Table 2: Vent System Components
A. General Guidelines.
1. Vent system installation must be in accordance with
National Fuel Gas Code, NFPA 54/ANSI Z221.3,
Venting of Equipment or applicable provisions of
local building codes. Contact local building or fire
officials about restrictions and installation inspection
in your area.
2. This appliance requires a Special Gas Vent.
Use Vent Connector and Vent Terminal in Vent
Accessory Carton provided with boiler (See Repair
Parts). The product is designed to use factory
supplied AL 29-4C
®
Stainless Steel vent system
components. The following manufacturers offer
similar AL 29-4C
®
components and are approved for
use with this product: Heat-Fab Inc. - Saf-T-Vent
(800-772-0739); Flex-L International Inc. - Star-34
(800-561-1980); Z-Flex U. S., Inc. - Z-Vent (800-
654-5600); and Protech Systems, Inc.- FasNSeal™
(800-766-3473) or equivalent. The use of these
alternate manufacturer's venting systems will require
adapters to connect to the factory supplied vent
connector and vent terminal. These adapters are not
supplied with this unit and should be obtained from
the supplier of the alternate manufacturer's venting
system. See Table 2 for complete list of Vent
System Components.
3. Vent length restrictions are based on equivalent feet
of vent pipe (total length of straight pipe in feet plus
5 equivalent feet for each 45° or 90° elbow). Do
not exceed the maximum certified vent length of 25
equivalent feet. The minimum certified vent length
is 7 equivalent feet. Do not include vent terminal or
vent connector in equivalent feet calculations.
4. Do not install venting system components on
the exterior of the building except as specifically
required by these instructions.
5. This PVCG boiler may only be sidewall vented; it
may not be vertically vented, as through a roof.
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.
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.
