Installing Gas Dryer - DIY job?
 
3 Attachment(s)
Just bought a natural gas dryer from Home Depot. It is set to be delivered next week. I am considering doing the install myself. The laundry room is already set up for a gas dryer except that the furnace is on the other side of the room and I am not sure how to vent the combustion gas from the dryer without running duct work across the ceiling.

Best done by a pro that knows what their doing. What if you don't make a connection right or its not vented properly. Best to install co2 detectors around that area too

gas dryer gets vented directly outside with flex duct:wink: not to a flue of a boiler furnace.is that a elbow to outside vent hood over the window....get a flex connector and brass adapter for the gas drop connection to the dryer and your done.take the black nipple and cap off the bottom and go in with the brass adapter 3/4MPT X 3/4 flared that takes the flex gas line.dryer package should have a brass fitting to land the flex gas line...into the dryer

Some locations, however simple the work may seem to be, prohibit non-licensed people from working on gas piping. You might check on that.

I agree with biggles; easy job. Just spray the connections down with soapy water to make sure they don't leak. Big box stores sell the connection kit for this.

So ALL exhaust (combustion and dryer air) is funneled out through the flex vent ducting? I thought the combustion air was supposed to be separate?

Combustion and dryer exhaust go out ONE pipe.

Look at the install directions for the dryer. It should tell you how to hook the exhaust up.

NOTE: there are limits as to how long the exhaust can be. It should be in the install directions too.

he mentioned the furnace on the other side of the basement....the vent flex from a dryer is the exiting pipe and only one...:censored: do not go near the furnace hard ducted flue piping for the furnace and HWH...:wink: he is adding a brass adapter not piping the Alaskian Pipeline....simple piping job it isn't brain surgery.OR get a plumber in to bang you for a couple of $100 bills

I can't disagree with you. However, that doesn't change the fact that it is illegal in some places for a non-licensed person to do gas work. Such a situation is also common for even the simplest electrical work as well.

It is legal here for me to do my own gas piping, but using soap bubbles won't cut it; a 24-hour air-pressure test is required. How many homeowners are going to have the equipment for that?

yeah, there really isn't much to it.

Yep....in those states where the unions own the govt....

Anyway...getting back on topic....

There is already a gas line dropped to where the back of the dryer would be. Add a Tee...on the side connection a shut off valve which the flexible gas line for the dryer will connect to...on the down side...about 4 more inches of pipe with a cap to act as a drip leg.

Assuming that exhaust duct goes straight outside....4' hard duct up to it from the dryer....and you have an operational dryer....

A licensed pipe fitter is not going to do a 24 hour leak test for a job like this.

If the job's in my county he will.

Eagle One 09-12-2013 10:54 AM

Ok, let me clear the air on the legal requirements. I contacted my county permit/inspection office and they confirmed that a licensed installer is NOT required for this work. However, you do need a permit for the work. After several return calls to the permit office (received conflicting information), I discovered that the permit cost is $50 and will include an inspection.

I like the idea of having a shut off valve there too in case the dryer needs future work or has to be moved. I also have heard about using the rigid metal ducts (or a periscope type duct as they call it) versus a metal flex duct. The rigid metal duct allows less air disturbance and can even decrease drying times (one report indicated a savings of ten mins off the dry time). It also seems safer versus the flex duct. However, it seems that I would need maybe 6 feet or more to go from the bottom of the dryer to the vent above the window. I have seen 4 foot ones for sale but not larger ones. Any recommendations on that?
