23.6. COMBUSTION ADJUSTMENT AND VERIFICATION
To enjoy the efficiency of our oil burning units, you must
respect the following criterion:
Oil burning units must be connected to flue pipes having
at all times a sufficient draft to ensure an efficient and
safe operation of unit.
Before turning on the oil unit, make sure that the sealed
vision cap (SE53352) is installed and secured on the
vision tube with the screw provided. The chamber is
calibrated so that there is a slight positive pressure, which
optimizes the efficiency of combustion. The presence of
the sealed vision cap thus prevents the return of oil odor.

23.6.1. 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 DRAFT = 0.01 TO 0.02 IN.W.C. (THE DRAFT OVER THE FIRE MUST BE MEASURED BY
THE SCEALED CAP OF THE VISION TUBE'S PULSATION TRAP).
E- SMOKE TEST BETWEEN 0 AND 1 ON THE SHELL BACHARACH SCALE (TRACES).
F- DRAFT IN THE CHIMNEY = 0.02 IN.W.C.
G- PERCENTAGE OF EXCESS AIR = 20 TO 40%, 12% CO2, 5% O
H- AVERAGE EFFICIENCY OF 83% TO 87% BASED ON THE TYPE OF BURNER AND ITS INPUT (SEE
SECTION 24.1 -
I-
BURNER'S AIR ADJUSTEMENT: 0-7. 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 IN.W.C. in the evacuation pipe of the wood
burning side, at all times. 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.
