H. REMOVING A WATER HEATER FROM A COMMON VENT SYSTEM
Do not install the water heater into a common vent with any other appliance. This will cause flue gas spillage or appliance malfunction,
resulting in possible substantial property damage, severe personal injury, or death.
Failure to follow all instructions can result in flue gas spillage and carbon monoxide emissions, causing severe personal injury or death.
When removing an existing water heater, the following steps must be followed.
1. Seal any unused openings in the common venting system.
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 common
venting system 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 so the installation conforms to the National Fuel Gas
Code, ANSI Z223.1. When resizing any portion of the common venting system, the common venting system should be resized to
approach the minimum size as determined using the appropriate tables in Appendix G in the National Fuel Gas Code, ANSI Z 223.1.
