What it is
Gas line installation Gas line installation is the process of running new gas piping to supply an appliance such as a range, water heater, furnace, or outdoor fire feature, including pressure testing before the line is put into service.
Gas line work in Denver requires a licensed contractor and a permit with inspection, because a poorly sealed connection puts the whole house at risk.
Sizing is about total load, not just the new appliance
Every appliance on the meter shares the supply. Adding a tankless heater or a high-BTU range to a line already carrying a furnace and a dryer can starve everything on it. Correct work starts with a load calculation and a pipe sizing table, not a guess at the branch.
- Load calculation across every appliance on the meter
- Correct pipe diameter over the actual run length
- Sediment trap and shutoff at each appliance
- Pressure test and inspection before the gas is turned on
When you need new gas line work
