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.

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
