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 rst 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, ue 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.
THIS INSTALLATION IS NOT COMPLETE until
the front air dam is installed (See Figure 2-a).
Product performance will be negatively affected if
the front air dam is not installed which can cause
serious property damage, personal injury or death.
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.
1. Installation must conform to requirements
of authority having jurisdiction or in the
absence of such requirements, with the
National Fuel Gas Code, ANSI Z223.1/NFPA
54, and/or the Natural Gas and Propane
Installation Code, CAN/CSA B149.1.
2. Where required by authority having
jurisdiction, the installation must conform to
Standard for Controls and Safety Devices
for Automatically Fired Boilers, ANSI/ASME
CSD-1.
3. A boiler installed above radiation level or
as required by authority having jurisdiction,
must be provided with a low water cutoff
device at time of installation. Use IQ Low
Water Cutoff Kit listed in Appendix I. Locate
sensor as shown in Figure 6-b. Wire as
shown in Figure IW-1.
4. ALL WIRING must be in accordance with
requirements of authority having jurisdiction
or, in the absence of such requirements, with
the National Electrical Code, ANSI/NFPA 70,
and/or the Canadian Electrical Code Part 1,
CSA C22.1, Electrical Code.
INSTALLING CONTRACTOR IS RESPONSIBLE
to verify that all controls are correctly installed
and are operating properly when installation is
complete.
1. Limit Sensor Fully inserted.
Failure to properly install limit sensor may
result in property damage, personal injury
or loss of life due to elevated operating
temperatures and/or pressures.
2. Safety relief valve installed in supply water
manifold.
3. Blocked vent switch installed on edge of
canopy/draft diverter.
