pressure
to build up. Run a temporary
connection
from one of the drain
valves
to a nearby
sewer.
Connect
to a drain valve on the opposite
end of the
boiler from feed water inlet, if possible.
Shut off the
oil burner, open drain valve and blow down the entire
contents
of boiler.
Allow boiler to thoroughly
cool and slowly refill to water
line. Repeat as many times as required until blow off
water is clear. Owner should blow down boiler at least
once each month d the heating season.
If an exceptional
amount
of dirt or sludge
seems to
be present in the boiler, a boiler cleaning
compound
made
by a reputable
manufacturer
may be used
according
to the instructions
of the manufacturer
of
the compound.
When
any type of cleaning
com-
pound
is used, care must be taken to thoroughly
flush all traces of the compound
out of the boiler.
Following
blow down allow the boiler to coot. Add
fresh water slowly. Be certain to blow enough
times
as required
to remove
compounds
from system.
The area around the boiler must be kept clear and
free of combustible
materials,
gasoline
and other
flammable
vapors
and liquids.
The free flow of combustion
and ventilation
air to the
boiler
and boiler
room
must not be restricted
or
blocked.
Periodic
inspection
and tightening
of the tanktess
heater/cover
plate bolts will reduce the risk of leaks.
See parts 3 and 5 under
"Coil and Cover
Plate
Replacement
Parts."
Operation
should
be checked,
with burner
on, by
opening
the blow-off
valve
located
in the
lower
portion of the low water 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 the control.
During the heating season, the blow-off valve on the
low water cut-off should
be opened once a week to
flush out the sediment
chamber so the device will be
free to function
properly.
(Figure
12) Use a pail to
catch the discharge.
It is suggested
that a qualified
service
agency
be
employed
to make an annual inspection
of the boiler
and heating
system.
They are experienced
in mak-
ing the inspections
outlined
above and, in the event
repairs or corrections
are necessary,
can make the
proper changes
for safe operation
of the boiler.
