•
Place in operation the appliance being inspected. Follow the lighting
instructions. Adjust thermostat so appliance will operate continuously.
•
After it has been determined that each appliance remaining connected to the
common venting system properly vents when tested as outlined above, return
doors, windows, exhaust fans, fireplace dampers and any other gas-burning
appliance to their previous conditions of use.
•
Any improper operation of the common venting system should be corrected
so the installation conforms with the National Fuel Gas Code, ANSI Z223.1 -
latest edition. In Canada, all installations must conform with the current CAN/
CGA - B149.1 Installation Code and/or local codes.
1.4.1 Applications
