Heat N Glo, Heatilator, Direct Vent Fireplace,Natural Gas（NG） Pilot Assembly 485-510A / 4021-736/2103-010

Fit perfectly, worked very well and only moderate skill and patience needed to install.

Easy replacement for unit with bad thermopile. Take your time and it's pretty easy to replace

Was exactly the part we needed to replace.

exact match for the Heat N Glo part. $59 versus buying from Heat n Glo $171.....all fittings wires and flex tubes were exact match. The original lasted 20 years...I hope this assembly does the same.

First one ordered went out in 2 weeks and I thought it was a fluke so I ordered a replacement and when the replacement showed up it seemed to work and then 4 days past the return window the part broke again and left us without heat in -20 weather and left us scrounging to figure out how to survive and get a new part. Please do not buy this part. It will only last you a few weeks and you will be out your hard earned money.

Just like the original but 100$ cheaper

Great parts and fast delivery. It was a relatively simple repair with the preassembled pilot light components. Lit off on the first try.

Repaired fire place at a fraction of the cost - it was not difficult - just google up instructions
