Abstract
A control module in a hot surface ignition system includes a microcomputer programmed to provide a pre-selected igniter warm-up time period for enabling the igniter to heat up to gas ignition temperature during normal system operation, and is further programmed to provide, for test purposes only, an accelerated igniter warm-up time period which is shorter than the pre-selected igniter warm-up time period but sufficiently long for enabling the igniter to heat up to a temperature sufficiently high to ignite gas. The program for providing the accelerated igniter warm-up time period is automatically executed in response to a unique signal effected by the control module in conjunction with a detachably connected test device.
