the dome showed up today. i am going to use a metal cover over the dome.i am getting this done at a local shop. i need to determine the height of the cover i have two inches of floor insulation . i need to know if the layer of sand is needed if so i have to account for the height of the sand. so far i am looking at the dome height plus two inches for the floor insulation, 4 inches for the blanket and possibly 3/8 inch for sand. is the sand used to level the floor ann extra insulation?

[thezaman]

thinking about the question the sand doesn't the height of the dome but the height of the floor. without it the doom will be to high from the floor

is the sand used to level the floor ann extra insulation?

No, the sand has no insulation value. It is the minimal amount you need to level the floor.

i have all of the parts to assemble my portable oven. i have a few questions on parts and assembly . question one; there are two bags of mortar included a small and large bag. which is the high temp mortar and what is the other?
in looking at the assembly guide i doesn't look like there was any sand under the floor should i use it ? i want a low dome so the sand will raise the floor . if you do not use sand should the floor be mortared to the insulation.

If your floor sits flat on the insulation, you don't need it. If it wobbles, you need a leveling agent.

Hey thezaman,

The small bag is an additive that makes the mortar easier to work with (more sticky and better adhesion while it dries). We have started pre-mixing the additive to keep it simple, but clearly your mortar was not mixed. Just thoroughly mix the two together while they are dry.

I have been thinking about the floor for your oven, and I am leaning toward your mortaring the floor in place because the oven will be moved. It really is 6 of one and half a dozen of the other (both methods are perfectly valid), but you have a little less change of the floor moving if you mortar it down.

You should have enough mortar to do the floor, the chimney and to seal the dome to the FB board at the bottom.

Let us know how it goes.

great, i will be moving ,now i also noticed that the oven was set on the board before the floor was laid, is that the right sequence? i want my dome low, so a light layer of mortar over the insulation board will be o.k. as long as the floor is smooth?

[james]

First the board, second the floor and third the dome.

The mortar (or sand) layer will not raise the floor, it is just a thin layer that will allow you to set the floor smooth and level. The dome rests directly on the board (no mortar).

thanks, now if i overstuff the top of the oven and slightly compress the blanket will that hurt the heat retention of the blanket? this will be my last dumb question till final assembly. thanks,larry

Hey Larry,

A little compression on the blankets on top is fine. You are in good shape with your dome insulation, so use what you have and it will be good!
