Combustion Adjustment And Verification - PSG -3000 Installation And Operating Instructions Manual

COMBUSTION ADJUSTMENT AND VERIFICATION

To enjoy the efficiency of our oil burning units, you must respect the following criteria:
TOOLS REQUIRED:
- DRAFT GAUGE
- SMOKE TESTER
- PUMP PRESSURE GAUGE
- NOZZLE AND ELECTRODES POSITION GAGE
- COMBUSTION TESTER
CHECK LIST:
- SELECTION OF NOZZLE AND HEAD
- NOZZLE / ELECTRODES POSITION IN RELATION TO THE HEAD
- PUMP PRESSURE
- OIL LINE IS BLEED
- LOW FIRING RATE BAFFLE (INSIDE THE BURNER) REQUIRED FOR UH-2000-3000-4000 AND
UH-CADDY. NOT REQUIRED FOR UH-4500
- FAN SPEED
- BAROMETRIC DAMPER POSITION
COMBUSTION VERIFICATION PROCEDURE:
A- DRILL A 9/32" DIAMETER HOLE IN THE EVACUATION PIPE APPROXIMATELY 18" FROM THE
OUTLET.
B- CLOSE THE DOOR AND THE AIR INTAKE(S) OF THE WOOD BURNING FURNACE.
C- LIGHT THE BURNER FOR AT LEAST 10 TO 15 MINUTES.
D- OVER THE FIRE DRAUCHT = -0.01 TO -0.02 W.C. (THE DRAFT OVER THE FIRE MUST BE
MEASURED IN THE OPENING IN THE PULSATION TRAP).
E- SMOKE TEST BETWEEN 0 AND 1 ON THE SHELL BACHARACH SCALE (TRACES).
F- DRAFT IN THE CHIMNEY =-0.02 TO -0.04 W.C.
G- PERCENTAGE OF EXCESS AIR = 20 TO 40%, 12% CO2, 4.6% O
H- AVERAGE EFFICIENCY OF 80 TO 85 %.
I- TIGHTEN ALL THE LOCKING SCREWS AFTER COMPLETING THE FINAL ADJUSTMENT.
N.B. – The barometric damper provided with the appliance must be properly installed on the flue pipe of the
oil burning unit. The purpose of the damper is to adjust the draft in the evacuation pipe of the oil
burning unit to the recommended level. Since the evacuation pipe of the oil burning unit is connected
on the evacuation pipe of the wood burning furnace, the minimum draft to be respected is 0.04"
W.C. in the evacuation pipe of the wood burning side, at all time. In fact, a barometric damper
that would be opened too wide could cause an important loss of draft in the evacuation pipe
of the wood burning furnace.
