As long as you have the required grade, P traps, and gosenecks you will be fine.

How much additional charge did u have to add?
What make of unit did you put in?

I'm sure you know all this stuff but I thought it might be good information for some other members.

I have had the exact same thing happen to me. I once had a engineer lead me to a 1,000MBH boiler that was not working. After I made the repairs the engineer told me it was the wrong boiler. He tried to tell me it was my fault and it should be free....LOL

I had no model # and he called me out. Some people are unbelievabe.

It's a really odd test. I remember when I wrote it I was not sure if I passed or not. The problem with the questions is that some of the multiple choice questions will have all right answers and want you to pick the most right.

The suspence will play tricks with your head. I thought I failed the plumbing red seal but did very well.

On a side note I write the HVAC/R red seal test in 5 weeks ( fingers crossed )

I thought u didn't need a vac pump and gauges to install those ductless split systems- I thought that the line sets were pre-charged with piercing fittings on the ends
What brand ive never seen one I didn't have to vacuum down. Every brand I have installed had flare type fittings on the line sets. They were capped on the ends but as soon as the caps come off there will be moisture. Not saying that a unit with precharged lineset dosent exist I just haven't come across one yet.

Apparently they are/were pretty common in the mobile home construction.

Must look ugly with the extra length of piping that will be coiled at one end....

Let the hackery begin!!!!!

Okay now you got it, so what is the cv of the propane air mix? Okay it is 52% gas to 48% air mix? so we can confirm the specific gravity of the mix is around 1.286. and the cv is around 1375 btu per hour give or take.If we take the cv of propane as 2500, divide 52 by 100 we get, 0.52X 1.52 the sg of liquid propane and then add 0.48 x 1 for the sg of air and we get 1.2704 sg. If you take the 52 % and divide it by 100 and then times the cv of propane 2500 cv you will get a new cv of 1300 btu per hour!

I thought the air fuel mixture for propane was 25:1. How are you getting the 52% ?

It is 52 propane to 48 air, Iam burning a propane air-mix what is the sg and btu per hour?


OHHH ok. think my numbers are for combustion air requirements, my mistake.

Red seal plumbing
Red seal refrigeration
Red seal electrician
Gas A ticket

Then become an instructor at the union school

In two weeks ( hopefully ) I will pass the refrigeration. All that will leave is upgrade to A Gas then start on the electrical.

Yep Thompson rivers, I had searched for 2 years for an in class study course, I looked at BCIT and even had the credit card out to pay! TRU usually does the course starting in march to the end of april. Well worth it marty is smarter then most of us, plus he is a great teacher, he is very methodical probably the best I have ever seen! As an aspiring teacher you can learn from him, he disregards a rambling textbook quickly as just filler then slows it up at the key points and takes it above and beyond. His questions are mind blowing and honest truly a master!

Very rarely do instructors get such high praise.
I will look into the class

LG makes nice units. Very quiet inverter condensers. A little pricey, but competative with the major manufacturers ( Dakin, Fujitsu, Mitsubishi )

The AO smith cyclones keep us busy on the service side. I would never install one ......

There is a laptop connection on the far left under the capacitors. The unit can be tested through the Novar board as well for maintenance testing.

Please tell me they have gotten away from serial ports on the newer stuff?! Boilers are still using that old time crap.

I don't know what you mean by serial ports.....

A type of adapter used to connect to the system so information can be manipulated. http://images.yourdictionary.com/serial-port Here are some pictures. These ports are super slow compared to USB which in itself is very slow compared to other connections.

Yes those are still used on newer equipment. I though that might be what you were talking about. I always call them 21( or what ever # ) point connectors.

I would pay the $675 to have it delivered. I would also buy the flatbed so you could transfe your backhoe if ever needed.


It's the best of both worlds.
I guess you are right ..

It would take minimum 5 to.6 trips maybe more ..

That would be 6 hours driving and time to load and unload ..

So more like 12 hours or more ...

At 675 I can spend that time making a lot more than that ..

Now your thinking clearly. I would much rather do 1 furnace re and re than work hard for 12hrs.
You could also do 2 HWTs and have it all paid for.
