide the unit with the foam inserts out of the carton.
3. Discard all packing materials.
4.2 WALL MOUNTING INSTALLATION
The Esteem boiler should be wall mounted using the bracket provided with the boiler. The
Esteem boiler is not designed for floor installation. If floor installation is required an optional floor
stand is available through AERCO International.
WARNING!
The wall used for mounting the Esteem 399 unit must be vertically
plumbed and capable of supporting a minimum 250 pounds [115
kg]. Failure to comply with these requirements could result in
personal injury, death or substantial property damage.
4.3 WALL MOUNTING GUIDELINES
•
The boiler is heavy and bulky. A minimum of 2 people is required for mounting the boiler.
•
DO NOT mount or attempt to mount the wall bracket to hollow sheet rock or lath walls
using anchors. Only install boiler to studs or equivalent wood structure.
•
The wall-mounting bracket is designed for stud spacing of 12 inch or 16 inch on center.
For unconventional stud spacing, a solid / secure mounting surface must be provided for
installation of the bracket.
•
For mounting on wood studs, install the bracket using the lag screws provided with the
boiler. Ensure both lag screws are installed securely in the studs.
•
For mounting on metal studs, install the bracket to the studs using 3/16” toggle bolts and
washers.
•
For mounting on solid walls (rock, concrete, brick, cinder block, etc.), install the wall bracket
using anchors (double expansion shields) and bolts with washers provided with the boiler.
