proceeding with the conversion.
2) Remove the door, ceramic logs, log tray and burner (see page 43 in the manual).
3) Remove the valve tray (see pages 43 in the manual).
4) Replace with desired valve tray (installation is the reverse of removal).
5) Verify the input of the converted appliance by checking the orifice size with the size specified on
the ratings labels found on pages 50 & 56 of the manual.
6) Replace burner, log tray, ceramic logs and door.
7) Leak test the appliance, with a soapy water solution, prior to placing the unit into operation.

See pages 30, 33 & 55 of the manual for proper pilot and burner flame pictorials.
Fill out and attach the fuel conversion label provided in the kit then apply label over top of existing
ratings label.
All valves have been pre-set and certified for installation at elevations from 0 – 2000 feet (1 – 608 m)
above sea level.
When installing this unit at higher elevations, it is necessary to decrease the input rating by replacing
the existing burner orifice with a smaller size for installations over 2000 feet (608 m). The appliances
input should be reduced 4% for each additional 1000 feet (305 m) above sea level. For the USA, de-
rate the unit from sea level according to the gas installation code.
