Stage 7 -Flue Gas Venting Connection - Neptronic SKG3 Series Installation Instructions Manual

CAUTION : For safe and efficient operation of the SKG3 Steam Humidifier, flue
!
gases (product of combustion) MUST be evacuated through a dedicated flue gas
venting system to the outside air.
CAUTION : Flue Gas venting should conform to local codes and regulations, and to
current ANSI Z223.1, ''National Fuel Gas Code'' or CAN/CSA-B149.
SKG3 Steam Humidifier MUST be installed with a listed ''BH vent'' for positive
pressure and condensation. The vent must be fabricated of AL29-4C stainless steel
and be air and water tight.
Do not vent the SKG3 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 pipe passing through floors, ceilings, and walls MUST be
installed with proper clearances to combustible material, 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 system in accordance with vent manufacturer's instructions.
Flue gas venting pipe MUST be free of any restriction, obstruction. Flue gas venting
pipe diameter MUST be the same as the SKG3 flue gas connector.
Do not use unlined masonry or concrete chimney as a flue gas venting system.
Flue gas venting system should not extend into, or pass through, any air duct.
Installation of the flue gas venting pipe should be as direct as possible, with a
minimum number of turns or elbows.
Do not insulate flue gas venting pipe exposed to outdoor weather condition.

Flue Gas Venting
Neptronic® SKG3 Steam Humidifier is a fan assisted non condensing positive
pressure flue gas appliance.
Specification
Maximum flue gas temperature: Ambient 390˚F (
Maximum flue gas venting pipe length: 100' – 60'' x (total number of 90˚elbow)
Flue gas venting pipe diameter MUST be the same as the SKG3 flue gas connector.
Minimum flue gas venting pipe upward gradient should be ¾'' (20mm) in 40'' (1m)
horizontal run or as per flue gas venting manufacturer's instructions.
Neptronic® SKG3 Steam Humidifier is a non condensing appliance. However, its
high efficiency may cause condensation in the flue gas venting.
Condensate drip tee should be installed, as per flue gas venting manufacturer's
instructions.
Flue Gas
Proper flue gas terminal should be installed to prevent back flow or any other
outside weather condition that may affect proper operation of the SKG Humidifier.
Terminal
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 40'' (1m) above the roof top, and
24'' (0.6m) above any ridge located within 10 feet (3m) from the terminal.
