Gas Conversion Instructions
Pilot Assembly:
Ember Burner:
3. Disconnect the 1/4" tubing from the fitting on the underside of
the pan base. Disconnect the fitting from the inlet side of the gas
control valve.
4. Spin off the coupling just above the tee. The gas valve assembly
will drop out of the way, allowing access to the coupling.
5. Uncrew the coupling assembly from the pan base. The orifice is
located at top end of coupling. Unscrew it and install the orifice
from the package marked 'Ember Burner Orifice' in this kit to
convert to the new gas.
Main Gas Control Regulator:
6. Before re-assembling the gas tubing, the gas valve must be
converted to operate on the new gas. Change the regulator on
the SIT Nova gas valve.
Note: This fireplace has a flip-over regulator, and needs no extra
parts to convert.
7. To convert from one gas to another, simply unscrew the regula-
tor, turn over and reinstall. One face of regulator is stamped NG,
the other is marked LPG. The outer face of screw will indicate
the correct gas.
8. Reassemble the gas fittings.
