H. Mobile Home Installation
You must use a Harman® Outside Air Kit for installation in
a mobile home.
1. An outside air inlet must be provided for the combustion
air and must remain clear of leaves, debris, ice and/or
snow. It must be unrestricted while the appliance is in
use to prevent room air starvation which causes smoke
spillage. Smoke spillage can also set off smoke alarms.
2. The combustion air duct system must be made of metal.
It must permit zero clearance to combustible construction
and prevent material from dropping into the inlet or into
the area beneath the dwelling and contain a rodent
screen.
3. The appliance must be secured to the mobile home
structure by bolting it to the floor (using lag bolts). Use the
same holes that secured the appliance to the shipping
pallet.
4. The appliance must be grounded with #8 solid copper
grounding wire or equivalent, terminated at each end
with an NEC approved grounding device.
5. Refer to “Clearances to Combustibles and Floor
Protection” section of this manual for listings to
combustibles.
6. Use silicone to create an effective vapor barrier at
the location where the chimney or other component
penetrates to the exterior of the structure.

installing the vent system for use in a mobile home.
