Page 31: Application
When a condensate pump is required, select a pump which is approved for condensing furnace applications. To avoid conden- sate spillage, select a pump with an overflow switch. Furnace condensate is mildly acidic, typically in the pH range of 3.2 to 4.5. Due to corrosive nature of this condensate, a condensate pH neutralizing filter may be desired. -
