The advice from Dometic is just default, ie no flames in a confined space. This is advice that should be given to anybody who might ask the question on a forum. So really the op just needs to make his own mind up.
I have a 1205GC which I've run on gas in the side awning of my Icarus 1000. It doesnt use a lot of gas on the low setting - a canister will last about a day and a half. I wouldn't feel comfortable with it in the main part of the tent but it wouldn't warm up too much if you turned it off at night would it?
what about using it in a small beach shelter next to your tent? with the opening facing towards your tent, we used 2 fishing shelters set up as a kitchen tent, as they where just tall enough for me to stand in but plenty of ventilation

Carbon Monoxide, BBQ and Fire Safety Advice
In recent years there has been a spate of tragic deaths of campers and caravanners, from carbon monoxide poisoning from barbecues. Please help our campaign to try and stop this happening again
BBQs and Carbon Monoxide - Important Please Read
Please note, although you may be tempted to put your barbeque in your tent, or tent porch, either during or after use, to keep you warm, DONT! It may kill you, and very quickly.
Carbon monoxide fumes from BBQs are invisible, odourless, and lethal. Even if you think it's safe, and the flames have died down, don't do it. The smouldering coals may be warm, but they will kill you. Even with the tent doors open. Even just in the porch. Please don't do it!
You can download a warning poster here alerting of the dangers of carbon monoxide - why not laminate it and put it in your tent window, or maybe ask the next site you visit to put it up in their reception window. ( poster is a PDF file )

General Information regarding Carbon Monoxide
The burning of all fossil fuels produces carbon monoxide (CO) and there have been deaths and serious injuries from CO poisoning in tents and caravans.
Do not use stoves or disposable barbecues (for cooking or warmth) in an enclosed space with poor ventilation.
Don't use gas fridges or heaters inside tents.
Caravanners should have gas-powered appliances serviced annually.
Also don't be lulled into a safe sense of security just by having a carbon monoxide detector in your tent or awning. They are designed to be used in buildings, and sometimes caravans and motorhomes, but won't necessarily be fully effective in a tent or awing. Take one of course, but please don't rely solely on it and ignore the other precautions just because you have one.
Please remember that CO detectors have a limited life - usually five to seven years, yours should have a sticker on it to let you know when it needs replacing. If you don't know how old yours is, then it's safer to buy a new one, they are relatively cheap and readily available.
General Fire Advice from North Wales Fire and Rescue Service
North Wales Fire and Rescue Service is issuing safety advice to caravanners and campers following a tragic fire on a Barmouth campsite in June 2011. The fire in a caravan on Sunnysands Caravan Park, Talybont, near Barmouth, occurred in the early hours of Saturday morning (June 11), and claimed the lives of a 58 year old man and his 26 year old son.
North Wales Fire and Rescue Service is advising those planning a break in a caravan or tent to keep the advice below in mind:
- Ensure tents or caravans are kept at least six metres apart.
- Find out what the fire-fighting arrangements are on the campsite and where the nearest telephone is.
- Fit an optical smoke alarm in your caravan
- Keep a torch handy for emergencies. Do not use a candle.
- Do not leave children alone in a caravan.
- Keep matches and lighters out of the reach of children.
- Do not overload electric sockets or extension leads if you have access to a power supply and make sure electrical appliances are working correctly
- Keep flammable liquids and gas cylinders away from tents.
- Do not cook inside your tent.
- Be prepared to cut your way out of your tent in the event of a fire.
- If your clothing catches fire, STOP, DROP AND ROLL.
- Oil burning appliances should not be used in or around tents.
