Note: If exhaust collar on insert and fireplace damper do not line up, add 4 inches (102 mm) to minimum fireplace
height for bends in vent pipe.
Custom Surrounds
Custom surrounds are available. See your dealer for information. Standard surrounds are 3/4 inches deep. Custom
surrounds are available up to 3 inches deep. A 3 inch deep surround would reduce the unit opening depth
(E*)
by 2-1/4
inches (3 in. - 3/4 in. = 2-1/4 in).
On Site Custom Surrounds
On site custom surrounds are available. See your dealer for information. On site custom surrounds are flush and have
no depth. A flush surround would increase the unit opening depth
(E*)
by 3/4 inch.
