OUTSIDE COMBUSTION AIR
WARNING
Fireplaces in manufactured homes must be supplied with outside combustion air.
These fireplaces are provided with model AK6A combustion air kit (for floor installation only) to supply outside combustion air to the fireplace.
If outside wall installation or ceiling/soffit installation is preferred, pur- chase model AK6 combustion air kit from fireplace dealer. See Figure 10, page 12.
PRECAUTION AND RECOMMENDATIONS
1.Avoid extremely long runs and numerous turns in the flex duct leading from the fireplace to the air inlet assembly. These conditions will increase the resistance to the free flow of air through the flex duct.
2.Locate air inlet assembly where it will not be blocked or restricted in any manner.
CAUTION
Maintain the structural integrity of the manufactured home floor, wall, and ceiling/ roof.
3.Never mount the combustion air inlet assembly in a garage or storage area where combustible fumes such as gasoline might be drawn into the fireplace. Do not take combustion air from any area where combustible liquids or gases are stored.
4.Carefully cut holes for the installation of the combustion air kit. You must maintain the structural integrity of the home.
