a) operating at regulated outlet pressures not to exceed 11 in wc (2.74 kPa); or
b) operating at regulated outlet pressures in excess of 11 in WC (2.74 kPa) but not greater than 5 psi (34.5kPa).
1.6 Built-in appliances may be for:
a) connection to a fixed fuel piping system; or
b) connection to a remote self-contained propane gas supply system (see Clause 3, Definitions),provided the appliance is supplied with remote mounting and retention means for the attachment of a single cylinder with a maximum size in accordance with Clause 1.2b)i) or Clause 1.2b)i) and instructions for installing the mounting and retention means within the built-in enclosure.CSA 2.41 pdf download.
