A thread was recently necro-ed asking for info on diesel heaters; necro threads are an issue on the forum because of its default setting for viewing threads hence I've started a new thread.
The first attachment is the full manual for the generic Chinese diesel heaters I found somewhere on the net the second is the FAQ from the extensive Facebook group, the following notes are from my own experiments:
----
Bleeding:
Hold the "OK" and "Down" buttons
When "Off" flashes press the "Up" button
----
Ryco Z675 fuel filter works well
----
(Don't mess here unless you know what you're doing)
Config menu - Settings button 3 times until padlock icon
PIN = 1688 press OK after each digit
----
To toggle between temperature and pulse rate:
Press OK twice
Press Settings and Up together
----
I suggest you do not run these heaters on thermostatic temperature control their design is not suited to it. Instead use the pump pulse rate to manually control temperature, in my large caravan in Victoria I find the minimum setting of 1.6Hz works 95% of the time and when the van become too hot I crack a window at each and and opposite sides to balance things out.
It is a good idea to run the heater at maximum for 20 minutes once every few months.
Edit:
This is the original thread which contains a useful table from "Are We Lost".

Booming noise? Mine is a bit noisy on startup but then settles down at normal speed. I would hardly call it booming, but certainly audible. I bought a second muffler for mine and can just push it onto the end. That makes a fair bit of difference. I am not sure if the extra back pressure affects the heater, so rarely use it. Just ensure your exhaust pipe is not transmitting noise through direct contact anywhere onto the chassis.
For the pump ticking noise, stopping the pump body from touching anything makes a big difference. I have mine wrapped in insulation and held against a piece of foam with cable ties, rather than use the supplied mount. The fuel feed line from the pump to the heater also generates noise. Just letting the tubing touch a panel transmits noise. So I bought some soft rubber moulding with a hole in the centre and fed the tubing into that. Some fuel lines vary. The thin translucent variety benefit most from that strategy.

I used an engine mount to fix the pump to the chassis,even better if you can keep it of the chassis as it tends to amplify any sound.
Also disconnect and turn the Pump around then extend both inlet and outlet fuel lines so they have a 180 Degree bend to travel around then pulsing movement of the pump does not travel back along the fuel lines.....the bends absorb the movement and the sound. (I have also used this method when installing similar fuel pumps in cars ......has a good effect) The less "fixings" that the fuel lines have to the body the quieter it will be.......KB

Has anyone got any tips re a product or way to wrap diesel heater exhaust to deaden the booming noise please?
They should not make a booming noise indeed the exhaust of mine makes hardly any noise at all.
I met a bloke, somewhere, about two years ago and he was complaining of the same issue, it transpired his heater did not have a silence fitted simply an open end exhaust pipe. They should have a silence similar to this:

Looks like you have also changed the original clamp to a rubber lined hose clamp, looks good to me, I'll give that a try,. thanks Ian

Thanks everyone, all useful comments. My exhaust is attached to the chassis so that must be my error. I'll shift it and wrap it in fibreglass stuff (obvs heatproof and not over the outlet).
My pump is mounted similarly, under the van. Tick tick tick. A job for when it's not raining.
Learning.....

I don't think having it attached to your chassis would make it any louder as most would have it that way, the exhaust is a little noisy on start up but after 10 mins it should be quiet, as Mike says do you have a silencer attached to the end ? Ian

Hi Mike
Great information, have now stored this for future reference.
Thank you.
I don't notice the exhaust but I would like to know how to deaden the ticking noise from the pump. Ian

This guy talks about how he fixed the ticking noise
