Heat & Glo 6000XL, 6000FLS, & 6000GDVFL Install Manual

Hello, I'm a chat assistant familiar with the Heat-N-Glo 6000FLS, 6000XL, and 6000GDVFL fireplace installation and operation instructions. I have read the document, and I'm ready to help with any queries about the fireplace's installation, operation, safety measures, venting requirements, or other aspects detailed in this manual. Feel free to ask about required clearances, gas line connections or any other topic from the document.
What type of vent system is required?

Can the fireplace be installed in a bedroom?

What is the minimum clearance to combustibles for the glass front?

What should I do if I smell gas?
