Monthly Maintenance Program

Our MAXIMUM COVERAGE offers the best protection against system failure and downtime. It is performed in addition to our Quarterly & Annual Maintenance Programs. On a monthly basis, we will inspect the boiler equipment for irregularities and fine-tune the fuel-to-air combustion curve(s) to maximize burner combustion efficiency. A significant benefit of this program is proactive boiler operational awareness to optimize system performance and minimize operational costs.
As a part of this plan, preventive maintenance will be performed every month. The inspections and tests listed below will be completed eight (8) times a year in addition to the one (1) Annual Maintenance visit and three (3) Quarterly Maintenance visits.
On-site maintenance guidelines are subject to customer needs, local jurisdictional authority requirements and may vary at the local level. Please review our proposal for local details.

Quarterly Maintenance Program

Our PRINCIPAL COVERAGE includes all of the inspections and tests in our Annual Maintenance Program as well as three (3) additional on-site visits. Your boiler system will receive the necessary technical assessments, testing and fine-tuning of the fuel-to-air combustion curve(s) to maximize burner combustion efficiency. This quarterly program will help extend equipment life. As a part of this plan, preventive maintenance will be performed on a quarterly basis. The inspections and tests listed below will be completed three (3) times a year in addition to the one (1) Annual Maintenance visit.
On-site maintenance guidelines are subject to customer needs, local jurisdictional authority requirements and may vary at the local level. Please review our proposal for local details.

Annual Maintenance Program

This CORE COVERAGE provides professional technical resources to improve the safety, reliability, and efficiency of your boiler system. We will conduct the necessary assessments, tests and maintenance to fully support your boiler’s optimum operation. At the end of the required Annual Inspection, the boiler will be closed and fitted with new Genuine Cleaver-Brooks gaskets. You can be assured that we will replace degraded and/or failed parts with Genuine Cleaver-Brooks Parts to ensure maximum system performance. All findings will be documented and reviewed with you.

Boiler Room Maintenance Guide and Logs
Instrument readings, as appropriate to specific boiler systems, need to be taken daily for low-pressure heating boilers and at least once per eight-hour shift for high-pressure boilers. These readings must be recorded in the boiler log.
It is very important that the boiler log is kept in a consistent format in order for trends to be perceived and followed with preventive action. Standard forms are available for this purpose below. However, the log may be more useful if the log form is customized for a particular installation.
