Installation Notes

This heater must be installed by a qualified pool professional, licensed gas technician, or licensed contractor as required by local code. Proper installation requires correct natural gas supply sizing, gas pressure verification, electrical wiring, bonding, grounding, water flow verification, plumbing layout, combustion air, and venting where required.

Before installation, confirm the site uses natural gas and that the gas supply can support a 266,000 BTU heater. Also confirm whether the project requires ASME-certified heater construction.

Water chemistry must be maintained within recommended ranges to protect the copper heat exchanger and preserve heater performance. Improper water balance, poor flow, incorrect gas pressure, restricted venting, or improper installation can damage the heater and may void warranty coverage.
