Warning
Fill the trap with water before initially firing the boiler to prevent exhaust fumes from entering the
room. Never operate the boiler unless the trap is filled with water. Failure to comply will result in
severe personal injury or death.
3.7 Installing a condensate neutralizer
If discharging condensate into building drain piping materials that are subject to corrosion, use a
neutralization package.
Warning
After installing a condensate neutralization package, the pH of the condensate discharge must be
measured on a regular schedule to ensure the neutralizing agent is active and effective.
