I have never heard a ticking noise from a SW igniter.
The igniter is actually a glow plug and has no moving parts. If your heater is used you may have to take it apart and clean it. SW heaters have a way of "growing" a white dust in them which may block the on off valve passage or the flow of vapor gas thru the heater. Note that there is no way for exhaust gas to leak into the car because the instant the vacuum seal anywhere is broken the heater stops pulling gas and does not work.
