Why is proper pipe sizing and pressure essential for rooftop HVAC units?

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:

  • Operating Pressure: Small commercial rooftop units typically require a pressure of $5 \text{ to } 10 \text{ psi}$ to operate safely and at peak performance.
  • System Sizing: We calculate the pipe diameter based on total British Thermal Unit (BTU) demand, total pipe run length, and the required pressure drops.
  • Structural Supports: We place heavy-duty, engineered metal supports underneath the lines to safely distribute weight across your roof and prevent structural damage.

What safety codes and regulations apply to commercial rooftop gas lines in Alberta?

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.

To guarantee complete compliance, Scottco Gas Ltd. integrates these critical safety features into every setup:

  1. High-Pressure Testing: We perform rigorous air-pressure tests on all newly installed lines to verify that every joint is 100% leak-free before inspection.
  2. Outdoor Water Traps: We install physical drip legs (dirt pockets) to catch moisture and debris before they can enter and damage your heating equipment.
  3. Accessible Shut-Off Valves: We mount weather-resistant, clearly labeled manual shut-off valves at easily accessible points on the roof for emergency isolation.
  4. Protective Coatings: We paint all outdoor steel piping with rust-resistant coatings to shield the metal from southern Alberta’s damp, snow-heavy winter conditions.

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.
