Appendix CC-M-2
Sizing and Capacities of Gas Piping

In order to determine the size of piping to be used in designing a gas piping system, the following factors must be considered:
(1) Allowable loss in pressure from the commercial coach gas supply connection to appliance.
(2) Maximum gas consumption to be provided.
(3) Length of piping and number of fittings.
(4) Specific gravity of the gas.
(5) Diversity factor.
DESCRIPTION OF TABLES

(a) The quantity of gas to be provided at each outlet shall be determined directly from the manufacturer's Btu input rating of the appliance that will be installed.
(b) Capacities for gas at low pressures (0.5 psig or less) in thousands of BTUH of 0.60 specific gravity gas for different sizes and lengths are shown in Table CC-M-3 for iron pipe or equivalent rigid pipe and for semirigid tubing. Table CC-M-3 is based upon a pressure drop of 0.5 inch water column. In using these Tables no additional allowance is necessary for an ordinary number of fittings.

(c) Capacities in thousands of Btu per hour of undiluted liquefied petroleum gases based on a pressure drop of 0.5 inch water column for different sizes and lengths are shown in Table CC-M-3 for iron pipe or equivalent rigid pipe and for semirigid tubing. In using these Tables, no additional allowance is necessary for an ordinary number of fittings.
(d) For any gas piping system, for special gas appliances or for conditions other than those covered by Table CC-M-3 such as longer runs, greater gas demands, or greater pressure drops, the size of each gas piping system shall be determined by standard engineering methods acceptable to the department.
USE OF CAPACITY TABLES

To determine the size of each section of gas piping in a system within the range of the capacity tables, proceed as follows:
(a) Determine the gas demand of each appliance to be attached to the piping system. When Table CC-M-3 is to be used to select the piping size, calculate the gas demand in terms of thousands of BTUH for each piping system outlet.

(b) Measure the length of piping from the gas supply connection, to the most remote outlet in the commercial coach.
(c) In the appropriate capacity table, select the column showing the measured length or the next longer length if the table does not give the exact length. This is the only length used in determining the size of any section of gas piping.
(d) Use this same vertical column to locate all gas demand figures for this particular system of piping.
(e) Starting at the most remote outlet, find in the vertical column just selected the gas demand for that outlet. If the exact figure or demand is not shown, choose the next larger figure below in the column.
(f) Opposite this demand figure, in the first column at the left, will be found the correct size of gas piping.
(g) Using this same vertical column, proceed in a similar manner for each outlet and each section of gas piping. For each section of piping, determine the total gas demand supplied by that section. Where gas piping sections serve both heating and cooling equipment and the installation prevents both units from operating simultaneously, only the larger of the two demand loads need be used in sizing these sections.
EXAMPLE OF PIPING SYSTEM DESIGN:
Determine the required pipe size of each section and outlet of the piping system shown in Exhibit 1, with a designated pressure drop of 0.05 inch water column.


SOLUTION
(1) The length of pipe from the gas supply inlet to the most remote outlet (a) is 60 feet. This is the only distance used.
(2) Using the column marked 60 feet in the Table:
Outlet A, supplying 30,000 BTUH, requires 3 /8 " iron pipe.
Outlet B, supplying 3,000 BTUH, requires 1 /4 " iron pipe.
Section 1, supplying outlets A and B, or 33,000 BTUH, requires 3 /8 " iron pipe.
Outlet C, supplying 73,000 BTUH, requires 3 /4 " iron pipe
Section 2, supplying outlets A, B, and C, or 106,000 BTUH, requires 3 /4 " iron pipe.
Outlet D, supplying 136,000 BTUH requires 3 /4 inch pipe.
Section 3, supplying outlets A, B, C, and D, or 242,000 BTUH, requires 1 " iron pipe.

Panels shall be applied to wood framing members using water
resistant, non-hard setting adhesive. Adhesive shall be
applied to the face of all framing members except locations
where panel edges fall beneath applied moldings. Panels may

Note: Fasteners, if necessary, shall be used only in
locations where they will be covered by applied moldings,
and shall be used on not more than two adjacent edges. No
other interior fasteners, or fixtures, other than required
functional plumbing fixtures shall penetrate the face of
the panel. Openings for these plumbing fixtures must be
sealed with caulk.
C. Corners and
Edges: All corners and edges must be caulked or sealed against
moisture penetration. A non-hard setting sealant material
must be used with applied moldings. Fastening of moldings
to framing shall not be greater than 6 " o.c.
