Not usually on inverter generators. It keeps the fuel cost low on inverter generators or something.

User RobFun (How to tag?) made a very good post back in the summertime on Inverter Vs Non-Inverters that I encourage everyone to read

I personally bought the Tru fuel one as I wanted to run on Natural gas. I've come to find out that there isn't too-too much Dirty power on the Tri-Fuel versions and haven't had any issues yet. Running my Furnace, Phone charging, TV on it.

Also, with this also using propane as well, I'll have 2 propane bottles handy.
I do the same thing.. keep my vehicles full at all times/never let them get below 3/4.

You can also put a natgas quick connect adapter to gas line outside and a couple of propane bbq tanks won't hurt either.


With the way things are going on the international stage I don't think it's unreasonable to be prepared to power ones home especially in our climate. I wouldnt want to deal with frozen plumbing (although if you're smart you would drain the lines before it got to that point but then you have no water)

What's the return policy for generators at costco? I bought a smaller one for pretty much the same price several months back, it's unused and I may return it and buy this one instead

How much does it cost? Did you do it yourself or was it done by the license electrician?

It was on Amazon for about $200. I installed myself. I am very comfortable with 110/120 volt wiring. The manufacturer also has good tutorials. (Videos) .

Only item that was a challenge was checking on the generator itself and whether or not it was bonded neutral or not (switch needs different configuration if its bonded neutral). Firman online chat confirmed what my generater had.

Last spring the tri-fuel was about $700 in-store. Should have bought then.
Propane 30lbs tanks. Unlike gasoline, propane doesn’t go bad.

220V must have, because hot water tank and heat pumps.

Good question, almost like an adapter for a BBQ that allows you to convert it from Propane to natural gas. This would be pretty interesting!

I doubt it would work.
Big difference between just lighting a gas for a BBQ and running an engine.
The engine still isn't setup to run on NG and it's not like conversion kit will it actually convert the gas.

Same here...on the fence. Still unused. Higher starting watts, propane and electric start and $200 more than the gas only model... lack of reviews on .ca but some on .com.

Correct....and not only that generaters take a lot of BTU. I would find out how much BTU the generater uses and how much capacity you have on existing lines before making any modifiactions. Even then, be sure the modifications will work for your generater. Not only do you want to ensure nothing will explode because safety features might be by-passed or overlooked, but you dont want to ruin a brand new generater if there is wrong gas flow (or other issue).

Water won't freeze if you leave it running.

Happy with my 4500W Champion inventer, a lot of power. Otherwise, I would pull the trigger, this unit has electric starter.
