9.33.

(1) The design and installation of central heating systems including requirements for combustion air, shall conform to the requirements in Part 6 and to this Section.

(2) The design and installation of air-conditioning systems shall conform to Part 6.

(3) Repairs, adjustments or component replacements that change the capacity or extent of safety of an existing heating, ventilating or air-conditioning system and that alter the method of operation shall conform to this Code.

(1) The design, construction and installation, including the provision of combustion air, of solid-fuel burning appliances and equipment, including stoves, ranges and space heaters, shall conform to CAN/CSA-B365-M, “Installation Code for Solid-Fuel-Burning Appliances and Equipment”.

(1) Where the building is in a location where the spectral response acceleration, S_a(0.2), is greater than 0.55, heating and air-conditioning equipment with fuel or power connections shall be secured to the structure to resist overturning and displacement.

(1) Residential buildings intended for use in the winter months on a continuing basis shall be equipped with heating facilities conforming to this Section.

(1) At the outside design temperature, required heating facilities shall be capable of maintaining an indoor air temperature of not less than,

(a) 22°C in all living spaces,

(b) 22°C in unfinished basements, and

(c) 15°C in heated crawl spaces.

(1) The outdoor conditions to be used in designing heating, ventilating and air-conditioning systems shall be the appropriate values for the Municipality as set out in Supplementary Standard SB-1, using 2.5 per cent design temperature criteria.

(1) This Subsection applies to every building that,

(a) contains a residential occupancy, and

(b) contains a fuel-burning appliance or a storage garage.

(1) Where a fuel-burning appliance is installed in a suite of residential occupancy, a carbon monoxide detector shall be installed adjacent to each sleeping area in the suite.

(2) Where a fuel-burning appliance is installed in a service room that is not in a suite of residential occupancy, a carbon monoxide detector shall be installed,

(a) adjacent to each sleeping area in every suite of residential occupancy that is adjacent to the service room, and

(b) in the service room.

(3) Where a storage garage is located in a building containing a residential occupancy, a carbon monoxide detector shall be installed adjacent to each sleeping area in every suite of residential occupancy that is adjacent to the storage garage.

(4) Where a storage garage serves only the dwelling unit to which it is attached or built in, a carbon monoxide detector shall be installed adjacent to each sleeping area in the dwelling unit.

(1) The carbon monoxide detector required by Article 9.33.4.2. shall,

(a) be permanently connected to an electrical circuit and shall have no disconnect switch between the overcurrent device and the carbon monoxide detector,

(b) be wired so that its activation will activate all carbon monoxide detectors within the suite, where located within a suite of residential occupancy,

(c) be equipped with an alarm that is audible within bedrooms when the intervening doors are closed, where located adjacent to a sleeping area, and

(d) conform to,

(i) CAN/CSA-6.19, “Residential Carbon Monoxide Alarming Devices”, or

(ii) UL 2034, “Single and Multiple Station Carbon Monoxide Alarms”.
