Where should the firematic disconnect switch be located in relation to the oil-fired unit?

The firematic disconnect switch is designed to provide a quick way to shut off power to the oil burner in case of an emergency, such as a fire. Placing the switch at the unit, near the burner, and within arm's reach ensures that a technician or operator can quickly access it in a critical situation. This proximity allows for a rapid response, which is essential for safety, particularly when dealing with oil-fired equipment that can pose significant fire hazards.

This location also aligns with safety regulations and best practices in oil heating systems. Being within arm's reach means that the operator does not need to navigate through obstacles or exit the building to reach the switch, which could waste valuable time and potentially create a greater risk.

While options such as location outside the building or at a safe distance from fire hazards are relevant safety considerations, they do not provide the immediacy needed in an emergency. The disconnect needs to be accessible, thus reinforcing the choice of having it near the burner.
