When comfort- heating appliances are installed in space where volume in cubic feet is less than one - twentieth the total maximum fuel input rate in B.T.U.H. of all appliances, combustion air shall be supplied from outdoors or from spaces freely connecting with outdoors. Exception: cooking appliances, refrigerators and dryers need not comply with above provisions. Amend Section 601 (c), Page 38 as follows: (c) In calculating free areas of grilles and louvers covering combustion air inlets, consideration shall be given to the blocking effect of louvers, grilles or screens protecting openings. Screens used shall not be smaller than 1/4 inch mesh and shall be readily accessible for cleaning. If the free area through a design of louver or grille is known, it should be used in calculating the size opening required to provide the free area specified. If the design and free area are not known, it shall be assumed that wood louvers will have 20 percent free area, metal louvers 50 percent free area and grilles will have 70 percent free areas. Amend Table No. 6 -A, Page 41 as follows: Move footnote at bottom of chart to top of the table. "This table shall not apply when Section 607 is used."

BOILER ROOM AIR SUPPLY Size the openings by using the formula, Area (Sq.Ft.) = CFM FPM Amount of Air Required (CFM) Combustion Air = Maximum BHP x 8 CFM /BHP Ventilation Air = Maximum BHP x 2 CFM /BHP or a total of 10 CFM BHP, up to 1,000 feet elevation. Add 3 percent more per 1,000 feet of added elevation where: CFM = cubic feet per minute BHP = boiler horsepower Note: for induced draft burners use same considerations as for gravity burners. -4- Amend Section 705, Page 44 as follows: Duct furnaces may be installed downstream from cooling coils or air wanhnrs if the heating element is made of corrosion - resistant material. Stainless steel, ceramic- coated steel, or an aluminum- coated steel in which the bond between the steel and the aluminum is an iron - aluminum alloy, are considered to be corrosion- resistant. Air washers operating with chilled water "hich deliver air below the dew point of the ambient air at the appliance are con- sidered as cooling systems. All duct furnaces shall be approved and carry the seal of the American Gas Association (A.G.A.). A plate indicating the approved clearances shall be mounted on the heater. Furnace shall have a condensate drain outlet in the bottom of the unit. Drain outlet shall discharge through a non - ferrous line to a floor drain, or other approved drain outlet. Each duct heater shall be equipped with a limit switch, having a top setting of 250 degrees. Wiring to gas valve shall be installed in such a manner that the gas valve will not open unless the fan circuit is energized. An air f M.' switch, suitable for system velocity, shall be located in the duct Ketween the fan and heater and incorporated in the gas valve wiring circuit to assure the flow of air through the heater before the main gas valve opens. Heaters shall be erected in accordance with their listing, and shall be safely and adequately supported with due consideration given to their height. Hangers, brackets and stands shall be non - combustible material. The ducts connected to duct furnaces shall have removable access panels on both the upstream and downstream sides of the furnace - minimum size of access panels 11" x 13 ". Reason for Change: Provide new requirements not now included in the code. Amend Section 706 (f), Page 45 as follows: Ducts for Blower -type Warm -air Furnace. Except as provided in Subsection (g) of this Section, circulating air supply for every fuel -fired blower -type uarm- air furnace shall be conducted into the blower housing from outside the furnace space by continuous airtight ducts. Exception: Non -fuel burning furnaces may take circulating air from within the furnace space; however, no source may be used as prohibited by Section 706 (g). Reason for Chancre: There is no need for this equipment as electric furnaces do not use combustion air. -5- Amend Section 706 (g) 5, Page 45 as follows: Exception. This shall not apply to: 1. Fireplaces, fireplace appliances, residential cooking appliances. ,nd residential clothes dryers installed within the room or space. 2. A gravity type comfort heating system. 3. A blower -type comfort heating system complying with the following requirements: Where the circulating air supply is taken from a room or space having a volume exceeding one cubic foot for each 10 B.T.U. fuel in put rate of all fuel - burning appliances therein. At least 75 percent of the conditioned air is discharged back into the same room or space.

No unvented fuel - burning room heater shall be installed in any Group D, H, or I Occupancy nor shall any such heater be installed in any building, whether as a new or as a replacement installation, unless permitted by this Section. Reason for Change: The retroactive provisions Would present a hardship on low- income housing and would be difficult to enforce. M Amend to add a proposed new section, 808, Page 54 as follows: "Indirect vented gas -fired heaters (Infra -Red) , not rcquirirg j an indivi._iu.-1 flue pipe, shall be installed only in spaces which have a nrininiwii infiltration of one air change per hour for general ventilation.

Infra -red heaters, equipped with a vent outlet shall be vented to the outside of the enclosing building. Listed vent cap shall be increased one size larger than the vent pipe, using an approved reducer. Method of venting shall conform to the manufacturer's recommendations." Reason for Change: To establish a minimum combustion air standard and a means of exhausting products of combustion as a life safety measure trhen infra -red heaters are used in enclosed spaces.

Enclosure re�,ire-<nts are from the point of penetration to the outside air %.!iLh :i _ible two -hour rated enclosure in Type 1 and Type 11 (r,iason_ry non- co-rnbust i 6l el construction and one -hour rated enclosures in all other types. Exception: Single -story buildings and 1 Occupancies do not require enclosures. 1. The shaft or enclosure shall be separated from the duct by a minimum of three inches and a maximum of twelve inches and this area shall he ventilated to the outside air. Such enclosure shall be sealed at the point of penetration. The shaft or enclosure shall be used exclusively to enclose a single grease exhaust duct system.
