Fuel Burning, Heat Producing Appliances:
All fuel-burning, heat producing appliances, except ranges and ovens, used in manufactured homes draw fresh combustion air from the outside of the home. This includes such appliances as water heaters, fireplaces, gas refrigeration devices, gas furnaces, and gas clothes dryers. The manufactured home's sealed combustion system has two advantages over conventional systems:
1. It is safer; combustion gasses are not released into the interior of your home.
2. It is more economical; inside air, which has been heated or cooled to the desired temperature, is not lost through the exhaust duct or chimney.
CAUTION: If replacement of a fuel burning (gas or oil) heat producing appliance becomes necessary, the replacement must be listed or labeled for the use in manufactured homes.
