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.
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 or 220 VAC, 1 phase (BMK 750 – 2000), 208-230 or 380 or
460 VAC, 3 phase (BMK 2500/3000) 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 (on 120 VAC units) or three-pole (on 208-230, 380 and 460 VAC units) switch
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.
