Operating Instructions
FireStar Combustion Controller
Refer to the FireStar Operator's Manual provided with your outdoor furnace
for information about the controller.
Firebox Door Opening Procedure
This firebox door opening procedure should be followed whenever the firebox door is
opened regardless of coal type. Even if the outdoor furnace has been shut down for an
extended period, there can be a concentration of combustible gases present. Following
these instructions reduces the possibility of a flashback.
1.
Make sure the outdoor furnace has power and is turned on.
2.
Press the Purge button.
NOTE: Press the Purge button even if the combustion fan is running.
3.
Listen to make sure the combustion fan has started and is running.
4.
The purge LED and over air LED will illuminate violet. The under
air LED will illuminate violet 30 seconds into the purge cycle. After
approximately one minute, once the purge cycle is complete, these three
LEDs will turn green.
5.
If there is no smoke, or only small wisps of smoke coming from the
chimney, proceed to the next step. If there are large amounts of smoke,
wait until it has subsided before continuing.
6.
Standing off to the side away from the firebox door opening, gradually
open the firebox door, stopping when the firebox door handle safety recess
catches the latch roller. Wait for a minimum of 15 seconds.
NOTE: During this time you should hear the combustion fan stop.
7.
If large amounts of smoke start billowing out from around the firebox
door, close the firebox door immediately and wait at least 5 minutes before
repeating steps 2 through 6.
8.
If there is no smoke, or just small wisps, carefully open the firebox door all
the way while standing to the side.
Always follow these steps, including standing off to the side of the firebox door, when
opening the firebox door. Combustible gases could flashback.
