yeah, it was -3 here last night.
The water temp on the lake is 36 at 3 feet depth (bottom of the thru hull transducer).

Woke up kind of cooler than usual - felt the heat/ac vents at the house and lukewarm air coming out.

Checked the gas furnace and the flame wont stay lit for more than 25 seconds then off for 20... High efficiency furnace - draft motor - pvc flue venting. When the flame is "on" it looks and sounds perfect. Opened up the bottom of the return air duct box to make sure adequate airflow was getting thru unit to rule out anything there - no change.

House is "fine" - around 70 degrees, and the temps look to be climbing back upwards after today, but wondering what the issue may be.

There is a "draft" indicator that measures the vacuum the draft motor is pulling. There is an overheat sensor near the draft motor that cuts the flame if the combustion air is "too hot" when it reaches the draft motor (like inadequate thruflow of household air would cause). There is a backflash switch to kill the flame if the flame pops back out of the burner. Not sure where to look...

Ideas?

Wardy, do you live right on the Gulf. Boating report on Bay News 9 said 7-9' yesterday.

Gator - Yeah i'm on the Gulf but Three Rookers Bar is kind of a break water for me. But, yes, it was rough. About 2's on the inside and I could see big water breaking at Rookers. Flat today but cold as hell. Wardey

YOU BUNCH OF FRIGGIN BABIES.

On Tuesday it was -25C here in Barrie (just north of Toronto)

That is -13F for you imperial folks. Going sledding this weekend. The old storm is leaned out and should be running really good tomorrow.

Let's see -13F at 60mph is about -55F NOW THAT IS COLD.

Mighty cold here as well. It got down to 32 here last night, and it'll do the same tonight. We did warm up to about 50 by now (9:45).
I'm not so worried about my cold fingers.. it's my cold 502 Mags..
They're not winterized, or drained...
It only gets below freezing for about two hours at night..
I really don't think I'll have any trouble. But, I just moved here, and am accostomed to living up north where our boats are always winterized...
Anyone have any feedback???

These are extraordinary conditions. Our weather reporter said that this was the coldest low in like 12 years. It's not too often we need to worry about winterizing. Down by where you live, it's even less of a concern than here.

At 2 hours a night, you will be fine.

Wild,
Yes we are!

We had about 6 hours below freezing.

There goes our snook population that has been growing steadily the last several years.

Very good site for HVAC-related questions. Someone on there can probably help you find the problem.

Looks like you guys down south of us were actually a little colder than it was up here in Louisville. Official temp didn't go below zero here, but it was colder at my house in the "boonies". Must be the extra snow that you have on the ground.

Good luck and stay warm.
