403.3 Mechanical system piping insulation (Mandatory). Mechanical system piping capable of carrying fluids above 105°F or below 55°F shall be insulated to a minimum of R-3.
Exceptions – HVAC equipment & run out piping 4 feet from valve.
PIPE INSULATION 403.4PIPE INSULATION 403.4
Circulating hot water systems (Mandatory). All circulating service hot water piping shall be insulated to at least R-2. Circulating hot water systems shall include an automatic or readily accessible manual switch that can turn off the hot water circulating pump when the system is not in use.
Exception does not make sense.

Additional requirements for equipment sizing are included by an inspection for compliance with the Michigan Residential Code. M1401.3
SYSTEMS SERVING MULTIPLE SYSTEMS SERVING MULTIPLE RESIDENCES 403.7RESIDENCES 403.7 For systems serving multiple dwelling units
documentation has been submitted demonstrating compliance with 2009 IECC Commercial
Building Mechanical and/or Service Water Heating (Sections 503 and 504).
No code sections in the book!
Swimming Pools:403.9 Heated swimming pools have an
on/off heater switch. Pool heaters operating on natural gas or LPG have an electronic pilot light. Timer switches on pool heaters and pumps are present.
Exceptions: Where public health standards
require continuous pump operation. Where pumps operate within solar- and/or waste-heat-recovery systems.
Heated swimming pools have a cover on or at the water surface. For pools heated over 90 degrees F the cover has a minimum insulation value of R-12.
SIMULATED PERFORMANCE ALTERNATIVE SECTION 405
Mandatory requirements. Compliance with this section
requires that the mandatory provisions identified in Section 401.2 be met.
All supply and return ducts not completelyinside the building thermal envelope shall be insulated to a minimum of R-6.
