Values are as measured per test method, except for the recommended heating area, firebox volume, maximum burn time, and maximum heat output.
Recommended heating area and maximum burn time may vary subject to location in the home, chimney draft, heat loss factors, climate, fuel type, and other variables. The recommended heated area for a given appliance is defined by the manufacturer as its capacity to maintain a minimum acceptable temperature in the designated area in case of a power failure.
The maximum heat output (dry cordwood) is based on a loading density varying between 15 lb/ft³ and 20 lb/ft³ and reloading intervals ranging from 60 to 120 minutes. Other performances are based on a fuel load prescribed by the standard without any reloading between start and finish. The specified loading density varies between 7 lb/ft³ and 12 lb/ft³. The moisture content is between 19% and 25%.
As measured per CSA B415.1-10 stack loss method.
- Higher Heating Value of the fuel.
- Lower Heating Value of the fuel.
Performances are based on a fuel load prescribed by the standard at 7 lb/ft³ and with a moisture content between 19% and 25%.
Optimum overall efficiency at a specific burn rate (LHV).
The optimum heat transfer efficiency is for the low burn rate (using HHV) and represents the appliance’s ability to convert the energy contained in the wood logs into energy transferred to the room in the form of heat and does not take into account the chemical losses during combustion.

the main gain is my boss is happy. I have been planning for three months with my circle and they suggest this one. It took month to arrive but it was safe after all, my boss was happy. thats it. thank you belleflame.
I bought a few items for my outdoor kitchen, including access doors, drawers, power burner and a grill cover. Belle was having a sale, had no tax and free shipping, make them the best online price I could find. Moreover, after placing my order, I wanted to make a couple of changes to my order - add another item, and change an item. Their online chat help was exceptionally responsive and helpful.
Everything arrived well packaged. Will definitely order from them again.
Belle Flame not only had the best price for the unit I wanted, they also sell many of the parts and upgrades. When my unit was delivered, there were 2 issues in shipping and they stepped up and immediately handled them to my satisfaction after getting details, photos and working with carrier. I would recommend working with them and the Osburn stove is beautiful and excited to get it installed.
Price was way better than anywhere i looked, i was a little nervous about it but everything i ordered came fast and perfectly packaged. There was a slight miscommunication with the delivery company but that was on them not the fireplace store. Overall highest recommendations to use them. Thank you.
Great communication during shipping process, item arrived damage free, was well packaged to prevent damage. Could not be more pleased!
I was looking at the Montlake 300 wood insert on the internet and found Belle Flame. The price were less around $200-$300 from other stores and also they had a sales ongoing. I find this to be a better deal and talked someone named Moni on the phone. He confirmed everything was in stock and will be shipped next day after my order. I was really interested and put the order #4483 with them. We received the insets perfectly on time and make it installed within 3 weeks of purchasing. This is my best purchase ever and I will come back again to belle flame for their outstanding customer service. Thank you very much.

Great company! Very helpful in explaining the Stove before purchasing and the extra features. I ordered it way ahead of the scheduled project and did not install in until 7 months later. Customer services is definitely earned a 5 Star in my book! Many thanks to all there! We'll be calling again soon for our next project.
Excellent, sturdy, good looking product. Property packed for shipment. Arrived undamaged. Convenient scheduling of freight delivery to my home.
Knowledgeable staff, returned phone calls when requested, worked hard to find the correct stove for my needs and applied discount. Just amazing service. It's nice working with a company that really cares.

Order shipped quickly. Good price
The Monesson Linear Ventless Fireplace was shipped as expected. However, one item, had some damage in shipment. I contacted Lionel to let him know. He was very kind and understanding and said that I should send photos of the issue. About a week later a new shipment was received. Unfortunately, another piece was faulty; the fragility of the "driftwood" was hard to keep safe. I contacted Lionel again he requested another shipment, this time with a placard identifying it was fragile. Fortunately the third try was successful. Thanks to Lionel for his great customer service our fireplace is now complete.
Very pleased with the Buck stove that we ordered. Unit was in excellent condition upon receipt. Unit works perfectily and will be added comfort during the long winter nights.
Belle Flame not only had the best price for the unit I wanted, they also sell many of the parts and upgrades. When my unit was delivered, There were 1 issue in shipping and they stepped up and immediately handled it to my satisfaction. After getting details, photos and working with carrier.

Belle Flame worked tirelessly to ensure that my complete order was fulfilled. One of the driftwood pieces was broken in shipment and it took 3 tries to get the job done.
