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.

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.

The terminations approved for this firebox are VRTL-10Dwhich can be used for flashing or chase and VETL-10Dfor 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).
