At the time of removal of an existing boiler, the follow-

ing steps shall be followed with each appliance

remaining connected to the common venting system

placed in operation, while the other appliances remain-

ing 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 make sure 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 com-

mon venting system are located and other spaces

of the building. Turn on clothes dryers and any

appliance not connected to the common venting

system. Turn on any exhaust fans, such as range

hoods and bathroom exhausts, so they will oper-

ate at maximum speed. Do not operate a summer

exhaust fan. Close fireplace dampers.

4. Place in operation the appliance being inspected.

Follow the lighting instructions. Adjust thermostat

so appliance will operate continuously.

5. Test for spillage at the drafthood relief opening

after 5 minutes of main burner operation. Use the

flame of a match or candle, or smoke from a ciga-

rette, cigar or pipe to visually check spillage.

6. After it has been determined that each appliance

remaining connected to the common venting sys-

tem properly vents when tested as outlined above,

return doors, windows, exhaust fans, fireplace

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 that the installation

conforms with the latest edition of the National

Fuel Gas Code, ANSI Z223.1. When resizing any

portion of the common venting system, the com-

mon venting system should be resized to

approach the minimum size as determined using

the appropriate tables in the National Fuel Gas

Code, ANSI Z 223.1 and CSA - B149.

Vent Damper Installation

Location

The vent damper supplied with each boiler must be

located in the vent so that it serves only the appliance

for which it is intended.

If improperly installed, a hazardous condition, such as

an explosion or carbon monoxide poisoning, could

result. Make certain that it is mounted in an accessible

location at least 6 in. (152.4 mm) from any combustible

material or the heat exchanger and that the position

indicator is in a visible location.

The vent damper must be installed at the appliance

drafthood, and without modification of the drafthood.

To connect the vent damper wiring to the boiler wiring,

connect the damper circuit plug to the boiler circuit

plug.
