Unpack Boiler; Water Piping And Trim - New Yorker CG20D Installation, Operating And Service Instructions

II. Unpack Boiler
CAUTION
Do not drop boiler. Do not bump boiler jacket
against floor.
A.
Move boiler to approximate installed position.
B.
Remove all crate fasteners.
C.
Lift outside container and remove with all other
inside protective spacers and bracing. Save two of the
wooden slats from the container sleeve for use in Steps
E and F.
III. Water Piping and Trim
WARNING
Failure to properly pipe boiler may result in
improper operation and damage to boiler or
building.
A.
Design and install boiler and system piping to
prevent oxygen contamination of boiler water.
Oxygen contamination sources are system leaks
requiring addition of makeup water, fittings, and oxygen
permeable materials in distribution system. Eliminate
oxygen contamination by repairing system leaks,
repairing fittings, and using nonpermeable materials in
distribution system.
B.
Install circulator with flanges, gaskets and bolts
provided. Five foot long circulator harness allows
circulator to be mounted on supply or return. Connect
harness to circulator and secure any excess conduit.
C.
Install Safety Relief Valve. See Figure 1. Safety Relief
Valve must be installed with spindle in vertical position.
WARNING
Safety relief valve discharge piping must be piped
near floor to eliminate potential of severe burns.
Do not pipe in any area where freezing could
occur. Do not install any shut-off valves.
D.
Connect system supply and return piping to boiler.
Refer to Figure 3. Also consult Residential Hydronic
Heating Installation and Design I=B=R Guide.
Maintain minimum ½ inch clearance from hot water
piping to combustible materials.
D
. Remove all boiler hold-down fasteners.
E.
Tilt the boiler to one side and slide a wooden slat under
the two raised feet.
F.
Tilt the boiler to the other side and slide another
wooden slat under the two raised feet.
G.
Slide the boiler forward or backward off the skid using
the two wooden slats as runners.
H.
Move boiler to its permanent location.
E.
Space heating and domestic water heating with the
New Yorker Link SL™ indirect water heater. Install
the New Yorker Link SL™ indirect water heater as a
separate heating zone. Refer to the New Yorker Link
SL™ Indirect Water Heater Installation, Operating and
Service Instructions for additional information.
F.
If boiler is used in connection with refrigeration
systems, boiler must be installed with chilled medium
piped in parallel with the heating boiler using
appropriate valves to prevent chilled medium from
entering boiler. See Figure 4. Also consult Residential
Hydronic Heating Installation and Design I=B=R
Guide.
G.
If boiler is connected to heating coils located in
air handling units where they may be exposed to
refrigerated air, boiler piping must be equipped with
flow control valves to prevent gravity circulation of
boiler water during operation of cooling system.
H.
Use a boiler bypass if the boiler is to be operated
in a system which has a large volume or excessive
radiation where low boiler water temperatures may be
encountered (i.e. converted gravity circulation system,
etc.).
Remove circulator and install pipe tee between
circulator and boiler return along with second tee in
supply piping as shown in Figure 3. Bypass should be
same size as the supply and return lines with valves
located in bypass and supply outlet as illustrated in
Figure 3 in order to regulate water flow to maintain
higher boiler water temperatures.
Set by-pass and boiler supply valves to half throttle
position to start. Operate boiler until system water
temperature reaches normal operating range.
