SKG3 Gas Fired Humidifier
Installation Instructions and User Manual
23
Stage 6 – Combustion Air Installation
CAUTION
: Combustion and room ventilation air must conform to local codes and
regulations and to section 7.2, 7.3 or 7.4, Air for Combustion and Ventilation of the
current ANSI Z223.1 ‘’National Fuel Gas Code’’ or CAN/CSA-B149.
CAUTION
: Air for combustion MUST NOT be contaminated by halogens, ammonia,
bromides, chlorides, fluorides, iodides or dust. Excessive exposure of humidifier to
these contaminants will result in performance related problems. A humidifier that
may be operated in toxic environments must be equipped with ducted combustion air
installation.
CAUTION
: The operation exhaust of fans such as ventilation fans or other
combustion appliances can create a negative pressure condition on the humidifier.
Adequate air supply must be provided for the ventilation devices, in addition to that
required by the humidifier.
Any installation work must be carried out by suitably qualified personnel.
With the exception of ducted combustion air installation, do not locate units in tightly
sealed rooms or small compartments.
Combustion and ventilation air must be supplied through one permanent low-level
and one permanent high-level opening communicating directly with the outside air.
Air intake(s) location must be at a sufficient height above ground level to prevent
blocking by accumulated debris.
Supply air intake vent(s) must be equipped with a weather cap and bird screen, in
order to prevent gusts of wind or water from entering, preventing mold build up or
leakage in the ducts.
The SKG3 Steam Humidifier has filtered air openings through the front door.
Do not block or obstruct the air openings of the humidifier.
The humidifier is factory adjusted for correct performance. Do not alter throttle
setting or restrict blower combustion air inlet.
