how to open Munchkin for coil cleaning?

.

...but I can usually open things up and put them back again. This one has me stumped. Removing the front plate of the Munchkin T80 (wall model) involves taking off the six 10mm nuts, which I can do easily, but also one must "remove the 4 screws on the aluminum 1/2" NPT connector on the gas valve".

I assume this is where the gas pipe comes into the valve on the far left side. There is a female NPT connector held down by 4 screws, but it is brass and not aluminum. It makes sense, though, that taking those 4 screws off will allow the entire assembly to be pulled forward.

BUT...how do I get those screws off? In the wall-mount T80, there is maybe a 1" gap between the screws and the cabinet, so I can't get a screwdriver in there. I had to use a dental mirror to look at the screw heads, and they appear to be Phillips. (The floor Munchkins are shown in the manual as having the gas shutoff valve inside the cabinet, so there's probably more space.)

How do I get them off? Thank you for your help,

I'd suggest...

that you contact the manufacturer. Doesn't sound to me like you know enough to keep yourself out of trouble.

Good advice.

Don't fool around. This boiler is is touchy to say the least.

Get a factory trained technician to do this service for you. There's no need to mess wth this thing if nothing's wrong either. Scheduled maintenance must be done by trained personnel.
