2. Visually inspect the venting system for proper size and horizontal pitch to determine if there is blockage, leakage, corrosion or other
deficiencies that could cause an unsafe condition.
3. If practical, close all building doors, windows and all doors between the
space in which the appliance remains connected to the common venting system
located and other spaces in the building. Turn on clothes dryers and any
appliances not connected to the common venting system. Turn on any exhaust
fans, such as range hoods and bathroom exhausts, at maximum speed. Do not
operate a summer exhaust fan. Close all fireplace dampers.
4. Place in operation the appliance being inspected. Follow the lighting
instructions. Adjust the thermostat so the appliance will operate continuously.
5. Test for spillage at the draft hood relief opening after 5 minutes of main
burner operation. Use the flame of a match or candle or smoke from a cigarette.
6. After it has been determined that each appliance remaining connected to
common venting system properly vents when tested as outlined, return doors,
windows, exhaust fans, fireplace dampers and any other gas burning appliance
to their previous condition of use.
7. Any improper operation of the common venting system should be corrected
to conform to the National Fuel Gas Code, ANSI Z223.1. When resizing any
portion of the common venting system, the system should approach the minimum size as determined using the appropriate tables in
Appendix G in the National Fuel Gas Code, ANSI Z 223.1.
