1 Base fixing

 

Firstly, remove the ash pan, log bar and firegrate. You 
will then see a pre-drilled hole in the centre of the 
base of the stove. 

When using this fixing method, carefully push the  
insert into position, locating it precisely in the fireplace 
opening before marking the position of the drill hole 
on the hearth through the stove base. Allow for some 
compression of the rope seal at the back of the stove 
to ensure a good seal between the stove and the fire-
place front. 
Remove the stove and then drill an 8mm diameter 
hole in the hearth. Fit the steel plug (or alternative) 
in the hole and carefully re-locate the stove. Fix the 
screw through base hole. Be sure to use the correct 
drill bit so as not to damage or crack any decorative 
hearth plate. 

See below

2 Front fixing

There are also two additional pre-drilled fixing holes 
on either side of the stove fire chamber opening that 
can be used to attach the stove to the fireplace (

see 

below)

Carefully position the stove within the fireplace  
opening and mark the two holes on to the fireplace 
front. Remove the stove and carefully drill the holes 
using the appropriate drill bit and insert the screw 
plugs. Re-position the stove and insert and tighten 
both screws. 

Remember,

 if you are fitting a liner then the liner,  

attached to the spigot, should already be dropped and  
positioned inside the chimney before the stove is fixed 
in place.

Creating an air-tight seal 

You must ensure a good seal between the back of the 
stove and the face of the fireplace. This is especially 
important if you are not using a liner since any air 
leaks here could impair the performance of the stove 
and also render it unsafe. 
Fire rope has already been attached at the back of  
the stove (allow for this in the base fixing method). 
Uneven surfaces such as stone may need additional 
sealing. The front fixing method will increase the  
security of this seal by drawing the stove tight against 
the fireplace face and this is therefore the preferred 
fixing methods when a liner is not used.

Remove fire grate to  

access base fixing hole

Lift the Fire Fence upwards 
and remove

Lift the Fire Grate upwards from the front 
and remove (you may have to push from 
underneath)
