VENTING - HORIZONTALLY USING SIMPSON
INSTALLATION PROCEDURES FOR SIMPSON
5.Mark the wall with an 11” (279 mm) x 10” (254 mm) hole. See termination framing on page 22. The center of the hole should line up with the centerline of the horizontal pipe. Cut and frame the 11” (279 mm) x 10” (254 mm) hole in the ex- terior wall where the vent will be terminated. If the wall be- ing penetrated is constructed of
horizontal vent termination on an exterior wall must meet |

local and national building codes, and must not be blocked |

It is important that the vent pipe extend into the vent cap |
| |
sufficient distance so as to result in a minimum pipe overlap |
| |
of 1 ¼” (31 mm). Secure the connection between the vent |
| |
pipe and the vent cap by attaching the two sheet metal |
| |
strips extending from the vent cap assembly into the outer |
| |
all of the vent pipe. Use the two sheet metal screws pro- |
| |
vided to connect the strips to the pipe section. Bend any re- |
| |
maining portion of the sheet metal strip back towards the |
| |
vent cap, so it will be concealed by the Wall Thimble Cover. |
