Frequently asked questions

We are interested in putting a gas stove in our existing house. I have heard the terms B-Vent and Direct Vent. What is the difference?
B-Vents take air from the room and house for combustion and send the final products of combustion up a single flue, usually of a 4" size. B-Vent, in all cases, has to run up the full height of the home like a stove or furnace chimney. Direct Vent models offer the greatest efficiency of all vented appliances, and the most versatility in installation due to the option of horizontal or vertical venting. Vent pipe may terminate through a wall or through the roof. A double wall vent pipe is used; one chamber provides outdoor air for combustion while the other provides a passageway to exhaust the fumes; this system balances incoming combustion air with outgoing exhaust air for a "balanced" operation. Direct vent does not remove heated room air to provide combustion for the fire. Their performance is not generally affected by home construction issues and they usually work perfectly in all installations.    
I am interested in buying a pellet stove. Is there any benefit to getting one with automatic ignition?
In my opinion, yes. With a pellet stove that does not have an automatic ignition system, the user is required to use a "gel" and a match or lighter to start the unit. And every time that the unit goes off it has to be restarted this way. There are two reasons that this in inconvenient. One is that pellet stoves usually require electricity to run. If the electricity goes off, the user has to restart the unit. The other reason is that if the unit runs out of pel-lets, again, you have to restart the unit after refilling. This should not be the case with an automatic ignition stove. First of all, they do not require a "gel" or match to light and they will restart themselves. The pellet stoves that I am most familiar with are made by HARMAN. They have some fully automatic stoves that offer two operating modes. In Stove Temperature Mode, you select a burn rate and the stove will remain at the same burn rate regardless of the room temperature. In Room Temperature Mode, the stove constantly monitors the temperature in the room and adjusts the size of the fire and the heat output of the stove so that the room is kept at a constant temperature. Controlling the burn rate makes the unit more efficient.
Ok, I give up... What's Spider?
It is Johns Manville's Formaldehyde-free Spray-in custom Fiber Glass Insulation Delivery System. It offers a revolutionary way to insulate homes. Spider is engineered for superior thermal and acoustical performance, as well as fast installation, complete coverage, quick drying time and mold resistance. Spider is lightweight fiberglass insulation bound together with a non-toxic, water-soluble adhesive that also binds to cavity surfaces for gap-free coverage. Spider sprays in to fill an 8-ft. 2x4 cavity in about 20 seconds. Because Spider is made without formaldehyde, it improves indoor air quality and promotes a healthier indoor environment. This is important because the World Health Organization's International Agency for Research on Cancer classifies formaldehyde as a carcinogen. The Environmental Protection Agency (EPA) recommends limiting exposure to formaldehyde as much as possible. JM offers a complete line of formaldehyde free fiberglass insulation.
