materials appropriate for gas installation.
To facilitate servicing, the air heater must be fitted
with an approved gas service tap and union fitting or
union tap adjacent to the appliance.
The inlet gas supply line must be installed so as to
permit the access door to be opened and to allow
removal of the slide out burner assembly.
Air heaters suspended by flexible suspension
materials or drop rods must be connected to the gas
supply using an approved flexible connector.
Sufficient slack must be provided in the connection
to allow for movement of the appliance. Use a
flexible connector of suitable size to reduce the
