Installation Information

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

The installer must verify propane supply capacity, gas-line sizing, inlet and manifold gas pressure, electrical service, water flow, plumbing configuration, ventilation, combustion-air requirements, equipment clearances, elevation, and applicable local codes.

This heater is factory configured for propane gas and must not be connected to natural gas unless an approved manufacturer conversion is available and performed by a qualified professional.

• Incorrect fuel connection or conversion
• Restricted or excessive water flow
• Poor or unbalanced water chemistry
• Scale, corrosion, or erosion
• Freezing
• Improper venting
• Incorrect electrical installation
