A.

 

ALWAYS  INSPECT  INSTALLATION  

BEFORE STARTING  BURNER.

1.  Verify that the venting, water piping, oil piping, and 

electrical system are installed properly.  Refer to 

Installation Instructions contained in this manual.

2.  Confirm all electrical, water and oil supplies are 

turned off at the source and that the vent is clear 

from obstructions.

WARNING

Completely read, understand and follow all 

instructions in this manual before attempting 

start up.

B.

 

FILL  HEATING  SYSTEM  WITH  WATER.

NOTICE

It is important, especially in a steam system, to 

properly remove the oil and dirt from the system.  

Failure to clean the system can result in erratic 

water lines and surging.

 

CLEAN  HEATING  SYSTEM  if boiler water or 

condensate return water is dirty or if erratic water lines 

or surging exist after a few days of boiler operation.

 

Refer to Maintenance and Service Instructions Section 

of this manual for proper cleaning instructions for 

steam and water boilers.
1.  STEAM  BOILERS — Fill boiler to normal water 

line. Refer to Figures 1C and 1D.

2.  HOT  WATER  BOILERS.  Fill entire heating 

system with water and vent air from system.  Use 

the following procedure on a series loop or multi-

zoned system installed as per Figures 11A, and 11B, 

to remove air from system when filling:

a.  Close full port ball valve in boiler system piping.
b.  Isolate all zones by closing zone valves or shut-

off valves in supply and return of each zone(s).

c.  Attach a hose to vertical purge valve in boiler 

system piping.

(

Note

 - Terminate hose in five gallon bucket at a 

suitable floor drain or outdoor area).

d.  Starting with one zone at a time, open zone valve 

or shut-off valve in boiler supply and return 

piping.

WARNING

All boilers equipped with burner swing door have a potential hazard which can cause severe property damage, 

personal injury or loss of life if ignored.  Before opening swing door, turn off service switch to boiler to 

prevent accidental firing of burner outside the combustion chamber.  Be sure to tighten swing door fastener 

completely when service is completed.

V:  SYSTEM START-UP

e.  Open purge valve.
f.  Open shut-off valve in cold water supply piping 

located  between the air scoop and expansion 

tank.

g.  Allow water to overflow from bucket until 

discharge from hose is bubble free for 30 

seconds.

h.  When zone is completely purged of air, close 

zone valve or shut-off valve.  Open zone valve to 

the next zone to be purged.  Repeat this step until 

all zones have been purged.  At completion, open 

all zone valves.

i.  Close purge valve, continue filling the system 

until the pressure gauge reads 12 psi. Close shut-

off valve in cold water supply piping.

WARNING

The maximum operating pressure of this boiler 

is posted on the ASME Data Label located on the 

top of the boiler.  Never exceed this pressure.  DO 

NOT plug safety or relief valve.

NOTICE

If make-up water line is equipped with pressure 

reducing valve, system will automatically fill to 12 

psi.  Follow fill valve manufacturer's instructions.

j.  Open full port ball valve in boiler system piping.
k.  Remove hose from purge valve.

l.  Confirm that the boiler and system have no water 

leaks.

C.

 

CHECK  CONTROLS,  WIRING  AND  

BURNER  

to be sure that all connections are tight and 

burner is rigid, that all electrical connections have been 

completed and fuses installed, and that oil tank is filled 

and oil lines have been tested.

D.

 

ADJUST CONTROL SETTINGS

  with burner 

service switch turned “ON”.
1.  SET  ROOM  THERMOSTAT  about 10°F below 

room temperature.

2.  PRESS  RED  RESET  BUTTON  on front 

of  burner cover (Beckett, Riello burners) or Oil 

Primary Control with burner cover removed. Hold 

button for one (1) second and release to reset 

primary control.
