Safety precautions
• Installation must conform to the requirements of the authority having
jurisdiction or, in the absence of such requirements, must conform to:
In the United States: The National Fuel Gas Code, ANSI Z223.1
(latest edition).
In Canada: Local plumbing or waste water codes and other
applicable codes and with the current code CAN/CGA-B149.1,
“Installation Code for Natural Gas Burning Appliances and
Equipment,” or CAN/CGA-B149.2, “Installation Code for Propane
Burning Appliances and Equipment.”
In Europe: The National Gas Safety (Installation & Use) Regulations.
• Do not install in potentially explosive or flammable atmospheres
laden with grain dust, sawdust, or similar airborne materials.
• Installation of humidifier in high humidity or salt water atmospheres
causes accelerated corrosion, reducing the normal life-span of the
unit.
• To prevent premature heat exchanger failure, do not locate any gas-
fired unit in areas where chlorinated, halogenated, or acid vapors are
present in the atmosphere.
• Locate the humidifier in an area clear of combustible materials,
gasoline, and other flammable vapors and liquids.
• With the exception of sealed combustion units, do not locate units
in tightly sealed rooms or small compartments without provision for
adequate combustion air and venting. Room air combustion must be
supplied through a minimum of two permanent openings in the wall,
with at least one near the bottom. See the table and information on
Page 30 for additional information.
• Remove all shipping brackets and materials before operating the
humidifier.
• Do not locate humidifier in a negative pressure space. Combustion
products could be suctioned from the venting.
• Humidifier flue gases must be vented to the outside atmosphere.
• Power supply disconnect switch must be in the off position while
making wiring connections to prevent electrical shock and equipment
damage. All units must be wired in strict accordance with the wiring
diagrams furnished with this unit.
• Turn off all gas while installing the gas piping and manual shutoff
valve for the humidifier.
• The appliance and its individual shut-off valve must be disconnected
from the gas supply piping system during any pressure testing of that
system at test pressures exceeding 0.5 psig (3.5 kPa).
