Toyotomi (Zibro) LC-32 Burner Mat Replacement

[Wadey68]

Hi,
my first post, so thank you all for being here!

From reading the forum on these types of heater I think I have identified my problem as I have a large hole in the burner mat.

I have cleaned the old mat and residue off and replaced the mat with a silica fibre woven cloth I used Victas fire cement and bedded it into that.

How long should I leave it before I light the burner? I have it in the oven at 100C to help the cure.

Many thanks,

Lee

Hi Lee, welcome to the forum!
Good to have you here. I’d suggest waiting for hawkins111 to respond. He has shared a lot about Toyotomi heaters in the past and might have some useful insights on curing and the burner mat.

In the meantime, here’s what I found online:

• Fire cement usually needs a short air-dry, then gentle heating for a couple of hours before full use. The 24-hour wait you mentioned is safe but a bit more cautious than most guides suggest.
• Oven at 100 °C isn’t officially recommended. Too much heat too soon can crack the cement. The safer approach is to heat it gradually using the heater itself, starting on low.
• Burner mat material — I couldn’t find confirmation that generic silica fibre cloth is an approved replacement. The official Toyotomi mat is made specifically for the LC‑32, so it might be worth checking compatibility.

This is what I could find online. Again, I’d recommend waiting for hawkins111, as he may have firsthand experience with this model and can give more specific advice.

hawkins111, could you take a look at this question about replacing a Toyotomi burner mat?

Hi TinyTool,

thanks for the welcome, and thanks for looking into this for me.

I cured it for about 3 hours in the oven, no cracking and it feels hard and cured. I tried to light it today with no luck.
The reason I chose the silica fibre cloth for the mat material was because of this thread

https://homerepairforum.com/forum/indoor-home-repair/hvac/monitor-heaters/12349-material-for-making-a-burner-mat-cloth-for-monitor-40

Maybe it is not suitable for this heater? I am quite open to trying different materials because it will cost me £60 for a mat from US or Europe. I can find no stock in the UK.

The original mat looks like fibreglass to me, 500c ish 950F ish? Is that enough?

Lee.
