Furnace and Water Heater is same box???

[shaymcquaid]

Hello and thanks for looking:

I’m thinking of putting my Big RV furnace is the same box/compartment as my big RV water heater.

Is this bad practice?
I do know that the appliances “purge themselves” before a light cycle....but.

Me no like go boom!

Thanks,
Shay

They are both vented to the outside?

Yes they are...

Do you have brand and models?

Initial opinion is that it’s fine. An Installation manual check is a good idea though.

I don’t think what you have on ignition is a purge. It’s a prime. It’s an initial jet of propane that is ignited by a pezio igniter.
