Grand Canyon 18" to 42" Indoor Vented See Through 3-Burner System
The Grand Canyon See-Through 3-Burner System is a vented gas log burner for a see-through (two-sided) fireplace, with three burners, which gives a taller, fuller flame than the 2-burner. It is built from a ceramic-coated chassis with welded bar-stock burner tubes, for indoor fireplaces. The burner ships match-lit, without a control valve, so you can add the safety pilot, millivolt or electronic system you want.
It comes in 5 sizes from 18" to 42". Model numbers are 3BRN-ST##, where ## is the size. The burner is built for natural gas; choosing propane adds the LP conversion kit (LP-CONV: orifice and air mixer). Logs are sold separately.

What to Order With It
The burner does not include logs. Pick one log set in the same size as the burner. Our log listings are sold as logs and burner together, so if you have not bought the burner yet you can order both from the log page.
Required (choose one):
-
Arizona Weathered Oak See-Through Logs (AWOST##LOGS, sizes 18", 24", 30", 36", 42")
-
Arizona Juniper See-Through Logs (AJST##LOGS, sizes 18", 24", 30", 36", 42")

-
Western Driftwood See-Through Logs (DRIFTWOODST##LOGS, sizes 18", 24", 30", 36", 42")
Optional controls:
See-through burners run at higher BTU than front-view burners, so not every control fits every size. Tell us the size and fuel and we will confirm the right kit before you order.
Optional:
-
Twig Sets (AJTWIG3, ASPENTWIG4, AWOCTWIG3, AWOTWIG3, AWOTWIG5, DRIFTWOODTWIG3): add height and mass to the log stack
