operation.
Electrical Wiring
The boiler, when installed, must be wired and electrically
bonded to ground in accordance with the requirements
of
the authority
having jurisdiction
or, in the absence of such
requirements,
with the National Electrical Code, ANSI/NFPA
70.
Tnstall a fused disconnect switch between boiler and
electrical panel in a convenient location. The wiring from high
temperature limit control should be secured to the boiler
jacket or gas piping to prevent an accidental disconnect from
controls.
All wiring to gas valves must be taped securely to the gas
supply lines or run in an appropriate conduit.
Adjust Thermostat Heat Anticipator
Suggested heat anticipator setting is.90 amps (set
accordingly).
Then follow instructions
packaged with
thermostat
for final adjustment,

operation.
When set above temperature
indicated on
thermometer,
boiler burners should ignite. Make certain
thermostat(s)
turns off boiler when room temperature
reaches selected setting and starts boiler operating when
room temperature
falls few degrees.
Finally, set thermostat
for desired temperature.
Special
conditions in building and location of thermostat
will
govern this setting.
Stage Firing Multiple
Base Boilers
Multiple base hot water boilers are ideal for stage firing.
Many controls are available for sequencing or stage
firing multiple base hot water boilers. We offer Argo
AMB Outdoor Reset Stage Fire Control Packages that will
sequence up to eight bases, with lead boiler rotation,
adjustable reset ratio, set point boiler rotation,
and
microprocessor
control. This control will fire bases as
required to maintain supply water temperature
at a desired
set point, which is automatically
varied based on outdoor
air temperature.
Consult boiler manufacturer
for more
information.
Thermostat
Installation
The thermostat location has an important effect on the
operation of the boiler system. Be sure to follow the
instructions included with the thermostat. Locate the
thermostat about 5 feet above the floor on an inside wall. It
should be sensing average temperature.
Keep thermostat(s) at desired room temperature. If windows
are to be opened or heat is not needed, set thermostat(s)
pointer to a lower setting.
