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.
See Section 1.4 for important information regarding installation of units within the
Commonwealth of Massachusetts.
IMPORTANT!
This Guide 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 may operate under a positive pressure and therefore
must be completely sealed to prevent leakage of combustion products into living spaces.
•
Electrical voltages of 120, 208, 460, 575 AND 24 volts AC 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 three-pole switch 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.
