LTS Series Tube Heater

Specifications | Dimensions | Supply Requirements | Clearance Info.

Specifications

Features

  • 19 different Btu sizes and more than 100 different configurations to custom design your radiant heating system
  • Factory pre-assembled for easy and low-cost installation
  • Pull-through system for increased radiant efficiency
  • Calorized aluminized steel emitter tubes and highly efficient aluminum reflectors to enhance radiant output
  • Single stage or two stage modulating input.

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
  • 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

  • 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 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 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
  • Shipped factory assembled on tube body
  • Highly efficient aluminum reflectors
  • Reflector ends are enclosed for maximum radiant heat output and minimum convection loss
  • Easy-to-use mounting brackets

NOTE: The clearances specified above must be maintained to combustibles and other materials that may be damaged by temperatures 90ºF above ambient temperature. Clearances to combustibles are posted on the reflector near the control end of the heater. In locations used for storage of combustible materials where they may be stacked below the heater, NFPA 54 requires that the installer must post signs that will "specify the maximum permissible stacking height to maintain the required clearances from the heater to combustibles".

* When used indirect vented, the clearance to the ceiling from the top of the exhaust hood must be 12" for LTS40--LTS75, 18" for LTS80--LTS175, and 24" for LTS180--250.

**72" clearance 20’ downstream from the Control Box

NOTE: Consult the factory if reduced clearances are required. Also, please note that this heater is NOT for residential use.
