weird Munchy question

You can test it from DEEP in the outlet if necessary, it just means some running in and out, reading the meter and setting the boiler. IF the boiler is a 140M there is some space behind the HX in the cabinet where the PVC nipple is longer and you might be able to tap into it. Just be sure to seal the test hole well.

What would you do

if there was no way to insert your combustion probe into the exhaust pipe of a Munchie? This one disappears right through a wall and doesn't appear again until the exhaust outlet.

Push the probe as far down the outlet as possible?
