It is against EPA regulations to use recovered refrigerant in any system other than the one it came from without it being recycled by a liscened recycler. If any water vapor had been into the system or if a compressed had burnout it could quickly destroy another system. There would be no way for...

Some gas valves open slowly and others just open. Often times the valves that are a slow open do not open as fast as the did when new, which causes some of the symptoms you describe, like the rumbling puff. This could also be caused by dirty burners that need to be cleaned and the air adjusted.

On the circuit board of most newer furnaces is a3 amp automotive style blade fuse. It would have blown this fuse. They are tricky to find sometimes but it is on there.

I wish I would have seen this quicker. It was quite common for Payne and Bryant 383KAV and MAV models. The igniter tries to light but small cracks keep it from doing so. It's almost as if thermal expansion helps to close up the cracks. There is a nitride igniter available that is much more...

What Bill is saying is that b-vent is not a category III vent material, it is category I.

It's a little more complicated than that. For instance, you could have two rooms that are equal square foot but if one has more load walls then it's going to need more air. Direction also plays a critical role. A north facing room is going to need more heat than a south and vice versa for cooling.

I installed sme reclaimed black walnut above my my fireplace and wanted something with a uv protector that was a clear matte finish. It proved to be more difficult than one would think. I ended up with a product from Sikkens called Cetrol that worked great to seal and protect.

Schedule 30 is typically used on all new houses in Michigan. It is only used for the 3". As stated before this is because 3" fittings will fit in walls. All underground plumbing is schedule 40 so a bushing is used to adapt. Around here it can be purchased at any of the big box stores but...

I think people see these in their local service garage and think it's the way to go. They are decsigned for a specific application and the typical residential garage is not it. They work great in high ceilings since heat rises, but in a radiant system you are heating objects that are typically...

Every manufacturer has different bonding requirements. What pipe are you intending to use?

The BTU output is going to relatively the same weather it's NG or LP. While you are correct that LP has more BTU per cubic foot, the new spring and orfices are going to compensate for it. I would first set your gas pressure using a manometer. There are many issues that will develop from not...

I would be hesitant to use basic bath fans, they rarely move anywhere near the advertised cfm. Their numbers usually are only achieved when tested without any duct attached to them. You almost need to see the fan curve to make a decision.

I agree with the others that it Should not fire if the pressure switch is not making. It is also imperative to have good ground for the flame sensor to work properly. I have had them work fine for years and then all of a sudden decide not to. Also pay close attention to the igniter. A small...

Be careful, older ones were often made using asbestos.

In my twenty years brown is the standard jacket color. White is also available and is usually plenum rated, which costs slightly more.
