Never A Compromise
For Quality or Safety

The Atmospheric Burner System, control system and the entire boil-er are furnished so that it is simple to operate by regular personnel. Simplicity is a decided advantage as there are no expensive blowers, complicated controls, or burner adjustments, as is necessary on many boilers.

Parker Boiler Certifications
All Parker Boiler Steam Boilers are manufactured in accordance with the ASME Power & Heating Boiler Codes and registered with the National Board of Boiler and Pressure Vessel Inspectors. The standard natural gas fired model is furnished as an Under-writers’ Laboratories, Inc. Listed Gas Fired Boiler Assembly and displays their symbol on the nameplate. Outdoor, propane and Low NOx models are ETL listed. Canadian models are C-ETL List-ed Industrial and Commercial Gas Fired Packaged Boilers certified to CAN/CGA 1-3.1 and UL 795.

Easily Repaired
Any steam boiler will likely require retubing sooner or later, depending on care and operating conditions. Recognizing this, special design consideration was given to this concern. Parker Steam Boiler Tubing is constructed in several individual sections, each connected to the boiler drum and lower Headers by pipe unions. To replace any section of tubing, it is only necessary to undo the union and remove that section of tubing. It’s possible to temporarily operate the boiler with a tube section completely removed by replacing the unions with pipe caps. All sections of tubing are interchangeable and so low in cost that many owners purchase an extra section of tubing to have on hand to meet any emergency requirement. Furthermore, the tubing sections on most models can be turned over after several years of operation adding many additional years of service.
