Installing 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
1.
Refer to Figures 4G, 4H, and 4I. Note that the metering pump is shipped with the pump head
already positioned for vertical wall mounting.
2.
Use the appropriate type of bolts and washers (user-supplied) to securely mount the metering
pump to the appropriate wall in your building at a distance from the tank that complies with the
suction oil line requirements.
