Does this furnace create a negative flow in my mobile home

When installed properly, with a dedicated fresh air intake for combustion and a dedicated exhaust pipe to discharge flue gases, the MG2R furnace is does not create a negative pressure in the home. The furnace return and supply air is self-contained to the interior of the home and is circulated through the duct work so this will not create a negative pressure in the home either.If you have any further questions please feel free to give us a call! Thanks.
