| GAS CONNECTION |
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). |
