[] 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.
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.
Boiler relief valve
1. inspect the boiler relief valve and the
relief valve discharge pipe for signs of
weeping or leakage.
2. If the relief valve often weeps, the
expansion tank may not be working
properly.
immediately contact your qualified
service technician to inspect the
boiler and system.
Automatic air vents (if used)
1. Remove the cap from any automatic B----_..
air vent in the system and check
operation by depressing valve B
slightly with the tip of a screwdriver.
2. If the air vent valve appears to be
working freely and not leaking, replace
cap A, twisting all the way on. Loosen
cap A one turn to allow vent to operate.
3. Have vent replaced if it does not
operate correctly. '....
[] Periodically
Test low water cut-off (if installed)
1. If the boiler or system is fitted with a low water cut-off device,
test the device following the cut-off manufacturer's instructions.
[] Periodically
Oil motors equipped with oil cups
1. Burner or circulator 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.
[] Every 6 months
Operate boiler relief valve every 6months
To avoid water damage or scalding due to valve
operation, a metal discharge line must be connected
to relief valve outlet and run to a safe place of dis-
posal. This discharge line must be installed by a
qualified heating installer or service technician in
accordance with the instructions in the Boiler
Manual. The discharge line must be terminated so
as to eliminate possibility of severe burns should
the valve discharge.
1. Before proceeding, verify that the relief valve outlet has been
piped to a safe place of discharge, avoiding any possibility of
scalding from hot water.
2. Read the boiler pressure/temperature gauge to make sure
the system is pressurized.
3. Lift the relief valve top lever slightly, allowing water to relieve
through the valve and discharge piping.
4. If water flows freely, release the lever and allow the valve to
seat. Watch the end of the relief valve discharge pipe to ensure
that the valve does not weep after the line has had time to
drain. If the valve weeps, lift the seat again to attempt to clean
the valve seat. If the valve continues to weep afterwards,
contact your qualified service technician to inspect the valve
and system.
5. If water does not flow from the valve when you lift the lever
completely, the valve or discharge line may be blocked.
Immediately turn off switch to the boiler and close fuel valves.
Call your qualified service technician to inspect the boiler and
system.
[] End of season shutdown
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.
