An insert has one job an open masonry fireplace cannot do: keep the heat in the room. Your existing fireplace pulls warm household air up the flue and sends most of the fire's output with it. A sealed insert with a dedicated liner reverses that, and the Matrix 2700 does it while producing just 1.2 g/h of particulate — the lowest figure across the Osburn insert range.
It also has the widest door in the line at 25⅝", which matters more than the spec sheet implies. A wide, low viewing area reads as a fireplace; a small square porthole reads as an appliance. The Matrix 2700 is the one that still looks like a fire once it is in the wall.
Low particulate output is not only an emissions statistic. Unburned particulate is what condenses in your liner as creosote, and creosote is what feeds chimney fires. A unit burning at 1.2 g/h deposits substantially less than an older stove running at 4 or 5. You will notice it in your annual service.
Non-catalytic combustion, so there is no combustor to degrade and replace every few seasons.
This is the part people underestimate when pricing an insert. A wood insert must be connected to a continuous stainless liner running the full height of the chimney — listed to ULC-S635, CAN/ULC-S640 or UL1777 — with a minimum of 15 ft of chimney height for adequate draft.
You cannot vent an insert into an unlined masonry flue. Budget the liner, the insulation and the labour alongside the appliance; it is a meaningful share of the total, and we would rather you hear that now than at install.
Send us the width, height and depth of your existing fireplace opening and we will confirm the Matrix 2700 fits before you order — and quote the liner in the same breath. (540) 212-9374

Q: Why is the efficiency as per the EPA’s test data smaller than the publicized optimum efficiency?
A: EPA refers to the CSAB415.1-10 standard for the calculation of the appliance’s efficiency. The efficiency reported as per EPA’s directives consists of an average between four different burn rates, ranging from the lowest burn rate (air intake completely closed) to the highest burn rate (air intake completely open). The optimum efficiency that we publicize is the efficiency obtained according to the same test data, but for the low burn rate only. This efficiency is more realistic for a majority of users whose heating needs require that the unit be used to maximize burn times.
Q: Why is the BTU according to EPA test data smaller than the one advertised?
A: You will notice a difference between the BTU output as per the EPA’s test data and what is advertised on our web site and/or product literature. The maximum BTU output we advertise is what will be obtained with a full load of seasoned cordwood inserted inside the firebox. The EPA output, on the other hand, is what has been obtained during emissions testing. The EPA test procedure requires that a special type of wood is used and positioned inside the firebox in a manner that does not represent the way the firebox volume would normally be utilized using seasoned cordwood. The EPA test load is typically much smaller. Hence, the BTU as per the EPA’s test data is reduced. The BTU output that should be considered by a normal user is the one we advertise for seasoned cordwood.
Q: Will my insert work in the case of a power failure?
A: Your insert can be used in a power failure. An insert is built like a wood stove. The only thing that will not work in a power failure is the blower. Operating your insert without the blower will not damage the unit. The disadvantage is that you will not benefit from the heat circulation around the insert’s jacket. Inserts come with a blower because a large portion of the unit is inserted into a masonry opening. The heat that radiates from the portion of the firebox inserted into the masonry hearth does not reach the room as it would with a freestanding wood stove. This is why inserts have a jacket built around the back portion of their firebox. The heat is trapped inside that jacket and is pushed back in front of the stove and into the room with a blower. Without electricity, you will not recover as much heat from the unit. The radiating heat will come mainly from the glass and the front portion of the insert.
Q: Why does my wood insert blower not move a lot of air?
A: All of our inserts and blowers are designed to complement each other. It is a matter of achieving the greatest amount of heat transfer from the unit. The key is to design the insert so air can move and extract the greatest amount of heat without cooling the firebox and hindering the efficiency of the unit. If the blower velocity were to be increased, it would give the impression that the unit heats more. However, it would actually blow cooler air and reduce the unit's efficiency. A hot firebox will burn better and cleaner. A slower but hotter air displacement is therefore always preferable. The same principle applies to the heat sensor available on many models. It is better for the heat sensor to activate the blower later, when the unit is very hot, rather than activating it too early and blow cooler air when the unit is still completing its start-up phase.
Q: Can I install a liner with a 5-inch or 5.5-inch diameter?
A: All of our inserts are designed to function with a 6" liner. However, it is adequate to install a 5" or 5.5" liner when the masonry chimney is too tight for a 6" liner. Under certain conditions, the probability of a drafting issue is increased, which could favor smoke spillage and/or reduce combustion quality. But generally speaking, the vast majority of homeowners who properly install a 5" or 5.5" liner and use good heating techniques will be very satisfied with the performance of their wood insert.
