Steps
Set the heater on flat, firm ground outside the tent, at least a metre from the fabric and clear of anything that could fall onto it.
Run only the hot air duct inside, through a zip or a duct port. Seal the gap around it so cold air and fumes cannot creep back in.
Point the exhaust downwind and away from the tent. Keep it clear of snow and well away from the heater's air intake.
Clip a carbon monoxide alarm inside the sleeping area and test it before you start the heater.
Fill the tank with winter-grade diesel, connect a charged 12V battery, prime the fuel line, then start on the lowest setting.
Crack a low vent and a high vent so damp air can escape. Condensation builds when warm moist air meets cold fabric.
Run the heater steadily overnight on low rather than letting it cycle on and off, so the tent stays dry at 3 a.m.
Use the shutdown cycle to cool the unit before switching off, and never refuel a hot heater.
In deep cold, add anti-gel to the fuel or keep the can off the frozen ground, because diesel turns waxy and stops flowing.
Tips and common mistakes
The 8 kW on the box is a peak figure, so do not size your whole setup on the sticker alone.
Diesel starts to gel around -10C, so use a winter blend or an anti-gel additive in freezing weather.
Keep the fuel tank outside the tent too, and refuel only after the heater has cooled down.
A dry tent feels warmer, so venting moisture out matters as much as adding heat.
Questions
Can I put the diesel heater inside the tent?
No. Run it outside and bring only the hot air duct in. The exhaust contains carbon monoxide, which can kill in a sealed tent.
Why is water running down the inside walls?
That is condensation. Burning fuel and your own breath add moisture to the air, so keep a low and a high vent cracked and run the heater steadily.
How much diesel does a night use?
On low, a small unit sips fuel, so a 5 litre tank usually covers a night or two. Check the rated consumption for your own heater.
