Even after a lot of research, there are a number of frequent questions people have about their new gas fireplace system. We have compiled them here, to save you time and effort. If you have a question not on the list, please write us here, and send in your question.
We service the following areas:
Best way to place order is to call us. But if you are feeling lazy, you can submit the order through the contact page.
To be safe when determining what clearances are required from a TV or other electronic device to a fireplace, you should find out from the manufacturer/distributor of the component, not the fireplace. Clearances to combustibles around and above a fireplace can be well within certified specs but could still possibly be too close for TV’s and other electronics.
A direct vent fireplace has a completely sealed combustion chamber which allows it to vent directly out a side wall or through the ceiling of your home. The benefit of this system is that it brings in air from the outside of the home rather than using the room air.
Harji’s direct vent fireplaces use a co-axial venting system. The co-axial vent system has the exhaust pipe within the air intake pipe which protects any surrounding combustible material from the high temperature of the flue gases as well as preheating the outside air prior to it being introduced to the combustion process.
Vent free fireplaces are fireplaces that do not require any type of vent system. Instead, they are designed to burn clean and the combustion by-products allowed to flow into the room the fireplace is located in. Stringent requirements ensure that these fireplaces not only burn cleanly, but that they are located in rooms of sufficient size to ensure an adequate supply of fresh air is always available for the combustion process. A highly sensitive sensor is employed to turn off the gas to the fireplace should the level of oxygen within the area begin to deplete. The most obvious benefit of this type of system is that no heat is lost through the venting system making the fireplace virtually 100% efficient. Currently, these type of gas fireplaces can only be installed in some areas of the United States. They are not approved for use in Canada.
BTU’s (British Thermal Units) are a standard of measurement which represent the heat value of any type of energy used to create heat. The amount of fuel that a fireplace will consume per hour is calculated with the BTU value of the fuel it uses to determine the input of that fireplace. BTU values of any type of energy are determined by the actual amount of heat required to increase the temperature of one pound of water, by one degree Fahrenheit.
Radiant heat is transmitted from a heat source via rays just like rays of sunlight. These rays pass through the air without heating it since only solid objects can absorb the heat they transmit. Dark colours absorb more radiant heat than lighter colours which reflect more of it. This is why light coloured clothing is cooler than dark coloured clothing. All our Napoleon Fireplaces are designed to generate radiant heat into your living room.
This is the transfer of heat through a body or substance. All of our fireplaces conduct heat to the air as it comes into contact with the hot glass and firebox surface.
