VI: SYSTEM START-UP
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 to properly remove the oil and dirt
from the system. Failure to clean the system can
result in clogged air vents, circulator damage and
seized zone valves.
CLEAN HEATING SYSTEM if boiler water is
dirty.
Refer to Maintenance and Service Instructions Section
of this manual for proper cleaning instructions for water
boilers.
1. 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 Figure 6 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 supply piping up stream from the full
port ball valve.
(
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.
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 valve 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 Rating Label located on the front
of the boiler. Never exceed this pressure. Do not
plug 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.
m. It may be necessary to clean the air vent
assembly after a few days of operation.
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 burner primary
control, hold for one second and release to reset the
control.
3. WATER BOILERS WITH TANKLESS
HEATERS are equipped with a Warm Start
Intelligent Oil Boiler Control (Warm Start Boiler
Control). The Warm Start Boiler Control is factory
programmed with a High Limit setpoint of 180°F.
The High Limit setpoint is adjustable between
140°F and 240°F. High Limit Differential is factory
programmed at 10°F. Additionally, the Warm Start
Boiler Control is factory programmed with a Low
Limit setpoint of 110°F. The Low Limit setpoint
is adjustable between 110°F and 220°F. These
temperatures may be varied to suit the installation
requirements.
