1. The | gas | line should | be | a | separate line direct | from | ||
the | meter unless | the | existing | gas | line is | of | ||
sufficient | capacity. | Verify | pipe | size | with your | gas | ||
supplier. |
|
|
|
|
|
|
|
2.Use new, properly threaded black iron pipe free
from | chips. | If tubing is | used, | make | sure the | ends |
are | square, deburred and | clean. | All | tubing | bends | |
must be smooth and without deformation. | Avoid | |||||
flexible gas | connections. | Internal | diameter of | |||
flexible gas lines may not provide | appliance | with | ||||
proper volume of gas. |
|
|
|
|
3.Install a manual main gas shutoff valve at the units
| gas | inlet, | outside | of the appliance | and | before | the | |||||
| gas | valve. | Install | a | union | at the appliance | gas | |||||
