READ THIS ENTIRE MANUAL before attempting
installation, start-up, or service. Improper
installation, adjustment, alteration, service,
or maintenance may cause serious property
damage, personal injury, or death.
DO NOT DISCONNECT PIPE FITTINGS on
the boiler or in the heating system without first
verifying that the system is cool and free of
pressure and that your clothing will protect you
from a release of hot water or steam. Do not rely
solely on the boiler’s temperature and pressure
gage when making this judgment.
USE PROPER PERSONAL PROTECTION
EQUIPMENT
when servicing or working near the
boiler. Materials of construction, flue products,
and fuel contain alumina, silica, heavy metals,
carbon monoxide, nitrogen oxides, and/or
other toxic or harmful substances that can are
hazardous to health and life and that are known
to the State of California to cause cancer, birth
defects, and other reproductive harm.
INSTALL ALL GUARDS
, cover plates, and
enclosures before operating the boiler.
SIZE THE BOILER PROPERLY
relative to the
design heat load or, if using domestic hot water
priority, the peak hot water load, whichever
is larger. A grossly oversized boiler will cycle
excessively and this will lead to premature failure
of the boiler and its components. Our warranty
does not apply to damage from excessive cycling.
ADHERE TO ALL LOCAL CODE
REQUIREMENTS.
Contact your local code
inspector prior to installation. In the absence of a
local code, adhere to the
National Fuel Gas Code
ANSI Z223.1/NFPA 54
.
ALL WIRING
must comply with the
National
Electrical Code
ANSI/NFPA 70.
