4. Do not install venting system components on the
exterior of the building except as specifically
required by these instructions.
5. Thickness of exterior walls through which vent-air
intake system may be installed: Minimum: 3",
Maximum: 12".
B.
Removal of Existing Boiler. For installations not
involving the replacement of an existing boiler, proceed
to Step C.
When an existing boiler is removed from a common
venting system, the common venting system is likely to
be too large for proper venting of the remaining
appliances. 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 openings in the common 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 condition.
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 dryers 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 (or Operating) Instructions.
Adjust thermostat so appliance will operate
continuously.
Table : Vent System Components 5. Test for spillage at the drafthood relief opening after
5 minutes of main burner operation. Use the flame
of a match or candle, or smoke from a cigarette,
cigar or pipe.
6. 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.
7. Any improper operation of the common venting
system should be corrected so the installation
conforms with the National Fuel Gas Code ,
ANSI Z223.1 and/or CAN/CSA B149.1, Installation
Codes . When resizing any portion of the common
venting system, the common venting system should
be resized to approach the minimum size as
determined using the appropriate tables in Part 11 in
the National Fuel Gas Code , ANSI Z223.1 and/or
CAN/CSA B149.1, Installation Codes .
C.
Install Vent Connector.
1. Remove vent connector from vent accessory carton.
2. Remove gaskets, orifice plate and hardware from
blower outlet flange.
3. Assemble orifice plate gaskets, orifice plate, and
vent connector. See Figure 9.
4. Secure vent connector with washers and locknuts.
Do not overtighten.
