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
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
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.
• Do not use dampers in the vent pipes.
• Vertical height of vent must be greater than five feet
above vent connection at draft hood.
