So the question is then does the sap/resin in itself cause creosote to form by burning it? Kevin

No, just the opposite. All wood releases volitale organics when it burns, and these guys condense as creosote as soon as they find a surface cooler than 250°. Pine resin burns hot.

If someone is burning 60% MC pine, they will have a hotter fire, and therefore less creosote, than the same stove burning 60% MC oak.

You know how people here are always telling you to line and insulate your flue? Flue temperatures are important for a couple reasons, and creosote accumulation is one.
 
I've never had more creosote with pine than with hardwood. But the key to all wood is that it is properly seasoned. The stove can't tell the difference between hardwood and pine.

All I burn is pine here in northern BC there is tons of standing dead pine after the pine Beatle kill. Mc is below 10% cut it and burn it. Take only the standing, the crap on the ground gets punky and smoulders

Seasoned wood burnt in a hot fire should work out well. If the pine were cut 3 months ago, or you threw in big pine logs into a slow fire, that would be problematic. In our stove, if there's no smoke coming out of the chimney (there usually is zero, not even odor), the creosote accumulation is very small.

I have a Garn 1500 heating my 1,500 sq' house.

Would it be safe to go with 25% pine in my fires?

Thanks

like ive said several times in here, there are many places in the world where the only trees available to burn are pine. these people dont import oak or drive hundreds of miles to get some burnable maple. Burn the pine :p

The sap/resin is a fuel. If you season the pine, you'll season the moisture out of the resin too. It will burn just like the wood.

From what I've read about Garns and the more or less infrequent short burns, I'd be burning eastern white pine that burns hot and fast and selling hardwood for the $$$$.
I burn quite a bit of pine because I unfortunately have a lot of it. My only complaint is how fast it burns and isn't much good for an overnight fire. It does burn hot though. It's great for the first fire in the morning to get things cooking again.

Yep billb3 my Garn is a 1,400 gallon tank of water with 25+' of flue running through the tank. The flue gasses cool off before leaving the water tank. With a 17 sq' fire box I load in around 100lbs of wood about every 24 hours.

I ended up cleaning the internal flue after the the blower started making noise. I did a full clean out of the flu and mostly found ash like all my other clean outs.

The only pine on my property was from wind breaks I planted to protect the other trees I have planted.
