BX-14 BOILERLESS OVEN
It may be necessary to delime the oven interior and be-
hind the fan guard. This is necessary for proper function-
ing of the oven. Lime will build up on the fan and heat
source leading to a less efficient oven.
1. Open the oven door. Place the oven in cool down
mode. Let the oven cool to below 140ºF (60ºC).
2. Fill the spray bottle with a non-diluted deliming agent.
Be sure to follow the MSdS or safety instructions
on your deliming agent.
3. Pump the bottle twenty times to build up pressure.
The higher the pressure, the finer the spray
4. Remove the oven racks and the rack guides on the
left side.

5. Rotate the two screws on the left side of the fan guard.
Swing the fan guard toward the front of the oven.

source and back of fan guard. Wait 10 minutes.

7. After ten minutes, use the spray hose and plenty of
water to rinse all of the deliming agent off. Repeat
steps 6 & 7 if necessary.
NOTE: If the lime scale is hard to remove or takes
multiple applications, your water filtration
system may be insufficient or your filters
may need to be changed.

time, place the oven in hot air mode to dry the interior
cavity.
