Installing the pressure oil line to the furnace:
(1) Refer to Figure 21.
(2) Determine the length of copper tubing needed for the pressure line (from pump to furnace)
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. An adapter fitting may be needed when using 1/2” copper to make the connection
between the tubing fitting and mini ball valve (50039 - 1/8 MNPT x 1/4 FNPT).
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.
(3) It is ideal to have the pressure oil line sloping up from the pump to the furnace. This
reduces the risk of air pockets and nuisance shut downs.
(4) Refer to Figure 22.
(5) Connect the pressure oil line to the aluminum connector block on the side of the furnace.
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.
