On a call for heat, the thermostat
will actuate,
com-
pleting
the circuit
to the boiler.
In turn, the ignition
systems
are activated
and ignition wilt begin.
In the event of a low water condition,
an automatic
low water cut-off device
will interrupted
power be-
tween
the low water
cut-off
and the burner.
The
burner will remain off until the low water condition
is
corrected,
(i.e.,
manually
restore
boiler
water
or
utilize a water feeder device which wilt automatically
restore water to its normal operating
level).
IMPORTANT
TO THE INSTALLER
- Before putting
the boiler in operation,
test the mechanical
tow water
cut-off device for proper operation.
While burner is
on, open
the blow-off
valve
located
in the lower
portion of the cut-off body. This will drain the water
quickly from the cut-off body and break the circuit to
the burner.
If it does not, replace
control.
The venting system should
be inspected
at the start
of each heating
season.
Check the vent pipe from
the boiler to the chimney for signs of deterioration
by
rust or sagging
joints.
Repair
if necessary.
Remove
the vent pipe at the base of the chimney
or
flue and, using a mirror,
check for obstruction
and
verify compliance
to the latest revision of the NFPA
211.
The lever of the pressure
relief valve (Figure
12) on
the boiler should
be operated
periodically
to make
sure that it is functioning
properly.
i
t
.......................
( .....
The pressure
relief valve should
open before
the
steam pressure
exceeds
the 15 lb. reading
on the
gauge. If this pressure
is exceeded
and the pressure
relief valve leaks steam when the boiler is operating
at normal
pressures,
it should
be immediately
replaced.
Corrosion
can build up rapidly at the valve
seat and prevent
its functioning
as a safety device.
(See oil burner
instructions
for nozzle
and electrode
setting).
DO NOT SET FIRE VISUALLY.
Instruments
are the only
reliable
method
to
determine
proper
air
adjustments.
An
improperly
adjusted
burner
causes
soot and
high
fuel
bills
because
of
incomplete
combustion
of the fuel
oil. This
in turn
may
req u ire excessive
boiler maintenance,
service
costs,
and in some instances,
house
cleaning
or
redecorating.
A
competent
service
mechanic
should
be consulted
to make
the
proper
adjustments
with a smoke
tester,
CO 2
indicator,
and draft gauge.
NOTE:
Bacharach
\0 r Dwyer
test kits include these
instruments;,
A. Check oil burner nozzle to make certain it is tight
in adapter.
Burner
mounting
bolts should be tight.
B. Check electrode
setting, as they may have been
jarred out of position
during transportation.
C. Lubricate
burner
motor if necessary.
