Engineering and Functional Features

This model includes a factory-installed flammable vapor ignition-resistant (FVIR) system, maintenance-reducing powered anode rod, and a brass drain valve. Its integrated self-diagnostic gas valve provides LED fault codes for faster troubleshooting. The power vent blower operates on standard 120V input and features quiet operation and pressure sensing for safety lockout protection.

All wetted tank components are glass-lined to prevent corrosion, and dielectric heat traps are included to reduce standby losses. This unit is certified for low NOx operation in compliance with SCAQMD Rule 1121 emissions regulations.

Installation Notes

The PROG40S-32P-RH67-PV requires both LP gas supply and 120V electrical power. Proper vent routing with correct pitch and termination clearances must be verified per installation manual. Horizontal vent runs must not exceed manufacturer-specified length based on pipe diameter and elbow use. Ensure condensate management and local code compliance during placement.

Recommended for residential replacement and new construction applications where atmospheric venting is impractical. Professional installation is advised due to venting and gas fitting complexity.
