❏ #HECKTEST
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 proper-
ly connected to valve outlet and arranged 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 plumb-
ing contractor or authorized 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 compo-
nents over time, rendering the valve inoperative.
Such conditions are not detectable unless the valve
and its components are physically removed and
inspected. This inspection must only be conducted
by a plumbing contractor or authorized inspection
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 pressure 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.
❏ 2EVIEWWITHOWNER
1. Review the User’s Information Manual with the owner.
2. Emphasize the need to perform the maintenance schedule
specified 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.
❏ #LEANINGBOILERHEATINGSURFACES
The boiler contains ceramic fiber and fiberglass
materials. Use care when handling these materials
per instructions on page 33 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 col-
lector 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 surround-
ing area.

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 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.
