Specifications

Propane / LP Configuration

The SR200LP is specifically designed for propane gas.

Pentair offers different Max-E-Therm models depending on fuel type:

Always verify the available fuel supply before ordering.

84% Thermal Efficiency

The SR200LP is rated at approximately 84% thermal efficiency, helping provide strong heating performance while maintaining efficient fuel use.

This makes it a solid option for pool and spa owners who want dependable gas heating in a compact heater design.

Water Flow Requirements

The Max-E-Therm 200 is designed to operate within a water-flow range of approximately:

• Minimum: 20 GPM
• Maximum: 120 GPM

Proper flow is critical for safe and efficient heater operation.

If system flow exceeds the recommended maximum, a properly designed bypass may be required.

Smart Heater Bypass Compatibility

The SR200LP can be paired with a compatible Pentair Smart Heater Bypass Valve Kit.

A bypass can help reduce unnecessary hydraulic resistance when heating is not required, especially on systems using variable-speed pumps.

This can improve overall circulation efficiency when the heater is idle.

Digital Controls

The Max-E-Therm features a user-friendly digital control panel that allows adjustment of:

• Pool temperature
• Spa temperature
• Operating mode
• Heater status
• Diagnostic information

The controls are designed to make everyday operation simple for homeowners and service professionals.

Durable Dura-Glas™ Enclosure

The Max-E-Therm uses a rust-resistant Dura-Glas enclosure rather than a traditional all-metal cabinet.

This helps reduce concerns related to exterior corrosion in outdoor pool environments.

Installation Requirements

The SR200LP is a gas-fired appliance and should be installed by a qualified pool professional or licensed gas technician.

Before ordering, confirm:

• Propane gas supply
• Gas-line sizing
• Gas pressure
• Electrical supply
• Pool plumbing size
• Water flow rate
• Heater clearances
• Venting requirements
• Combustion air requirements
• Local building and fuel-gas codes

Improper installation can cause equipment damage and serious safety hazards.

Indoor Installation

For indoor installations, proper venting and combustion-air requirements must be followed carefully.

A qualified installer should verify:

• Vent size
• Vent material
• Vent routing
• Combustion-air supply
• Required clearances
• Local mechanical code requirements
