So we have a Parmco 2 burner hob going to be hooked up by a registered gas man on Tuesday... What are the required 'uncloseable' ventilation requirements I'll need to have in place to meet current regs?

My guess is as long as you have roof vents, you'll be all good.
I take it that you are either building new or replaceing ?
Either way you must bring your gas supply up to the latest standards.
Which means, copper gas line etc etc and then it's to be certed by gas plumber

yup all gaswork was done by the gas fitter, and he accepted closeable windows and a closeable roof vent as sufficient ventilation for the hob... even though my reading of the regs seems to indicate a requirement for FIXED/UNBLOCKABLE ventilation?

I 'fitted' all the appliances and drilled all the holes to speed up his task so scraped out with 3 hours labour and an $800 bill... still think i got scr3w3d but rules and regs now signed off so done and dusted!

Darwin's rules luckily not applicable as we're smart enough to always open the window and roof vent when cooking :lol: :TU

Also, for those who've been following my build, my califont now fitted in rear radiator box so 'external' and highly vented.

time to update my build thread again I guess :)

Hello. I too want to install a Parmco 2 burner gas hob ($260 from Bunnings) in a 3.6x1.8 mtr cargo van. It will be the only gas thing in the van (unless I've eaten lots of baked beans!!! LOL). I've talked to a gas fitter who sounds knowledgeable about Camper gas regulations. However I would like to query his requirements for vents in the body of the van ie not the gas locker. He recons I will need a permanently open vent with a 6mm gap up high so, OK, I've got that covered with a 400x400 hatch which the manufacture says is permanently open. However he wants a vent on the lowest part of the van (which in my case will be the floor-no step) of either 400x150 mm or 600x100mm. To me thats huge and what about dust, insects, road spray (and probably road kill!!) coming in...plus I think the draft coming in must surely negate the exit of spilled gas. Is he correct??? And if so will be grateful for any suggestions of where I can put it?? Also do I just use a grill type?
Thanks Karyn

I have noticed that most ( if not all ) newer motorhomes do have a permanent vent grill installed in the lower part of the door. I guess that is to meet this requirement. My older van does not have this lower grill vent. The two roof vents have vent slots that remain open when the vent is "closed".

there must be a vent at the highest point (roof) and the lowest point (usually bottom of door or in the step well) or so I am led to believe.

venting on doors should be at lowest point and of free flowing

From the regs

7.3 VENTILATION OPENINGS—CARAVANS AND BOATS
7.3.1 Minimum free area
The free area of the total permanent ventilation for any space in which a gas appliance is
installed shall be at least 4000 mm2 or the value obtained from the formula below,
whichever is the greater:
V = (610 × U) + (650 × P)
where
V = minimum free area, in mm2
U = input rating for all gas appliances, (other than room sealed) in the space,
including cookers, in MJ/h, refer to rating plate
P = number of sleeping spaces in the caravan or boat

I'm not a gasfitter and I'm not sure if this is the total for top and bottom, or total for each.
I'm planning on putting an AEG hob in mine and the calc works out about 11000 sq mm (or about 150x75) so I am guessing it is total for each.

And for a motorhome you cannot put the vent in the back wall.
