VENT TERMINATION
Framing for vents in combustible walls and ceilings:
When passing through combustible walls and ceilings, framing will depend on the type of vent installation -- horizontal
or vertical. Ensure that the insulation is kept clear of the vent pipe using either a wall thimble or an attic insulation
shield. Follow the installation instructions supplied with the individual venting components.
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/CSA-
B149.1 in Canada.

Instructions
•
Where a vent pipe passes through a floor or ceiling, a ceiling firestop MUST be used to retain insulation and
maintain proper clearances. Use roof support brackets where needed.
•
Install the first section of vent pipe into the collar on top of the fireplace.
•
Connections between each vent system component must be tightly joined and secured. Follow the vent
manufactur
er’s
instructions for information on how to seal and secure vent and vent connections.
•
Horizontal runs of vent pipe must be supported to prevent any downward sags. Horizontal pipe sections should
be supported at least every 4 feet. Wall Straps can be used for this purpose.
•
When installing the vent pipe, make sure that the vent pipe is supported by the structural/frame surrounding and
not by fireplace.
Follow the vent manufacturer
’s
instruction for information on how to install, seal, and secure vent and vent
connections.
DO NOT pack insulation around the vent. Insulation must be kept back from the pipe to prevent overheating.
ALWAYS maintain specified clearances around venting and firestop systems. Install wall shield and ceiling firestops as specified.
