Hello all, looking for some help. I have a hayward h350 IDL2 gas heater. It is wired direct to fuse panel, no timer in between. Keeps blowing F2 fuse when i turn it on. Replaced fuse still blows. Replaced transformer still blows. Talked to hayward tech on phone,went through some tests with him and he said was transformer, bought new transformer installed and still blew same fuse. Im at wits end with this thing. Please help.
Thanks greg
 
First thought is, put a GFCI breaker within easy reach of the heater.

No idea on the fuse issue. Is the unit clean, or are there objects in the wiring that could be creating continuity/short between connections?
 
Wiring goes through house about 5 feet into panel with circuit protected breaker. No breaks or anything touching, it has been running fine for 2 months then all of a sudden this issue.
 
I TOOK OUT BOTH PRIMARY AND SECONDARY PINS TO THE FUSE BOARD. TURNED ON POWER TO UNIT, FUSE DIDNT BLOW. THEN I PLUGGED IN PRIMARY PIN FROM TRANSFORMER FUSE STILL DIDNT BLOW, WHEN I PLUGGED IN THE SECONDARY PIN THE FUSE BLEW, THAT IS WERE IM AT.

THANK EVERYONE SO FAR FOR THE HELP ANY OTHER SUGGESTIONS?
 
Could be something on the board, but you'll need to disconnect everything from the board except the transformer, then reconnect each component one at a time. Here's the diagram:[attachment=0:3puo89m4]H350 Wiring.JPG[/attachment:3puo89m4]
