1. Ensure that the two long mounting brackets are facing the bottom of the
termination. (See inset). This will provide more heat protection at the top of
the termination, where temperatures are highest.
2. Attach to the faceplate of the termination using four sheet metal screws.
Installing Heat Guards over Terminations
Installing the Nailing
Flange Extension
Once the replace is placed into the rough framed opening and the supplied steel
lintel is in place (Part No. L42087) (see Figure 2), the supplied nailing ange
extension must be placed along the top edge of the replace and securely fastened
in place to the metal lintel and combustible wood framing. Note: The nailing ange
extension can be substituted with a piece of NON-COMBUSTIBLE material of the
same size and thermal characteristics, i.e.: cement board or equivalent.
CAUTION:
 Do not obstruct, or attempt to conceal, the vent termination. These actions
will aect the operation of the replace, and may be hazardous.
 In heavy snow areas, take extra care to prevent snow buildup from obstructing
the vent termination.
