Firestats are commonly installed in air duct systems to control the spread of fire and smoke when air temperature exceeds a pre-determined temperature. A simple control that is just as simple to install.
- Adjust the temperature dial to determined temperature (Click here for more information.)
- Install into the air duct system downstream of air flow.
- Wire the firestat to a fan

How to Install Firestat in HVAC System
The CEMCO TC Series Firestat is a push-button manual reset limit control designed for prevention of fire in warm air ducts. It may be used with gas, oil or electric forced warm air heating systems.
One or more firestats should be installed in duct work at critical temperature locations such as downstream from electric heaters, points where duct work is in close proximity to flammable materials, etc.
Firestats may be used in low voltage or line voltage circuits and are usually wired to open circuit to both heat source and blower when duct air temperature exceeds the temperature setting. If more than one firestat is connected to controls a single heat source, the firestats must be connected in series.
