Removal Of An Existing Boiler From A Common Vent System; Vent/Combustion Air Piping And Materials - IDEAL Exalt Solo 110 Manual

CHAPTER 1 - PRE-INSTALLATION REQUIREMENTS
1.2. Removal of an Existing Boiler from a
Common Vent System
DANGER
Do not install the EXALT into a common
vent with any other gas or oil appliances.
This will cause flue gas spillage or appliance
malfunction, resulting
property damage, serious injury, or death.
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 instructions. Adjust thermostat
so appliance will operate 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 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 condition 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
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 of the National Fuel Gas Code, ANSI
Z223.1/NFPA 54 and/or CAN/CSA B149.1, Installation
Codes.

in substantial
The EXALT is certified per ANSI Z21.13 as a Category IV (in-
door air) or Direct Vent (sealed combustion) appliance. A
Category IV appliance utilizes uncontaminated indoor or
outdoor air (surrounding the appliance) for combustion.
A Direct Vent appliance utilizes uncontaminated outdoor
air (piped directly to the appliance) for combustion.
The EXALT requires a Category IV venting system which is
designed for pressurized venting and condensate.

Vent/Combustion Air Piping and Materials

NOTICE
• The EXALT appliance is supplied with an
acoustic dampening foam rubber insert
located in the appliance air inlet adaptor.
DO NOT remove this at installation.
• For EXALT 110 & 155 Models only, propane
conversions require an additional acoustic
foam insert to be fitted within the combustion
air piping. Consult LP Conversion Instructions
for proper fitting.
• The installation must conform to the
requirements of the
jurisdiction or, in the absence of such
requirements, to the National Fuel Gas Code,
ANSI Z223.1/ NFPA 54, and/or Natural Gas and
Propane Installation Code, CAN/CSA B149.1.
BEST PRACTICE BEST PRACTICE
To reduce the potential risks associated with
indoor contaminates (listed in Section 1.6
- pages 5 & 6), flammable vapors and tight
housing construction (little or no infiltration
air), it is recommended to pipe uncontaminated
combustion air directly from the outdoors to
the appliance. This practice also promotes
higher system efficiency by reducing heated
indoor air from being exhausted from the
building and replaced by cold infiltration air.
WARNING
The vent and combustion air materials (piping,
fittings and cement) must meet the listed
requirements in this manual.
Failure to comply with these material
requirements can result in substantial property
damage, serious injury, or death.
