Notes:

1

.

Table is based upon specific gravity of 0.60. Refer to the latest edition of the National Fuel Gas Code, Z223.1, unless superseded by local gas codes.

2

.

If more than one unit is served by the same main gas supply, consider the total gas input (cubic feet/hr.) and the total length when determining the appropriate gas

pipe size.

3

.

Obtain the Specific Gravity and BTU/Cu.Ft. from the gas company.

4

.

The following example demonstrates the considerations necessary when determining the actual pipe size:

Example: A 40' pipe run is needed to connect a unit with a 850 MBH furnace to a natural gas supply having a rating of 1,000 BTU/Cu.Ft. and a specific gravity of
0.60
Cu.Ft/Hour = Furnace MBH Input
Gas BTU/Cu.Ft. X Multiplier

Table 14, p. 44

Cu.Ft/Hour = 850
The above table indicates that a 2" pipe is required.
