Vent Requirements (continued)
The vent termination must meet the following requirements:
¥ Vent termination must have an approved cap (to prevent water from entering)
¥ Vent termination must not be located where it will become plugged by snow or
other material
¥ Vent termination must extend a minimum of 6" above the top of the chimney
NOTE: When installed, the vent must provide suitable draft for the
appliance. Other factors, such as exhaust fans, may create negative
pressure inside the home and cause down drafts. Additional vent
height may be required in these circumstances.
How to tell if you have negative pressure:
The most common indication of a negative pressure situation is the heater (and pilot) turning off
between 10 and 25 minutes from the time the main burner was started (this happens most often on
cold days). The main burner turns on, but instead of warming the flue and creating draft, it vents out
of the draft hood at the rear of the heater. The spill switch then heats up, and in about 5 to 15
minutes shuts off all gas to the heater (shutting off the main burner and pilot). If a thermostat is used
on your heater, and the pilot shuts down sporadically, you may have a negative pressure situation.
Gas Line Install
The gas line must be installed in accordance with all local codes, if any; if not, follow ANSI
223.1 and the requirements listed below.

¥ The gas inlet is a male 3/8" NPT
