Hi All Need some help with a new Enviro Meridian Pellet stove been burning for 2 weeks today except for 3 days last week when we were down to -20C (-4f), stove never threw enough heat had to use furnace. It seems to be burning dirty and not throwing much heat. Running on 3, 4 or 5 need to clean the stove every day, burn pot fills up to overflow, on setting 2 it can go 36 hours. It does heat enough around 0C (32F) but gets a whole lot colder then that here in Eastern Ontario. Have tried 2 different pellets Canadian Tire CanWick 12 bags and now Cubex hardwood. Stove was self installed, has 3 inch venting. Not new to pellet stoves have an old EF V Evolution that broke down 2 years ago, bought that new 2007, was floor model, using same venting for new stove. It heated great but tried the propane furnace for 2 years, can't afford that it would be almost $400.00 a month 12 equal payments, old stone house. So we decided to buy new Pellet stove, liked Enviro but wanted bigger stove, more reliable and maybe save up and fix old one for basement, so went with the 45,00btu one. The old stove heat output sure beat this new one seeing old one was only rated at 30,000. It is currently tore apart in basement, that will be another thread one of these days. So far have set pellet feed rate down and combustion rate up, made no difference. Using same venting as old stove, venting was all cleaned before new stove install. Called dealer they blame the pellets, said could do a service call but we don't have $200.00 for a service call, out of work at the moment. Salesman asked what he would like them to do for me, not really sure except some hints what might try. I can't see a service call doing any good anyways. Have enough experience with a pellet stove to know what the flame should look like. Tried 2 different pellets, brother inlaw and nephew both burning Cubex with good results and they both using a big box store stove. Looking like i should have went cheap instead of spending the extra on an Enviro. Dealer doesn't think venting would be an issue, stove is rated for 3 inch pipe. Have the clean out T at the bottom, then 4 feet up then 90 out 3 feet at slight angle up, worked fine with old stove. Sorry for the long post, trying to get all the information there that might be needed. Any ideas to try would be appreciated, just at one of them points life where can't really afford the hit of problems with a new stove if the stove is the problem. Will try to attach a pic of the burn pot at 24 hours at setting 3, 4 and 5 look the same just a hair worse as settings go up. The date on pictures will be wrong, never set that. Enviro Meridian, new in crate, Build date June 2017.
