test ports are located next to the center
tray leg opposite from the pilot. (Fig. #99)
3.
Thread the extension test fi tting into the
open port.(Fig. #100)
4.
Attach a pressure gauge onto the fi tting
and rest the gauge on secondary fl oor
where it will be visible with the doors
closed and unit running.
5.
When testing is complete shut off the
gas, remove the fi tting and replace the
plug. Thread sealant will be required to
