7-1: Testing the system before gas connection

Note: No gas is needed to test the system
The R320ST*/R420ST* Control and Power Vent System can be
safely tested prior to finish framing the Fireplace. This test can be
done quickly and efficiently to ensure all systems function according
to the design specifications.
The fireplace should be installed on the rough-in frame, with the
Power Vent Module and the Vent run connected.
The control panel is supplied with a power cord plug in.

Plug it into aN extension cord or any other 110 Volt power supply.

If the red LED is illuminated (beside the fuse) you have power

to the panel.
If no LED, check fuse and replace with equally rated fuse.

Turn the wall switch to the on position.

Wall switch and combustion air LED light up immediately.

approximately 30 seconds later when the power vent reaches factory
set speed. The flue gas switch LED will light up approximately 1
minute after flue gas LED is lit and the gas valve will turn on. You
can hear a clicking sound and the Hot Surface Ignitor will glow red.
This confirms the control system operation. Note: If the flue gas LED
does not light up after 1 minute, slowly increase the power vent speed
until the LED turns on. Speed controller located inside the control
box, see Figure1Sec7.
