Installing the pressure oil line to the boiler:
(1) Refer to Figure 17 to view the pump oil outlet options.
(2) Determine the desired position of the oil outlet and rotate the 1/4” T accordingly.
(3) Determine the length of copper tubing needed for the pressure line (from pump to boiler)
and use the appropriate sized tubing. If the pressure line is less than 100 feet, 3/8” copper
tubing can be used. If the pressure line is greater than 100 feet, use 1/2” copper
tubing.
NOTICE:
There are installations that will operate well with a long pressure oil line. However,
to ensure proper performance with variables such as oil temperature and viscosity, Clean
Energy Heating Systems does not recommend exceeding 150 feet of total pressure oil line.
(4) Refer to Figure 18.
(5) Connect the pressure oil line to the aluminum connector block on the side of the boiler.
NOTICE:
By connecting the oil line to the connector block, the swivel fitting is utilized which
allows the front clean out door to be opened without disconnecting the oil line.
