Title: Pool Heater Gas Sizing: Heat Without Headaches
Summary: Your heater doesn’t run on vibes—it runs on pressure and volume. In this episode we define what “good” looks like under IFGC §402 / NFPA 54 so owners and builders can communicate clearly and avoid the lockout blame game. No DIY here—this is the big picture, outcomes, and documentation you should expect from a licensed pro.

Safety note: This episode is for education and coordination; all gas work must be performed by licensed professionals under the Authority Having Jurisdiction (AHJ) and per applicable codes and manufacturer instructions.

Licensing: Wisconsin HVAC Contractor #1543940 · Florida CPC1460695 · Texas TICL 1350 / RAIL 635643. Services are provided under the appropriate license in the state of service.

What you’ll learn

• How to align scope to code (IFGC §402 / NFPA 54)
• The five code-driven checkpoints that keep heaters online
• Why meters, regulators, and pipe size matter more than “bad boards”
• How a simple startup manometer log ends most arguments

Big-picture checklist (non-DIY)

1. Total connected load listed (current + near-future)
2. Equivalent length and route sketched
3. Named table & delivery pressure (code edition, allowable drop)
4. Utility meter capacity & regulator setpoints confirmed in writing
5. Manometer readings at startup: static & at-fire with photos

Codes & references

• IFGC §402 — Gas Piping Sizing (tables/equations, pressure/drop assumptions)
• NFPA 54 / ANSI Z223.1 — National Fuel Gas Code (parallel principles)
• Manufacturer heater manual for required inlet/outlet pressures
