maintain specified indoor environmental conditions under specified outdoor
This Standard also provides restrictions on selecting the output capacity of a
specific space heating or cooling appliance or group of appliances.

buildings of residential occupancy as defined in Subsection 188.8.131.52.(a) Group c
of the National Building Code of Canada, where the appliances are permanently
