15.1 Pulsed air heating systems

Subclass 15.1

This subclass authorizes construction work which is reserved exclusively for master pipe-mechanics under the Act respecting master pipe-mechanics (CQLR, c. M-4) and which concerns forced-air heating systems.

It also authorizes construction work which is not already authorized by the first paragraph and which concerns forced air heating systems, in particular those relating to propane burner systems and those included in subclass 15.1.1.

In addition, this subclass authorizes construction work relating to forced air systems for heating and air conditioning. However, work relating to heating and air conditioning devices forming part of such systems can only be carried out on condition that the contractor also holds the appropriate subclass 15.9 or 15.10.

Finally, it authorizes related construction work.

Additional explanations

This subclass includes construction work in subclass 15.1.1.

This subclass, without going beyond the regulatory framework , authorizes in particular construction work relating to:

  • when installing the heater
  • when installing or replacing the burner
  • the installation of the gas supply piping and the connection to the meter or the cylinder and the connection to the burner
  • the installation of the fuel oil supply piping, the tank and the connection to the tank as well as to the burner
  • installing wall vents
  • to the chimney connection
  • connection and installation of prefabricated chimneys
  • the installation of a liner inside the chimney casings
  • the installation of control and regulation systems for forced air heating systems for heating
  • the demolition of forced air heating systems
  • installation of the air distribution network
  • when installing the HRV when it is part of the forced air heating system.

Additional details

Please note that this subclass does not include similar work.

Construction work for a propane burner system (not part of a forced air heating system) requires subclass 15.6.

The contractor who carries out construction work relating to a device which heats and air conditioners must also have the refrigeration subclass (15.9 or 15.10) relevant to the work.

Construction work on an electrical installation is reserved exclusively for contractors or owner-builders holding subclass 16.0.
