Raypack Question


May 30, 2017

Hi there,

We are looking to purchase a Raypack 336 online and noticed there are two different models, one for elevation over 2k and one for under. We are right at the 2k mark. Is there a reason we should go with one over the other? We were thinking of getting the 2k and over model since we're right on the edge. What's the difference?

Gas orifices are typically adjusted for high altitude for correct fuel/air mixture. Do you know if your home gas heater is a high altitude model? I think for this case I'd call Raypack and get their advice.
