Proper pipe sizing and system pressure are critical to prevent fuel starvation, which causes rooftop HVAC units to work harder, lose efficiency, or fail entirely during cold weather. If gas line pipes are too small, they cannot deliver the volume of natural gas required when multiple heating units kick in at the same time.
At Scottco Gas Ltd., we perform precise calculations to ensure your small commercial system delivers the necessary pressure:

Commercial rooftop gas lines in Alberta must comply with the CSA B149.1 Natural Gas and Propane Installation Code and local municipal safety bylaws. Every new installation or major modification requires a valid municipal gas permit and must pass a physical pressure test witnessed by a safety codes officer.

A standard commercial rooftop gas line installation takes two to four business days to complete. This timeline includes planning the pipe routing, installing the physical lines on engineered supports, performing pressure testing, and hosting the municipal safety codes officer for the final permit inspection.
Every commercial gas line installation requires a commercial gas permit issued by the City of Calgary or the appropriate local authority. Scottco Gas Ltd. manages this entire administrative process for you, submitting detailed plans to ensure the system is approved quickly and without delay.
We protect rooftop lines by using heavy-duty steel piping finished with a rust-resistant paint barrier. Additionally, we secure the lines on specialized, weather-tolerant structural blocks that allow the pipe to safely expand and contract during extreme temperature swings, Chinooks, and heavy snow loads.
Small commercial rooftop HVAC units typically require a delivery pressure range of 5 to 10 psi . Our certified gas fitters verify the manufacturer requirements for your specific HVAC units and configure the regulators to provide exactly this pressure.
Yes, we can design a single, centralized main trunk line that branches off to feed multiple rooftop heaters. We carefully calculate the combined BTU requirements to ensure that even when every unit is running at maximum capacity during a cold winter day, the system maintains a steady pressure of 5 to 10 psi across all units.
