General Information
This gas conversion kit contains the necessary components for field
conversion of an approved Montigo fireplace from Natural Gas (NG)
to Liquid Propane (LP). This kit is approved for use with the top and
rear vent versions of the following manufactured (mobile) home
models:
 DFSP DXFS
 DFSP-MH DXFS-MH
A manufactured (mobile) home OEM installation in the United States
must conform with the Manufactured Home Construction and Safety
Standard, Title 24 CFR, Part 3280, or, when such a standard is not
applicable, the Standard for Manufactured Home Installations, ANSI
/ NCSBCS A225.1. In Canada, the installation must conform to the
Standard for Gas Equipped Recreational Vehicles and Mobile Hous-
ing, CSA Z240.4.
The installation of this unit must also conform with local codes or, in
the absence of local codes, with the American National Fuel Gas
WARNING!
This conversion kit shall be installed by a qualified service
agency in accordance with the manufacturer's instructions
and all applicable codes and requirements of the authority
having jurisdiction. If the information in these instructions
is not followed exactly, a fire, explosion or production of
carbon monoxide may result causing property damage,
personal injury or loss of life. The qualified service agency
is responsible for the proper installation of this kit. The
installation is not proper and complete until the operation
of the converted appliance is checked as specified in the
manufacturer's instructions supplied with this kit.

Gas Conversion Instructions
The pilot orifice has a small marking on the side to indicate its
size and which gas it is for. Ensure that you have the correct
orifice in the pilot hood. (See figure 3.)
Conversion
CAUTION - Before you begin:
1. Shut off gas at the shut-off valve.
2. Remove the glass door as shown in the installation instructions
and remove the logs.
Front Burner:
3. On the DXFS and DFSP models, remove the clip that holds the
left end of the burner tube on the burner bracket, remove the two
screws securing the flame shaper, then lift the burner out of the
bracket. See Figure 1.
Figure 1. Removing the burner tube and replacing the orifice.
4. Carefully slide the front burner tube off the orifice (located inside
the right end of the burner). See Figure 1.
Replace the old orifice with the new orifice marked 'F' (front)
from this kit. Tighten the new orifice until it is snug to prevent any
leaks. Refer to the conversion kit for orifice sizes.
5. Remove the front log rest and set it aside.
Rear Burner:
6. Remove the clip that secures the rear burner to the firebox.
Slide the rear burner tube off the orifice on the right-hand side.
Unscrew the old orifice from the orifice holder, and replace it with
the new orifice from this kit marked 'R' (rear). Tighten the new
orifice until it is snug to prevent any leaks.
Pilot Assembly:
7. While you have the rear burner removed, unscrew the pilot hood
counter-clockwise and remove the pilot orifice. Replace it with
the new orifice supplied with this kit. Replace the pilot hood and
tighten it clockwise, ensuring that it is back in its original position.
(See figure 2.)

8. Re-install the new rear burner marked 'R' (rear) from this kit,
and replace the clip and ensure that the pilot burner is correctly
positioned. The pilot hood should aligned with the burner tube as
shown in Figure 4.
9. Re-install the flame shaper and front log rest.
10. Re-install the new front burner marked 'F' (front) from this kit,
and replace the clip.

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.
