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.
