•  On a pitched roof, install the Flashing 
with the upper edge under the 
existing roong material. Center the 
Flashing over the roof framing. Then 
seal and nail the Flashing into place 
along the upper edge and down 
each side with 1" roong nails. Do not 
nail the lower edge of the Flashing. 
Seal the top and upper sides of the 
Flashing, and all exposed nail heads 
with roong compound or sealant.
•  On a at roof, nail and seal the 
Flashing on all sides with roong 
compound. Do not put screws 
through the Flashing into the vent 
pipe. Follow all local building practices 
as needed.

1.  Locate the penetration in the roof 
(
Fig.25)
. Measure the intended path of the 
installation and make sure you have all the 
necessary components to complete the 
install. 
2.  Cut and frame the roof penetration 
following the dimensions in Table 3. Make 
sure no debris falls into the appliance 
intake or outlet.
3.  Use the appropriate roof ashing for 
the roof type. On a pitched roof, use the 
Adjustable Flashing for 0/12 to 5/12 pitch 
and the Steep Roof Flashing for 5/12 to 
12/12 pitched roofs. On a at roof, use the 
aluminum Flat Roof Flashing.
