<strong>Appliance</strong>s may be connected to the fuel gas piping by means<br />
of an approved listed quick-disconnect device with an approved<br />
shut-off valve connected to the rigid gas piping.<br />
16. REQUIRED GAS SUPPLY: <strong>Gas</strong> piping shall be sized by CFH.<br />
To obtain the cubic-feet-per-hour of gas required, divide the<br />
input of appliances by the average Btu heating value per cubic<br />
foot of the gas. See Table X, Pages 87-90 or consult <strong>Questar</strong><br />
<strong>Gas</strong> Company <strong>for</strong> the average Btu per cubic foot if it is not<br />
known.<br />
Example: 100,000 Btu/h rated furnace installed in an area with<br />
890 Btu per cubic foot.<br />
100,000 = 112 CFH<br />
890<br />
