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.
