Fuel-fired furnaces should always be operated under a slight pressure since this tends to even out the flow of gases inside the furnace and prevents ingress of cold air round the doors and other openings. A reasonable pressure to aim for is about 2.5 Pa (0.01 in w.g.) and this should be measured at the hearth level to avoid the buoyancy effect.
