InCanada installations must conform with the currentCAN/CSA B149 and the Canadian Electrical CodePart 1 CSA C22.2 No.1. Where required by the author-ity having jurisdiction, the installation must conform toAmerican Society of Mechanical Engineers SafetyCode for Controls and Safety Devices forAutomatically Fired Heaters, CSD-1.Installation baseThe heater should be mounted on a level, non-com-bustible surface. Heater must not be installed oncarpeting. The heater can be installed on a com-bustible surface only when the appropriate listed floorshield base is provided. An optional listed floor shieldbase is available for factory installation with the heateron all indoor models.
