Before we start yes it is a gas question but seeing that I`m posting in the arms away from the public view and I`ve been around for several years and met a few of you in person I`m hoping that you will believe me when I say that the LPG gas man in the marina is doing the work not me.

Have an LPG cooker on the boat and wanted to place a LPG hob over it however reading through the instructions I saw "An oven must have forced ventilation to install a hob above it". The oven has fan for cooking and is vented out the back, is this what it means?

Thanks.
 
Fan to supply fresh air eg you could use an inline extract fan and just turn it round

don’t suppose it says the needs normally in m3/h

Thanks for the info and trusting me Shaun, you`ve just saved me money because the guy the marina owner forces me to use would want paying regardless.
Can`t see anything about it in the instructions but at least I can warn the guy to bring one with him and hopefully he will know what is needed. All this ventilation stuff for the BSS is hard work and based on square meterage of boats.

Anybody know of 12v fans I could use?

Chances are the fan will have to be interlocked with the appliance.
Eg: Fan not operating - appliance won't start.

There may also be a requirement of the amount of ventilation needed.
LPG is heavier than air so it sinks into low areas.
It also has a very low LEL, 2.1% - meaning it only needs to have that percentage of gas in air to ignite.

You are spot on re ventilation requirements oz and they are very strict on boats, as an example there are 4 10"x 6" vents in both sides, every door has vents both high and low and I have to get a BSC every 4yrs along with a hull survey for the insurance.
 
Glad to help RPM.

- only in 'The Arms' would I have divulged this info for your benefit !!!!!

Look into the full requirements.
Gas faults or CO on boats often doesn't end well

All the help is appreciated, I placed it in the arms away from the public, even then I wasn`t sure that people would respond tbh but hoped that being around for some time would help.

I`ve emailed the gas guy with make & model of both units, the amount of room we have to work within and things as I see them as he is reknown for being a grumpy git who finds fault and asks for his money regardless, I wouldn`t use him by choice but the marina owner insists on who can enter the marina and takes a % of the costs on top!

Being on boat forums I often hear about deaths from lack of ventilation regarding LPG cookers, wood burning stoves and diesel warm air heaters all being badly installed.
