It might seem like a difficult job to install fireplace doors without the lintel bar, but with four simple steps you can do it yourself. These are:
– Put on protective gloves and goggles before starting your work;
– Make sure that you have all the materials needed for installation;
– Use a pencil to mark out where you need to cut your fireplace opening, then use a tape measure and draw two horizontal lines over it. Cut with an electric saw until both ends of your fire box line up – do not forget about safety guidelines! You can also ask someone else to help you if this seems like too much work;
– Finally, install the doors themselves by inserting them into place. For more details on how exactly to put in fireplace doors without lintel bar consult these instructions.
