      • Up to 50 ft. outside combustion air ducting capability

      Pull-Through System (negative pressure or vacuum)

      • Pull-through system — the products of combustion are pulled through the combustion chamber for increased radiant efficiency and greater safety
      • CSA certified for vertical or horizontal venting
      • CSA certified for maximum 75 ft. horizontal sidewall venting
      • 4″ O.D. flue connection for LTU40-LTU175; 6″ for LTU180-LTU250
      • Draft inducer is equipped with permanently lubricated, totally enclosed, fan cooled and heavy duty ball bearing motor for maintenance free operation
      • Draft inducer assembly can be used for through- the-roof-venting or rotated 45 degrees or 90 degrees for horizontal venting
      • No draft hoods, totally enclosed combustion chamber

      Burner System

      • One piece cast iron burner with stainless steel flame retainer
      • 10 year limited warranty on burner
      • Inside or optional outside air for combustion
      • CSA certified for 50 ft. outside combustion air inlet duct
      • 4″ O.D. standard fresh air inlet duct opening for LTU40-LTU75; 6″ for LTU80-LTU250
      • Burner inspection sight glass
      • State-of-the-art step opening combination gas valve for quiet ignition
      • Diaphragm Air Proving Switch — a safety device for proof of venting before gas flow and ignition
      • Spark ignition system with 100% Gas Shut-Off Safety Control (30 second pre-purge)
      • 36″ Stainless Steel flexible gas connector included with control box

      Radiant Emitter Tube System

      • All radiant emitter tubes are 16 gauge calorized steel — 3″ for LTU40-LTU75 and 4″ for LTU80-LTU250
      • Body assembly for some models is 15′ long; other models require the use of additional 5′ and 10′ body packages
      • Titanium alloy Alumi-Therm and aluminized steel emitter tubes are calorized for long life and high radiant efficiency
      • The calorization process (PDF)produces an emitter tube which is highly radiant absorptive on the interior and highly radiant emissive on the exterior
      • 5 year limited warranty on the emitter tube

      Reflector System

      • Fully factory pre-assembled on tube body to minimize field filed assembly and save installation labor cost
      • Highly efficient aluminum reflectors with reflectivity rating of 97%
      • Reflector ends are enclosed for maximum radiant heat output and minimum convection loss
      • Easy to use mounting brackets
      • Suitable for horizontal or angle mount up to 45 degrees

      Other

      • 3 Monitoring light system for on line diagnosis- power on, insufficient air flow, and ignition sytem operation
      • Uncomplicated maintenance access
      • Quick slip-on electrical connectors
      • Quick 115 volt terminal block connection
      • 1/2″ MPT gas inlet connection
      • CSA approved for direct vented or indirect vented operation
      • Optional deflector kit for reduced clearances to combustible materials
      • Optional decorative grille kit for drop ceiling applications
      • Optional side reflector kits
      • CSA Certified according to ANSI Z83.20 and CSA 2.34. NOT Certified for Residential Use
