Figure 4G - Vertical Mounting of the Metering Pump
Preparing for Installation
Before starting installation of the metering pump, review Figures 4G, 4H, and 4I to become familiar
with the metering pump components. You will also need to accomplish the following activities:
• Verify that you have the proper metering pump for your furnace (note the specific gear motor
part numbers shown in Figure 4H).
• Gather all required tools and materials as needed for installation; as indicated in the
following procedures, some materials (e.g. fittings, tubing) are to be user-supplied.
•
Standard mounting
is vertical mounting on a wall;
this pump installation is recommended.
Alternate mounting
is horizontal mounting on a bracket. Be sure to carefully follow the
appropriate procedures/diagrams for pump mounting.
• For optimal metering pump functioning, mount the pump at a distance from the oil tank that
will comply with the following requirements:
The suction oil line may NOT exceed
6 feet TOTAL vertical lift AND 4 feet TOTAL
horizontal
lift.
Standard Mounting: Vertical Positioning
