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 15). 
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) 
 

Place storm collar over pipe and slide down until it is snug 
against the open edge of the flashing (see figure 16).  Apply 
waterproof caulk around the perimeter of the collar to provide 
a proper seal. 
 
 

Note: Storm collar is required but can be installed after the 
home is sited. 
 
 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
TERMINATIONS / SPARK ARRESTOR 
 

The fireplace system must be terminated with the listed round 
top or chase terminations.  In any case, refer to the installation 
instructions supplied with the termination.  The terminations 
approved for this fireplace are the RTL-8DM, which can be 
use for flashing or chase and the ETL-8DM, for chase style 
termination only. Figure 17 shows an RTL-8DM round top 
termination. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 
 
 
NOTE: 

In the rare instance there is a problem with the side 

driven rain or wind or the chimney is not drafting properly, an 
ADS-8DM Anti Draft Shield can be used with round 
terminations.
