Welcome to the HVAC-Talk section to Ask Our Pros about fireplaces, chimneys, hearth appliances and venting! Please read the AOP rules before posting. We will try to answer you as fully, courteously and professionally as we are allowed by Site Rules. Please pay special attention to the disclaimers, which may address a lot of questions out of hand.
Keep in mind we are not physically at your house so you will need to describe what you have or what you are contemplating including make, model, mfg. date where possible and so on. It's pretty hard to give us too much information but very easy to omit relevant details.
