Failure to maintain overlap could cause overheating and
fire.

outside edges of cap.
• When installing a horizontal termination cap, follow
the cap location guidelines as prescribed by current
ANSI Z223.1 and CAN/CGA-B149 installation codes
and refer to Section 4 of this manual.
CAUTION! Risk of Burns! Local codes may require in-
