Gas Connection - COZY BFT101 Installation And Operation Instructions Manual

STEP 1. Make the gas connection between the manual shut off valve and regulator located inside
heater cabinet. Hold regulator when tightening connection to prevent damage to regulator
and internal tubing. See Figure 6 for completed installation.
NOTE: All piping and connection must be checked for leaks by the installer. If connections are not
exposed, a pressure test must be run. The appliance and its individual shut off valve must
be disconnected from the gas supply piping system during any pressure testing at pressures
in excess of ½ psig (3.5 kPa). The appliance must be isolated from the gas supply piping
system by closing its individual manual shut off valve during any pressure testing of the gas
supply piping system at test pressures equal to or less than ½ psig (3.5kPa).
