Don't you have to set sw1-2 to on for low fire gas pressure adjustment? Plus, doesn't the manual says to set hi fire first? Great video by the way. Thanks
Good catch on setting the high fire first. You are correct. Thanks for commenting. SW1-2 just keeps it locked into low. It actually tells the board that you're using a two stage thermostat so if it doesn't see a call on the W2 terminal it will not go into high fire even after fifteen minutes.
I don't recommend draining a boiler regularly. Every time you introduce new water, you introduce oxygen with it. Oxygen is corrosive to a system. The only thing I would drain is an expansion tank if it is an open style, non-bladder. Sorry, I don't have a video on that, though. Here's a link for a commercial boiler with two tanks. ua-cam.com/video/IPURWpQqL8E/v-deo.html . The principle is the same. Close off the tank from the boiler system and drain the tank. There's not always a bleeder to let air in as you're draining. That gets tricky so here's another link with a little trick for those. ua-cam.com/video/tWzZ6H57rQI/v-deo.html Hope that helps!
You don't have to wait for manifold gas pressure to drop first before making adjustment for hi fire? Like when you were doing adjustment for low fire. Thanks
When the furnace starts in low fire it actually starts in medium and then drops to low after about 10 seconds. That's why you have to wait. When it starts in high fire, it starts right in high fire. No need to wait for it to drop. Good questions. Thanks
