Installation Information

Professional installation by a qualified gas or pool-equipment technician is required.

The installer must verify the installation elevation, gas-meter capacity, gas-line sizing, inlet and manifold gas pressure, electrical service, water flow, plumbing configuration, ventilation, combustion-air requirements, equipment clearances, and local code compliance.

This heater is factory configured for natural gas and elevations from 2,000 to 6,000 feet. It should not be installed outside that elevation range without confirming the correct Raypak configuration.

Do not connect this heater to propane gas unless a manufacturer-approved conversion is available and completed by a qualified professional.

Warranty Information

The Raypak 009222 is covered by a limited manufacturer warranty subject to Raypak’s current warranty terms, application, purchase channel, installation date, product registration, and professional-installation requirements.

Proof of purchase and professional installation documentation may be required.

Warranty coverage does not include damage caused by:

• Incorrect altitude configuration
• Improper gas pressure or gas-line sizing
• Incorrect fuel connection or unauthorized conversion
• Restricted or excessive water flow
• Poor or unbalanced water chemistry
• Scale, corrosion, or erosion
• Freezing
• Improper ventilation or venting
• Incorrect electrical installation
• Misuse or unauthorized modifications

Commercial use may receive different warranty coverage than a qualifying residential installation.
