I have just found out the ignitor for the gas burner has failed on our Truma Gas heater.

£100

Far too steep.

Has anyone found a cheaper alternative or replacement please?

I assume you have changed the battery and cleaned the contacts?

Funny how things go ours has just stopped as well.
lucky for us it was under £40.

it was sticking out of the top of the case. The last owner said it had always been like that.
well I pushed into position yesterday and ping. it fell to bits .
hence my post on this thread saying could it be this one.

Actually the one you posted is the manual version. It might well fit the OPs heater, from memory there may be a blanked off hole on the top of the case which it would fit into?

Good plan but it might be better to keep it for spare parts for yours especially if it has the electric elements?

Hi guys. I've just recently changed my electronic igniter for an old school manual push button type.

Was no way the electronic replacement was worth £100.

The replacement was easy to fit. From Amazon for £12

Took 10 minutes.

Just needed a metal hole saw and a wire to ground. Connect the igniter cable to the new push button and hey presto.

Heater fired up right away.

Here's the link for the one I purchased.

If just replaced our battery box with the same push button. But don't think I've earthed it correct as sometimes it won't spark and other times it will. Any tips? Photo of yours would be a great help. Thanks

Hi Busabasher copied your idea for the replacement of the piezo igniter. Although ours was already a manual I removed the Truma igniter by pushing it out of the casing and cut the bottom off as seen in the picture. Then enlarged the hole to take the aftermarket piezo igniter. Connected to existing cable and reused the cable which came with the piezo igniter and added a larger spade connected for the earth. Now fires up first time and only cost £9 from eBay. Very pleased.

Hey everyone,

I'm looking to replace my Trumatic Ultraheat 230V Auto igniter box, which seems to have failed, and I'd like to save myself the £90 cost of a new one by installing a manual push-button igniter instead.

I understand the part about drilling a hole in the heater for the push button—that seems straightforward. However, I'm a bit unsure about the wiring involved.

  • Is it just a matter of removing the Auto igniter box and disconnecting the brown and black cables from the terminals?
  • How exactly do I wire the new manual push-button igniter in place of the old electronic one?
  • Do I need to ground a wire as mentioned in previous posts? If so, what's the best way to do that?
If anyone who has done this modification could provide a detailed explanation or share some photos of the wiring setup, it would be incredibly helpful. I'd really appreciate any tips or advice to ensure I do this safely and correctly.

Thanks in advance!

Hey everyone,

I just completed the modification and swapped out my Trumatic Ultraheat 230V Auto igniter box for a manual push-button igniter—and I’m happy to report that it worked perfectly! Here’s a detailed breakdown of the steps I followed, in case anyone else is looking to do the same:

Materials Used:​

  • Manual Push-Button Igniter (Purchased from eBay for £9)
  • Metal Hole Saw (18mm diameter to match the igniter)
  • Spade Connectors (for the ground connection)
  • Basic Tools (screwdriver, drill, wire cutters/strippers)

Steps I Followed:​

1.​

  • Located the auto igniter box inside the heater compartment.
  • Disconnected the brown and black wires from the terminals on the box (these powered the old igniter).
  • Unscrewed the box and removed it completely, leaving the ignition electrode cable that leads to the burner intact.

2.​

  • Found a convenient spot on the heater casing for the push button. I chose a location that was easily accessible for manual operation.
  • Used a metal hole saw (18mm) to drill a hole for the push-button igniter. The hole needed to be slightly larger than the diameter of the igniter’s mounting threads to fit snugly.

3.​

  • Ignition Lead:
    • Connected the high-voltage lead from the new igniter to the ignition electrode. This was straightforward since the lead was the same type as the original.
  • Ground Wire:
    • The manual igniter had a spade terminal for grounding. I reused the cable from the old setup, crimped a larger spade connector onto it, and attached it to the heater's metal casing.
    • Made sure to clean the surface where I attached the ground wire to remove any paint or rust for a solid connection.

4.​

  • Inserted the igniter into the drilled hole and tightened the mounting nut from the inside of the heater casing. This kept it firmly in place.

5.​

  • With everything connected, I pressed the button, and immediately heard a strong spark at the burner electrode.
  • Turned on the gas supply, pressed the igniter, and the heater fired up on the first try!

6.​

  • Secured all cables with zip ties, ensuring nothing was loose or near any hot surfaces.

Observations:​

  • The heater now starts reliably every time with the push button. It’s a simple and cost-effective solution compared to replacing the auto igniter box, which would have cost £90+.
  • The entire process took me about 15–20 minutes, and the hardest part was drilling the hole neatly.
If anyone is thinking of doing this, I’d highly recommend it! The manual igniter works just as well, if not better, than the original electronic one.
