FIGurE 12.0: FluE DraFt taPPInG
17) Check the vacuum at the inlet of the fuel pump. Make sure that the vacuum does not exceed the fuel pump manufacturer’s
limit (consult the pump manufacturer’s instructions).
18) Close the flame observation cover.
19) After chimney has warmed-up for at least 5 minutes, adjust barometric draft regulator to obtain a draft at the 1/4” tapping
shown in Figure 12.0 that is within the range shown in Table 12.1. DRAFT AT THIS LOCATION MUST NEVER BE
POSITIVE.
20) Check the CO2 and confirm that it is between the minimum and maximum limits shown in Table 12.1. Adjust if
necessary.
21) Verify that the smoke level still does not exceed #1 and that the draft in the breech is still within the range prescribed by
Table 12.1.
22) Turn off the burner and remove pressure gauge. Install and tighten gauge port plug, then restart the burner.
23) Check for clean cutoff of the burner. Air in the oil line between fuel pump and nozzle will compress, while burner is
running, and expand, when burner shuts off, causing oil line pressure to drop and nozzle drip after burner stops. Cycle burner
on and off 5 to 10 times to purge air completely.
24) Check thermostat operation by raising or lowering its set point as required, cycling burner on and off.
25) Verify primary control operation and safety features according to procedure outlined in the instructions furnished with
the burner.
26) Check pressure limit control operation. Jump thermostat terminals and allow burner to run until boiler pressure exceeds
cut-in pressure plus the differential. The burner should shut down.
27) Check low water cut-off operation. With the thermostat still jumped, fire the boiler and crack the boiler drain valve so that
water is slowly drained from the boiler. Confirm that the burner shuts down before the water level drops below the bottom
of the sight glass.
Do not permit the boiler to fire without water visible in the sight glass
. Add water to the boiler and
confirm that the burner restarts. Remove thermostat jumper and reconnect thermostat upon check completion.
28) After the boiler has operated for approximately 30 minutes, check the boiler and heating system for leaks. Repair any
leaks found at once.
29) After the above checks have been completed, leave thermostat(s) at desired setting. Leave all instructions provided with
