This guide walks you through the step-by-step process of converting your EcoSmart Fire gas burner and control valve from LPG (propane) to natural gas. The conversion involves replacing orifices on both the control valve and the burner, and adjusting the air shutter.

Overview

The conversion process involves three main areas:

1. Control Valve — Replace the valve orifice and remove/reinstall the low-rate bypass tube.
2. Burner — Replace the burner orifice and adjust the air shutter.
3. Reconnection — Reconnect the burner flex-line and tighten all fittings securely.

Part 1: Control Valve Conversion

Step 1. Locate the Control Valve

Identify the control valve on your EcoSmart Fire burner assembly.
The control valve is the brass and white component connected to the gas line.

Step 2. Remove the Low-Rate Bypass Tube

Remove the low-rate bypass tube from the control valve.
Set it aside — you will re-install it after replacing the orifice.

Step 3. Remove the Valve Orifice

With a flat blade screwdriver, remove the valve orifice from the control valve.

Step 4. Replace with the Natural Gas Orifice

Replace with the natural gas orifice (identified by blue paint).

Step 5. Re-install the Low-Rate Bypass Tube

Re-install the low-rate bypass tube back onto the control valve.

Step 6. Remove the Flare Fitting Adaptor

Remove the flare fitting adaptor from the valve gas input valve.

Part 2: Burner Orifice Conversion

Step 1. Remove the Burner Flex-Line

Using adjustable wrenches, remove the burner flex-line from the burner orifice.

Step 2. Remove the Propane Burner Orifice

Remove the propane burner orifice from the burner assembly.

Step 3. Replace with the Natural Gas Burner Orifice

Replace with the natural gas orifice.

Step 4. Adjust the Air Shutter

Loosen the air shutter with a Phillips head screwdriver and fully close the air shutter.

Part 3: Reconnection

Connect the Burner Flex-Line

Connect the burner flex-line to the natural gas burner orifice and tighten securely.

Part 4: Conversion Complete

Your burner and control valve are now converted to natural gas.
