Well Yes but it does so in the form of vapor. Would be easier if I knew computer tricks. Anyway Natural Gas is "CH4" ,for every cubit ft of gas you need ten Cft of air n8o2. This results in:...

I'm still working on my initiation; quality takes time.

Realizing that it is a plumber appliance they probably just let the condensate run down the hot vent and hope it boils off before it gets to the burner, I hate plumbing, all their materials are the...

Not if You like growing Legionnaires disease over the summer or some other fungus that will grow to plug the pipe and screw up condensate drainage. I just got roped into repairing/ replacing the...

Great job! Congratulations on becoming pro.

I always piped vents and outdoor air PVC ducts per manufacturer, My brain dead cheapskate boss hated it. He was a "just put a hole in the wall" moron. They must have upgraded inducer fans from the...

As far as roof equipment I hope there is an easy way to get up there for service. You could put a package unit on the roof and duct down to 2 top floors, that would cut out refrigeration piping and...

Thank you, I have a much better picture in my head. Wondering if its a half basement with a crawl space under dining room that is unpleasant. I see no need for a boiler just to run a heating coil in...

It would help with recommendations if we knew what part of the country you are in ( as requested). You must be in the city living in an old sandwiched four flat. I will try to help aaanh, I''ve seen...

News to me, thanx

I've never seen a 2" vent in my life, what type of equipment uses that? Time to call me a crazy old man and educate me.

The boys at Pro Press should come up with some shears for big pipe. Wall thickness could be a problem tho I guess.

Why shouldn't we install larger systems? Most of the vents that I put in were 4"

Now that's cute! Could be nice for sink jobs and plumbers.

could be a 5/16" square head bolt, 8 pt sockets have been around forever, it's good to have a full set, they work on pipe plugs too.

There is also a handsaw available from Sandvic 24" much like an old carpenters saw, works well for me with much hand sawing of wood in the past. Lenox makes stiff 18" replaceable blades for a "D"...

I was wrong about eccentrics in PVC, and it did not take long to get called out on it! Gotta love it

sweet, thanx for the education. never saw one around here, we don't get away with using PVC much.

Hinky right, makes me wonder about the regulators on the roof, a lot of ways to screw that up. May well be spilling out of the draft hood, no warm tall chimney, wind blowing all over.

7 numbers, sorry to ball bust you but I didnt want the kid to think he was alone, we all catch hell if whatever/ half the fun.

should be in the vertical as to not trap water, they don't make eccentrics in PVC

When the bladder tank is reasonably supported and piped from the top.

everyone who knows me would considerate a compliment, IDK?

I take it to mean after 5 am

Come on, I just saved your life. There may be more than one power supply going to that unit and I'm glad that I did not tell you how to open it up. Please post some more pics of chassis, I have the...

certainly need let down regulators if on a 2# system, playing with the main reg wont help much, too slow to regulate, need to check gas pressures everywhere and find new ways to do it if necessary....

Well don't hold me to any useful information. First thought would be an electrician but they don't work on these. Sounds like that old roach has enough electric coil heaters to warm up a warehouse....

Lots of variables to decide when and when not to trap. Never heard of a trap on a liquid line.

Try digging around, usually there is a user manual and an installation manual, you may need the latter.

when I move up in the world it will be a bottle of Gin and tonic water to ward off SARS

mine just has a weird abstract # on it

This is the safest site in the world, we do paranoia, politics, and all manner of conspiracies on the pro threads. Everyone has your SSN.
Put a piece of tape over the number!

You're far too inexperienced to jeopardize this site for help. Apply for pro-status, (not we) but certain techs are just busting your balls because sometime that is how it works, we can see a lack...

Because i'm not there to follow the wires and figure it out for myself, asking for tips on a garage heater, take another step up the ladder.

(A) follow the wires. You just sound so rookie.

I'm supposed to be the biggest "dick" ! Dad tries to keep us cordial.

We're not supposed to give you advice (as a non-tradesman posing as one). Everyone here has tried to help you out, give you ideas, point you in the right direction, we will always help in a safety...

While you are there you can jump it out for unit testing

JWas not saying that it does not need to be replaced, probably does. Need to find out why it failed.

Yes, that limit is going off for a reason, Modine heaters are the most neglected heaters on earth, they get hung and left forever w/o attention for decades until they stop because the owners don't...

Love the way you think! Chase the gas then chase the voltage drop. Nothing like inrush currant to screw with systems.

Every unit that I ever saw hangs from the top with threaded rod. The limit is there so the building does not burn down. Pull that flu pipe and make sure there are no dead birds in it, if it's rusty...

Thinking maybe you should make sure that the flu is clear, maybe clean off years of shit off of the heat exchangers. just guessing.

Did you, like, check incoming gas pressure?

people like to shovel snow onto gas meter/ regulator, next no gas, go figure. Does their gas range run on all four burners?

r u in the snow belt?

I was speaking of a different type of PRV, The expansion tank is actually one of the most important devices in the system and it has to be working properly. Get in touch with STEVEusaPA, he's a...

Yeah, that exhaust location looked very sketchy. Makes you wonder what happened to original chimney?

never heard of it or seen it, looks like clothes dryer vent pipe, sorry for confusion

I was referring to the flex pipe, not the wye.
