Crown Royal 7200mp

[Terryl]

I started mine in November , my dump truck loaded is roughly a cord. In 2 months I have burned 7 dump truck loads. I most likely would have burned at best 5 dump truck loads by now with my old Hardy . I have read the manual and did some trouble shooting but, still haven’t figured out the troubles.

I bought this new in October, it was installed by the dealer. Like everyone we are getting older and our thoughts were to get a more efficient boiler so we won’t need to cut as much wood or buy as much wood. So far that thought didn’t work. We had more wood than we ever had before with our old Hardy we installed in 2006. I am wondering could this Crown Royal 7300 mp be a lemon? We are almost out of wood and it is just getting below 30 degrees here in Ohio.

I think I speak for everyone here when I say we feel your frustration and have been there at one point with a product in our own lives. We are here to help and thank you for posting about your issues BUT …..

Unless you give us some more details about how you’re operating the stove we can’t really help any more other than to jump on the bandwagon and say “it’s junk!!” which it likely isn’t. No one here is about to call you stupid or anything like that if you share details we think can be changed about the stoves settings and how you’re loading it and such.

What is your temperature differential ?

What temp does the stove kick on at ?

What temp does the stove kick off at ?

Is your multipass area plugged up or coated with creosote junk ?

How many times and how often do you move the shaker grate lever ?

How do you load the stove ? Wood orientation mostly. Side to side or lengthwise ?

How long does it take to run a burn cycle ?

Is it plumbed correctly in the back ? Mostly are the supply and return lines going into the correct ports.

With these details we can paint a better picture of what you have going on. Hopefully your dealer will ask the same questions and give you some pointers. These stoves operate different than your old Hardy and require a different approach. Sort of like how it’s different driving a car vs an suv in the winter snow. Both will likely get you to your destination but both will do it differently. Believe it or not these MP stoves (from most all brands not just Crown Royal) are the suv and should do a much better job.

load my wood length ways with the fire box. Temp is set at 175, kicks on around 165. Temp goes to 175 and blower kick off. Burning dry seasoned wood, cherry, oak , hard maple, elm and ash. I shake the grates a couple of times when I load it. Multi pass is clean. I clean it out a couple of times a week, empty the ash pan every two or three days. Hope this helps with this information.
My dealer advised me to shut off the fan on my heat exchanger in my garage which I have done. Not burning as much wood, but, I’m not heating as much sq. Ft. Now either.

Try moving your temps. 180* off and on at 170*.
That really seems to be a sweet spot for all boilers.
Not sure if this has been mentioned, check door gaskets. Especially the ashpan door. If it leaks air, you're burning while furnace is idling.

Will do, thanks

Wow! A little off topic, but moral of the story is don't forget which email you have linked to this site. I had to re register with a new user name (woodman1 was my old name) because the site had a 2 step verification that sent a code to an old email I no longer use. Anyway, It is good to be back and hopefully I don't forget which email this is linked to.

Enough of that...I just wanted to throw this thought out there to the OP. A friend of mine has a hardy I think H2. Hardy recommendation at the time was to simply run pex lines in a PVC pipe for underground lines. Also the recommendation was for the circulator to only run during a call for heat. Just wondering if this is how your hardy was setup and if now your circulator is running 24/7. I could see how your wood usage went up if you have poor underground lines and the pump went from demand to constant on.

I run my 7400MP at the same settings Terryl has as well most of the year. When it gets butt cold I’ll bump it up to 170-180 and don’t really notice a change in wood consumption.

Door gaskets leaking is a good thing to check. I’d imagine you have the updated door with a latch on top and bottom unlike mine with only one latch in the center. If your door was leaking you’d know. There would be all kinds of water and goo coming out the bottom of your door and you’d have upside down brown icicles on the ground under the door.

Are the doors to your blower motors closing all the way between burn cycles ? The stove should not really be smoking at all in between burn cycles. If the loading door was leaking or the blower doors were not closing properly it’d be smoking pretty much nonstop.

I get smoke when the blower kicks on, then it dies down. No smoke when blower is not running

Well that’s good. Keep us posted on what the dealer finds. It sounds like you’re doing a lot of things the same way I do other than loading the wood the opposite way. It made a noticeable difference for me but it sure didn’t cut the wood use in half.
