† Total air is main air plus atomizing air plus 130 scfh for pilot air. ‡ Honeywell Ultravision Flame Detector C7027A and Honeywell Flame Supervision Protectorelay RA890G yielded 1.5 micro amps or greater for all above rates. § 30 osi is recommended atomizing air pressure for oil, but all burners will operate on oil with 22 osi atomizing air (at the burner) and 10% or more excess air. Burner will not light. • Direct spark ignition on oil is not considered a viable lighting method due to the lack of repeatability. Velocity: The distance (in inches) from the tile outlet to the point where the tile velocity pressure is 0.1"wc (1259 fpm) is 105" on gas and 105" on oil (firing stoichiometric with 16 osi main air pressure). 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.
