What is the correct thermocouple i need to buy to replace the one on the heatilator & heat-n-glo propane gas pilot assembly 4021-737 ?

# 2103-512 - Amazon's Choice. It was very easy to replace, I had it completed in about 30".

Is this compatible with my heatilator lp gas, mod# nd42361, ser# ga1670691 fireplace?

Pre serial number GA1587914 uses 4021-737, Post GA1587914 uses 2103-011. So you need 2103-011.

Will this fit a heat-n-glo model 7000 xlt?

the replacement number is 485-511a for propane and 485-510a for nature gas
