ADDITIONAL CHIMNEY INFORMATIONS
WARNING
CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each appliance connected to the venting
system being placed into operation could result in carbon monoxide poisoning or
death.
When an existing furnace is removed from a common venting system, the common venting
system is likely to be too large for proper venting of the appliances connected to it. At the time
of removal of the existing furnace, the following steps shall be followed with EACH appliance
remaining connected to the common venting system, while the other appliances remaining
connected to the common venting system are not in operation:
1. Seal any unused openings in the venting system.
2. Visually inspect the venting system for proper size and horizontal pitch and determine
there is no blockage or restriction, leakage, corrosion and other deficiencies which could
cause an unsafe operation.
3. Insofar as is practical, close all building doors and windows and all doors between the
space in which the appliances remaining connected to the common venting system are
located and other spaces of the building. Turn on clothes dryer and any appliance not
connected to the common venting system. Turn on any exhaust fans, such as range
hoods and bathroom exhausts, so they will operate at maximum speed. Do not operate
a summer exhaust fan. Close fireplace dampers.
4. Place in operation the appliance being inspected. Follow the lighting instructions. Adjust
thermostat operation so appliance will operate continuously.
