    How do I obtain a written wood stove exemption as my baseboard heat will not keep my main living area above 62 degrees when the temperature drops below 40 degrees outside.

    Hello, I lived in King County and I would like a wood stove exemption. Can you please direct me to the appropriate agency? Are there conditions defined for the exemption since my stove was designed and manufactured in France. The stove meets their regulations for both coal and word burning as the fuel source. Thanks in advance for your help. Tim

    I just read Mr. Mack’s comments and I to have the same problem of maintaining proper heat from my baseboard when the outside temp. drops.
    I live in Snohomish Co. and have a pellet stove. If you can direct me to the proper agency to inquire about a written exemption that would be helpful.
    Thank you.

    I live in Klickitat County which is currently under an outdoor burn ban. Can my neighbor use his containerized wood fire BBQ in his backyard during this burn ban? He claims it has a grate and a screen.
