Q: I have an old house and for whatever reason, there is not a damper at all (never was) on the fireplace. I love vent-free logs and am planning on installing them in this fireplace. Do you make a product that I can use in lieu of having to have a damper installed in order to keep the heat from my vent free logs in the house? _ ET
A: ET, I’m sorry we do not have a heat-resistant version of the Chimney Balloon. Our product is actually designed to release if exposed to acute heat. I wish I could direct you to this issue, but your fireplace and mantel may not be well equipped to handle the heat spillage from a vent-less gas log. I wouldn’t want you to risk a fire from having heat spilling up across your lintel and mantel. You may want to think carefully if this is in fact how you would like to heat that room. – Jason

Q: Jason, We have a coal-burning fireplace that we will never use. The chimney has a smoke shelf and (as far as I can tell) no damper. The chimney measures 14 X 16 just above the smoke shelf. I guess that means we will need to order a custom Chimney Balloon. How much would that cost and how do we go about doing it? – ST
A: ST, Just to be on the safe side I would go with a 15”X18” custom Chimney Balloon.
FYI, If your smoke shelf is far up your chimney you can also measure the space below the smoke shelf and before the damper if that allows enough space for the Chimney Balloon. The most important thing is to look for the most convenient space to reach. If the best location is higher than 12 inches past where you can touch with your hand, consider purchasing an HEK Extender with your Chimney Balloon. – Jason

Where to Measure a Heatelator Pre-Fab Fireplace
Q: We have a 2 sided fireplace on the ground floor of our house and a 3 sided fireplace in the basement. Our house was insulated from electric heat. When we have a fire in one fireplace we get smoke coming back into the house through the other one. Would a chimney pillow stop the smoke from coming back in? Thanks very much for you help.- JU
A: Dear JU, Correct me if I am wrong, but it sounds like you have two separate chimneys for your two fireplaces they just share the same chimney structure? (like in the picture on the left)
If the answer is Yes, you do have two separate fireplaces and the flues are separate. Then the Chimney Balloon will stop the smoke from crossing over and re-entering the house through the other chimney. – Jason

A: Dear JJ, Correct me if I am wrong, but it sounds like you have two separate chimneys for your two fireplaces and the two chimney flues go up one main brick chimney structure?
If the answer is Yes, you do have two separate fireplaces. Then the Chimney Balloon will stop the smoke from crossing over and re-entering the house through the other chimney flue. This is called smoke crossover. It is when the one chimney is breathing out air from the home and smoke from the fire mixed together, the other chimney is breathing in outside air to equalize the pressure in the home but is also sucking back in smoke.
Many people assume closing the damper on the unused fireplace will stop this crossover, but that is not the case. Dampers are not tight enough to stop this air draw. That is why a Chimney Balloon is needed in the unused fireplace to stop the air draw inward through the second flue. This forces the house to find another location to draw air in at where there is no smoke.

Q: I have a set of gas logs that are un-vented. Am I able to use the Chimney Balloon to completely seal off the outside air and use the fireplace at the same time? I have a damper and would keep it closed, but I would be afraid the “auto-deflate” option might kick in on me. – NE
A: Dear NE,
Even if it is a vent free gas log If you light a fire under a Chimney Balloon it will burst and deflate. The heat will sneak up past your damper and get the Chimney Balloon to its burst temperature point.
However, it does benefit you to have the Chimney Balloon in while the vent-free gas log unit is not in operation. – Jason

Q: Jason, Should I be concerned about using the Chimney Balloon to plug the flue if I have a gas fireplace and the pilot light is continuously on? The fireplace also has glass doors that seal about 90% of the fireplace. – CT
A: CT, A small pilot light will not burst the Chimney Balloon, but do keep in mind that when you seal your flue you are essentially eliminating the outside air source for your pilot light. So if the flame goes out the fuel smell will go into the house, and likewise all gases created by the pilot light burning are going into the home. It is our opinion that the gas source should be turned off along with the gas to the pilot so you have no backup of any kind into the home due to the energy saving tight seal of the Chimney Balloon. We realize this is an overly cautious statement to make, but our customers safety is foremost to us. – Jason
