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

My fire place elecric starter won't work after running out of propane


Most likely, you need to "bleed the line". The new propane needs to travel to your fireplace, but you have a huge air pocket in there now since it ran dry. It takes forever for the air to "bleed" out through the tiny orifice of a pilot light, especially if the distance from the fireplace to the tank is far.

Spuddering in the heat


Your engine is vapor locking.Somewhere in the fuel system the fuel is boiling causing vapor lock.Look at the fuel line where it is closest to a heat source like the intake manifold or exhuast system somewhere.You will need to insulate the line where ever it is close to or touching a heat source.

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.

Gas line had to be disconnected to house last week for a gas leak repair. Everything is fixed and gas is back. Now gas dryer will not heat up. It runs fine, just no heat. Is there something I have to...


most gas dryers have what is called a ignitor on them that will glow when the unit is turned on and after they get red hot then a milivolt signal is sent back to the gas valve to open and fire up... i would check to see if the ignitor is glowing first... you will have to gain access to the bottom of unit in order to see this. you will have to remove front of dryer and most likely the tub,some of the newer maytags have a bracket that will hold the tub in place while working on it... before i did al this though it is possible there is still air in the line and will require bleeding the line at dryer... alot of people are afraid of gas but if common sense used you will be fine... you should have a gas stop at dryer gas supply line if not you need to install one. either way take a wrench and remove gas line at one of the closest connections to dryer and on purpose bleed a small amount of gas out.this will do 2 things (1) it will bleed any air in line going toward dryer and (2) confirm you still have gas pressure and gas going to dryer after your disconnection last week nothing happened to line.then reconnect and try again. if you ran dryer for an extended time it would eventually bleed the line also. not sure how long you ran it,but this will prove you still have gas at dryer . if after that no cure check the ignitor on unit to see if it is working if it is and no flame the gas regulator may be faulty after the disconnection last week/.... good luck to you

    Homelite trimmer, gas, string - y is the string wrapping itself around the head of the trimmer?


    The line on my new 26cc Homelite would also feed out by itself. That started me thinking the line was wound backwards. I wrapped the line in the opposite direction as was shown on the bump feed reel and now the dang thing works although the bump feed needs to be "bumped" pretty hard to work. Is it possible that the reel was manufactured with the (string direction) arrows pointing the wrong direction? The new 26cc unit is also underpowered compared to my older 25cc trimmer.

    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.

    Install HE220 HoneyWell , humidity not increasing in the house.


    You can try installing the water line to your hot water if it is installed on cold line for more humidification. You should make sure your humidistat is up line 6" @least from humidifier for proper humidification measurement.
