The U44 contains an adjustable shutter cap that can alter the amount of air the burner receives. This can
greatly affect the quality of the burn, especially when converting the gas type for the unit. Follow these
steps carefully to properly set the shutter cap:
1. Remove the burner assembly from the unit (see

2. At the back of the burner (where the burner
connects to the burner orifice), there is a
single philips head screw that should be
loosened. This will allow for adjustment of
the burner cap (see Figure 11).
3. Adjust the shutter forward following the
guidelines below. These are general settings
only and the shutter may require additional
adjustment (less/more) depending on the
exact setup of the appliance:

on the back right side of the unit. To remove
the backpack and access the components,
remove the eight (8) T-20 screws around
the perimeter (see Figure 12).
Once installed, the components can be
accessed from inside the firebox. Refer
