NTI INSTALLATION MANUALS

Part 3 - Prepare the Boiler for Installation

This boiler is too heavy for one person to lift. It is highly recommended to install the boiler with two people. Use caution as to not drop the boiler, which could damage the boiler and cause property damage and/or severe personal injury. Verify that the boiler is properly and securely mounted before leaving unsupervised. Failure to comply with the above and properly mount the boiler could result in substantial property damage, severe personal injury, or death. 1. Position the upper wall mounting bracket on the concrete wall. Ensure the bracket is level. Then use the bracket as a template to mark four (4) drilling holes on the wall - two (2) on each side of the bracket. See Figure 4 for details. 2. Drill and plug the wall. Then secure the upper mounting bracket using the provided Fischer S 10x50screws. Ensure the bracket is level. 3. Install the lower mounting bracket on the boiler. Then hang the boiler on the upper mounting bracket. Ensure the boiler is level. Then use the lower bracket to mark the lower bracket drilling holes. 4. Drill and plug the wall and secure the lower mounting bracket using eld provided screws. Then adjust the lower mounting bracket on the boiler. Ensure the boiler is installed plumb. Tighten the bracket to the boiler. 1. Mounting to a Concrete Wall D. Wall Mounting Considerations These boilers are wall mounted. Use only the wall mounting instructions included with this boiler. Ensure the wall that the boiler is intended to be mounted on is comprised of cement, brick, block, or wooden studs spaced 16” apart from center. Ensure the wall is capable of supporting at least 150 lbs (68 kgs). If ooding is possible, elevate the boiler to prevent oodwater from reaching the boiler. Ensure the boiler is installed in a location that minimizes the risk of water damage due to leaking valves, pumps, unions, etc. The boiler may be installed on any suitable internal wall (suitable sound proo ng may be required when installing onto a stud partition wall). Ensure that the structure of the installation location is sufÀcient to support the full installed weight of the boiler, including water content of the heat exchanger and related piping and components. If the mounting location cannot support a minimum of 150 lbs. (68 kg), it is recommended to locate the boiler in a mounting location that can support the minimum weight. Failure to ensure the structure of the installation location is structurally sound before installation of the boiler and properly mount the boiler can result in structural failure, substantial property damage, severe personal injury, or death. WARNING Do not mount the boiler to a hollow wall. WARNING E. Wall Mounting Instructions

WARNING

The manufacturer cannot anticipate all installation conditions. These instructions and included parts may not apply to wall mounting the appliance at your installation location. The appliance must be properly and securely mounted by a qualiÀed installer according to installation conditions, the technical speciÀcations of the appliance, and to meet AHJ / building code requirements. All applicable permits must be obtained before installing the appliance. Failure to follow these instructions could result in property damage, severe personal injury, or death. Any damages resulting from improper installation are not covered by product warranty. CAUTION If the boiler is not installed upright, vertically plumb, and level, improper and unsatisfactory operation may occur, causing excessive condensation build-up, nuisance fault codes, and unnecessary maintenance. 2. Mounting to a Wood Studded Wall 1. Position the upper wall mounting bracket on the wall. Ensure the bracket is level and the drilling holes are on stud. Then use the bracket as a template to mark four (4) drilling holes on the wall - two (2) on each side of the bracket. See Figure 5 for details. 2. Drill and plug the wall. Then secure the upper mounting bracket using the provided Fischer S 10x50 screws and eld provided washers for wood mounting. 3. Install the lower mounting bracket on the boiler. Then hang the boiler on the upper mounting bracket. Ensure the boiler is level. Then use the lower bracket to mark the lower bracket drilling holes. 4. Drill and plug the wall and secure the lower mounting bracket using eld provided screws. Then adjust the lower mounting bracket on the boiler. Ensure the boiler is installed plumb. Tighten the bracket to the boiler.

WARNING

16 “

This wall mounting system is not seismic rated and should not be applied as such.
