SCOTTY SS – INSTRUCTION MANUAL OPERATING INSTRUCTIONS INTRODUCTION Congratulations on your purchase of the KERR SCOTTY SS Wood Furnace. Developed in Atlantic Canada, this KERR Furnace has been designed to allow you to heat your home with wood, one of North America’s most abundant fuels. Designed with you in mind, the KERR SCOTTY SS Wood Furnace will provide you with many years of safe, efficient central heating.
SCOTTY SS – INSTRUCTION MANUAL CREOSOTE Wood combustion is never 100% complete. Wood smoke always contains some unburned gases and a mixture of unburned tar-like liquids. A percentage of these materials will condense out on any cool surface, leaving a dark brown or black substance with an unpleasant acrid odor.
SCOTTY SS – INSTRUCTION MANUAL MAXIMUM SOLID-FUEL CHARGE The maximum level for a solid-fuel charge is the middle of the loading door, or the level of the handle. DO NOT OVERFILL. The KERR SCOTTY SS Wood Furnace will accept whole or split logs up to 27 inch (686 mm) long, but a 24-inch (610 mm) log length is recommended for convenience and ease in handling.
SCOTTY SS – INSTRUCTION MANUAL 1.5.2 SERVICING The furnace air filter must be checked monthly and replaced when necessary. Annually lubricate the blower motor, if it is not permanently lubricated, with 4-6 drops of SAE-30 oil in each bearing.
