VENTING HEATER

Note: Venting/chimney materials are not supplied with heater.

WARNING

A qualified service person must install the venting system for this heater. If venting system is not properly installed and maintained, the vent safety shut-off system will pre- vent the heater from running. Follow all local codes.

WARNING

This heater has a vent safety shut-off system. This system shuts off the heater gas supply if you do not vent heater properly or the venting system is blocked. Do not operate heater if not properly vented. Do not tamper with the vent safety shut-off system. Carbon monoxide poison- ing and death may result.

WARNING

When venting this heater, follow the safety information listed below.

•Never vent heater to another room or inside a building. Only vent heater to the outdoors.

•Do not vent heater exhaust to a chimney or flue serving another solid-fuel-burning or gas appliance.

•We recommend you use flues classified as prefabricated or masonry all-fuel chimney or type-B vent. See Vent Types, page 10.

•If using old vent, check vent for soot, creosote, and loose particles. If vent is damaged, repair or replace it before using heater.

•Extend the vertical section of vent pipe at least three feet above roof penetration.

•Extend the vertical section of vent pipe at least two feet above the highest point of any roof within ten feet.

•The horizontal run of vent pipe should rise at least 1/4 inch for each foot of run.

•Support the vent pipe at least every five feet along its length. Do not use combustible materials to support vent pipe.

•Never extend vent pipe horizontally through outside wall and terminate. You must connect a vertical run of vent pipe to the horizontal run. The vertical run must be at least 25% longer than the horizontal run.

•Install vent or chimney cap that is approved for use with vented gas room heaters.

•Do not use vent pipe smaller in diameter than that of the heater draft hood outlet.
