25 PDVC vacuum test

[N.E S4]

I don't know if you noticed that Mike Holton, who replied above, works for your stove's manufacturer. He is a resource we all look to for understanding of the stove's functioning.

What is mike's user name? I'll be sure to PM him. I like to tinker hopefully he doesn't mind. Most manufacture does not like people to tinker with their product as it would void the warranty. I've been tinkering all my life from radio control engine to Ducati, and now pellet stove.

My point was that he has already given you sound advice which you brushed off.

I didn't know he gave me advise? I don't know mike.

And post 23. In particular the last line of that post.

Ok that post. He was explaining about air density hot it affect the vacuum. This is after I've already determine it's a faulty vacuum switch.

I didn't bushed that off, I understood his explanation.

From post 23

remember the velocity of airflow through the system is what creates the amount of vacuum needed so things that overly restrict the velocity of thhis air also reduce the amount of vacuum pressure available to the switch

The vacuum switch is the messenger. It may or may not be the cause of the fault. Anything that causes a loss of vacuum will result in the switch dropping out.

And that is why heat seeker was asking about your vent system and I was pounding on a good cleaning job.

An improper venting system is a restriction, improper OAK system is a restriction, crud in the stove from above the burn pot and to the venting is a restriction.

Restrictions become more important as the need for air increases as you go up the heat range.

How about if the room air blower is not working good or a plugged. It would raise the air temp.
going out of the stove not into the house? My 2 ct.

its possible but more likely the unit would hit the high limit and shut down from that before it would drop vacuum

It is official the vacuum switch was bad. The new switch came in today I had it installed the stove is running for 4 hours now without any issue. I had the heat range up to 8 for almost an hour.
