*SIDE VIEW*

L Length (The shorter of the 2 L's)
W Width (The shorter of the 2 W's)
FAL Flue Area Length
FAW Flue Area Width
FH Flue Height (Height of the tallest Flue liner)
Material (Choose either Stainless Steel or Copper)

The minimum base size is FAL X FAW

The maximum base size is (shortest L minus 4") X (shortest W minus 4") - Example: L= 72", W= 28", the maximum base size would be 68" X 24"

The screen height should be at least 4" higher than FH - (the tallest flue liner).

Note: The maximum base size is the ideal size - this will give the most protection and achieve the most balanced look.

Choose a stock Multi-Flue cap or design your own top mount chimney cap using the diagram below.

Base Size (Use explanation above to figure base length & width)
