Fireplace gas type conversion– NG to LPG- Orifice replacement

Flare Fireplaces can be easily converted from NG to LPG. When you place your order for a fireplace, include the gas type, NG or LPG so no conversion is necessary. The procedure below can be followed in the event a gas conversion is needed to be done.

Please note: only Authorized Flare Technicians will convert units from NG to LPN, therefore, gas conversion done by any unauthorized technicians will void the Flare Fireplace warranty. Contact Flare Fireplaces for details on your unit valve pressure setting (step 8).

Use the pictures below and Flare Install Manual to gather additional information. Gas conversion kit should be ordered from Flare Fireplaces prior to starting this procedure.

First of all, be sure there is no gas being fed to your unit. Technicians must also remove power to any added features. As a result, your unit is safe to open closed lines.

Optional – Lay the unit on its back to gain easy access to the burner orifice.

1. Confirm the correct specs of the unit needing the conversion. On that specification sheet, the correct orifice size and manifold pressure are listed for the specific unit. Spec sheets are located on the products page.

2. Remove burner Orifice. Be advised: Units 60″ and larger are equipped with 3 burners. All burner orifices will need to be changed in order to ensure safe operation of fireplace.

4. Replace Burner Orifice; while properly aligning threads when re-connecting. Finally, reinstall orifice housing into burner port and reconnect gas line.
