FLASHING INSTALLATION (V6F-8DM 
OR V12F-8DM)

Determine the flashing to be used with the roof 

opening chart. Slide flashing over pipe until base 

is flat against roof. Replace as many shingles as 

needed to cover exposed area and flashing base. 

Secure in position by nailing through shingles 

(see  Figure  13).  DO  NOT  NAIL THROUGH 

FLASHING CONE.

Installing Flashing on a Metal Roof

When installing the flashing on a metal roof, it is 

required that putty tape be used between the flashing 

and the roof. The flashing must be secured to the roof 

using #8 x 3/4" screws and then sealed with roof coat-

ing to prevent leakage through the screw holes. A roof 

coating must also be applied around the perimeter of 

the flashing to provide a proper seal.

Storm Collar Installation (SC1 or SC2)

Place storm collar over pipe and slide down until 

it is snug against the open edge of the flashing (see 

Figure 14). Use SC1 for all round terminations and 

SC2 for all terminations with slip sections. Apply 

waterproof caulk around the perimeter of the collar 

to provide a proper seal.
