As you know, the Board of Fire Prevention Regulations, pursuant to M.G.L. c. 148 s. 25A has promulgated regulations to allow the sale and use of unvented LP or natural gas fired heaters. These regulations are promulgated at 527 CMR 30.00. In accordance with 527 CMR 30.04 (2) only appliances listed in accordance with the Massachusetts Fuel Code (248 CMR) are approved for sale and use in Massachusetts.
Recently, the Department of Fire Services' compliance officers have observed non-compliant unvented gas heaters being sold at both Home Depot and Lowe's stores. Both have been served by my office with Cease & Desist notices at their corporate headquarters.
Please take note that only approved unvented gas heaters are being sold in your jurisdiction. You may access 527 CMR 30.00 by going to the Department of Fire Services home page. In addition, you can access 248 CMR through a link on the Department of Fire Services home page to obtain a current listing of approved appliances by entering the manufacturer's name and model number .
