![]() The installation must conform to written Instalation & Operating Instructions and local codes. Installation and service must be performed by a licensed contractor. An indirect vented installation requires a minimum ventilation flow of 4 CFM per 1000 BTU/hour of total installed heater capacity on natural gas by either gravity or power ventilation (4.18 CFM per 1000 BTU/hour on propane). A vented installation must be vented outside the building with a flue pipe. Heaters can be common vented, vented or indirect vented. Maintain 30″ side clearance with deflector.In Canada, the clearances below the heater are: CB(50,40) – 48″ (36″ with deflector) and CB(30,20) – 36″ (27″ with deflector).In U.S., the clearances below with deflector are: CB(50,40) – 42″ and CB(30,20) – 33″.Certified for Residential and Commecial Use CSA Certified according to ANSI Z83.20 and CSA 2.34.Optional decorative grille kit for drop ceiling applications. ![]() Optional deflector kit for reduced clearances to combustible materials.CSA approved for indirect vented operation- commercial installations only.3 Monitoring light system for on line diagnosis- power on, insufficient air flow, and ignition sytem operation.Suitable for horizontal or angle mount up to 45 degrees.Reflector ends are enclosed for maximum radiant heat output and minimum convection loss.Highly efficient aluminum reflectors with reflectivity rating of 97%.Fully factory pre-assembled on tube body to minimize field assembly and save installation labor cost.5 year limited warranty on the emitter tubes.The calorization process (PDF) produces an emitter tube which is highly radiant absorptive on the interior and highly radiant emissive on the exterior.Aluminized steel emitter tubes are calorized for long life and high radiant efficiency - will not flake or peel, and are corrosion resistant.36″ Stainless Steel flexible gas connector included with control box.Spark ignition system with 100% Gas Shut-Off Safety Control (30 second pre-purge).Diaphragm Air Proving Switch - a safety device for proof of venting before gas flow and ignition.State-of-the-art step opening combination gas valve for quiet ignition.standard combustion fresh air inlet duct opening Inside or optional outside air for combustion.Draft inducer assembly can be used for through- the-roof-venting or rotated 45 degrees or 90 degrees for horizontal venting.Draft inducer is equipped with permanently lubricated, totally enclosed, fan cooled and heavy duty ball bearing motor for maintenance free operation.CSA certified for vertical or horizontal venting.Pull-through system - the products of combustion are pulled through the combustion chamber for increased radiant efficiency and greater safety.Pull-Through System (negative pressure or vacuum)
