Red eye located near a coal fire

[clairbear]

Hi - we are getting our first Red Eyed Tree Frogs at the weekend.
They will be on a cabinet one side of our chimney breast.
In the winter we have an open coal fire every now and then.
Will this be OK for the frogs, or should we move them out of the room - incase the smoke affects them
(it doesnt smoke that much... but I dont know if they are sensitive to it).... any advice?

Thank you
