2.1 System Description

The Cub 400 and Cub 700 heaters are indirect-fired air heaters. The

Cub 400 and 700 have stainless steel fireboxes and heat exchangers.

They run on three fuel options: diesel, natural gas (NG), or LP. The fuel

is consumed in a closed combustion chamber. The exhaust gases are

vented outdoors through a vent pipe. The clean, dry hot air is blown or

ciculated in the space by a centrifugal blower. The blower assembly is

protected by a guard fitted on the air inlet.

Cub 400 and Cub 700 heaters are meant to heat air on construction

sites and in other rugged applications. Do not use the Cub 400 or Cub

700 for any other purpose.
