1 Installation Instructions Blower Packages For Gas Furnaces KCBBA00TG KCBBA00TG NOTE: Read the entire instruction manual before starting the installation. INTRODUCTION When upgrading a Coleman, Intertherm, or Miller gas furnace for use with an outdoor heat pump or air conditioner, the blower motor assembly must always be changed out. Two kits cover this change out conversion. Kit KCBBA00TG covers the conversion of Coleman 00B, 00C, 00/D, /D, C, DGRT and DLRS series, Intertherm MGHA, and Miller MMHA in -/-, -, -/-, and -ton gas furnaces. Kit KCBBA00TG covers the conversion of Coleman 00B, 00C, 00/D, /D, C, DGRT and DLRS series, Intertherm MGHA, and Miller MMHA in gas furnaces above tons. SAFETY CONSIDERATIONS Installing and servicing heating equipment can be hazardous due to gas and electrical components. Only trained and qualified personnel should install, repair, or service heating equipment. Untrained personnel can perform basic maintenance functions such as cleaning and replacing air filters. All other operations must be performed by trained service personnel. When working on heating equipment, observe precautions in the literature, tags, and labels attached to or shipped with the unit and other safety precautions that may apply. Follow all safety codes. In the United States, follow all safety codes including the National Fuel Gas Code NFPA No. -/ANSI Z.-. In Canada, refer to the current edition of the National Standard of Canada CAN/CGA- B.- and.-m Natural Gas and Propane Gas Installation Codes. Wear safety glasses and work gloves. Have fire extinguisher available during start-up, adjustment, and service call procedures. Recognize safety information. This is the safety-alert symbol alert to the potential for personal injury.. When you see this symbol on the furnace and in instructions or manuals, be Understand the signal word DANGER, WARNING, or CAUTION. These words are used with the safety-alert symbol. DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies a hazard that could result in personal injury or death. CAUTION is used to identify unsafe practices which would result in minor personal injury or product and property damage. WARNING: Before installing or servicing system, always turn off main power to system. There may be more than disconnect switch. Turn off accessory heater power if applicable. Electrical shock can cause personal injury or death.
