I installed a new Tt last month and have increasingly experienced a loud bang at ignition, which blows the condensate drain off. My installer had no luck in fixing, now the unit gives me an error code E02 and quit.
Has anyone had similar experience ? Any advice on remedy ?

I'm no TT expert by any means, but it sounds like delayed ignition, and sounds kinda dangerous.

My best advice would be to find a new tech that knows what he's doing.

What does the manual say about E02 code?

There are guys here who know these systems well, I'm sure they will answer soon... standby!

 

It seems like a Weil Mclain Ultra.

Silly question and not sure if it would even work or cause the issue.
Is it and LP model? Did you get a natural gas unit by mistake?
I know the water column at the gas valve is the same in the manual, max of 13 W.C., but the orfice need to be different. They use the same valve for gas or LP. They just change the orfice.

From the manual:
Prior to start up, ensure the unit is set to
fire propane. Check the rating label for
the type of fuel. Check the gas valve for
propane conversion label. If there is a
conflict or doubt on the burner set up,
remove the gas valve and check for the
propane orifice


E02 is failed ignition after 5 attemps. You need to find the reason its not igniteing. The chamber is getting saturated with fumes probably, hence the mini explosion.

Becareful.

Call Triangletube tech support first thug in the morning.
Something is not right... Might be the mixture screw is set to far open.
Did your installer put a combustion analyzer on it before he left ?

I have installed over a hundred of these any I have never had these issues.
I do not do many LP units.

The LP units have a knit burner head along with a different orifice. Check your boiler for a LP info on the rating plate. Most rating plates are behind the MCBA controller on the sheet metal.

If your running LP thru a NG boiler, I suspect this would be the results.

TT tech support can tell you if the boiler is LP by the serial number on the flip down plastic cover... PSxxxxxx.

They will help.

 

What TOHeating and lawrosa said.

First, check it's the right orifice and setting for your gas.

Second, check the gas pressure (both min and max - min should be with all gas appliances in the house running full bore, max should be with all appliances off).

Finally, if both of these are ok, call TT.
