NTI INSTALLATION MANUALS

Part 3 - Prepare the Boiler for Installation

CAUTION

CAUTION

COLD WEATHER HANDLING - If the boiler has been stored in a very cold location (BELOW 0oF) before installation, handle with care until the components come to room temperature. Failure to do so could result in damage to the boiler. Carefully consider installation when determining boiler location. Please read the entire manual before attempting installation. Failure to properly take factors such as boiler venting, piping, condensate removal, and wiring into account before installation could result in wasted time, money, and possible property damage and personal injury.

Failure to keep the boiler area clear and free of combustible materials, liquids, and vapors can result in substantial property damage, severe personal injury, or death. 4. Gas control system components must be protected from dripping water during operation and service. 5. If the boiler is to replace an existing boiler, check for and correct any existing system problems, such as: • System leaks • Location that could cause the system and boiler to freeze and leak • Incorrectly sized expansion tank 6. Clean and ush system when reinstalling a boiler. 2. Check for nearby connections to: • System water piping • Venting connections • Gas supply piping • Electrical power • Condensate drain 3. Check area around boiler. Remove any combustible materials, gasoline, and other ammable liquids. The service life of the boiler’s exposed metallic surfaces, such as the casing, as well as internal surfaces, such as the heat exchanger, are directly in uenced by proximity to damp and salty marine environments. In such areas higher concentration levels of chlorides from sea spray coupled with relative humidity can lead to degradation of boiler components. In these environments, boilers must not be installed using direct vent systems which draw outdoor air for combustion. Such boilers must be installed using room air for combustion. Indoor air will have a much lower relative humidity, and hence potential corrosion will be minimized. Failure of the boiler or components due to incorrect operating conditions IS NOT covered by product warranty. Always take future maintenance into consideration when locating the boiler. If the boiler is located in an installation location with limited clearances, it may be necessary to remove the boiler from the space to perform maintenance. Failure to consider maintenance when determining installation location could result in property damage. NOTE: When installing in a zero clearance location, it may not be possible to read or view some product labeling. It is recommended to make note of the boiler model and serial number. Do not introduce toxic chemicals, such as antifreeze or appliance treatments, into any piping meant for potable water purposes. Do not connect DHW connections to any heating systems or components that have been previously used for nonpotable applications. Ensure that all piping and components connected to the appliance are suitable for potable water applications. Failure to follow these instructions could result in serious personal injury or death. CAUTION WARNING WARNING

A. Locating the Boiler

WARNING

This boiler is certi ed for indoor use only. DO NOT INSTALL OUTDOORS. Outdoor installations ARE NOT covered by warranty. Failure to install the boiler indoors could result in property damage, severe personal injury, or death. Incorrect ambient conditions can lead to damage to the heating system and put safe operation at risk. Ensure that the installation location adheres to the information included in this manual. Failure to do so could result in property damage, serious personal injury, or death. Failure of boiler or components due to incorrect operating conditions IS NOT covered by product warranty. This boiler must be installed upright in the vertical position as described in this manual. DO NOT attempt to install this boiler in any other orientation. Doing so will result in improper boiler operation and property damage, and could result in serious personal injury or death. 1. Installation Area (Mechanical Room) Operating Conditions • Ensure ambient temperatures are higher than 32°F / 0°C and lower than 104°F / 40°C • Prevent the air from becoming contaminated by the products, places, and conditions listed in this manual • Avoid continuously high levels of humidity • Never close existing ventilation openings • Ensure a minimum 1” clearance around hot water and exhaust vent pipes • NOTE: To prevent condensing in the fan, it is recommended to avoid prolonged exposure to temperatures below 45°F

WARNING

This boiler has a condensate disposal system that may freeze if exposed to sustained temperatures below 32°F. Precautions should be taken to protect the condensate trap and drain lines from sustained freezing conditions.

WARNING

Circulators suitable for DHW applications must be used.

Failure to take precautions could result in property damage, severe personal injury, or death.
