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 replace
dampers.
4. Place in operation the appliance being inspected. Fol-
low the lighting instructions. Adjust thermostat so appli-
ance will operate continuously.
5. Test for spillage at the draft hood 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
remaining connected to the common venting system
properly vents when tested as outlined above, return
doors, windows, exhaust fans, replace dampers, and
any other gas-burning appliance to their previous con-
dition 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,
and/or the Natural Gas and Propane Installation Code,
CAN/CSA B149.1. 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,
and/or the Natural Gas and Propane Installation Code,
CAN/CSA B149.1.
C.9.c. Termination
!
CAUTION:
A listed vent cap terminal suitable for connection to the
Category IV vent materials, adequately sized, must be
used to evacuate the ue products from boilers.
The vent termination and cap must be installed as follows:
•
Must terminate vertically outside the building at least 2
ft above the highest point of the roof that is within 10 ft.
•
Should have minimum clearance of 4 ft horizontally
from, and in no case above or below (unless a 4 ft
horizontal distance is maintained), electric meters, gas
meters, regulators and relief equipment.
•
The minimum distance from adjacent public walkways,
adjacent buildings, openable windows and building
openings shall not be less than those values speci ed
in the National Fuel Gas Code, ANSI Z223.1/NFPA 54
and/or the Natural Gas and Propane Installation Code,
CAN/CSA B149.1.
•
Minimum twelve (12) inches above grade plus normally
expected snow accumulation or seven (7) feet above
grade if located adjacent to public walkways.
•
DO NOT INSTALL over public walkway where local
experience indicates condensation or vapor from the
boiler creates a nuisance or hazard.
•
Minimum three (3) feet above any forced air inlet lo-
cated within ten (10) feet of the vent termination.
•
Minimum four (4) feet below, four (4) feet horizontally
or one (1) foot above any door, window or gravity air
inlet.
•
Minimum twelve (12) inches from corners of building.
•
Flue vents supported only by ashing and extended
above the roof more than 5 ft. should be secured by
guy-wires or braced to withstand snow and wind loads.
C.10. C
ONDENSATE
D
RAINS
Each Triton Series boiler contains a condensate drain.
In addition, most vent congurations require a drain “T”
located in the vent piping. Pipe each condensate drain
separately to a oor drain or condensate pump/sump.
!
WARNING:
•
Failure to properly pipe the condensate drainage sys-
tem will greatly reduce boiler life. Do not install plugs,
caps or valves on condensate piping.
•
Do not manifold boiler condensate drains or vent
drains together.
•
Do not crimp condensate lines or reduce drain line
inner diameter size.
•
Each condensate drain must contain a siphon/pigtail
or trap to prevent ue gas ow through the conden-
sate piping. The height of the top of the syphon/pigtail
loop or trap shall not exceed the height of the con-
densate drain outlet.
•
Do not use material that is not approved for use with
ue gas condensate for condensate piping.
•
Use continuous Teon, high temperature resistant sili-
cone tubing, or other tubing material compatible with
ue gas condensate for condensate piping.
•
Do not install valves on condensate drain lines.
