Stacking Option
The Commander make-up air heaters can be stacked 3 units
high for storage. See Fig. 1 for stacking detail.
• Heaters must be stacked on a solid, stable, level surface.
• Never stack on dirt or other soft surfaces.
• Never try to move stacked heaters.
• Remove gas supply hose and regulator prior to stacking.
• Never stack more than 3 heaters high.
• Do not operate the heaters while they are stacked together.
Stacking Base Kit
500-133994A, Commander 500
500-133994B, Commander 1000
When stacking the heaters two or three high, L.B. White
highly recommends the use of the stacking base kit. This
will remove the weight of the heaters from the wheels of
the bottom heater, preventing any flat spotting on
the wheels.
