Pellet Venting Charts - Quadra-Fire CASTILE-MBK-B Installation Manual

CASTILE FREESTANDING
I. Pellet Venting Charts
The maximum horizontal venting allowed with no vertical vent-
ing attached is 48 inches (1219mm) including one 90° elbow
or two 45° elbows. This is our recommended horizontal vent-
ing installation. Addition of any horizontal venting beyond 48
inches (1219mm) Hearth & Home Technologies strong recom-
mends a minimum of 60 inches (1524mm) of additional ver-
tical vent. Horizontal sections of vent pipe should have a 1/4
inch (6.35mm) rise per foot.
Hearth & Home Technologies recommends any installation
requiring more than two 90° elbows, or more than 15 feet
(4.5m) of venting to use 4 inch (102mm) vent.

NOTICE: These are guidelines for successful venting of your pellet appliance. The more vertical rise you can obtain in
your system, the better it will perform. Horizontal vent runs can accumulate ash and will need to be cleaned more often.
Try to keep them as short as possible.
