Do you own a boiler?

In November or 2006, the State of Michigan instituted new rules regarding the installation, maintenance and testing of control and safety devices on automatically fired boilers used in commercial and industrial settings.

State of Michigan rule R408.4027 (rule 27) of the boiler code, adopts the American Society of Mechanical Engineers (ASME) standard CSD-1.  CSD-1 requires boiler owners to establish maintenance and test schedules for their boilers.  Rule 27 specifically requires that controls and safety devices be tested annually by an individual in possession of a mechanical license with a category 5 or 6 authorization.

What does all of that mean? 

If your building has a boiler, it needs to be tested annually by a state licensed contractor.  The contractor must test and document the boiler controls, safety devices and provide a copy of this document to you.  The inspection form must be posted near the boiler.

In addition, the boiler owners must test and document the following items on a monthly basis;

  • Check boiler/system water level in the sight glass
  • Check boiler pressure/temperature on gauge.
  • Drain/test low water fuel cut out
  • Manually/hand test boiler safety/relief valve
  • Check/observe burner operation

What happens if you don’t have a CSD-1 inspection?

Typically, if the boiler inspector comes out and finds that your CSD-1 is not up to date, they will give you a set time frame to get it done.  However, they may charge you for the return trip.


Seaman’s Mechanical possess all the necessary licenses to perform CSD-1 inspections.

Failed Heat Exchangers a Common Fall Problem

A heat exchanger is an integral part of any heating unit.  Every roof top unit or furnace has one.  The air that heats the rooms in your building travels through the heat exchanger while the flame from the burner heats the exchanger.

How a furnace works.

Over the course of time, the heat exchanger is subject to some very rough conditions.  High temperatures are the most obvious but also the elements if your heating unit is out side.  These extreme conditions can cause the heat exchange to rust out and develop holes.  When holes develop, this allows exhaust fumes to enter your warm air supply.

An annual inspection of your heat exchange is important to your health and the health of your heating equipment.  Checking the heat exchange is just one step Seaman’s performs in a Fall Heating Start and Check.
