Removal of Existing Boiler From Common Vent System
When an existing boiler is rernoved from a common venting system,
the comrnon venting systern is likely to be too large for proper vent-
ing of the appliances remaining connected to it. At the time of re-
moval of an existing boiler, the following steps shall be followed with
each appliance rernaining connected to the common venting systern
placed in operation, while the other appliances rernaining connected
to the cornmon venting systern are not in operation.
1. Seal any unused openings in the comrnon venting systern.
2. Visually inspect the venting system for proper size and hori-
zontal pitch and deterrnine there is no blockage, or restrictions,
leakage, corrosion and other deficiencies which could cause an
unsafe condition.
3. In-so-far as is practical, close all building doors and windows
and all doors between the space in which the appliances remain-
ing connected to the common venting system are located and
other spaces of the building. Turn on clothes dryer and any ap-
pliance not connected to the common venting systern. Turn on
any exhaust fans, such as range hoods and bathroom exhaust, so
they will operate at maximum speed. Do not operate a summer
exhaust fan. Close fire darnpers.
4. Place in operation the appliance being inspected. Follow the
lighting instructions. Adjust therrnostat so appliances will oper-
ate continuously.
5. Test for spillage at the draft hood relief opening after 5 minutes
of main burner operation. Use the flame of a match or candle,
or the smoke frorn a cigarette, cigar or pipe.
6. After it has been deterrnined that each appliance remaining
connected to the common venting systern properly vents when
tested as outlined above, return doors, windows, exhaust fans,
fire place dampers, and any other gas-burning appliance to their
previous condition of use.
7. Any improper operation of the comrnon venting systern should
be corrected so the installation conforms with the National Fuel
Code, NFPA-54/ANSI -Z223.1 and/or the Natural Gas and
Propane Installation Code, CAN/CSA B149.1.. When resizing
any portion of the common venting systern, the comrnon vent-
ing system should be resized to approach the minimum size as
deterrnined using the appropriate tables in Chapter 13 of the
National Fuel Gas Code, NFPA-54/ANSI- Z223.1 and/or the
Natural Gas and Propane Installation Code, CAN/CSA B149.1.
The boiler should be placed to provide the most direct connections
to the combustion air, vent and systern piping as possible.
Place crated boiler as close to selected location as possible and
uncrate boiler. The uncrated boiler may be moved into position with
an appliance dolly or 2-wheel hand truck. The dolly or hand truck
should be inserted under the left hand side of the boiler. It is possible
to slide the boiler for a short distance on a smooth floor or surface.
Refer to manual section "locating the
boiler" (page 9 of this manual), for required
clearances for servicing and maintenance.
