The following steps are required for installation of the Winslow™ 
PI40 insert in mobile homes. See Figure 12.
1.  Connecting the Winslow PI40 insert to outside combustion 
air is optional, except in mobile home installations and when 
required by local building codes. The insert’s air intake will 
accept 2” ID pipe to accommodate outside air installations. 
The air intake on the exterior  of the home should always 
be located  substantially below  the  flue termination  and 
terminate with a cover to keep out weather and pests.
2. The insert must  be fastened to the hearth/floor using lag 
screws. The screws can be inserted through  the holes in 
the base located  behind the  side doors.  If the  hearth is 
concrete or masonry, use  proper lag bolts  and methods 
designed for anchoring to masonry or concrete.
3. The insert  must be grounded with  a #8 or  larger copper 
wire.
WARNING:  DO NOT INSTALL THIS INSERT IN A SLEEP-ING ROOM IN A MANUFACTURED HOME.CAUTION:    THE  STRUCTURAL INTEGRITY  OF  THE MANUFACTURED HOME  FLOOR, WALL,  AND  CEIL-ING/ROOF MUST BE MAINTAINED.CONTROL

*   This black surround kit positions the insert 3” forward so that it will allow the insert to fit 
into a fireplace with a narrower width in the front (32” min.).  Note: No trim kits are avail-
able for this kit at this time.  See instruction sheet P/N 506033-05 for more information.
