PENETRATING THE ROOF 
 

To maintain a 2-inch clearance to the pipe on a roof with a 
pitch, a rectangular opening must be cut. 
 

STEP 1:

 Determine the center point through which the pipe 

will penetrate the roof. 
 

STEP 2:

  Determine the center point of the roof.  Pitch is the 

distance the roof drops over a given span, usually 12 inches.  
A 6/12 pitch means that the roof drops 6 inches for each 12 
inches one measure horizontally down from the roof rafters. 
 

STEP 3:

  Use the roof opening chart (figure 12) to determine 

the correct opening length and flashing required. 
 

STEP 4:

  Remove the shingles around the opening measured 

and cut out this section. 
 

STEP 5:

  Add the next sections of the pipe until the end 

penetrates the roofline.  Check to see that the proper 
clearances are maintained.  Extend chimney by adding 
sections of double wall pipe until pipe is a minimum of 30 
inches above the highest point of the roof cutout.  Termination 
and chimney must extend a minimum of 36 inches above the 
highest point where it passes through roof. 
 
 
 
 
 
 
 
 
 
 
 
 

 
 

 
 
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 ¾” screws and 
then sealed with roof coating 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.
