input rating of all equip ent located in the enclosure. The free area ust be no less than the

su of the areas of all vent connectors in the confined space.

6. In calculating free area using louvers, grilles or screens for the above, consideration

shall be given to their blocking effect. Screens used shall not be s aller than 1/4 inch esh.

If the free area through a design of louver or grill is known, it should be used in calculating

the size opening required to provide the free area specified. If the design and free area is

not known, it ay be assu ed that wood louvers will have 20-25% free area and etal

louvers and grilles will have 60-75% free area. Louvers and grilles should be fixed in the open

position or interlocked with the boiler so they are opened auto atically during the boiler

operation.

ENT SYSTEM MODIFICATION

When an existing boiler is re oved fro a co on venting syste , the co on venting

syste is likely to be too large for the proper venting of the appliances re ained connected

to it. If this situation occurs, the following test procedure ust be followed:

At the ti e of re oval of an existing boiler, the following steps shall be followed with

each appliance re aining connected to the co on venting syste placed in operation,

while the other appliances re aining connected to the co on venting syste are not in

operation.

A. Seal any unused openings in the co on venting syste .

B. Visually inspect the venting syste for proper size and horizontal pitch and deter ine

there is no blockage or restriction, leakage, corrosion and other deficiencies which could

cause an unsafe condition.

C. Insofar as is practical, close all building doors and windows and all doors between

the space in which the appliances re aining connected to the co on venting syste are

located and other spaces in the building. Turn on clothes dryers and any appliance not

connected to the co on venting syste . Turn on any exhaust fans, such as range hoods

and bathroo exhausts, so they will operate at axi u speed. Do not operate a su er

exhaust fan. Close fireplace da per.

D. Place in operation the appliance being inspected. Follow the lighting instructions.

Adjust ther ostat so appliance will operate continuously.

E. Test for spillage at the draft hood relief opening after 5 inutes of ain burner

operation. Use the fla e of a atch or candle, or s oke fro a cigarette, cigar or pipe.

F. After it has been deter ined that each appliance re aining connected to the co on

venting syste properly vents when tested as outlined above, return doors, windows,

exhaust fans, fireplace da pers and any other gas burning appliance to their previous

conditions of use.

G. Any i proper operation of the co on venting syste should be corrected so the

installation confor s with the latest revision of the National Fuel Gas Code, ANSI Z223.1.

When resizing any portion of the co on venting syste , the co on venting syste

should be resized to approach the ini u size as deter ined using the appropriate tables

in appendix G in the latest revision of the National Gas Fuel Code, ANSI Z223.1.
