Annual Inspection - Before Start of Heating Season
Periodically or at start of heating season inspect boiler, vent
and vent pipe for accumulation of soot or scale deposits.
When soot is present on section walls and
fl
ueways,
improper combustion results, causing additional sooting
and scaling until
fl
ueways are completely closed.
A. To remove soot and scale from
fl
ueways, remove
top jacket panel, top clean-out plate and burner. See
instructions on Removing Oil Boiler. Use wire brush,
brush soot and scale into combustion chamber where
it can be removed through burner opening.
B. Carefully vacuum debris from combustion chamber.
Inspect combustion chamber for signs of damage, i.e.
cracks.
C. In event combustion chamber is damaged, contact
quali
fi
ed service agent to replace immediately.
NOTICE
Do not overtighten bolts.
Periodic inspection
and tightening of tankless heater/
cover plate bolts reduce the risk of leaks. CAUTION: Do not
overtighten bolts.
MAINTENANCE PROCEDURES
Instructions For Removing Oil Burner
1.
Turn off power to boiler.
2.
Allow boiler to cool down.
3.
Remove three (3) 1/2" nuts from burner
fl
ange.
4.
Close oil valve.
See Figure 17 and Figure 18, Page 14 .
5.
Disconnect oil line from burner.
Recommend replacing nozzle at start of each heating
season.
Lubricate burner motor and circulator motor - if required -
with few drops of good grade of light motor oil. Do not over
oil.
Have quali
fi
ed service agent service burner and check
controls and electrodes for carbon or cracks in insulators.
Adjust burners to produce conditions shown in Start-up and
Adjustment of Oil Burner procedure.
Instructions For Replacing Oil Burner
1.
Reconnect oil line.
2.
Open oil valve.
See Figure 17, Page 14 and Figure 18,
Page 14 .
3.
Install and tighten three (3) 1/2" nuts on burner
fl
ange.
4.
Turn on power to boiler.
Regular Maintenance
• Inspect venting system at start of each heating season.
Check vent pipe from boiler to chimney for signs
of deterioration by rust or sagging joints. Repair if
necessary.
• Remove vent pipe at base of chimney or
fl
ue. Use mirror,
check for obstruction.
• Verify compliance with National Building Code of Canada,
or CAN/CSA A405.
• Operate lever of safety relief valve on boiler periodically
to verify that it is functioning properly. Open pressure
relief valve before water pressure exceeds 30 psi reading
on gauge. If pressure is exceeded and pressure relief
valve leaks water when boiler is operating at normal
pressures, replace immediately. Corrosion can build at
valve seat and prevent functioning as safety device.
