System Start-Up - New Yorker AP-490U Installation, Operating And Service Instructions

VII: 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.
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. 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 6A, and 6B, 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.
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.
Note - If make-up water line is equipped with pressure
reducing valve, system will automatically fill to 12
psig.
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.
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.
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 CONTROL, 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.
LUBRICATION. Follow instruction on burner and
circulator label to lubricate, if oil lubricated. Most
motors currently used on residential type burners
employ permanently lubricated bearings and thus DO
NOT require any field lubrication. Water lubricated
circulators DO NOT need field lubrication.
E.
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 Oil Primary
Control. Hold button for ten (10) seconds and
release to reset primary control.
3. WATER 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.
