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.

You're welcome, Lee! I looked at the Monitor 40 thread you shared. From what I found, the Monitor 40 is a vented wall heater with a different burner pot design compared to your Toyotomi LC‑32 laser heater. The burner chamber size, airflow and heat distribution are all different, so a mat that works for a Monitor might not behave the same in the LC‑32.

Since the heater isn't lighting, a few things could be causing the issue:

• The mat material, thickness, or weave may not be suitable
• The mat might not be seated properly
• There could be something else entirely unrelated to the mat replacement

I understand the £60 cost is steep for a burner mat. Since I’m not an expert, it might be best to either wait for hawkins111 to weigh in, since he may be familiar with this model, or contact a Toyotomi dealership to get the exact specifications for the LC‑32 burner mat. They can also answer your question about whether a fibreglass-type material rated around 500 °C (950 °F) is sufficient. Getting the right specifications could help you find a suitable alternative material more safely if you need one.

It will be interesting to hear what hawkins111 or a Toyotomi specialist suggests. Keep us posted!

This type of heater is not sold in America by Toyotomi USA. I have never seen one and don't know anything about them. Sorry.

Thanks for checking in, Tom! I appreciate you taking the time to look at this.

Lee, since Tom isn't familiar with the LC-32 model, I'd recommend reaching out to a Toyotomi dealer or service centre in the UK that handles this heater. They should be able to confirm the exact burner mat specifications and help troubleshoot why it's not lighting.

In the meantime, a few things to check:

• Is the mat seated properly in the burner pot?
• Are there any error codes or unusual messages when you try to start it?
• Did anything else get disturbed during the mat replacement?

Getting the correct specifications from Toyotomi will give you the best basis for either buying the exact part or sourcing a suitable alternative safely.

Please keep us updated on what you find out. Your experience could help others working on LC-32 repairs!
