Harman XXV Installed

SoCal65 · Oct 19, 2006

I got my Harman XXV installed yesterday. All is well! No squeeling or other undocumented noises. I am busy experimenting with the thermostat, the therm wire location, and my central heating fan "fan only". I have my XXV installed on the hearth. My zero clearance fireplace "worth zero dollars" is sealed off with "stove black" sheet metal.

Two questions.
What is the High/Low switch for? It is just inside the control panel door, on the the stove not on the control panel. Mine is currently set to high.

Is it normal to have a slight smoke smell after the stove ignites itself? It goes away right after I get a flame.

Thanks

The Hi-Low switch allows you to lower the voltage to the distribution blower, thus less air noise from the blower. Nice feature if the stove is in the same room as the dreaded TV.
I would suggest checking all the seams & joints on the pipe for any smoke leakage during the ignition cycle, you should not be able to smell smoke at anytime. Start the stove when the room is dark and use a flashlight to inspect the pipe for any smoke at all the seams & joints during startup.

The high low knob regulates the distribution blower. The only problem that I have noticed with it is..... If you leave it on high it sure blows out the heat but it is short lived.... As the air blows across the heat exchanger heat is removed from it.... If you remove it fast enough the air that comes out the other end will be cooler than you want...
Just a suggestion put it between low and high (med) and the air will blow out at a more consistant rate and also ramp up and down based on the room temp.

I think you are talking about a different knob. He is talking about one that is NOT on the panel door. Its also one I never new about since my unit is a corner install and its hard to see. Plus I do not see any mention of this in my owners manual. Mine is toggle "uP" and I am having a difficult time seeing if that is hgh or low.

no idea........ the only toggle that I have is for ignition (auto or manual)
I'm sure HB will chime in about this for you guys.

I switched mine down to low and I think it is quieter...but I am still getting used to what it sounds like. The only sound I have that I don't like is a real low rumble...but I think that has to do maybe with my hearth or the leveling feet...I have read it should be 100% sitting on the rubber pads...but that seems crazy to me...and again the manual is no help.

The "toggle" hi/low is only on 2 Harman models, the Accentra & XXV. It is located inside the control door on the stove body. It will drop the voltage to the distribution blower on the low setting.

Pros and cons? It is not mentioned in my XXV manual...I plan on calling the dealer and asking him about it. Mine was delivered set to "HI" and I am using it in "lo
right now in hopes of making it run quieter.

I have a Harman Accentra. My only toggle swith is for "auto" or "manual" ignition. This works well in the stove temp mode. It allows you to view a large fire without blowing extra heat into the room. However, when the stove reaches 350f or 81% output the distribution blower automatically comes on.

I know everybody likes pictures, I tried to attach one but my file was too large, I will resend on my next post.

Its a rocker switch...not a toggle switch, and it is not on the swing out door...it is on the stove.

"Its a rocker switch...not a toggle switch, and it is not on the swing out door...it is on the stove."
"It is located inside the control door on the stove body. It will drop the voltage to the distribution blower on the low setting. "

Thats right it is a rocker switch that drops the voltage. I got some info from my dealer.
I included a picture this time.

Thanks for the replies.

What a great tip! I have heard many people talk about the slight smoke smell. This tip tells you how to find it. The dark room and flashlight found the leak. Smoke is coming in from the seam of my elbow "90" and the joint right behind the elbow. The XXV was airtight no smoke leaks. I want to patch this myself instead of waiting for the dealer. What do I use, high temp silicon, brand name, available at Lowes or Home Depot?

Thanks again, this smoke smell will be gone today.

Picture included, the red X marks the spot.

HarryBack · Oct 20, 2006

use RTV silicone, or metal tape, or silicone tape. No need to mention the hi-low rocker, as you guys all did a bang-up job with that....bit it is in my manuals.

I need to call all the experts here:
Is this a good setup?
An elbow facing down?

HarryBack · Oct 20, 2006

Joe...how is the elbow facing down? Maybe im looking at the picture wrong....definitely minimalistic pipe, but it goes from the tee to the 90 and out....kosher.

If the smokey smell goes away after a couple of hours, then it's just the machine oil - some machine oil stays behind on the metal after manufacturing, and comes off / burns when the stove is first fired up.

open a window & all will be fine.

if smoke persists when you're on your third bag of pellets, you have a problem - see the advice above

I already had the machine oil experience. It set off all of my smoke detectors. It was a great test for my smoke detectors!
I opened a couple of windows and all was fine.

I am on my second bag of pellets. This is wood smoke coming through one seam and one joint. I can see the smoke leak with the flashlight trick on startup.

You are right.

The stove is on the right side of the picture. When I looked at it the first time I thought it was on the left side.

buildafire · Oct 20, 2006

The stoves on the right? If it is, the pipe's facing the wrong way. How did the cap get put on..? (I know, I know.. metal tape, silicone, and zip screws. Same as always..)

Hammerjoe · Oct 20, 2006

Oh geez, this is not my day at all.

I wanted to say that the stove is on the left side obviously...
Please dont mind me today.

buildafire · Oct 20, 2006

No biggy Joe, I had to look at both my hands, unscrew a jar, try to remember what side I drive on, and ask my wife before I responded to your first post.. It's Friday. All is forgiven. :smirk:

GVA · Oct 20, 2006

Now you guys have me confused I thought the stove was on the left because of the tapered edges, but what is on the right?
SoCal set us straight which way is it in the picture.

SoCal65 · Oct 21, 2006

Here is the answer to the riddle.

I am still wrestling with the smoke smell. I thought I had it solved.

GVA · Oct 21, 2006

Ahhhhh switching the photo angle around now are we :lol:

HarryBack · Oct 21, 2006

u sure that smoke might not be coming out of that block-off plate from the hearth? Im sure you didnt just stuff the pipe up thru the damper and leave it, right? the damper is AT LEAST blocked off?
