12 C. CLEARANCES FOR SERVICE ACCESS See Figure 2 for recommended service clearances. If you do not provide the minimum clearances shown, it may not be possible to service the heater without removing it from the space. Figure 2 – Required Clearances Space must be provided with combustion/ventilation air openings correctly sized for all other appliances located in the same space as the heater. The heater cover must be securely fastened to prevent the heater from drawing air form the heater room. This is particularly important if the heater is in a room with other appliances. Failure to comply with the above warnings could result in substantial property damage, severe personal injury, or death. D. RESIDENTIAL GARAGE, CLOSET, AND ALCOVE INSTALLATIONS Check with your local Authority Having Jurisdiction for requirements when installing heater in a garage, closet, or alcove. Please read the entire manual before attempting installation. Failure to properly take factors such as heater venting, piping, condensate removal, and wiring into account before installation could result in wasted time, money, and possible property damage and personal injury. PRECAUTIONS If the heater is located in a residential garage, per ANSI Z223.1: Mount the bottom of the heater a minimum of 18” above the floor of the garage, to ensure the burner and ignition devices are well off the floor. Locate or protect the heater so it cannot be damaged by a moving vehicle. For closet or alcove installations, a two pipe venting system must be used. Failure to follow this warning could result in substantial property damage, severe personal injury, or death. The space must be provided with correctly sized combustion/ventilation air openings for all other heaters located in the space with the heater. Do not install the heater in an attic. Failure to comply with these warnings could result in substantial property damage, severe personal injury, or death. NOTE: For installations using room air for combustion, refer to the heater venting section, Part 6 in this manual. LP-171 Rev. 10.2.13
13 E. EXHAUST VENT AND INTAKE PIPE Vents must be properly supported. Heater exhaust and intake connections are not designed to carry heavy weight. Vent support brackets must be within 1’ of the heater and the balance at 4’ intervals. Heater must be readily accessible for visual inspection for the first 3’ from the heater. The heater is rated ANSI Z21.13 Category IV (pressurized vent, likely to form condensate in the vent) and requires a special vent system designed for pressurized venting. You must also install air intake piping from outdoors to the heater flue adaptor. The resultant installation is categorized as direct vent (sealed combustion). NOTE: To prevent combustion air contamination, see Table 1. Exhaust and intake must terminate near each other and may be vented vertically through the roof or out a side wall. Exhaust vent and intake piping methods are detailed in the Venting Section. Do not attempt to install the heater using any other means. Be sure to locate the heater such that the exhaust vent and intake piping can be routed through the building and properly terminated. The exhaust vent and intake piping lengths, routing and termination method must all comply with the methods and limits given in the venting section. F. PREVENT COMBUSTION AIR CONTAMINATION Install intake air piping for the heater as described in the Venting section. Do not terminate exhaust in locations that can allow contamination of intake air. PRODUCTS TO AVOID Spray cans containing fluorocarbons Permanent wave solutions Chlorinated waxes/cleaners Chlorine-based swimming pool chemicals Calcium chloride used for thawing Sodium chloride used for water softening Refrigerant leaks Paint or varnish removers Hydrochloric or Muriatic acid Cements and glues Antistatic fabric softeners used in clothes dryers Chlorine-type bleaches, laundry detergents, and cleaning solvents Adhesives used to fasten building products Table 1 - Contaminant Table AREAS LIKELY TO HAVE CONTAMINANTS Dry cleaning/laundry areas and establishments Swimming pools Metal fabrication plants Beauty shops Refrigeration repair shops Photo processing plants Auto body shops Plastic manufacturing plants Furniture refinishing areas and establishments New building construction Remodeling areas Garages and workshops You must pipe outside air to the heater air intake. Ensure that the intake air will not contain any of the contaminants listed in Table 1. For example, do not pipe intake near a swimming pool. Also, avoid areas subject to exhaust fumes from laundry facilities. These areas always contain contaminants. Contaminated air will damage the heater, resulting in possible substantial property damage, severe personal injury, or death. NOTE: DAMAGE TO THE HEATER CAUSED BY EXPOSURE TO CORROSIVE VAPORS IS NOT COVERED BY WARRANTY. (Refer to the limited warranty for complete terms and conditions). G. REMOVING AN EXISTING HEATER FROM AN EXISTING COMMON VENT SYSTEM Do not install the heater into a common vent with any other appliance. This will cause flue gas spillage or appliance malfunction, resulting in possible substantial property damage, severe personal injury, or death. Failure to follow all instructions can result in flue gas spillage and carbon monoxide emissions, causing severe personal injury or death. When removing an existing heater, follow the steps below with each appliance remaining connected to the common venting system in operation, while other appliances remaining connected to common venting system are not operating. 1. Seal any unused openings in the common venting system. LP-171 Rev. 10.2.13
