Installing the Connector Block, Oil Line Tubing, and Air Line Tubing
ATTENTION: DO NOT use teflon tape on any fittings. Teflon tape residues will plug vital burner
components.
Installing the Connector Block on the Furnace Door
1. Refer to Figure 3G.
2. Use the two (2) bolts to install the aluminum
connector block onto the furnace cabinet.
3. Remove and discard the red caps and plugs from the
fittings and ports on the connector block. DO NOT
allow any dirt/debris to enter these components
during furnace assembly.
Figure 3G - Installation of Connector
Block and Oil Line
ATTENTION: The connector block includes an
accumulator. The accumulator functions like a shock
absorber on the oil line to prevent pressure buildup and
protect vital burner components. It is important that the
connector block is installed as shown so that the accumulator
is in a vertical position to prevent sediment from settling in
the accumulator. Never operate your furnace without the
connector block and accumulator properly installed on the
furnace, or damage may occur to vital burner components.
Installing the Oil Line Tubing
ATTENTION: DO NOT disassemble the compression
fitting from the swivel fitting. To prevent leaks, the NPT
threads of the compression fitting have been sealed with
hydraulic sealant during assembly of the fittings at the
factory.
1. Remove and discard the red caps from the oil line
tubing.
2. Loosely install the oil line tubing into the oil line
fitting on the burner.
3. Use a wrench to slightly rotate the oil line fitting on the burner counterclockwise so the tubing
lines up with the swivel assembly. Slightly bend the tubing as shown in Figure 3H, if required,
to "line up" the oil line.
4. If necessary, use a tubing cutter to cut the tubing to the proper length.
ATTENTION: Due to adjustment of the burner hinge bracket, the oil line tubing may need to
be cut to fit properly. DO NOT lift up on the burner when installing the oil line tubing to
compensate for oil line tubing that is too long. This will place the weight of the burner on the
swivel fitting and result in leaks at the swivel fitting seal.
