Firebird Heat PAC 70 Boiler Door Sheared Bolt

Timfy

The boiler door gasket had perished on my Firebird Heat PAC 70 boiler.

The door had never been removed in many years and the inevitable happened... I sheared one of the four retaining bolts on removal. Obviously with one missing the door will no longer seal and I have left the boiler in an unusable condition.

Question to those in the know: Is this retaining bolt welded to the boiler itself or would a bit of brute force and a sheared bolt removal kit do the job?

Please note that all work undertaken will be checked off by a heating engineer and I'm not a stranger to tools, despite my eff up!

Now there is a problem that I often thought I would have, but so far so good. I have given it consideration and I have came up with a couple of possible solutions.
1. Weld a replacement stud on to boiler.
2. Weld a tag onto door and boiler.
3. Make up a clamp to hook onto back of boiler, or wrap completely around it.

Re 1 and 2, You have to be careful, as you are working on the water jacket.

Yes its welded to the boiler outer shell, use an angle grinder with a cutting disk to remove whats left, and get some 10mm threaded bar (or cut up a bolt), drain the boiler and weld on the new stud.

(draining the boiler is a must, if not the weld will not be successful)

Do not use the boiler in the condition it is in now.

Thanks for the above information guys... It has however confirmed my worst fears!

I'll have a word with a few of the local welding firms and see what's feasible.

The clamp solution is intriguing, at least for a temporary fix... It is an external unit so no danger to health.

Thanks again for taking the trouble to reply.

a nut splitter is the only way to remove some of these stubborn feckers
