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
• 1” (26 mm) from the sides
• 1” (26 mm) from the bottom

These instructions should be used as a guideline and do not supersede local codes in any way. Install venting with
the most restrictive requirements as outlined in these instructions, 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

The following figures and their associated vertical vent tables illustrate the various configurations that are possible
for use with these fireplaces. Secure Vent

pipe may also be used.
A table summarizes each configuration’s minimum and maximum vertical and horizontal length parameters for a
variety of applications.
