NTI INSTALLATION MANUALS

Do not attempt to vent this appliance by any means other than those described in this manual. Doing so will void the warranty and may result in severe personal injury or death. WARNING Approved Carbon Monoxide Detectors: Each carbon monoxide detector as required in accordance with the above provisions shall comply with NFPA 70 and be ANSI/UL 2034 listed and IAS certi ed. I. Prevent Combustion Air Contamination Install intake air piping for the boiler as described in the Venting Section, this manual. Do not terminate exhaust in locations that can allow contamination of intake air. b. In the event that these requirements cannot be met at the time of completion of installation, the owner shall have a period of thirty (30) days to comply with the above requirements; provided, however, that during said thirty (30) day period, a battery operated carbon monoxide detector with an alarm shall be installed. Ensure that the intake air will not contain any of the contaminants in Table 7. Contaminated air will damage the boiler, resulting in possible substantial property damage, severe personal injury, or death. For example, do not pipe intake air near a swimming pool or laundry facilities. These areas always contain contaminants. WARNING installed on each additional level of the dwelling, building, or structure served by the vented gas appliance. It shall be the responsibility of the property owner to secure the service of quali ed licensed professionals for the installation of hard wired carbon monoxide detectors. a.

J. Removing a Boiler from a Common Vent System

When removing an existing boiler, follow the steps below. 1. Seal any unused openings in the common venting system. 2. Visually inspect the venting system for proper size and horizontal pitch to determine if there is blockage, leakage, corrosion, or other de ciencies that could cause an unsafe condition. 3. If practical, close all building doors, windows, and doors between the space in which the boiler remains connected to the common venting system and other spaces in the building. Turn on clothes dryers and any appliances not connected to the common venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, at maximum speed. Do not operate a summer exhaust fan. Close all replace dampers. 4. Place in operation the appliance being inspected. Follow the lighting instructions. Adjust the thermostat so the appliance will operate continuously. 5. Test for spillage at the draft hood relief opening after 5 minutes of main burner operation. Use the ame of a match or candle or smoke from a cigarette. 6. After it has been determined that each appliance remaining connected to the common venting system properly vents when tested as outlined, return doors, windows, exhaust fans, replace dampers, and any other gas burning appliances to their previous condition of use. 7. Any improper operation of the common venting system should be corrected to conform to the National Fuel Gas Code, ANSI Z223.1. When resizing any portion of the common venting system, the system should approach the minimum size as determined using the appropriate tables in Appendix G of ANSI Z223.1. Failure to follow all instructions can result in Áue gas spillage and carbon monoxide emissions, causing severe personal injury or death. WARNING Do not install the boiler into a common vent with any other appliance. This will cause Áue gas spillage or appliance malfunction, resulting in possible substantial property damage, severe personal injury, or death. DANGER
