Tjernlund 950-2043 ND-1 Post Purge Burner Kit 8504004 Rev 0196 - Manual (Page 2)

Make sure all power is disconnected from the furnace/boiler before
attempting to install the ND-1. Failure to do so can cause electrical
shock resulting in personal injury or death.
INSTALLATION OF OIL SOLENOID VALVE ON NON-BECKETT
BURNERS
1. Apply pipe sealant to the Solenoid Elbows, insert and tighten to posi-
tion necessary for oil tubing.
2. Place the metal “U” Solenoid Bracket around Solenoid Valve.
3. Insert 1/2” Chase Nipple to Solenoid Valve and tighten.
4. Using screws provided, attach Solenoid to appliance wall. NOTE:
Solenoid tubing is 8” long. If Oil Tubing does not reach pump and
burner chamber the installer must provide a means of mounting the
Solenoid Bracket on an extension. If mounting on a boiler attach
Solenoid to exterior boiler wall with the 3/8” self tapping screws using
the larger holes in Bracket, (See Diagram C). If mounting on a fur-
nace install Solenoid on interior wall with the 3/8” self tapping screws
using the smaller holes in Bracket, (See Diagram D).
5. Connect one 8” Tube Assy. from the pump to the Valve and the
remaining 8” Tube Assy. from the Valve to the nozzle line paying
attention to the direction of flow as shown, (See Diagram E).
6. The 24” long 3/8” diameter metal Conduit will have to be added to
accommodate the placement of the Solenoid Valve on the wall of
the appliance.
7. Thread wires through metal conduit for connection to primary control.
INSTALLATION OF RELAY AND JUNCTION BOX EXTENSION ON
NON-BECKETT BURNERS (DIAGRAM E)
1. NOTE: Install the junction box extension only after the wiring has
been completed.
2. Rotate the junction box extension so that the relay locates to the
front. (toward the cabinet door)
3. Align the junction box extension to the top of the existing burner
motor junction box.
4. Insert and start the 2 1/2” sheet metal screws to locate the junction
box extension to the existing junction box.
5. Install the primary control and tighten the 2 1/2” sheet metal screws.
