III. Installation
A.
VENT GUIDELINES DUE TO REMOVAL OF AN
EXISTING WATER HEATER
For installations not involving the replacment of an
existing water heater, proceed to step B.
When an existing water heater is removed from
a common venting system, the common venting
system is likely to be too large proper venting of the
remaining appliances. At the time of removal of an
existing water heater, the following steps shall be
followed with each appliance remaining connected
to the common venting sytem placed in operation,
while the other appliances remaining connected to
the common venting system are not in operation:
1. Seal any unused openings in the common venting
system.
2. Visually inspect the venting system for proper size and
horizontal pitch and determine there is no blockage or
restriction, leakage, corrosion, and other deficiencies
which could cause an unsafe condition.
3. Insofar as is practical, close all building doors and
windows and all doors between the space in which
the appliances remaining connected to the common
venting system are located and other spaces of the
building. Turn on clothes dryers and any appliance
not connected to the common ventings system.
Turn on any exhaust fans, such as range-hoods and
bathroom exhausts, so they will operate at maximum
speed. do not operate a summer exhaust fan. Close
fireplace dampers.
4. Place in operation the appliance being inspected.
Follow the Lighting (or Operating) Instructions. Adjust
thermostat so appliance will operate continuously.
5. Test for Spillage at the draft hood relief opening
after five (5) minutes of main burner operation. Use
the flmae of a match or candle, or smoke from a
cigarette, cigar, or pipe.
6. After it has been determined that each appliance
remaining connected to the common venting system
properly vents when tested as outlined above, return
doors, windows, exhaust fants, fire place dampers
and any other gas burning appliance to their previous
conditions of use.
7. Any improper operation of the common venting
system should be corrected so teh installation
conforms with the National Fuel Gas Code, NFPA
54/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
Part II in the National Fuel Gas Code, NFPA 54/ANSI
Z223.1.
B. VENTING
WARNING
Improper venting may result in property damage
and the release of flue gasses which contain
deadly carbon monoxide (CO) into the building,
which can cause severe personal injury and/or
death.
