CONVERSION INSTRUCTIONS FROM (LP) PROPANE GAS TO NATURAL GAS

1. Make sure gas supply to furnace is off prior to conversion and disconnect electrical power to unit.

2. Open brass union located between the gas valve and burner box. Re-

move the 4 mounting screws securing manifold plate to the burner box.

Remove the top 2 screws holding the burner box top in place and then

remove the 1 screw holding the end of the manifold pipe in place. Grasp

union and remove manifold pipe.

3. Remove (1) LP gas main burner orifice marked 55 for DV-20E or (2) LP

gas main burner orifices marked 55 for DV-40E located in the manifold

pipe and replace with (1) Natural gas main burner orifice marked 44 for

DV-20E or (2) Natural gas main burner orifices marked 44 for DV-40E

supplied in conversion kit.

4. Replace manifold pipe being sure to locate orifice(s) in the end of the burner. Secure the manifold and top burner box cover in

place using the screws earlier removed. Reconnect the brass union.

5. Remove the vinyl cap and unscrew the gas control convertible regulator and reverse to Natural gas side and screw back into place.

The red LP ring will be up just under the vinyl cap. Reattach vinyl cap. Refer to figure illustrating the gas valve.

6. Place LP gas main burner orifice(s) in conversion kit. Attach conversion kit to manifold pipe. Attach new label to unit nameplate

indicating that the unit was converted to Natural gas.

7. Turn on gas supply to furnace and check all gas connections for leaks with soap solution, watching for bubbles on all gas connec-

tions.

8. Turn on electrical power to unit and turn on furnace to verify proper operation. It may take several tries for ignition to completely

purge all the air from the gas line.
