venting requirements
2.2 special vent installations
2.2.1 periscope termination
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)
