Boiler relief valve
1. After following the warning directions below, if the
relief valve weeps or will not seat properly, replace the
relief valve.
Before testing, make certain discharge pipe
is properly connected to valve outlet and ar-
ranged to contain and safely dispose of boiler
discharge. Wear gloves to protect your hands
from hot surfaces.Verify that discharge piping
is installed in accordance with this manual
and the instructions on the relief valve tag.
Failure to comply will expose operator and
others to severe personal injury or death.
Safety relief valves should be reinspected AT
LEAST ONCE EVERY THREE YEARS, by
a licensed plumbing contractor or autho-
rized inspection agency, to ensure that the
product has not been affected by corrosive
water conditions and to ensure that the valve
and discharge line have not been altered or
tampered with illegally. Certain naturally
occurring conditions may corrode the valve
or its components over time, rendering the
valve inoperative. Such conditions are not
detectable unless the valve and its compo-
nents are physically removed and inspected.
This inspection must only be conducted by
a plumbing contractor or authorized inspec-
tion agency — not by the owner. Failure to
reinspect the boiler relief valve as directed
could result in unsafe pressure buildup, which
can result in severe personal injury, death or
substantial property damage.
Check the setting of the boiler limit control.
The control should never be set with a pres-
sure above 10 psig. Operating at a higher
pressure can cause damage to the boiler relief
valve.
The boiler relief valve must be tested at least
monthly during the heating season to verify
the valve and discharge piping flow freely. If
corrosion and/or deposits are noticed within
the valve body, testing must be performed
more often. A "try lever test" must also be
performed at the end of any non-service
period. Follow the instructions below for a
"try lever test":
With the system at operating pressure, lift
and hold the test lever fully open for at least 5
seconds to flush the valve seat free of sediment
and debris. Then release lever and permit the
valve to snap shut.

❏ Review with owner
1. Review the User's Information Manual with the owner.
2. Emphasize the need to perform the maintenance schedule speci-
fied in the User's Information Manual (and in this manual as well).
3. Remind the owner of the need to call in a licensed contractor
should the boiler or system exhibit any unusual behavior.
4. Remind the owner to follow the proper shutdown procedure and
to schedule an annual start-up at the beginning of the next heating
season.
❏ Cleaning boiler heating surfaces
The boiler contains ceramic fiber and fiberglass materi-
als. Use care when handling these materials per instruc-
tions on page 28 of this manual. Failure to comply could
result in severe personal injury.
1. Follow shut-down procedure
2. Disconnect breeching and remove damper (if used) and draft
hood.
3. Remove upper rear jacket panel. Turn back jacket insulation to
expose collector hood.
4. Remove collector hood. Clean excess boiler cement from collector
hood and cast iron sections.
5. Remove burners from base of boiler. Follow "Cleaning main
burners" to thoroughly clean burners. Place newspaper in base
of boiler to collect soot that will fall.
6. With a wire flue brush, clean between the sections.
7. Remove paper and soot. Vacuum or brush base and surrounding
area.
8. Replace collector hood. Seal with boiler cement.
9. Replace draft hood, damper (if used) and breeching.
10. Replace insulation and jacket panel.
11. Replace main burners.
Cleaning main burners
1. Vacuum or brush burners to remove dust and lint.
When replacing, burner tubes must be seated in slots in
the back with openings face up. Gas orifices must inject
down center of burner. Failure to properly seat burners
will result in severe personal injury, death or substantial
property damage.
Annual shut-down procedure
1. Follow correct lighting/operating instructions on boiler.
2. Do not drain system unless exposure to freezing temperatures will
occur. If antifreeze is used with system, do not drain.
3. If complete boiler and piping system must be drained to avoid
freezing, provide method to drain water from both ends of boiler
at or below return tapping level.
