Cold Blocker Infrared Heater - CB Series®

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
• 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

Burner System

• One piece cast iron burner
• 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 combustion fresh air inlet duct opening
• 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 3″ O.D
• Aluminized steel emitter tubes are calorized for long life and high radiant efficiency — will not flake or peel, and are corrosion resistant
• The Calorization 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 tubes

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
• 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 system operation
• Uncomplicated maintenance access
• Quick slip-on electrical connectors
• 1/2″ MPT gas inlet connection
• CSA approved for indirect vented operation- commercial installations only
• 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. Certified for Residential and Commercial Use
