G. REMOVING A HEATER FROM A COMMON VENT SYSTEM
Do not install the 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 heater, follow the steps below.
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 doors between the
space in which the water heater remains connected to 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 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.
NOTE: DAMAGE TO THE HEATER CAUSED BY EXPOSURE TO CORROSIVE VAPORS IS NOT COVERED BY WARRANTY.
(Refer to the limited warranty for complete terms and conditions).
