25 PDVC shut it self off.

Oh, and this statment in the manual on page 12 is incorrect too... ! I can change the Blower Speed to any number from 0 (off) - 9 with any heat range from 1 - 9.

*NOTE: Blower Speed will automatically be adjusted to the desired Heat Range that you select.

Now, if they ment the exhaust blower with it's speed, they are not making this clear here in this statement.

Uh, genius....that is referring to the COMBUSTION blower.

Ah, Glad we got that one cleared up then.

Now-Now children, play nice.
and remember, there is nothing harder to open than a clenched mind.
