Stage 7 – Flue Gas Venting Connection
CAUTION
For safe and efficient operation of the SKGE3 Steam Humidifier, flue gases (product
of combustion) MUST be evacuated through a dedicated flue gas venting system to
the outside air.
Flue gas venting must conform to local codes and regulations.
Do not vent the SKGE3 Steam Humidifier into another venting system serving
another appliance. The humidifier must be vented by its own approved/listed flue
system.
Any flue gas venting pipes passing through floors, ceilings, and walls MUST be
installed with proper clearances to combustible materials, and MUST be fire stopped
according to local codes and regulations.
Use only roof and wall penetration systems recommended by the flue gas venting
system manufacturer.
Install flue gas venting systems in accorda
nce with vent manufacturer’s instructions.
Flue gas venting pipe MUST be free of any restrictions or obstructions. The flue gas
venting pipe diameter MUST be same as the SKGE3 flue gas connector.
Do not use unlined masonry or concrete chimney as a flue gas venting system.
The flue gas venting system must not extend into, or pass through, any circulation air
duct or plenum.
Installation of the flue gas venting pipes must be as direct as possible, with a
minimum number of turns or elbows.
Do not insulate flue gas venting pipes exposed to outdoor weather condition.
Ensure that the flue connection to the humidifier is air tight. Failure to do this will
result in damage due to moist flue gases condensing.

outside weather condition that may affect proper operation of the SKGE3 Humidifier.
Distances from the flue gas venting terminal to adjacent public walkways, buildings,
and any open able windows or building opening MUST conform to local codes and
regulations.
Flue gas terminal MUST be at sufficient height above the ground level to prevent
blocking by accumulated debris.
Building materials MUST be protected from degradation by flue gases.
Vertical flue gas terminal MUST extend at least 1 meter above the roof top, and 0.6
meter above any ridge located within 3 meters from the terminal.
