General Tools Inspection Mirror 759563

The General Tools 759563 is an inspection mirror for viewing concealed components during service and diagnostic work.

Heat exchanger inspection is the application where an inspection mirror carries the most weight, because the finding is a safety matter.

A cracked or perforated heat exchanger in a gas fired appliance allows combustion products to enter the supply air, and that includes carbon monoxide. The consequences are potentially fatal, and the appliance must be shut down and either repaired or replaced rather than returned to service.

The difficulty is that heat exchanger surfaces are largely inaccessible. Cracks commonly form at the hottest and most stressed areas, which are rarely visible through the burner opening or the inspection port, and a crack may be visible only when the metal is hot and expanded.

A mirror and a good light allow far more of the surface to be examined than direct viewing permits, and combining that with the other available methods gives a more reliable assessment.

Those other methods include observing burner flame behaviour as the circulating blower starts, carbon monoxide measurement in the supply air and the flue, and inspection cameras where access is very poor.

No single method is conclusive on its own, and a suspicion of heat exchanger failure warrants thorough investigation rather than a judgement made quickly.

Confirm mirror size and handle reach suit the appliances serviced, and keep the surface clean.
