Answer: 
Yes, shut the boiler off and add it directly to the boiler water tank. Then turn back on immediately and make sure the thermostats are turned up high. You want the water to be hot and circulating.

Rated 5 out of 5 by from Works as advertised! A week before heading out on vacation I discovered a leak in a pipe joint on my boiler. Not having enough time to get a plumber in to repair the problem I tried some plumbers putty and other temporary sealants to resolve the issue. Each of these seemed to slow the leak down, but did not completely stop the problem. With just a couple of days left I decided to give this product a try. I followed the instructions unscrewing the pressure releif valve and pouring the product into the boiler. After reinstalling the releif valve I fired up the boiler. I was stunned to see the leak completely stop within minutes. I held my breath as the boiler pressure rose as this is when the other products failed. No sign of the leak reappeared. I checked the boiler over the next two days and was happy to see that the boiler remained dry and the water level in the boiler remained intact. This is a wonderful product!

Rated 5 out of 5 by from Must have for outdoor wood burner users I confess I was lured into purchase of the cheap stainless steel ( not stainless at all) Canadian manufactured outdoor wood burner boiler. Even with keeping the required chemicals in the water at all time within three years it leaked like a sieve. Rusted in every seam. The real problem is this so called stainless steel is almost impossible to weld as compared to mild steel. This boiler was guaranteed 10 years except if it leaks then you own it. This boiler liquid has saved my boiler. Period. Whether it is the tubes inside the firebox leaking or the seam at the lower rear, this stuff works with absolutely no issues for the air to air heat exchanger or the water to water heat exchanger, the circulating pump, or the piping/valves. Better get some and keep it handy.

Rated 5 out of 5 by from Performs as described. Used in an outdoor wood fired boiler that had some pin hole or smaller leaks. Followed product instructions and leaks stopped almost immediatly. Has been about a month since added and no leaks.

Rated 5 out of 5 by from This product works wonders. I had a leak in my boiler and it keep putting out the piolit light, had to do something so I figured I will try this stuff; I am really surprised with the results.It didn't only stop the leak but when it dried it showed the size of of it. I would use this product again if needed to.
