Wall Thimble and Roof Support

The Wall Thimble is used in horizontal installations to shield the combustible material from the vent pipe. The appropriate size
of thimble is required for each model. Please contact your local dealer for more information. Refer to Side Wall Venting for wall
cutout information.
The Roof Support is used to secure the vertical venting as it penetrates the roof. Please note that you may only install the roof
support to a rigid pipe.
