Refer to local codes for recommended installation information. Use black iron pipe for oil lines. Use an oil resistant pipe joint compound. Suction line intake should be at least 2" off bottom of tank to allow for water and sediment accumulation. In large tanks, clearance up to 6" is recommended. Suction line must be as short as possible and absolutely leak tight to prevent pulling air into oil system. Suction line should pitch toward tank. All "take offs" to oil burners should be made from the bottom of main oil line piping to prevent air bubbles from entering burners. Burner should be above oil manifold to avoid oil siphoning through burn er. WARNING: Situations dangerous to personnel and property may exist with the operation and maintenance of any combustion equipment. The presence of fuels, oxidants, hot and cold combustion products, hot surfaces, electrical power in control and ignition circuits, etc., are inherent with any combustion application. Components in combustion systems may exceed 160°F (71°C) surface temperatures and present hot surface contact hazard. Fives North American Combustion, Inc. suggests the use of combustion systems that are in compliance with all Safety Codes, Standards, Regulations and Directives; and care in operation.
