CHAPTER 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.
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.
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 220 VAC 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.
