Sterling hanging heater question

[smalltown]

It's been a long time coming, but finally today (of all days) when my son was at the house, and the weather was warmer than it should be this time of the year. We hung the heater, and connected the exhaust piping.

Still need to level things, etc. Next I'll complete start the last run of conduit to the heater, but I was wondering is it ok to power up the heater, without the propane connected, and what should I expect? My gut tells me it's ok, hoping the fan will come on for a while to blow out the dust that must have accumulated.

Just thinking I don't have a thermostat connected, maybe I could just jumper the thermostat wiring to get the fan going?

You can probably get it to initiate the ignition process, but it won't sense flame, so it will abort.

Seems like an air hose would be easier and do a better job of removing dust.

Yes an air hose would be better. The biggest reason is that I didn't want any surprises when the gas installer finally arrives. I thought if it was ok I would supply power to the unit, figuring if the fan operated it would spit out some dust. Just didn't want to harm my heater as it's been a long time coming.

The fan won't come on until the heat exchanger has reached a preset temperature.

Dust on the heat exchanger won't hurt a thing. Not sure what you think you could harm.

the circulating fan won't come on, but the powered exhaust fan will. As mentioned above, it will try to ignite, then sense that there is no gas and will fail, triggering a fault code that will be displayed via the LED on the main board. You can do this to test it if you want, it won't hurt anything.
