Heating setup when on generator when cold weather

Turn on the Oasis burner switch, and set thermostat zones to furnace. If you have generator auto-start, then enable it with voltage set to 11.9 volts

Hopefully you have plenty of diesel fuel.

You probably have a large battery bank like our DutchStar, so you will be fine.

If you have Oasis engine pre-heat, use it 1 hour before needing to start main engine to drive somewhere. If you donít, you can enable your engine block heater and start the generator (block heater works slower, so start it at least 4 hours prior to engine start)

I just spent five days dry camping in the conditions you mentioned. I turned the furnace on and left the burner on with the generator set to auto start. I started with a full tank of fuel. In those five days the burner ran almost constantly and, the generator would start once a day and run for several hours to charge the batteries. I used 37 gallons of fuel in those five days.

Fuel is going to be what determines how long you can do this. The generator will not run below 1/4 tank.

Appreciated

Tried as described but still "on joy".... Oasis burner is definitely on but still only getting heat from 1/2 bath and rear bath. SliverLeaf is showing blue flame icon on the bath room but no fan symbol nor is it shifting to the other zones. Plenty of fuel on board and tried calling Newmar Service Center only to get referred to both SilverLeaf and Oasis for help.

Any additional potential steps that I'm missing

All the slides are in (if that has an impact). Until replacement part is installed on the radiator fan clutch, I'm stuck and cold.

Thanks to all for helping this CRS graduate

Thermostat set to furnace on zones 1 & 3 with zone two off. That is my Dutch Star setup. Turn on diesel burner. All zones should then provide heat. Your coach may have Silverleaf and different zone options. Turn on heat in half bath and the hydronic heat switch to high or low up on the row of dash switches. If you still do not get heat in the kitchen and front dash area you may have a loop one pump failure, a loop one check valve that is stuck closed or an electrical problem. Check all GFI’s . These coaches are well insulated and the Oasis will always keep you toasty warm when everything is setup correctly.

[Moderator Edit]

With 3/4 tank I would guess you have about 10 days before needing to refuel.

The blue flame is all you will get on the Silverleaf display when Oasis heat is running for the zone. The fan symbol is for the heat pump blower motor which does not factor in here.

So you donít have heat from the front zone (under dash and kitchen) or in the bedroom. On each of these zones (living room and bedroom) is the heat turned on and is the temperature set at least a few degrees above the current temperature display for that zone? Is there a blue flame for these zones?

If you are not living in the RV, why not just drain and winterize the rig and then no more worries.
