Suburban Furnace ID

[Alwhisman]

I'm trying to ID my furnace. I've looked for a tag but cant find it. I'm going to replace it, but rather not pull it out until I'm ready with the new one.

Tried to use it a couple of days ago, and had two "delayed" ignition poofs....enough for me. Going to upgrade so I can get out of the pilot light era.

Thanks,

Al

I'd not touch the gas lines; find a pro.

I had to remove mine to find out what model it was.. the sticker was on the blower housing.

lol, thats what I was afraid of! I've pretty much decided on the NT 34, just wanted to know what I have now. Hate to go too big. Lowest temps I run into is 25-30, so it would do fine.

Thanks,

Our 31-footer has an NT 32, IIRC. 34 should be plenty for the 7.3 metre. That's only 24 feet. I'd figure you could easily go lower...

Our 31 footer has a NT-30SP. Once I get it working again, I will know if it's enough.. but I am sure it will be. Also, at least on ours, it was VERY easy to remove. Fuel line, 1 electrical connection, the ducts, and then the screw through the intake, slid it out of the compartment.

I put an NT 30 in my 25' Tradewind and it does the job. I know others have also. I don't know if there is such a thing as too big a furnace or not.

I have a SF-20 (same as NT but different form factor) and it did a good job keeping my 24' Tradewind nice and warm in 25 deg. weather last weekend.

I think somewhere in the past we decided 1000 btu/foot was a good rule of thumb, so that's what I used.

Thanks folks! I like the lower size unit, saves me amps! lol I really appreciate the input. I only use the furnace when I boondock, 3 or 4 times a year

I've designed for houses ALOT, but don't have a clue for a formula for RV's, a lot of different factors, etc.....34 seems excessive for a 24 footer, but I'd rather have more than have it inadequate. I know in homes over sized will be very inefficient, but as Lumatic says, I don't think it would hurt anything.
