FLASHING INSTALLATION
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.
DO NOT NAIL THROUGH FLASHING CONE.
Figure 25
STORM COLLAR INSTALLATION
Place storm collar over pipe and slide down until snug against the
open edge of the flashing (see Figure 26).
Apply waterproof caulking to all seams and notched around storm
collar and also at base around shingles.
TERMINATIONS
The firebox system must be terminated with the listed round top or
chase terminations, In any case, refer to the installation instructions
supplied with the termination.
Figure 26
The terminations approved for this firebox are VRTL-10D which can
be used for flashing or chase and VETL-10D for chase style termina-
tion only. Figure 27 shows an VRTL-10D round top termination.

CAUTION: DO NOT SEAL OPENINGS ON THE ROOF-
TOP FLASHING. FOLLOW THE INSTALLATION IN-
STRUCTIONS PROVIDED WITH THE TERMINATION
BEING USED.
CHASE INSTALLATIONS
Instructions for chase installations are included with the chase style
termination chosen although it is worthy to mention here that in a
multiple chase installation, provide adequate distance between ter-
minations or smoke spillage from one termination to another may
occur. We suggest they be separated at least 30" center to center and
stacked at a vertical height difference of 18" vertically from one
termination to the other (see Figure 28).
