First time on the forum. My question or issue is that I can not get a draft reading with a nanometer I have a keystroker koker with a chimney and barometric regulator Purchase a new nanometer with no luck. Have had no issues with this till now. Only thing I have done is replaced the rain cap. Any suggestion

What model manometer do you have and where do you have the probe inserted? Pictures would definitely help us diagnose it...

Have you checked the chimney and connector pipes for obstructions? I'm assuming you are clearing the connector pipes of fly ash as required. It's a good habit to use a mirror to check the chimney for obstructions when the connector pipes are off.

The other side should be open to atmosphere. Many add a couple of inches of tubing to let it hang and avoid dust.

How much fluid did you add, can you see it in the meter part?

It must be level and zeroed with both tubes just in the atmosphere.

Many (most?) reverse the tubing from the instructions so the larger portion of the display shows draft, albeit positive when we know it is the same value but negative. Otherwise you only have a very small portion to read.

Let us know how you make out

Just so you know, for your stoker stove, you need to insert the manometer probe into the stove to read the over fire draft. Per the manual, it's to be set between -.02 and -.03 during a long run. There is a hole in your door frame to take the draft reading. The draft in the stovepipe is not really relevant for a stoker unless there are issues. Stovepipe draft will likely be between -.04 and -.06 during that same long run but the key is to set over fire draft per above.

As for your lack of draft, Richard hit on some key points. Was the stove and stovepipe cleaned out after last season? Was the chimney checked for obstructions
or internal damage (holes) when you replaced the cap?

Double check that the other tube not in the stove is open to atmosphere. It works by comparison. If both tubes are hooked up with same draft- say one was in chimney and one in the stove door- it would read zero

You can also blow gently across your tubing (pull out of furnace or pipe) and you should see the level moving. Just be careful not to overflow or pull fluid out

Welcome to the forum!

It seems you're experiencing issues getting a draft reading with a new nanometer after replacing the rain cap on your keystroker koker with a chimney and barometric regulator. Here are a few suggestions:

Check Installation: Ensure that the nanometer is installed correctly and securely. Double-check the connections and make sure there are no leaks.

Calibration: Verify if the new nanometer requires calibration. Follow the manufacturer's instructions to calibrate it properly.

Airflow Obstructions: Inspect the chimney and barometric regulator for any obstructions or blockages that might be affecting the draft.

Compatibility: Confirm that the new nanometer is compatible with your keystroker koker model. Check the specifications and requirements.

Rain Cap Replacement: Since the issue started after replacing the rain cap, ensure that the new rain cap is suitable for your system and is not causing any airflow restrictions.

If the problem persists, consider reaching out to the manufacturer's customer support or seeking advice from experienced users on the forum for more tailored assistance. Good luck!

Hey bot, do you know that a nanometer is a unit of measurement?

No offense to the OP. I assumed it was a typo. The bot comments lately are getting irritating.
