The furnace should be operated for a minimum of 10 minutes to
reach steady state conditions before fine tuning combustion. The
warm up time is ideal for testing the oil pump pressure.
Drill a 1/4-inch test port in the venting between the furnace flue
outlet and draft regulator (barometric damper). Insert a stack ther-
mometer and note the flue gas temperature. The flue gases should
be within a range of 350°F to 450°F. If the flue gases are below the
range, it may be necessary to slow down the blower fan. If the flue
gases are above the range, the blower fan may require speeding up
or the barometric damper needs adjusting. Stack temperature varies
directly with the system temperature rise. System temperature rise is
the difference between the furnace outlet temperature and furnace
inlet temperature as measured in the vicinity of the connection
between the plenum take-offs and the trunk ducts. Temperature rise
value is listed on the system rating plate.
Perform a smoke spot test. The smoke spot should not exceed No. 1
on the Bacharach Scale.
After the air adjustments have been completed, re-check the draft
pressure at the test port on the burner mounting plate as shown in
Figure 2.
The draft should be adjusted to -0.02 inches w.c.
In the United States, the Beckett AF Burner may be equipped with
Beckett's "Inlet Air Shut-Off" to increase efficiency. (Beckett Part No.
AF/A 5861).
NOTICE
USE OF THE INLET AIR SHUT-OFF COULD CAUSE
POST COMBUSTION NOZZLE DRIP.

Riello burners are factory set with respect to nozzle size, pump pres-
sure, air gate and turbulator adjustments for each model and firing
rate; therefore, do not use the above listed set up procedures.
Riello specifications are listed in
Table 3C,

.
Consult the Riello Installation Instructions supplied with the Burner
for specific information concerning burner adjustments, operation,
and trouble-shooting.
