Check monthly
Boiler and system piping
1. Visually inspect for leaks around piping, circulators, relief valve
and other fittings. Check oil lines and boiler air for signs of oil
leakage. Immediately call a qualified service technician to
repair any leaks.
Have leaks fixed at once by a qualified service tech-
nician. Continual fresh makeup water will reduce
boiler life. Minerals can build up in sections, reduc-
ing heat transfer, overheating cast iron, and caus-
ing section failure.
Do not use petroleum-based cleaning or sealing
compounds in boiler system. Severe damage to
boiler and system components can occur, resulting
in possible severe personal injury, death or sub-
stantial property damage.
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 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
plumbing 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
components 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 pressure 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.
Venting system
1. Visually inspect all parts or the flue gas venting system for
any signs of blockage, leakage or joints or deterioration of
the piping. Notify your qualified service technician at once if
you find any problem.
Failure to inspect the vent system as noted above
and have it repaired by a qualified service techni-
cian can result in vent system failure, causing se-
vere personal injury or death.
•
Do not drain boiler unless exposure to freezing temperatures
will occur.
•
Always keep manual fuel supply shut off if burner is shut down
for an extended period.
a. Turn off switch to boiler.
b. Close fuel valves.
c. Turn off water feed valve.
d. Cover burner to protect from dust and dampness.

Periodically
Oil motors equipped with oil cups
1. Burner motors may require oiling. Such motors are fitted with
oiling cups. Use a few drops only of S.A.E. 20 detergent oil.
Do not use household oils. Excessive oiling can damage
motors. Do not attempt to “fill up” the oiling cup.
Test low water cutoff(s)
Probe-type low water cutoff
1.
Turn off power to boiler and wait 5 minutes.
2. Drain water to bottom of gauge glass.
3. Turn on power.
4. Set thermostat to call for heat. Red
neon lamp on low water cutoff should
light.
5. Wait 5 minutes. Boiler should not fire.
6. Refill boiler to correct water line. Red
lamp should go off.
7. Wait 5 minutes. Boiler should fire.
8. Return thermostat to normal setting.
Float-type low water cutoff (by others, if used)
1.
Blowdown control and test per control manufacturer’s instructions.
Scald potential. Do not blowdown low water cutoff
unless blowdown piping has been installed
according to control manufacturer’s instructions. If
piping is not installed, call a qualified service
technician.
