Installation (for qualified installers only) 33© Travis Industries 9/25/17-1468 MaestroAir Intake RequirementsThe fireplace requires air intake(s) to supply combustion air to the firebox. Requirements for the airintake(s) are listed below: The air intake(s) must be routed to the exterior of the structure or to an area that freely conveysair from the outside. Do not draw air from a garage or other area that may be subject to fumes orairborne particles.Air Intake Ducts Must use 8” UL 181 Duct or better (Class 1 or Class 0 – capable of negative pressure reading of1” water column). Consult your local building department for details on duct installation andrequirements in your area. We strongly recommend the use of insulated ducting such as MasterFlow™ which is carried at Home Depot™ and other stores that carry HVAC products (insulatedducting is typically R4.2 or greater with vapor barrier). Insulated ducting prevents condensationfrom forming on the exterior of the ducts or fireplace. This is especially important when the ductsare 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 theshaded range, you must contact Travis Industries to verify the installation and determine thecorrect configuration. Connect the air intake ducts to the fireplace, damper (if used), and termination using a suitablesecuring method (tape, silicone, etc.). Long duct runs must be properly secured. We recommend the use of intake dampers. If you do not use dampers, we recommend you routethe intake damper wires to the intake location so dampers may be installed at a later time. 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 debrisfrom entering. The termination (and damper, if used) must be positioned so it may be accessiblefor service and verification. If air intake is positioned on a wall, make sure to slope the intakedown slightly to prevent water intrusion. The air intake termination must be flashed and sealed to meet local building code requirements.
