OWNER’S MANUAL
VENTING INSTALLATION
Continued
•Situate the gas vent in the structure so that it can be installed without cutting joists, sills, plates, or major load bearing partitions or members. It is also impor- tant to locate the base of the gas vent as near as possible to the heating appliance.
•This heater must be properly connected to a venting system. This heater is equipped with a vent safety shutoff system.
•Use only vents labeled "FOR EXTE- RIOR USE" above the roofline.
•Consult the authority having jurisdiction to select the correct gas vent diameter. Avoid using a larger than necessary diameter.
