Pentar Master Temp not igniting

[db1234]

Hello,

My Master Temp 400 kicks in, I smell gas and hear the pilot trying to start it.

It tries this a couple times and eventually gives the service heater LED.

When opened up, the only alarm LED is LED 11, which I believe to be service heater as well.

I've seen another thread which mentions that the drum at the bottom (burner) could have water in it. Due to the heavy rains and the chimney proximity beside the slanting roof of a shed, I'd like to check for this.

Could someone verify if I undo the bottom bolt on the right, not the one facing me?

Would the bottom bolt facing the right be one I can undo safely to see if it's holding water and needs draining?
Thanks

Go to 19:00 in this video to see the manifold bolts. You can remove either of the bottom ones to check for water.

Check this reference for more information.

Thank you very much. Lots of info there. I'm hoping for the cheap and simple solution!

To check for water in the heat exchanger box, you take out the lower bolt in the front. Not the drain plug, that is used for winterizing.

Merged them.

Thanks for merging, I thought I double posted, sorry.

Thankfully no water when I took out a bottom manifold bolt. Checked and see 120 vac when I disconnected the ignitor leads, turned off the gas and turned it on. Ignitor is reading infinite resistance so I'm hoping that's the one and only issue.

Thanks

To answer your question, yes, the bolt on the right not the one facing you (in your pic). Although, it would take a lot of rain water to fill the firebox. and since the exhaust exits laterally, i dont think your issue is rain water. Check your igniter.

When I disconnected the igniter, the resistance was infinity. I ordered a replacement and just replaced it. All seems good now.

Thanks
