Keith.
I know there can be faulty gear but:
The breaker CANNOT be the problem, that only ensures the
wiring will catch fire before the heater does.
The amount of recirculatory airflow, which is the cool intake, and hot air exit side has to be free flow. Having the intake in a mostly sealed cupboard seems to be a large oversight by installer. ie, not much idea of the unit. It may not be specifically mentioned in the blurb but do you know of any heaters which run with a severely restricted intake airflow?
Do you really think the suppliers run a diagnostic
test? They simply replace stuff to make things work. Yes, they know about replacing heater glow plugs of course.
The
wiring plug. DO you mean to say the supplier could not
test it because they don't know enough about what they sell to simply connect the wires in same combination, no matter which plug has been fitted to
wiring. Not very good at doing anything are they?
When you say , "the heater tripped out" is it that it stopped? What tripping of what was happening? Sounds like the diesel flow is restricted or tank cap vent not
venting. You DID
test it with cap off didn't you? Replacing the pump and filter is not a solution if filter is clean and passes fuel and the pump delivers to the burn chamber. There is always some smoke and burping as you start after a system fuel line bleed.
If the heater is only drawing around 2 amps at start up, then the heater glow plug is NOT working and of course the flame failure will say no flame because the hasn't been any flame.
The supplier still holding to the breaker issue indicates they have no idea of anything related to the heater apart from some info they have been forced to learn because of trouble from customers. They buy a few additional bits of heaters to have the required "stock or spares" for warranty. They will guard them closely and blame anything they can. PS. If these glow plugs are a bit voltage sensitive, then the thin Chinese
wiring will allow them to work/heat and last. If supplied with great
wiring, no voltage drop, while operating on a system having higher than normal system voltage it may begin to burn out any heater glow plugs everytime. Perhaps the thin
wiring is there for a current control reason. They will be made to a minimal spec. Just observations from what has been said.
