At the time of removal of an existing boiler, the
following steps shall be followed with each appliance
remaining connected to the common venting system
placed in operation, while the other appliances
remaining connected to the common venting system
are not in operation.
1. Seal any unused opening in the common venting
system.
2. Visually inspect the venting system for proper

no blockage or restriction, leakage, corrosion
and other deficiencies which could cause an
unsafe condition.

Follow the lighting instructions. Adjust
thermostat so appliance will operate
continuously.
