If you rented a unit with a fireplace that burns wood and there was nothing in writing stated that the landlord would not have it fixed so as to work before you took possession of the unit, you are entitled to have a working fireplace.I would write the landlord a note advsing him or her that the fireplace needs to be taken care of by a certain date. Keep a copy of the letter. If the cut off comes and goes without the fireplace getting repaired, call a repair person and have him or her repair the unit sending the bill to the landlord for payment.
