Hunter Herald 5 Inset Stove - Flue options?

Benster

Hi folks, I'm thinking of buying one of these soon to put into my current open fireplace. Opening is 16" x 22" and is going into a clay-lined flue (so far as I know - years ago I saw the estate being built and saw flues sitting on palletes in plastic wrap, waiting to be installed). We have only ever had an open fire going in this, without problems, and had it swept just last year.

In other people's experiences, would we be ok with the chimney flue we have or is this a case for putting in one specifically designed for stoves? To be honest, I want to do this right if I can afford it, but if it adds 100's to the cost it could be a deal-breaker.

The online manual for the Herald 5 Inset says "The diameter should not be less than 150mm and not more than 230mm. If any of these requirements are not met, the chimney should be lined by a suitable method". Not knowing a thing about standard Irish chimney flue diameters, what are the odds that ours meets this requirement?

Thanks for any help,

B.

6 inch twin walled stainless flexi flue liner and anti down draught/anti bird pot hanger cowl.

Installed into my chimney for a Stovax Riva 66 multi fuel inset stove.

You really need to line your old clay chimney liner with flexi flue liner if you want your stove to work propperly.

Thanks that Paddy. This looks like it's turning into a big job. Is that liner able to be pushed up from the fireplace or is a job to be on the roof for?
The cowl I'm not sure about, we never used anything like that for the existing chimney with the open fire and if I can avoid having to get up the roof I will. The chimney pot already has a birdcage thing on it anyway.

Cheers,

Its a roof job, 2 man job aswell.

the liner has to be pulled down from the inside while another person "feeds" it down from the top.

And you need the cowl on top aswell.

You HAVE to use a chimney cowl,as you will have to secure the liner to the top of the chimney,or else the liner will simply just fall back down the chimney.The cowl also prevents wind and rain from comming down the liner and affecting the effectiveness of the stove.

Oh,and for the sake of an extra 8 euro,buy a flue liner nose cone.

Its a cone shaped piece of metal,you screw the liner to the nose cone with 3 self tappers,then you tie your rope onto the nose cone point,drop the rope down the existing chimney with a lead fishing weight on it or a spark plug so the rope gets down the chimney to the fireplace.

And as 1 man pulls the rope down the chimney out of the fireplace,the 2nd man is up on top of the roof feeding in the liner.

The nose cone just makes it so much easier to get the liner down the chimney.

Oh and this next bit is VERY IMPORTANT.

The flue liner will have directional arrows on it every meter or so,these arrorw point upwards from the fire place torwards the roof/chimney pot.

This is to prevent condensation forming inside the liner.

Make sure that the arrows point upwards when installing the liner down the chimney.

Paddy 147 - was it a normal chimney you put the inset stove into? I have a woodburning Stovax Studio 2 stove but I have a false chimney but the slabbing put around it was just pink fire board gypsum based. Also single wall flue was used from top of the stove to the ceiling, What would be your opinion on that? I'm thinking of taking down but was wondering did you or anyone have a suggestion on what type of fireboard should be used? Supalux, hydroboard and Promatec were mentioned but hard to know what is best to use

Normal old 1950s chimney.Fireplace and chimney breast was more or less demolished and rebuilt to suit a Stovax Riva 66 inset stove.

Stainless steel Twin walled flexi flue liner pulled down,from the chimney pot to the fireplace,I was told by every fireplace company that I visited,that any solid fuel burining stove should be fitted out with a stainless twin walled liner.

So thats what I went with.:)

Look from inside the old fireplace/chimney.:)

Exell Industries out in Coolmine.

It was about 340-350 euro for around 10 meters of it,a stove connection pipe,and also a "pull cone".

The "pull cone" is for pulling the liner down through the chimney with a rope,from the roof top/chimney pot and out into the fireplace/opening.
