Set Sizing for a See-Through Fireplace

QUESTION: How do you size a log set for a see-through fireplace?

ANSWER: Almost all Rasmussen gas log and ALTERNA styles are available in “Double Face” for see-through fireplaces.
• Vented set using a safety control, subtract 12” from the fireplace opening width and round down to the nearest set size.
• Vented set that is to be match lighted (natural gas only), subtract 6” from the fireplace opening width and round down to the nearest set size.
• Vent-free set, subtract 6” from the fireplace opening width and round down to the nearest set size.
