Ensure Sufficient Venting in Heater Room

      To dissipate heat lost through the heater casing and to provide combustion air, the heater room should be adequately vented. Generally the heater controls are in the heater room and they will have a longer life the lower the ambient temperature. Often the heater is close to a process that produces a lot of dust, and in this case it is better to duct the combustion air from a clean area or from outside.
