CONVERSION KIT INSTRUCTIONS
CONVERT THE GAS CONTROL VALVE:
Follow stepper motor pressure regulator instruction sheet included with conversion
kit to convert gas valve. (LP or NAT marked on stepper motor pressure
regulator).
COMPLETE THE CONVERSION:
1. Adjust front burner venturi setting by loosening screw, adjusting cap and
retightening screw. NAT: 100% closed / LP: 5/8" (16mm) open
2. Re-install burner assemblies into fireplace, checking to ensure burner venturis
are properly seated over burner orifices.
3. Back (main) burner venturi adjustment handle is attached to underside of
control board. Access through lower grill opening. Loosen wing nuts, adjust
as necessary, pulling handle forward to open, pushing backwards to close.
Tighten wing nuts.
NAT: 1/8" (3mm) open - handle pushed back
LP: 5/8" (16mm) open - handle pulled forward
Venturi may need further adjustment, depending on venting configuration.
4. Adjust combustion air intake shield*.
IF CONVERTING TO LP GAS:
5.
IF CONVERTING TO NAT GAS: Install baffle shield included with kit
6. Re-install pilot shield.
7. Reinstall any light kit components if previously removed.
8. Re-install ember refractory and logs*.
9. Turn on gas and electrical supplies.
10. Light fireplace*. Check for leaks at all connections with soapy water, whether
field or factory made.
11. Test inlet pressure, referring to page 13 for proper testing procedures. Chart
below states proper pressure readings. Visually check pilot flame. Flame
should envelope top of flame sensor and extend onto burner far enough for
