How to Wire
Ensure power is turned off to boiler.
Locate the LWCO jumper wire in the factory wiring
harness. Remove the jumper wire and install
the LWCO wiring from LWCO Model 1100-H4
(P/N 100592-01) into the plug of the PVG factory
wiring.
How to Test
Shut off fuel supply. Lower water level until water
level is BELOW the LWCO. Generate a boiler demand
by turning up thermostat. Boiler should not attempt to
operate. Increase the water level by filling the system.
The boiler should attempt to operate once the water
level is above the LWCO.
NOTICE
Ensure the location of the LWCO in the piping will
allow for connection of the LWCO wiring harness
to the factory wiring of the PVG.
C.
Connect system supply and return piping to
boiler. See Figures 11 and 12. Maintain minimum ½
inch clearance from hot water piping to combustible
materials.
NOTICE
U.S. Boiler recommends sizing the system
circulator to supply sufficient flow (GPM) to allow a
0°F temperature differential in the system. When
sizing the system circulator, the pressure drop of
all radiators, baseboard and radiant tubing and all
connecting piping must be considered.
D.
Install circulator with flanges,
gaskets and bolts
provided. Circulator harness allows circulator to be
mounted on supply or return. Connect harness to
circulator and secure any excess conduit.
E.
Install supply manifold, pressure/temperature gauge
and pressure relief valve.
See Figure 10A. Pressure Relief Valve must be installed
with spindle in vertical position. Installation of the
relief valve must comply with the ASME Boiler and
Pressure Vessel Code, Section IV.
Figure 10: Recommended Piping for Combination
Heating & Cooling (Refrigeration) System
WARNING
Pressure relief valve discharge piping must be
piped such that the potential of severe burns
is eliminated. DO NOT pipe in any area where
freezing could occur. DO NOT install any shut-off
valves, plugs or caps. Consult Local Codes for
proper discharge piping arrangement.
F.
Space heating and domestic water heating with
Alliance™ SL water heater. Install Alliance™ SL water
heater as a separate heating zone. Refer to Alliance™
SL Installation, Operating and Service Instructions for
additional information.
G.
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 10.
H.
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.
I.
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.).
