  1. The opening of my fireplace measures 27.75W X 24.0 H. Does the extra 3/4 inch of width really preclude me from purchasing any of you products?

    1. Hello Ben,
      Based on the measurements you provided, none of the fireplace doors from the pleasant hearth range will be able to accommodate your fireplace opening. The doors require a 30″W minimum in order to be properly installed. If you need additional information, give the GHP Customer Service group a call at 877-447-4768. Thank you.

  2. my goal is to have the fireplace doors closed when burning in the fireplace and to draw the combustion air from the vent to the outside. won’t the tempered glass be sufficient to resist shattering due to the heat generated by the fire?

  3. Seems like when I try to tighten the upper T brackets on the fireplace lintel, one always seems to slip just when I think I get to point of a firm fit…. This seems to cause the whole unit to ultimately fall out , usually while a fire is in the fireplace.. Any suggestions?

  4. Hi, We just received our Pleasant hearth GR-7201 Grandoir door from Amazon. We’d measured our opening carefully, & came up with 37″ wide — at the top. So we bought a medium. When I test-fitted the unit, I had a gap of about 1/4″ at the bottom on both sides. The top is fine. Can we use a silicone caulk to safely and aesthetically seal the quarter of an inch on each side? Or dow e need to return the unit? Thanks.

  5. Is it necessary to drill into the lintel if the bar is less than 3″? I’m trying not to have to do that. Any chance I could use a second set of (I) screws to allow for a slightly smaller lintel?

  6. I dont appear to have a lintel–its angled up directly from the brick and there appears to be a metal plate. The traditional brackets the fireplace doors come with wont work. Can I screw the bracket directly into the metal sheet? Thanks,

  7. Ordered FN-5702 from Amazon. When trying to install even with the T-bracket facing up the lentil bar in the fireplace is still about 1 inch below the bracket. Any hardware available to fix this? We really love this this door and don’t want to return it.

  8. The real stone fireplace in my home has an 80s vintage metal insert that I want to remove and replace with doors. The original firebox opening is 40.5″ wide by 27.75″ tall with a 3.5″ lintel which suggests that one of your large doors will work. My question is about the mantel face. Being made of irregularly shaped stones, the face is not square around the firebox opening with some stones protruding 1-2″ into the firebox opening. For the same reasons the face is not a smooth mounting surface on the front. Will one of the doors still work?

  9. My fireplace opening is 27.5″ H and 35″ W so it falls into the dimensions for both small and medium, which is my best choice?
