PUMP PRESSURE ADJUSTMENT
FOR HEATERS WITH FUEL FILTER/
CANISTER EXTERNAL TO PUMP
1. Remove pressure gauge plug from fuel
pump port marked “GAUGE.”
2. Install accessory pressure gauge (part
number 110380-01) to fuel pump port
marked “GAUGE” (see Figure 11).
3. Start heater (see Operation, page 5). Al-
low motor to reach full speed.
4. Adjust pressure. Use small flat blade
screwdriver to turn slotted screw at fuel
pump pressure adjusting port. Turn screw
clockwise to increase pressure. Turn
screw counterclockwise to decrease pres-
sure. See specications in Figure 11 for
correct pressure for each model.
5. Stop heater (see page 5).
6. Remove pressure gauge. Replace pres-

PUMP PRESSURE ADJUSTMENT
FOR HEATERS WITH FUEL FILTER
INTERNAL TO PUMP
1. Remove pressure gauge plug from fuel
pump port marked “GAUGE.”
2. Install accessory pressure gauge (part
number 110380-01) to fuel pump port
marked “GAUGE” (see Figure 12). Do
not use bleeder valve port to check the
pressure. The bleeder valve port contains
pressure higher than operating pressure.
Setting pump pressure with gauge in the
bleeder valve port results in wrong operat-
ing pressure.
3. Start heater (see Operation, page 5). Al-
low motor to reach full speed.
4. Adjust pressure. Use small flat blade
screwdriver to turn slotted screw at fuel
pump port at top right side of pump. Turn
screw clockwise to increase pressure.
Turn screw counterclockwise to decrease
pressure. See specications in Figure 12
for correct pressure for each model.
5. Stop heater (see page 5).
6. Remove pressure gauge. Replace pres-
sure gauge plug in fuel pump port marked
“GAUGE.”
