WARNING: DO NOT INSTALL lN A SLEEPING ROOM.
For installation in a mobile home, an outside source of combustion air musl be used (see "COMBUSIION AIR SUPPLY").The outside
source of combustion air must be unrestricted while the appliance is in use to prevenI room ai starvation, which causes smoke sprllage
Some spillage could also set off smoke alarms
. The slove must be grounded to the stecl chassis of lhe horne with 8 Ga. Copper wire using a serrated or star washer
to penetrate paint or protective coating to ensure grounding.
. The stove mus[ be securely fastened to the floor of the rnobiJe home using 2, I /4" lag boits that arc iong enough to
go through both a heafth pad. if used, and lhe floor of the home
. Use RTV High Temp silicone to create an effeclive vapor barrier at the location where the chimney or other component
penetrates to the exterior of lhe structure
. Refer to "VENTING" for proper exhaust confrgurations.
