Casting a vent?
 
I am thinking of casting my vent for my 42" oven. The instructions say to cast it using a form etc. They do not say if it needs to be a special type of refractory concrete or just regular concrete.

Will regular concrete handle the heat in the vent/chimney?

Cheers

No: The vent area, particularly down near the oven, gets very hot. You need to cast it out of refractory, or build the transition up with firebrick.

to add to dmun's comments - be sure to use a castable refractory, not Refmix, Heatstop, or the fireclay home brew mortars. I think various manufacturers also offer insulating castable refractory as well.
Sorry for the lack of specifics, it has been 1 1/2 yrs since I actually researched this myself (opting to stick will brick, a Duravent transition plate and Duravent pipe for a chimney)

A quick and easy solution to this problem is to cut your transition out of stainless steel and tack it together as I have just done for Hendo's oven (pic)
I will arrange to fit it with the lights on Saturday with a few small dyna bolts located in the centre of the firebrick archways.
It also makes the fitment and aiming of the oven illumination a breeeeze.
