G. Prevent Combustion Air Contamination
Install intake air piping for the heater as described in the Venting Section, this manual. Do not terminate exhaust in locations that can allow
contamination of intake air.
Ensure that the intake air will not contain any of the contaminants in Table 6. Contaminated air will damage the heater, resulting in possible
substantial property damage, severe personal injury, or death. For example, do not pipe intake air near a swimming pool or laundry facilities.
These areas always contain contaminants.

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.)
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
deciencies 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
replace dampers.
4. Place in operation the appliance being inspected. Follow the lighting
H. Removing a Heater from a Common Vent System
Do not install the heater into a common vent with any other
appliance. This will cause ue gas spillage or appliance malfunction,
resulting in possible substantial property damage, severe personal
injury, or death.
Failure to follow all instructions can result in ue gas spillage and
carbon monoxide emissions, causing severe personal injury or death.

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 ame of a match or candle or smoke
from a cigarette.
6. After it has been determined that each appliance remaining connected to the common venting system properly vents when tested as
outlined, return doors, windows, exhaust fans, replace dampers, and any other gas burning appliances 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 of ANSI Z223.1.
