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 (H3907) 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
•
2” (51 mm) from the top when 6 ft or more above the fireplace
•
1” (26 mm) from the sides
•
1” (26 mm) from the bottom

Install the Vent System
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
®
pipe is shown in these figures; Secure Flex
®
pipe may also be used. A table summarizes each configuration’s
minimum and maximum vertical and horizontal length parameters for a variety of applications.

Vertical (Straight) Installation
1. Determine the number of straight vent sections required—See Effective Vent Length on
Pages 22 and 23
for more
information. Plan the vent lengths so that a joint does not occur at the intersection of ceiling or roof joists.
