Unit Installation with Horizontal Termination
! NOTE: a) The horizontal run of vent must be level, or have a ¼" rise for every 1 foot of run towards the
termination . Never allow the vent to run downward . This could cause high temperatures and may
present the possibility of a fire .
b) The location of the horizontal vent termination on an exterior wall must meet all local and national
building codes .
7 . Ensure that the pipe clearances to combustible materials are maintained (Diagram 3) . Install the termination cap .
! NOTE: If installing termination on a vinyl siding covered wall, a vinyl siding standoff or furring strips must be used
to ensure that the termination is not recessed into the siding . The four wood screws provided should be replaced
with appropriate fasteners for stucco, brick, concrete, or other types of sidings .
8 . Before connecting the horizontal run of vent pipe to the vent
termination, slide the Wall Thimble over the vent pipe . The wall
thimble is required for all horizontal terminations .
9 . Slide the appliance and vent assembly towards the wall,
carefully inserting the vent pipe into the vent cap assembly .
It is important that the vent pipe extends into the vent cap at a
sufficient distance so as to result in a minimum pipe overlap of
1-¼" (32 mm) . Secure the connection between the vent pipe
and the vent cap .
10 . Install wall thimble in the center of the framed hole and attach
with wood screws (Diagram 4) .
