[Lab] Laser Update

Hi Lab Awesome People,

To move venting forward,
Do you have permission from the landowner? Typically installation would be
through a wall. Google map shows the building with a thick stone exterior.
A mason would take a few hours to properly install a louver, which would be

Do you have a budget for this installation? Exceedingly rough,
$600 - Mech Eng to verify building airflow
$600 - Mason, wall penetration
$600 - HVAC installer's time
$250 - painted louver (not including HVAC installer markup)
$150 - snap lock pipe, reducers, elbows, screws (not including HVAC
installer markup)

Pieces required are available from HVAC suppliers in Ottawa;
EH Price - Louvers
Noble Trade (bought Don Park) - Piping, elbows,  screws

For the very near term it could be vented out a window. It doesn't look as
nice, however it may become the only option if the landowner does not
approve cutting the stone.

I can help install the inside HVAC, and advise wall penetration but not
complete it. If anyone is interested in the fan I picked up, I would love
to drop it off.
