Where the two vents go

Placement matters, but it's your call. Here's what we recommend: put the fresh-air intake low, near the stove, and the mechanical exhaust on the opposite wall, under the top bench (about halfway up) — that setup pulls used air across and down over you before it leaves. That said, install both vents wherever you see fit for your room and layout.

The install, step by step

a

Mark your two vent locations

Following the placement you've chosen (see our recommendation above), mark the center of each hole on the interior wall. Two checks before you cut: if your sauna is stick-frame construction, make sure the spot you're drilling doesn't land on a wall stud, and confirm there's clear space directly outside the exhaust hole for the fan (9) to mount.

b

Drill through the wall

Chuck the 4" hole saw (5) into your drill. Start each cut from the inside so the interior face stays clean, then finish from the outside so you don't blow out the siding. When you're through, pop the wood core out of the saw and set it aside.

Clear the insulation in the opening

If your walls are insulated, push the insulation aside inside the hole so the duct has a clean, unobstructed path straight through the wall.

Run the ducting through the wall

Feed the flex ducting (1) through the exhaust opening out to the fan. If the run is short, add the second flex duct (8) and join the two, sealing the seam with the aluminum tape (6).

e

Mount the exhaust fan outside

On the exterior wall, mount the fan (9) with the mounting hardware (12), and connect its pre-fitted elbow to the flex ducting (1), sealing the connection with the aluminum tape (6). Mounting outside keeps the electric fan completely clear of the sauna's heat — exactly where you want it.

Fit the interior vent covers

Set a louvered vent cover (3) over each opening and fasten it with the screws (2 or 7). Where the cover meets the flex ducting, secure and seal it with the aluminum tape (6). The intake vent gets a cover too — it has no fan, it's just the fresh-air inlet.

Wire up the controller

You can mount the fan speed controller (10) either inside the hot room or outside — wherever's easiest to reach. Plug the fan's lead into the controller, using the extension cable (11) to reach your chosen spot. If you want the controller inside the hot room, drill a small hole through the wall near the exhaust fan opening and run the extension cord (11) through the wall to connect it to the controller. Tidy the cable run with the velcro strap (14). The manual (13) covers the controller's settings if you want to dial in a temperature trigger.

h

Weatherproof the exterior fan

The fan (9) is electric, so out in the weather it needs protection from rain, snow, and sun. Enclose the exterior fan and ducting — the Wood Cover version of the kit is a hand-built housing that does this in one piece, or you can build your own cover.

i

Power it up and test

Plug the fan into a nearby outlet or extension cord and you're running the same day, or hardwire it for a cleaner finish. Turn the controller (10) up and check that air is moving — you should feel the intake pulling fresh air in low by the stove. Run a full session and you'll notice it immediately: clearer air, a clearer head, and heat that feels even from your feet to your head.
