A space heater is a self-contained device for heating an enclosed area. Space heating is generally employed to warm a small space, and is usually held in contrast with central heating, which warms many connected spaces at once. The inspection includes ensuring manufactures installation instructions are followed and wood burning units are installed in accordance with their listing requirements. The verification of installation is done by a Certified Inspector. Space heaters which do not have a ULC or other agency's Certification Data Tag will have to have 48 inches of clearance from combustibles. This is an important part of the Inspection and home owners can easily verify for themselves whether of not their space heater is Certified prior to paying for an inspection.
