AIR INTAKE COVER 
The pedestal is equipped with an air intake cover (lo-
cated at the top front of the pedestal).  The air intake 
cover should be adjusted to the open position if outside 
combustion air is NOT provided. If outside combustion 
air is provided, adjust to the closed position (see illustra-
tion to the right). 
 

OUTSIDE AIR 
In all manufactured (mobile) homes and in many site 
built residences (subject to local code), a stove may be 
required to use outside air for combustion. A 5 ¼” (133 
mm) square outside air floor duct is available through 
your dealer. 
 
 

 
 
 

This stove can take in outside air directly through the 
base. This type installation requires a hole through the 
floor protector and the use of outside air floor duct (cata-
log # 14M67) to penetrate into the air space below the 
home. When outside air is hooked up, the Air Intake 
Cover must be adjusted to the closed position (see Air 
Intake Cover section on this page). 
 
NOTE:  Because the base sits 1” (25.4 mm) off the floor, 
the outside air floor duct can be positioned along the 
front to rear center line under the pedestal, but as close 
to the opening in the base as location permits.  The air 
duct opening must be protected from any possible ob-
struction including loose floor insulation.
