air vents for cooker (1 Viewer)

[Bruce]

Hi I have just installed a spinflo gas cooker with two rings and a grill I was going to put a couple of mushroom type roof vents above cooker but when I was in caravan shop asking for advice there was a chap in shop from Scottish caravan services who told me I had to calculate area of van against btus or bthus (I think it was something like that) for carbon monoxide can anybody give me some guidance please. I obviously want to do the right thing to complete my conversion........Bruce

Hmm this puzzled me a little.. Because as far as I knew a correctly burning grill /hob produces little carbon monoxide. (obviously it shouldn't be used for space heating). We have no special vents specifically for the hob or grill.. Just the general vents . We have used the hob in inclement weather in just the van with no issues... But normally have the awning attached which has a massive volume. Our co alarm has never gone off.
I'll be interested to see what's said here.

air vents

Thanks for reply. Before I went for the mushroom type vents I got advice from the company that supply gas certificate . They were happy with rear opening windows for ventilation which was needed however when I finished rear of kitchen area no access to opening these. It was a minibus so these not needed, hence mushroom vent idea. Will go back for advice and post result hopefully carbon monoxide alarm adequate, but any more views appreciated...............Bruce

Can you not fit a 12v extractor fan to use when cooking.

the people to speak to would be spinflow as in matters of gas its the manufacturers instal instructions that take precident does it ask for ventilation in those

BTUs stands for british thermal units and is used in calculating heating boiler, rad sizes, air con etc, and not really anything to do with a van conversion (maybe if you fitted air con)if you fit a small roof vent or can open a window all will be OK especially if you have a carbon monoxide alarm.

I beleive it is room width x room length x ceioling height x 20. That gives you the maximum BTU figure for your vehicle.

that sounds like a rough heat loss calc as a plumber and heating fitter we work on room volume times 5 for domestic well we did before it all went metric. times 20 sounds a bit ott even for an uninsulated van
