Alderlea T6 with blower and OAK

[Pechka]

Does anyone have the Alderlea T6 with the blower AND the OAK installed at the same time? Can you share your experience as to how this is done? I recently had the T6 installed but Im being told now (after the fact) that this specific model has a conflict between the OAK kit and the blower - you can have one or the other installed but not both. Apparently the T5 does not have this issue. Wish I knew this prior to purchasing the T6 model

If that's true it should be specified in your manual?

The blower might block a rear entrance of the outside air, I'll have to check. Regardless, I thought the OAK connection could also be done straight-up, underneath the stove just behind the ash pan.

... I just checked and it looks like an elbow could be attached so that the fresh air hose slipped under the blower. There's 4.25" under the blower so a 4" hose should squeeze under there.

Does anyone have a T6 with BOTH blower and OAK installed to send some pics of how this was achieved?
Im attaching a few photos I took today - as you can see with the blower installed it sits right in the way of the duct work that used to go into the stove

Here's what ChatGPT has to say on the subject:

Got it — rear exit straight through the wall is the hardest configuration on the T6 when a blower is added, and you’re not imagining things. On the Alderlea T6, the blower and the rear OAK port physically compete for the same space.

Here’s the straight, no-nonsense answer.

Short answer​

With a rear-exit OAK directly behind the stove, you generally cannot use the standard Pacific Energy blower and a straight rear OAK connection at the same time without modification.
The blower housing blocks the OAK collar location.

This is a known design conflict, not an installation mistake.

Why this happens (specific to your setup)​

• The rear OAK knockout feeds into the ashbox air plenum.
• The blower mounts across the back of that same plenum, sitting exactly where a 4" OAK pipe needs to connect.
• There is no factory offset adapter from Pacific Energy that clears the blower.
• The manual implies compatibility, but does not show a rear-exit OAK with blower installed, because it doesn’t physically fit as-is.

Installers usually discover this only after the blower is in hand.

In my book this is a FAIL on the PE side and the dealer who also was not aware of the issue prior to selling me the T6

Soooo?
How to plumb from outside air wall penetration to stove fresh air intake?

Ask ChatGBT

Perhaps

To me it looks like having the air come in at a 45 deg angle would work?

They changed the design to the detriment of this configuration. The older T6s had the OAK intake on the bottom of the plenum. That could still be done with a patch over the factory location. Or as stoveliker suggested, a modified 45º elbow could be made to work by making the male end into a connector by cutting alternate tabs on the end.
The other issue is the location and proximity of the exterior pipe. Is there room for a 3 inch 90º elbow there?

Does this flex pipe meet code? I'm thinking not but i have no idea.
He shows it at 2:43 time stamp.

Yes, the flex duct is ok to use on the OAK. That said, it's not exactly a kosher stove install. The hearth size is inadequate in front and to the side door side. Not sure about the clearance to the rear wall. It looks close.

Yes saw the stove install on small hearth.
Didn't know if both the flex and the tape were OK

Thinking about drawing air through my fireplace clean out that goes down to the basement floor. Will start a new thread if i start thinking more seriously about it.
