## Questions & Answers

**Q: Putting a 16,000btu propane range in home. Want to have tanks I can handle. Will this work with two 40pound bottles?**
A: Yes it can. Open both bottles and it will pull from one until empty and then switch to the other one when needed. I can run my stove, camper heater and hot water heater at the same time from my 2 20lb bottles.

**Q: I bought this to use with a heater buddy in a small cabin.  While trying to find a fitting or connecting hose I was told the two are not compatible.**
A: I don’t know about the heater buddy connection but the unit should hook to tanks just fine

**Q: Will this work for a 55000 btu propane wall furnace?**
A: Yes
But it’s made with two outlets. You will have to plug one as needed. Or by a single regulator.

**Q: Is this unit compatible with Gaspro Type 1 gauge?**
A: If the gauge is designed for propane then yes.
