Using Cleaning Compound
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 compound 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 cool. 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 tankless heater/
cover plate bolts will reduce the risk of leaks. See parts 3 and
5 under "Coil and Cover Plate Replacement Parts."
MAINTENANCE PROCEDURES
Electronic Low Water Cut-Off
Operation of the probe and control should be checked, with
the burner on, by draining the water via the drain on the
bottom of the boiler. This will drain the water quickly from
the boiler and break the circuit to the burner. If it does not
inspect the probe for scaling. If scaling is present, clean off
the probe, refill the boiler until the ELWCO is satisfied, and
perform the check again.
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 making the inspections
outlined above and, in the event repairs or corrections are
necessary, can make the proper changes for safe operation
of the boiler.
