Ventilation for a Wave 6 in a Bus

[Karin]

I ordered this awhile back, have all the parts for it including the legs, but haven't hooked it up yet, since a small electric space heater has sufficed thus far. However, cold weather is on its way.

The manual says "It is good practice to have at least two openings, one high and one low." The instructions for ventilation in an RV consist of opening the roof vent by 1/4 to 1/2," and cracking the window by the same measure at the opposite end of the RV from the roof vent.

The bus has no roof vent. I could crack a window near the heater, and possibly one at the opposite end and side of the bus.

There are presently a lot of cracks where air can get in, but I'm getting ready to duct tape a layer of Reflectix on top of the sheathing I've placed against the windows, allowing for appropriate airspace between the sheathing and Reflectix. Thus, it will be a relatively tight seal.

Recommendations, advice?

Thanks!

Since warm air rises, it's fairly obvious that the high vent is intended to be the exhaust, and the other opening will therefore be the cold air intake.

Were you going to set the wave on the floor? If so, I wood think that a floor vent right under it would maximize the oxygen to it, while it would also heat the incoming cold air, thus reducing cold drafts.

Over in the DISCUSSIONS THAT DON'T FIT IN OTHER AREAS sub forum, there is a thread about ventilation in which HighDesertRanger has posted some pictues of inexpensive vents from the boating world that seal tightly when not in use, that might be perfect for that.

My Wave 6 instructions read that, for 'home use' [rather than RV use]:

'Open two 8" wide windows 1-1/2" at opposite sides. If possible, open one window at the top and one at the bottom". Total min. air space 24 sq. in.

So it would seem that if you open windows at opposite sides of your bus you will be OK. Personally, I open mine a little more than the minimum. And, of course, you should have a CO detector.

I can't really create the ventilation in the ceiling or on the floor, as it isn't my bus, so I'll go with two windows and a wider than recommended opening. Thanks for the suggestion of the C0 detector, I completely forgot about that.

karin, you've got it figured out! The high and low is ideal but not absolutely essential. As long as you have a minimum of 24 inches of ventilation it will be fine. Adding a little extra and separated for cross-flow is a very good precaution.

I missed the reference to twenty four square inches, thanks for pointing that out. I'd better do a better job of reading the instructions - but then I've just perused them online - I haven't even opened the box for the heater!!

Thanks, Bob
