AnnuALLy:
To assure trouble free operation, it is
recommended that the flue passages, combustion
chamber area (target wall, fire door insulation) burner
adjustment, operation of the controls, and boiler seals
(fire door gasket or silicone seal, cast iron sectional
seals, flue collector) be checked once each year by
a competent Service Technician.
Before the start of
each heating season
(or whenever the system has
been shut down for extended periods of time) recheck
the whole system for water, oil, and vent piping leaks.
Replace or patch any leaks or seals that are faulty.
VenT PiPe:
Visually inspect the entire venting system
once a month for any signs of leakage, deterioration,
or soot build up. If the vent pipe shows any signs of
leaking or deterioration, replace it immediately. If it
shows any signs of soot build up, clean the vent pipe
and have the burner settings and combustion checked
by a competent professional.
ReLieF VALVe:
This valve should open automatically
when the system pressure exceeds the pressure
rating (usually 30 psi) of the relief valve. Should the
valve ever fail to open under this condition, shut down
the system. Drain the system until system pressure
is reduced below the relief valve pressure rating.
Then contact a competent Service Technician to
replace the valve and inspect the heating system and
determine the cause, as this problem may indicate
an equipment malfunction. The relief valve should
be tested bimonthly during the heating season. Prior
to testing, make certain a discharge pipe is properly
connected to the valve outlet and arranged so as to
contain and safely dispose of boiler discharge. Hold
the trip lever fully open for at least five seconds in order
to flush free any sediment that may lodge on the valve
seat. Then permit the valve to snap shut. Refer to the
valve manufacturer’s instructions packaged with the
valve for more details.

WATeR sysTeM:
If the system is to remain out of
service during freezing weather, always drain it com-
pletely (water left in the system will freeze and crack
the pipes and/or boiler).
MAINTENANCE
oiL BuRneR MAinTenAnCe:
For the Beckett AFG,
the following preventative maintenance items should
be performed annually, preferably prior to the heating
season.
1.
Fuel Filter
This should be replaced so as to pre-
vent contaminated fuel from reaching the nozzle.
A partially blocked fuel filter can cause premature
failure of the fuel pump.
2.
Fuel Pump unit
Replace pump screen and clean
pump unit to maintain fuel delivery to the nozzle.
3.
ignition electrodes
Clean and adjust as per
manufacturer’s recommendations, so as to maintain
reliable ignition of oil.
4.
nozzle
Replace so as to maintain safe and reli-
able combustion efficiency. Always replace with the
exact nozzle as required in the charts in the back
of this manual.
5.
Fan and Blower Housing
These must be kept
clean, free of dirt, lint and oil so as to maintain the
proper amount of air the fuel requires to burn.
6.
Check the burner settings and adjust as need
-
ed.
noTe:
If any component parts must be replaced,
always use parts recommended by the burner
manufacturer.

OFF
Assure that the boiler is at zero pressure be
-
fore removing the relief valve or any probe.
open the safety valve to relieve all internal
pressure prior to proceeding. safety valve
discharge piping must be piped such that
the potential for burns is eliminated.
DANGER
!
Probe type low water cut-off devices require
annual inspection and maintenance.
WARNING
!
Although these devices are solid state in their op-
eration, the probe is exposed to possible con-
tamination in the boiler water and subject to fouling.
