Can anyone tell me roughly how old a Large wood-burning Napoleon fireplace insert might be?  It has the gold door and a brown backplate, but the blower is below the door and pulls out easily. Is this unit catalytic or non-catalytic?  The seller is a new occupier of the house and has no info.  Is this model any better or worse than the current 1400 series?
Thanks for any news
