Rudd exhuast and air intake lines

When gas heat unit installed the installer ran exhuast line out underneath a gas fireplace bump out pointing toward the ground. the air intake line comes out within 10" also pointing down. both where varied lengths. i cut them off at the same height. but it seems like while the exhaust is venting the intake line is taking the same air in. should something be changed ?

    Where the lines come out it is about 6 feet off the ground. The basement is exposed. this unit was installed about 10 years ago. does it make any differance now? i could cut the exhaust line and bring it out straight thru the rim board of the fireplace bump out and and the put the gooseneck on? this would put the exhaust port 2 foot away from intake.

You need to make sureyou are at least 12" above ground with your termination if you live where you get accumulating snow levels. Next, your exhaust needs to be separated from your intake via a "goose neck"(straight pipe out of your house with 90 degree elbow pointed up then attach a 10" piece of pipe with a 90 degree elbow pointed out away from your house. The reason you want to keep them separated is that your intake will **** exhausted air into combustion chamber causing burner lift etc. due to no oxygen to properly burn. I usually put a 45 degree on intake so it is not so inviting to birds etc. Good Luck

Blade on fireplace heat o lator appears to be turning the wrong way. Heat does not come out of the top of the fireplace. What do I do to be able to take out the heat o later and reverse the fan?


Roger. it depends of whether this is a Gas Fireplace or a Wood Burning Fireplace?

If it's a direct vent gas fireplace, the blower was installed incorrectly. To access the blower, you will have to dismantle most of the interior of the firebox and the burner tray (Interior floor of the firebox). This will involve disconnecting the gas line from the burner. The blower is on the floor of the control compartment and is attached to the rear wall of the control compartment. Whoever installed it, has it aimed in the wrong direction. Which is can of hard to do, since there is an arrow on it, pointing in the UP direction. Once you unplug it, you can take out the sheet metal screws that hold it in place, and it will be quite obvious which way the exhaust should face. Which is UP.

Now that I've told you how to do all of that, I must be totally honest, by telling you, the blower will not increase it's efficiency. Your Direct Vent Gas Fireplace is rated as a Decorative Gas Appliance only. It is not heater rated. In fact, 80 % of all the heat goes out the direct vent. The only real heat, is generated off the glass, once it's hot.

So now, you get the chance to make the decision. With all that's involved, is worth changing the blower and not really gain anything?

If you have a wood burning, brick fireplace Heat-a-Lator, just turning the fan motor around, so that it's pulling air into the chamber, will solve the problem.

I really hope all of this has helped you. If I can be of further assistance please let me know. Thanks.

We have not turned the heater on since 2010. it is a gas with fake logs.A rennai flame fire inbuilt standards. Husband says the thermacouple is not working? what do you recommend?


Stephanie, I 'm not sure how it was determined, that your direct-vent gas fireplace needs a Thermocouple? As a dirty pilot light will also mimic a faulty thermocouple. In addition, if the fire hasn't been used since Winter of last tear, and the gas line to the unit has been turned OFF since then, the air in the gas line must be purge, before the Pilot will light and hold.

If all of the above can safely be ruled out, then the thermocouple should be replaced. The facing of the fireplace will have to be removed, to access the Thermocouple.and it's connections to the gas control valve. You didn't mention which Rinnai Gas Fireplace you have, but most if their units, use Thermocouple part # 90193475. If you're going to replace it, it would be a good idea to also replace the Thermocouple Retainer, part # 9377.

I hope this helps you to further troubleshoot and solve the problem. Please let me know. Thanks.

I have a valve on the wall with a Hearthmaster key. In the fireplace is a long tube with slits cut every 5". Is this a gas fireplace or what?


From what you described, it sounds like a homemade gas log lighter for a masonry, wood burning fireplace. The Key in the wall is to turn the gas on and off. With that said, no it's not a gas fireplace per se. It's used to light firewood. However, if you don't want to burn wood (with all the fuss, muss & dust. You may be able to install a 99.9% efficient, Vent-free Gas Log Set, by using the existing gas line.

However, it's not a case of one size fits all. You will need to know the following concerning the interior of your firebox: Width, Height, Depth (from the center of the opening to the rear wall of the firebox, on the floor of the firebox) and the Width at the back. And the final dimension (if you have a wood mantle) The distance from the top of the opening of the firebox to the bottom of the mantle shelf. If it's less than 18", Code requires a heat deflector hood to be installed to the top of the opening of the firebox, to direct the heat down and away from the mantle.

Generally speaking, I do not recommend this as a DIY project, If you decide to pursue this, contact a professional in your area that sells and installs Vent-free Gas Log Sets. That way, you'll be able to determine which BTU Output is suitable for your application. They're usually in the Yellow Pages under Fireplaces.

Two pieces of advice:

1. When it comes to BTU Output more is not better. Gas is a warm moist heat, that you'll feel very quickly and it's very comfortable. You actually can do more with less.

2. Avoid Ceramic Fiber Logs. They are very fragile and do not hold heat and radiate it back into the room. Stick with Refractory Concrete Logs. They are heavy and very durable. They get hot hold heat and radiate back into to the room, even after the burner is turned off.

Everything I have told you is based on by 15 years in the hearth business.

Amcoraire minisplit A/C Model #AOS121HX Not cooling/heating P4 and p8 error codes After having the A/C head unit previously installed. I had to remodel and relocate the head unit to another...


P4 is a overheating compressor code in the outdoor unit. You probably still have a leak. Have your brother remove the remaining freon and pressure/leak test with a charge of nitrogen. I'f its leaking out this fast you should be able to find the leak with a soap solution. Once you've found the leak, pull a vacuum and flush with nitrogen before recharging the unit.

Can you tell me where the drain valve is located so I can flush out the pipe. The Rudd unit is UAKA060. thank you


The only standard location of the drain line is at the point of origination.....which is the Air Handling Unit. Air Handling Units are typically installed in the Garage, Under the House, in a Closet, or in the Attic. You will have to locate the drain at the Air Handler and follow it to the end. Typically, the end of the drain will be somewhere near your condensing unit. In time, they can get broken off or buried which could make them very difficult to locate. In rare instances, I have seen them terminate into a sewage vent line (NOT recommended and against code in most places). They could terminate just about anywhere; hence, why the best thing to do is to find it at the air handler and follow it to where it leaves your house.

Without being on-site, toolbox in hand, I hope you find this helpful. :-)

Rudd 2.5 combo ac/heat unit


This could be due to a freon leak or the condenser unit needs cleaning also the evaporator in the attic should also be cleaned and inspected. If cold sweat is not seen outside on the large line going into the outside unit I believe you may have a freon leak. Sea Breeze

I recently bought a 4 ton 14.5 SEER Rudd Spilt system using R-410 and matching Rudd furnace. This system replaced a Lennox 10 SEER 4 ton unit. Now that it has gotten hot in Baton Rouge LA 90-93 degrees....


Sounds like the Unit might be low on charge.But without correct readings not sure.
The new unit with 410 will actually cool better due to higher boiling point temp. of freon type.Poor air circulation could also cause problem.Such as dirty filter, too slow fan speed,dirty coil.Also could have obstruction in freon lines either at pump,in line set,or in coil.
Get someone u trust to check it out and ask for their Rudd Dealership Training Credentials.
