VERSATILITY & SIMPLICITY

Concentric Flex can be used as a cost-effective alternative to 45° elbows when offsetting around an obstacle

such as a stud, joist, or truss. It allows you to put the vent EXACTLY where you need it, and in a hurry. Aside

from speeding up installation, using this approach can also help to minimize the number of joints between

pipe sections. Aside from a modest savings on parts, you will also save on installation time.

We have all been there. The customer wants the fireplace positioned in such a way that the outlet always

seems to line up with an obstacle – like a wall stud, electrical wiring, or vent stack for plumbing. No problem!

DirectVent Pro Concentric Flex allows you to quickly adjust the positioning of the vent to hit the desired stud

space in any up & out or cross-corner installation. The same is true for a joist or truss in vertical installations.

Single-offset? Double-offset? Simply adjust a length of DVP Concentric Flex to suit the application.

Key features and benefits:

FULLY COMPATIBLE - DVP Concentric Flex is fully compatible with DirectVent Pro. This gives you the best of

both worlds – the robust, long-lasting, professional reputation of our rigid system combined with the infinite

convenience of concentric flex when you need it, where you need it.

TWIST-LOCK CONNECTION - Our concentric flex features the same twist-lock you already know. This makes

assembly easy on fireplaces that are already equipped with a twist-lock outlet. No need for messy sealants or

screws here*. This also allows you to use concentric flex in combination with other DirectVent Pro parts you

already have in the truck or on the shelf.

FACTORY-INSTALLED SPACER - DVP Concentric Flex comes with a factory-installed spacer. This eliminates the

fear associated with hot-spots and compromised clearances-to-combustibles. With field-assembled product,

spacers can be overlooked or misplaced at the wrong intervals. Spacers can also slip out of place. Not only is

our spacer firmly attached, it runs continuously through each length from one end to the other. This results in

a consistent air gap between the inner flue and outer air intake.

UNIQUE OVERLAPPING COLLAR DESIGN – Unlike systems offered by competitors, there is no need to

improvise when attempting to attach flex on the downstream end of the vent. Simply twist-lock the pipe

together as you normally would, then pull the outer flex up into place, and fasten the two overlapping collars

together using supplied screws. Quick, simple, and easy with no compromises.

THREE CONVENIENT LENGTHS TO CHOOSE FROM – DirectVent Pro Concentric Flex is available in 3-foot,

5-foot, and 10-foot lengths for use with DirectVent Pro 46DVA and 58DVA venting. Each length ships from the

factory compressed within a compact box. The smaller packaging takes up less space on the shelf and in the

truck during transport. At the jobsite, the inner and outer lengths are easily stretched independently to your

exact requirements.

CONSTRUCTION – The inner and outer flex on DirectVent Pro Concentric Flex is made with two-ply aluminum.

It is designed to withstand the high heat of exhaust emitted from any approved gas fireplace. The outer’s role

is to conduct combustion air and is robust enough to meet all impact and puncture test requirements.
