The purpose of a 'peep' hole in the boiler casing is to _______________.

AI Explanation
The correct answer is B) examine the condition of the flame. The purpose of a 'peep' hole in the boiler casing is to allow the operator to visually inspect the condition of the flame inside the boiler. This allows the operator to ensure the flame is burning cleanly and efficiently, which is crucial for the safe and proper operation of the boiler. The other answer choices are not the primary purpose of the peep hole, as they relate to other boiler components or functions that are not directly observed through the peep hole.
