  • To use:
    Remove the top lid to expose the cap's surface. Light scratch the black button with the surface of the lid and drop ChimFex in next to the fire in your heating appliance. 

    ChimFex Chimney Fire Suppressant is not approved or permitted as an alternative for fire extinguishers in buildings or motor vehicles that require fire extinguishers by law, ordinance, or fire marshall regulations.

  • Please note:
    Due to internal variations in chimneys and wood burning stoves, larger flues may require two or more units, activated simutaneously, to suppress a fire.
