IV. 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. Conrm 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.
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 4, to
remove air from system when lling:
1. Close full port ball valve in boiler system piping.
2. Isolate all zones by closing zone valves or shut-off
valves in supply and return of each zone(s).
3. Attach a hose to vertical purge valve in boiler
system piping.
(Note - Terminate hose in ve gallon bucket at a
suitable oor drain or outdoor area).
4. Starting with one zone at a time, open zone valve or
shut-off valve in boiler supply and return piping.
5. Open purge valve.
6. Open shut-off valve in cold water supply piping
located between the air scoop and expansion tank.
7. Allow water to overow from bucket until discharge
from hose is bubble free for 30 seconds.
8. 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.
9. Close purge valve, continue lling the system until
the pressure gauge reads 12 psi. Close shut-off valve
in cold water supply piping.
WARNING
All boilers equipped with burner a 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 ring of burner outside the combustion chamber. Be sure to tighten swing door
fastener completely when service is completed.
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 relief valve.
NOTICE
If make-up water line is equipped with pressure
reducing valve, system will automatically ll to 12
psi. Follow ll valve manufacturer's instructions.
10. Open full port ball valve in boiler system piping.
11. Remove hose from purge valve.
12 Conrm 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 lled
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. Hold button for one (1) second and
release to reset primary control.
3. BOILERS WITHOUT TANKLESS HEATERS
are equipped with an Intelligent Oil Boiler Control
(Boiler Control). The 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. This temperature may be varied
to suit the installation requirements.
HIGH LIMIT DIFFERENTIAL is factory
programmed at 15°F and is adjustable between 10°F
and 30°F.
4. 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
