doors, win dows, exhaust fans, replace 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 /NFPA 54,. 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
Chapter 13 of the National Fuel Gas Code, ANSI
Z223.1 /NFPA 54.
C. Install Vent Connector.
1. Remove vent connector from vent accessory carton.
2. Remove gaskets, orice plate and hardware from
blower outlet ange.
3. Assemble orice plate gaskets, orice plate, and
vent connector. See Figure 7.
4. Secure vent connector with washers and locknuts.
Do not overtighten.
4. Do not install venting system components on the
exterior of the building except as specically
required by these instructions.
5. Do not connect vent connectors serving appliances
vented by natural draft into any portion of
mechanical draft system operating under positive
pressure.
6. Do not use cellular core PVC (ASTM F891),
cellular core CPVC, or Radel
®
(polyphenolsulfone).
7. Do not cover non-metallic vent pipe and ttings
with thermal insulation. Note: Non-metallic vent
cannot be used with this boiler.
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
deciencies 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 maxi mum
speed. Do not operate a summer exhaust fan. Close
replace dampers.
4. Place in operation the appliance being inspected.
Follow the Lighting (or Operating) Instructions.
Adjust thermo stat so appliance will operate
continuously.
5. Test for spillage at the drafthood relief opening after
5 minutes of main burner operation. Use the ame
of a match or candle, or smoke from a cigarette,
cigar or pipe.
6. After it has been determined that each appliance
remain ing connected to the common venting system
properly vents when tested as outlined above, return
Figure 7: Vent Connector Installation
D. Install Vent Pipe, General.
1. Plan venting system to avoid possible contact with
plumbing or electrical wires. Start at vent
connector. Work toward vent terminal.
2. Use non-combustible ¾ inch pipe strap to support
horizontal runs and maintain vent location and slope
while preventing sags in pipe. Do not restrict
thermal expansion or movement. Maximum support
spacing is 5 feet. Do not penetrate any part of the
venting system with fasteners.
