Hot surface ignition kit

[Loose Nut Buster]

I have an older LP 35k Reznor in my garage and would like to change it over from standing pilot to a hot surface ignition.
I don't use it that often and hate wasting LP with the constant on pilot, I thought about a new unit but cannot justify the cost.
Your thoughts please

Do you mean like those used in clothes dryers? I think that’s a good idea.

The parts and information you need will come from an Appliance Parts store.

Yes like on a dryer, I was thinking an HVAC supplier since I'd have to change the gas valve i believe. Haven't done much research yet, just in the thinking/considering stage currently.
Looking for the +s & -s from the forums on it.
Thanks for your thoughts on the appliance store, might work, only need 35k btu to heat it.

Honeywell sells a standing pilot to intermittent pilot retrofit kit Y8610U. Robertshaw has one as well. I'm not aware of a preassembled kit to do HSI.

Not sure if you'll ever recoup the cost given winter lasts about 6 months in the Midwest. The other 6 months you can just turn the pilot fuel off and relight when needed. With that said, I have done a few conversions on similar standing pilot equipment. I would post a link to a kit, but my current post count is too low.
If you are decent at wiring/schematics and understanding safe sequence of operation, it might be nice to have spark ignition.

Keep the pilot it’s a lot simpler for the novice to change a thermocouple than dealing with complexity of electronic ignition. The amount of gas a pilot uses during the heating season is negligible. Shut it down off season.

X2. I've installed a bunch. They work well.

Thanks on the HSI info.
My current SP is that i cannot keep it going and have replaced the thermocouple twice.
Bought it used n it worked fine 1st yr then as i explained above.
I did notice in a very small aluminum line like maybe 3/32" there is a kink going to the pilot. However i do think its always been there.

The pilot will light n have a decent flame its just that it will not stay lit and with a new thermocouple.
My thought was possibly a bad gas valve, figured if i need to replace it to go with a HSI, as far as recouping the cost...this one i bought for 35.00 n it worked fine up to now.
My thinking us that its still cheaper than a new Hot Dogg.
Recouping i compare it to going on a vacation or going fishing.
Comfort and or pleasure are hard to put a price tag on.
If i can get what i have working that'd be even better, maybe try another TCpl

A new heater is $400. I would not stick money in new ignition system, gas valve or other components with out evaluating the entire unit. My older unit fried the board
( $100) looked closer it was 15 years old, the thing was rusty, power vent fan was noisy and rusty.

Plus 11% off has to restart soon:

The pilot orifice might need cleaning. If that doesn't fix the problem then you most likely have a bad safety valve.

Safety valve meaning the main gas valve?

Generally yes. More modern thermocouple powered/pilot based devices have the safety built into the main gas valve. Older gas heaters had a separate device that the thermocouple would cut off before the gas valve.

Thanks to all for your inputs, I noticed last night that possibly my 24v transformer might not be working, was just starting to get into it and company interrupted my diagnosis.
My wife txt me that I should come in and say hi....... I did.
HI! really nice to see you this evening.
So today! My wife remembered that I said I'd take her shopping a week or so ago, well,,,,she rememinded my this morning so here i am just whistling dixie n not diagnosing.
The really good of it is that she remembered and I'm very happy about that especially at our age.
I'll keep yous posted on my discovery though. If I remember LoL

I agree. I've installed many of the intermittent spark version - and one direct ignition model - but none of the hot surface kits. So long as you reuse the OEM pilot - and leave it in the exact same position - the installs go without a hitch. It's only when you start messing around with the pilot that you get delayed ignition, big booms, flame impingement where it shouldn't, etc.

Around Tucson - when I was doing these conversions - I estimated a standing pilot would eat say about a buck a week, so $4 a month in gas. Typical winter season of 4-5 months equalled $16-$20 a year. Plus if you added in changing the thermocouple every year (good idea!) and did it yourself, double that cost. So the kit installed was costing people around $275 - that'd be about 7 years to break even. Most people went for it. Some didn't.
No big deal - I'd happily come out every fall and change the thermocouple, clean the burners, oil the fan motor, and do a CO check.

Thanks for the info on the intermittent ignition. Currently my goal is to just get the standing pilot to stay on, new tc and out as soon as I release the button. Will be checking the transformer next, worked great then this and it was after changing the tc also.
Mysteries hmmm!

You changed the thermocouple so disconnect the pilot line from gas valve and blow compressed air through it ,reconnect and check pilot. If that doesn’t work and you know the pilot is clean and sharp you need a new gas valve.
