Pros & Cons

Pros

  • Manual includes commercial installation, controls, wiring, venting, startup, maintenance, and parts sections.
  • Covers pool heater Type P configurations alongside hydronic and domestic hot water variants.
  • Useful for large commercial pool equipment rooms.

Watchouts

  • Commercial combustion, venting, gas-train, and code requirements are materially more complex than residential heaters.
  • Confirm Type P pool configuration and exact model before using specs.
  • Public spec page should not replace engineered sizing or licensed installation review.

Error Codes & Troubleshooting

Ignition Lockout (PIM LED + VERSA IC Display)
On single trial-for-ignition models the PIM enters ignition lockout immediately; multi-trial models run an interpurge delay first. The PIM LED indicates the fault and the VERSA IC display states "Ignition Lockout." Check gas supply, spark, and wiring. This manual does not document a numbered flash-code table - read the exact fault text from the VERSA IC display.
