Bernard,
PIRA makes no such claim.
Your quote, below, is a reference in the PIRA Demonstration Bibliography,
http://physicslearning.colorado.edu/Pira.asp, to Richard Sutton's classic,
1938 "Demonstration Experiments in Physics".
The entire text of Sutton's work is online and linked from the Bibliography;
by clicking the link included in this reference, you could have read his
entire (suspect) demo number H-165 here

Subject: [Phys-l] E-M radiation pressure
is sufficient for a hot object to repel smoke?
PIRA claims yes.
4B50.62 radiation and convection H-165 Put a hot metal
object in a smoke filled projection cell and the smoke will be repelled by radiation pressure. Convection will cause an upward clearing.

bc, thinks not.
