For Your Safety, Before Operating

The Boiler, Read This Manual

WELCOME TO OUR VALUED CUSTOMER

You are now the owner of a Slant/Fin Prodigy 21
gas-fired boiler, another quality heating product
designed and manufactured by an industry leader ,
to provide your family with many years of reliable
comfort and trouble-free performance.

The care and maintenance of your new boiler is
important to prevent a hazardous condition which
might result from lack of proper servicing.
Therefore, you should perform regular “owner”
inspections as described in this manual (and
report any concerns to a qualified service
technician) as well as have y our boiler serviced by
a qualified service technician at least once a year,
preferably before the beginning of each heating
season.

At least once each month during the heating
season, perform the following inspections:

Check Vent Tubing: Look for leakage at joints and
sagging of vent tubing runs. If evident, call a qualified
service technician.

Check Vent Terminal (Outside): Look for and remove any
obstructions (i.e. leaves, shrubs, snow).

Check Water Piping: Look for leaks around boiler and at
all joints. If evident, call a qualified service technician.

Check System Water Pressure: The temperature/pres­sure gage indicates the pressure in the boiler for each
water temperature. For most installations, it should
indicate about 12 psi to 15 psi for 70° to 100° water
temperatures and from 15 psi to 25 psi for temperatures
up to 240°. Ask your installer or service technician to
explain and show you what normal pressures to look for.

If pressure decreases from normal, the system is losing
water; if pressure increases from normal, the boiler relief
valve will open to relieve pressure (water will be evident
on floor below relief valve discharge piping). In either
case, call a qualified service technician.

At least once a year, check the air filter: Replace it
(recommended) or clean it. For access to the filter,
remove boiler front cover by pushing down on top center
portion of cover until support clip releases cover at top,
then lift off of support clips at bottom of cover.

Open air filter box cover by rotating the 1/4 turn fastener
on top of cover, then swing open at hinge.

Slant/Fin replacement air filter, part number 65-0524,
must be used. The filter can be cleaned with soap and
water. Shake off excess moisture before replacing.

In the case of severe outside dust/dirt conditions which
cause above-average accumulation on the filter, it may
be necessary to change it (or clean it) more often. This
procedure may be done by user or service technician,
providing a record is kept of each replacement or
cleaning date to assure an established diligent routine.

OF Y OUR BOILER

ANNUAL TECHNICIAN INSPECTIONS

Before each heating season, call your qualified
service technician to perform the following
inspections (and repair any problems encountered).

Check Vent System: For corrosion, obstructions, leaks
or sagging. Will require disassembling and resealing of
vent tubing.

Check Water System: For water piping leaks, properly
filled boiler and proper system air elimination.

Check Gas Piping:

For gas valve and piping leaks.

Check Boiler Controls:

For correct settings and

functioning. To include safety controls and calibration.
Check Air Filter: Replace (recommended) or clean.
System Heat Exchanger and Burner: For sooting,

corrosion or improper operation.
Blower and Circulator: Sealed components which do

not require lubrication.

The PRODIGY 21 control light panel has a complete set
of LED indicator lights which provide important
information at a glance about boiler operation:

Power Indicator (RED): Steady ON means there is
electrical power to the boiler. Light will come on when
power is provided to boiler.

Diagnostic Indicator (RED):

Steady ON or intermittent

flashing indicates a system operation problem.
Full Input Indicator (AMBER): Steady ON means the

boiler is running in high-fire mode. Light will come on
when boiler starts up; will go off when the boiler enters
the low-fire mode or shuts off.

Reduced Input Indicator (GREEN): Steady ON means
boiler is running in low-fire mode. Light will come on
when the boiler automatically switches to the fuel­saving low-fire mode; will go off when boiler returns to
high-fire mode or shuts off.

WHA T THE INDICA T OR

LIGHTS TELL Y OU

Before calling a qualified service technician, check
the following first:

• Room thermostat is calling for heat?

• Fuse or circuit breaker is OK?

• Boiler service switch is ON?

• Gas supply is available to gas meter?

• Manual main gas shutoff is open?

• Boiler gas control arm is in ON position?
Then, observe indicator lights: You can help provide

useful information to the service technician so the
technician can arrive with appropriate replacement parts.

Carefully note the red diagnostic indicator light. When a
system failure occurs, and there’s power to the boiler,
the indicator light will show a series of quick flashes.
There will be a short interval between the series when
the indicator stops flashing.

Count the number of flashes that occur after the short
no-flashing interval. Using the chart above, determine
correct failure code for number of flashes you counted.

Call a qualified service technician and report your boiler
model plus the number of flashes you counted and the
code for the flashes.

Note: The boiler will attempt restart each hour and after
a power interruption. If boiler restarts, diagnostic light
will turn OFF. If boiler does not restart, diagnostic light
will return to either steady-on or the series of flashes.

IN CASE YOUR

BOILER SHUTS DOWN
