Regulating gas pressure at the valve is what keeps a propane fireplace burning at its intended output, and this component handles that job in SIT Nova systems. The Enviro LP Turn Down Regulator Plate (part 50-489, also listed as 50489) is a genuine Enviro replacement for the regulator plate used on propane-fired Enviro appliances.

Purpose

This plate sets the turn-down regulation for SIT Propane systems with a 2.9 in. to 10 in. regulator face, working with the SIT 820 Series valve to provide 50% turndown capability.

Key Benefits

• Direct-fit replacement for the original SIT Nova regulator plate — no modification needed
• Restores proper gas pressure regulation and turn-down function
• Genuine Enviro part, not an aftermarket copy
• Matches SIT 907.204 specification for consistent performance

Specifications

Other Notes

Because this plate is part of the gas pressure regulation path, installation should be performed by a licensed gas technician in accordance with local codes.

When replacing this regulator plate, it's worth having a technician inspect the associated SIT 820 Series valve and any related gas fittings for wear at the same time.
