Gas Conversion

In order to change a fireplace from one gas source to the other, request a gas conversion
kit.
This can only be performed by technicians with a specific authorization to change these
components. Actual change must be done by the authorized technician. Not all installers are
authorized to provide gas conversion services.
Gas conversion steps:
1. Change the burner orifice
2. Change the pilot orifice
3. Adjust the venturi
Adjust the BTU in the valve. See Mertik Maxitrol appendix B for direction

Burner

All fireplaces can be equipped with burners/ semi burners/double burners. They can all be used
with NG or LPG.
A standard burner is easily converted to a semi burner. The procedure is the same as
replacing a standard burner with another burner. No special materials or tools are
required.

Burner Inspection

Burner comes complete with all the necessary parts assembled, including: venturi, nozzle, pilot,
thermocouple and spark plug. Parts are pre-set for the specific gas type (natural/propane) and no
field adjustments are necessary.
During installation the burner and its accessories must be inspected for cleanliness and
completeness. Do NOT disassemble the components.

Burner Maintenance

Remove the media and vacuum all debris from firebox, burner and grill area at least once a year
(quarterly for commercial installations).
When operating the flame from the burner should be visually checked. It should appear blue and
yellow and candle-like in appearance.
