Gas Conversion Kit for DXFS/DFSP-MH models
Main Gas Control Regulator Screw:
11. The stove models use the Honeywell Hi/Lo gas control valve,
which has a removable regulator screw. The kit will include a
new regulator screw, the red screw is for Propane (LP) and the
blue screw is for Natural Gas (NG). It is located in the middle of
the hi/lo knob, replace it, and install the new regulator screw.
Gas Conversion Instructions
Checking the Gas Pressure
To check the Inlet and Manifold gas pressures, a Water Column Pres-
sure Gauge with 5/16" dia. tubing can be used. Make sure the gas
shut-off valve is closed, then attach the gauge to the Manifold Pres-
sure Test Connection by loosening the screw shown in Figure 6. The
tubing must be tight in the connection to prevent gas leaks. Measure
the Manifold Pressure and compare the value against the chart below.
Turn off the fireplace and close the shutoff valve. Remove the test
Figure 6. Honeywell VS8520E gas valve.
Natural Gas Liquid Propane
Manifold Pressure (min.) 3.5" W.C. 10" W.C.
Inlet Pressure (min.- max.) 5.5" - 14" W.C. 11" - 14" W.C.
" W.C. = inches water column
gauge. Re-tighten the test connection screw to prevent gas leakage.
Repeat the procedure for the Inlet Pressure.
If the pressure readings are not within the limits set out, contact the
factory. If the pressure readings are correct, ensure that both test con-
nection screws are tightened securely, to prevent a gas leak.
Pilot Burner Adjustment
1. Locate Pilot Adjustment Screw. (See figure 6)
2. Adjust pilot screw to provide properly sized flame as shown in fig-
ure 7). To increasethe flame, turn the screw counterclockwise. To
decrease the flame, turn it clockwise. The flame should impinge
on the thermocouple and thermopile.
3. After installing or servicing, leak test using a soap solution with
main burner turned on. Coat pipe and tubing joints, gasket etc.
with soap solution. Bubbles indicate leaks. Tighten any areas
where the bubbles appear until the bubbling stops completely.
Figure 7. Pilot Burner
12. The label (part no. XL0201) indicating that the fireplace has been
converted for use with a different gas must be placed on the
fireplace rating plate over top of the existing fuel type chart.
The label (part no. XL0200) indicating who converted the ap-
pliance must be filled out and placed on the base pan, directly
under the gas valve.
Also place the label indicating that the control valve has been
converted for use with a different gas.
