SECTION 1: SAFETY PRECAUTIONS
1.1 WARNINGS & CAUTIONS
Installers and operating personnel MUST, at all times, observe all safety regulations. The
following warnings and cautions are general and must be given the same attention as specific
precautions included in these instructions. In addition to all the requirements included in this
AERCO Instruction Manual, the installation of units MUST conform with local building codes, or,
in the absence of local codes, ANSI Z223.1 (National Fuel Gas Code Publication No. NFPA-54)
for gas-fired boilers and ANSI/NFPASB for LP gas-fired boilers. Where applicable, the
equipment shall be installed in accordance with the current Installation Code for Gas Burning
Appliances and Equipment, CSA B149.1, and applicable Provincial regulations for the class;
which should be carefully followed in all cases. Authorities having jurisdiction should be
consulted before installations are made.
IMPORTANT!
This Instruction Manual is an integral part of the product and must be maintained in legible
condition. It must be given to the user by the installer and kept in a safe place for future
reference.
WARNING!
•Do not use matches, candles, flames, or other sources of ignition to check for gas leaks.
•Fluids under pressure may cause injury to personnel or damage to equipment when
released. Be sure to shut off all incoming and outgoing water shutoff valves. Carefully
decrease all trapped pressures to zero before performing maintenance.
•Before attempting to perform any maintenance on the unit, shut off all gas and electrical
inputs to the unit.
•The exhaust vent pipe of the unit operates under a positive pressure and therefore must be
completely sealed to prevent leakage of combustion products into living spaces.
•Electrical voltages UP TO 120 VAC (BMK 750 – 2000) OR 208, 460 OR 575 VAC (BMK 2500 –
6000) may be used in this equipment. Therefore the cover on the unit’s power box (located
behind the front panel door) must be installed at all times, except during maintenance and
servicing.
•A single-pole switch for single phase units and three-pole switch for three phase units must
be installed on the electrical supply line of the unit. The switch must be installed in an easily
accessible position to quickly and safely disconnect electrical service. Do not affix switch to
unit sheet metal enclosures.
CAUTION!
•Many soaps used for gas pipe leak testing are corrosive to metals. The piping must be
rinsed thoroughly with clean water after leak checks have been completed.
•DO NOT use this boiler if any part has been under water. Call a qualified service technician
to inspect and replace any part that has been under water.

1.2 EMERGENCY SHUTDOWN
If overheating occurs or the gas supply fails to shut off, close the manual gas shutoff valve
(Figure 1-1) located external to the unit.
NOTE:
The Installer must identify and indicate the location of the emergency shutdown manual gas
valve to operating personnel.
Figure 1-1: Manual Gas Shutoff Valve
In addition, to ensure safety an emergency shutdown procedure that addresses the following
points should be designed and implement at the site:
•For automatically operated unattended boilers located in a boiler room, provide a manually
operated remote shutdown switch or circuit breaker located just inside or outside each boiler
room door. Design the system so activation of the emergency shutdown switch or circuit
breaker will immediately shut off the fuel supply to the unit(s).
•For automatically operated unattended boilers in a location other than a boiler room, provide a
manually operated remote shutdown switch or circuit breaker marked for easy identification at a
location readily accessible in the event of boiler mis-operation.
•Design the system so activation of the emergency shutdown switch or circuit breaker will
immediately shut off the fuel.
•For boilers monitored and/or operated from a continuously occupied control room, provide an
emergency shutdown switch in the control room that is hard-wired to immediately shut off the
fuel upon activation.
1.3 PROLONGED SHUTDOWN
If there is an emergency, turn off the electrical power supply to the AERCO boiler and close the
manual gas valve located upstream from the unit. The installer must identify the emergency
shut-off device.
If the unit is being shut down for an extended period of time, such as a year or more, complete
the instructions in Section 8.12: Shutting Boiler Down For Extended Period in the Benchmark
PLATINUM-Edge: Operation-Service Manual (OMM-0137 , GF-211).
When returning a unit to service after a prolonged shutdown, it is recommended that the
instructions in Section 4: Initial Startup Procedures and Section 5: Safety Device Testing of the
Benchmark PLATINUM-Edge: Operation-Service Manual (GF-211) be performed to verify
that all system-operating parameters are correct.
