Installation Instructions; System Start-Up - New Yorker CL3-105 Installation, Operating And Service Instructions

V: SYSTEM START-UP
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.
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
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.
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.
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.
