I've got a propane heater not igniting and I would sorely appreciate any advice. My troubleshooting, with only one concern, suggests that it should ignite!
I have a Hayward H100ID Spa/Pool Heater, Propane. It’s hooked up to a propane canister (not tank) via a 100,000 btu regulator. I’ve taken it apart and verified that the orifices are clean - the whole machine looks very clean (I bought it used, but minimally).
When the thermostat calls for heat, the blower starts up. Gas output pressure at the valve is ~2†WC. Input pressure, however, is higher than called for - maybe 15-20� This is issue #1; I'm not clear about pressure off this canister.
The heater does not ignite. I’ve pulled the ignitor, and verified that it’s sparking like mad and has no carbon buildup. It’s clean and white, with about a ⅜†gap. The gas valve audibly clicks, and I can smell gas. (Issue #2)
My questions:
1: Why does my 100kbtu regulator (brand new) provide so much pressure? Is this the right amount, and if not, how does that work? The heater wants 100kbtu in, so a 100kbtu regulator seems correct. I'm comfortable with most of the rest, but I know little about propane cans (I'll be replacing that small can with something larger later on.)
2: In any case, given the output pressure is correct, am I justified in thinking that there is some other problem preventing ignition?
3: What could that other problem be? What else could I check?
Thanks a million y'all;
Joshua
