Clearance to combustibles
Maintain the minimum clearance to combustibles (e.g., framing, attic, ceiling insulation, etc.).
For all vertical runs:
• 1" (26 mm) from all sides
NOTE: Attic insulation shield (H3908) must be installed when blown or loose-fill insulation is used, and is recommended
for all attic installations.
For all horizontal/inclined runs:
• 3" (77 mm) from the top
• 1" (26 mm) from the sides

Install the Vertical Termination Vent System
These instructions should be used as a guideline and do not supersede local codes in any way. Install venting according
to local codes, these instructions, the current National Fuel Gas Code (ANSI-Z223.1) in the USA or the current standards
of CAN/CGA-B149.1 in Canada.
Ensure clearances are in accordance with local installation codes and the requirements of the gas supplier.
Dégagement conforme aux codes d'installa tion locaux et aux exigences du foumisseunde gaz.
Vertical vent systems terminate through the roof. The minimum vent height above the roof and/or adjacent walls is
specified in ANSI Z223.1 (In Canada, the current CAN/CGA-B149.1 installation code) by major building codes. Always
consult your local codes for specific requirements. A general guide to follow is the gas vent rule (Table 6).
The following figures and their associated vertical vent tables illustrate the various configurations that are possible for
use with these fireplaces. Secure Vent
summarizes each configuration's minimum and maximum vertical and horizontal length parameters for a variety of
applications.
1. Refer to Figure 23, Table 19, and Table 20 on Pages 28-29 to select the type of vertical installation desired. Elbows
are available in 90° and 45° configurations. Refer to Figure 20 on Page 23 for the SV4.5E45 and SV4.5E90 elbow
dimensional specifications.
Vertical (Straight) Installation
1. Determine the number of straight vent sections required—See Effective Vent Length on Page 22 for more
information. Plan the vent lengths so that a joint does not occur at the intersection of ceiling or roof joists.
