General Requirements
1. Safe operation of any gravity vented heating appliance requires a proper air make-up
system to prevent the heater exhaust gases from being drawn into the building. These
gases could cause death, serious injury, and/or property damage. Exhaust fans, paint
booths may cause draft problems.
2. Never vent this heater into another heating appliances chimney. Never vent into “Class B”
chimney. Gas heaters use “Class B” chimney, it is rated for a much lower temperature than
is required for your waste oil furnace. This heater must have its own separate “Class A”
chimney.
3. Inspect and maintain the chimney on an annual basis.
