How wide are the channels? Mortar is ok for smaller areas less than 3/4" any bigger than this I would want to use fine aggregate cement (not just sand as in Mortar).
The fact that one branch duct is at the end doesn't mean much. You could install a damper there to balance flow a bit. Of bigger concern is that they used flex duct and bent it severely. If the one in the photo is any indication, they didn't do a great job. You shouldn't see such sharp, tight bends. It also doesn't appear that flex duct was necessary ...
My furnace would ignite the pilot and energize the induction motor but the main burner valve would not open. At first I suspected a bad coil on the vale selonoid but continuity check indicated it was good. Then traced around with my meter and got to the pressure switch. It was not switching when the induction fan ran. I removed the tube from the furnace and ...
Cut the gas back some by slightly closing the gas valve (the one on the pipe, not in the unit), however be prepared to have to reset the furnace occasionally if your local gas pressure drops intermittently. Watch the flames as you do it. Just, "take the edge off". This will cost you more in electricity, as it'll run longer to come up to temp, but it will ...
Having an oversized furnace compared to the needs of the conditioned space should not cause furnace limit problems unless the duct system is too small. If the furnace was installed by the same people as the duct system they should be allowed to address the problem. There are limits to how many outlets can be closed without causing this problem.
After cleaning the flame sensor, checking ground wire, checking exhaust for cracks or blockage and the board connection. We found that the hanger on the exhaust pipe was hung poorly and causing pipe to droop down which made it hold condensation that ran back into unit which shut the furnace down.
If partially closing a single supply vent caused your high limit to trip you probably have an restriction problem. I would recommend investigating a bypass damper with a return and supply temp. sensor. These devices are typically just a part of a whole house zoning system, but can be used to easily resolve supply air restrictions in situations where ...
My Trane (5 yr old) has different possible blower settings for the heat and non-heat periods. My house was getting chilly in spots. So, I turned the fan up during the periods when the thermostat was not calling for heat. That circulates the air and has made the house a more even temperature. Meanwhile, the blower setting when the furnace is on has been ...
You can't. I have the same problem. My house has a 125,000 BTU furnace for a 25,000 BTU heat load. My solution? I set the thermostat at 69 and turn it on manually when the temperature falls below 65 or so. This ensures that the furnace runs for a nice long time when it's on, and then stays off the rest of the time. But you don't really even need to do this ...
