Air Intake Requirements
The fireplace requires air intake(s) to supply combustion air to the firebox. Requirements for the air
intake(s) are listed below:
The air intake(s) must be routed to the exterior of the structure or to an area that freely conveys
air to the outside. Do not draw air from a garage or other area that may be subject to fumes or
airborne particles.
Air Intake Ducts
Must use 6” or 8” UL 181 Duct (Class 1 or Class 0 – capable of negative pressure reading of 1”
water column). Consult your local building department for details on duct installation and
requirements in your area. We strongly recommend the use of insulated ducting such as Master
Flow™ which is carried at Home Depot™ and other stores that carry HVAC products (insulated
ducting is typically R4.2 or greater with vapor barrier). Insulated ducting prevents condensation
from forming on the exterior of the ducts or fireplace. This is especially important when the ducts
are routed through heated areas that may be subject to humidification.
The chart below details air intake maximum height and length. If the intake falls within the
“Standard Installation” range shown below, the air intakes may be 6” diameter. If the intake falls
within the shaded range, you must contact Travis Industries to verify the installation and
determine the correct configuration (you may need to use 8” diameter duct).
Connect the air intake ducts to the fireplace, damper (if used), and termination using a suitable
securing method (tape, silicone, etc.). Long duct runs must be properly secured.
Each air intake termination must be positioned so it does not become blocked by snow,
vegetation, or other material. It must be installed with a suitable cap that prevents water or debris
from entering. The termination (and damper, if used) must be positioned so it may be accessible
for service and verification. If air intake is positioned on a wall, make sure to slope the intake
down slightly to prevent water intrusion.
