PRESSURE CHECK
use Easy Flow Bleed Valve Port for the for the 7000
series.
The Easy Flow Bleed Valve Port contains pressure higher
than operating pressure. Setting pump pressure with gage
in the Easy Flow Bleed Valve Port results in WRONG
operating pressure. The 2000 series and 7400 series are
exceptions (See Figure 17).
CUTOFF PRESSURE
Average cutoff pressure for model "A" and "B" fuel pumps is
80 psig. To check cutoff pressure, install pressure gage in
nozzle port. Run burner for short period of time. Shut
burner off. Gage shows cutoff pressure.
10 psi on inlet line or return line at the pump. A
pressure greater than 10 psi may cause damage to the
shaft seal.
SOLENOID WIRING
electrical shock or equipment damage.
Lead wires on these devices are long enough to reach the
junction box on most burner installations.
For all other applications, wire solenoid in parallel with
burner motor (see Figure 15). All electrical work should be
done according to local and national codes.
