Halstead Bentley ?

On the contrary, I was a CORGI installer from 1971 until I retired in 2007.
In that time I installed and serviced a lot of gas boilers, And in every case the fan impeller was accessable INSIDE the CC and the fan motor and motor cooling fan was accessable on the OUTSIDE of the CC. So why are you asking me to prove that the fan is outside the CC when I have already clearly stated the above.
.
You say that two RGI`s can`t be wrong . I get the impression that so called RGI`s have a law of their own and the rest of us are stupid.
So perhaps, just perhaps you will admit that I am not making false claims and admit that you are wrong. Now thats what I call a senior moment.

I am sorry to say that you are wrong about the Puma and the only candidate which has been mentioned is the Halstead Bentley.
Don't you remember the Puma? Would you like to come and see one and I will even give you a coffee when you admit that you are wrong.
Of course there are trolls on forums who state that black is white just to be provocative.

The big sealed bit is called the combustion chamber cover, though the CC itself is really the smaller one inside with the flames inside! Semantics!
The big bit is the one DIY chappies shouldn't take off.
I wonder if the replacement circuit board was one for a puma P or a Puma E ? IF there's a number of components not fitted to the lower left part of the board, you have the wrong one.
The P board just has an absent capacitor, fairly centrally, about 10mm diameter.

Hi Tony.
Thank you for your invite but before I accept I must warn you that I would win this friendly argument for the following reasons:
If you visit the Diy gas section on this forum you will observe that it states “Gas work includes anything which involves removal of the combustion chamber cover or sealed boiler case cover”. As you should know, being a RGI, that boilers with sealed cases were restricted to the ones that worked on positive pressure within their combustion chambers, such as the Potterton Netaheat etc. And you should also know that the combustion chambers of the Potterton Puma and Halstead Bentley for example, have negative pressure and therefore it is not illegal for Diyers to remove these boiler cases. Perhaps other RGI`s would like to air their views on this.

The air flow switch may appear to be working, but if either of the flexible tubes to or from the switch are frayed or blocked, or if their connection points are blocked [ especially the one on top of the chamber] there may not be enough air flow [ when called for] to operate the switch.
The combustion chamber is the combustion chamber , wether it is negative or positive is in this context irelevant !
As far as gas safe are concerned the removal of the combustion chamber seal would constitute gas work!
What some one does as a diyer in there own home is a matter for them ,in most cases any rgi on this site will not advise that any diyer removes the combustion chamber seal & the reasons for this should be obvious ?? Must admit at times I have sliped up with advice & have been told off for it ? ( rightly so )

Wrong
The motor is bolted to the side if the fan how can one be inside and one outside
Wrong
Wrong
Of course it can its just a few screws. Are they breaking gas regs if they're not competent to test the safety of the appliance afterwards? Yes.

If you remove the casing from your boiler you will note that there is a small fan on the top, known as the motor cooling fan, by spinning this fan you will also be spinning the motor and the larger fan inside the CC.
Perhaps if I had stated that the boiler casings on positive pressure boilers acted as the CC you would have understood better.
If no gas related work was carried out on your boiler what safety checks would you have to carry out after refitting the casing. Considering that I don`t know what I am talking about , please reply as I am always ready to learn.
Spraggo, I can see your arguement for motor outside/fan inside but the point in question is the removal of the front panel or "combustion chamber door," most fans are totally inside this area, although the impellor is, more often than not, actually in the flue collector hood NOT the actual combustion chamber.
There was, I believe, a baxi solo that also had the fan motor on the outside but that is quite unusual.(I'll see if I can find which model)
