PRE-INSTALLATION INSPECTIONS
P
ROCEDURE FOR SAFETY INSPECTION OF AN EXISTING APPLIANCE INSTALLATION
The following procedure is intended as a guide to aid in determining that an appliance is properly installed and is in a safe condition
for continuing use.
This procedure is predicated on central furnace, boiler and water heater installations, and it should be recognized that generalized
procedures cannot anticipate all situations. Accordingly, in some cases deviation from this procedure may be necessary to
determine safe operation of the equipment.
1. This procedure shall be performed prior to installation of the automatic vent damper device.
2. If it is determined there is a condition which could result in unsafe operation, the appliance should be shut off and the owner
advised of the unsafe condition. Do not install the automatic vent damper device until the unsafe condition has been corrected.
