Low Intensity Pull Through (Negative Pressure) Infrared Tube Heater - LTS Series

Pull-Through System

• Pull-through system — the products of combustion are pulled through the combustion chamber for increased radiant efficiency and greater safety
• CSA design certified for vertical or horizontal venting
• CSA design 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
• CSA design certified for vented or indirect vented operation.

Burner & Control Systems

• 3 Monitoring light system for on line diagnosis- power on, insufficient air flow, and ignition sytem operation
• Monitoring light system for on-line diagnosis
• One-piece cast iron burner with stainless steel flame retainer
• 10 year limited warranty on burner
• Inside or optional outside air for combustion
• CSA design certified for 50 ft. fresh air inlet duct
• 4″ or 6″ O.D. standard fresh air inlet duct opening for LTS40 – LTS75; 6″ for LTS80 – LTS250
• Burner inspection sight glass
• State-of-the-art redundant, step opening, combination gas valve for quiet ignition and added safety
• Diaphragm Air Proving Switch–a safety device for proof of venting before gas flow and ignition
• Direct Spark ignition system with 100% Gas Shut-Off Safety Control (30 second pre-purge)
• Quick slip-on electrical connectors and quick 115-volt terminal block connection
• Uncomplicated maintenance access
• 36″ Stainless Steel flexible gas connector included with control box

Radiant Emitter Tube System

• All radiant emitter tubes are 16 gauge, 4″ O.D. calorized steel
• Body assembly consists of 5′ and 10′ body sections that can be assembled in desired configuration (elbows and corner reflectors are optional)
• Titanium alloy Alumi-Therm and aluminized steel emitter tubes are calorized for long life and high radiant efficiency — will not flake or peel, and are corrosion resistant
• The calorization process (PDF) produces an emitter tube which is highly radiant absorptive on the interior and highly radiant emissive on the exterior
• Suitable for horizontal or angle mount up to 45 degrees
• CSA design certified for incline mounting up to 2/12 pitch roof structure
• 5 year limited warranty on the emitter tube

Reflector System

• Fully factory pre-assembled on tube body to minimize field 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

Other

• 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
