This conversion must be made by a qualified service technician.
A Natural Gas to LPG conversion kit #HA-34-00178 is included with the DXV35 Fireplace. This
conversion kit is located within the Ziploc bag containing this Installation and Operating Instructions
Manual.
LP Conversion Kit #HA-34-00178 contains the following parts: One LP Pressure Regulator, One LP
Pilot Orifice Thimble, One Cap Orifice drill 1/16" (for rear burner) and One Cap Orifice drill #57 (for
front burner). Specifically, identify the Rear and Front Burner Cap Orifices. Use proper sized drill
bits' shaft ends to verify orifice sizes.
WARNING: IT IS OF THE UTMOST IMPORTANCE THAT THE CORRECT BURNER ORIFICE
BE INSTALLED FOR BOTH THE REAR AND FRONT BURNERS.
1. Turn off gas supply at the appliance service valve. Identify the Pressure Regulator on the Valve
Body, see Figure 18 on Page 36.
2. Using a ¼" flat blade screwdriver, remove 3 screws that secure the NG Pressure Regulator to the gas
valve body and remove NG Pressure Regulator as shown on PAGE 36. Identify the pressure
regulator spring that is located in the center of the black rubber gasket. Discard both the black rubber
gasket and spring.
3. Install the new LP Pressure Regular onto the gas valve body in the same position and orientation as
the NG Pressure Regulator you removed in Step 2, above. The LP Pressure Regulator can only be
f i r e - p a r t s . c o m
mounted in one position. Secure the LP Pressure Regulator in place using the 3 screws you removed
in Step 2. Tighten down using a ¼" flat blade screwdriver.
4. Remove both Rear and Front Burners. Locate and Identify the Rear Burner Orifice Spud and the
Front Burner Orifice Spud. Both Front and Rear Orifice Spuds are removed and installed using a ½"
deep well socket and ratchet.
5. Install Rear Burner Orifice #HA-33-00190 (1/16" drill) for the Rear Burner. Tighten down securely.
6. Install Front Burner Orifice #HA-33-00191 (#57 drill) for the Front Burner. Tighten down securely.
7. Install pilot orifice thimble #05-04-
00036 (.014") see Figure 15 for location.
Remove and install pilot hood with
7/16" open-end wrench. (Pilot orifice
thimble is located inside pilot hood
base).
8. Air Shutter Adjustments:
Rear Burner Flame
adjustment can be made using the Air
Shutter Control Knob located on the
Control Panel. Normally, for LPG
application, pull the Air Shutter control
Knob outward ½ inches. Depending on
venting configuration, the Air Shutter
Knob may need to be pulled further outward to provide more primary air.
Front Burner Flame: Air shutter adjustment must be made before installing the front burner inside
the firebox. Locate the rotary shutter and the setscrew. Using a Phillips Screw Driver, loosen the
setscrew and rotate the air shutter open 1/8 inches. Further adjustment to this shutter opening may
be necessary depending on the venting configuration and the flame color and glow effect desired.
NOTE: IF SOOT DEPOSITS LARGER THAN 1/2 INCHES DIAMETER ARE OBSERVED ON
ANY OF THE LOGS, THE FRONT AND/OR REAR AIR SHUTTER OPENINGS MUST BE
ENLARGED
