Use the periscope kit to locate the air termination above grade. The periscope must be installed so that when
fi nal grading is completed, the bottom air slot is located a minimum 12” (305mm) above grade. The maximum
allowable vent length (including both rise and run) is 10’ (3m) for a fi replace and 8’ (2m) for a stove. An insulation
sleeve is illustrated in the top vent image below, use only when supplied with the appliance.
(The insulation sleeve is not required with a stove appliance)
