If damage is found, save the packing material and contact the carrier immediately.
2. Remove the gas fired boiler from the skid.
Move the boiler to its permanent location.
Installation Codes
The installation of this unit must conform to local codes or, in the absence of local code,
to the National Fuel Gas Code, ANSI Z223.1-Latest Edition. Where required by the authority
having jurisdiction, the installation also must conform to the Standards for Controls and Safety
Devices for Automatically Fired Boilers, ANSI/ASME CSD-1.
For Canada, the installation of this unit must conform to all Canadian local codes as applicable or,
in the absence of local codes, to the Canadian installation code, CAN/CGA-B149, and CSA C22.1
Canadian Electrical Code Part 1.
Locating the Gas Fired Boiler
Locate the gas fired boiler as near to the exhaust venting system as practical. Air openings on the front,
back and sides of the boiler housing should not be obstructed since they supply air to the combustion
chamber.
The location of the boiler should be chosen with regard to venting dimensions, convenient access to
piping, ventilation of operating components and accessibility for service and cleaning.
The boiler shall be installed such that the gas ignition system components are protected from water
(dripping, spraying, rain, etc.) during appliance operation and servicing procedures such as pump
replacement, burner cleaning and the like.
When the unit is located in an unconfined space of a building, air infiltration may be adequate to provide
air for combustion and ventilation. Where normal infiltration does not provide the necessary air , outside
air must be introduced.
In buildings of unusually tight construction, or when locating the unit in a confined space, additional air
must be provided. For confined spaces, two (2) permanent openings shall be provided:
One (1) opening within 12" of the ceiling and one (1) within 12" of the floor of the enclosing space.
Each opening shall be at least 1 square inch per 1,000 BTU/HR heater input of the total for all appliances
in the area, but not less than 100 square inches. These openings shall freely connect with areas having
adequate infiltration from outside.
The boiler should be placed beside the Champion dishwasher model that it serves so that all plumbing and
electrical connections between the boiler and the dishwasher can be made per Champion's specifications.
If installed in a finished area, provisions should be made for drainage of any accidental spillage or
leakage of water. The boiler pressure relief valve and back-flow preventor should be piped to a
drain to protect from the occasional discharge of water.

INTRODUCTION
Clearance to Combustibles (Cont'd)
The clearances listed in the Clearance Chart (See Fig. 4) are minimum clearances. Clearances for service
accessibility to the gas fired boiler must take preference over the fire protection clearances. The installer
should allow a minimum of 12" for servicing at the sides and back of the boiler if possible.
!
WARNING:
Provide a screen or other type of protective barrier around exposed vent pipe to reduce burn
hazards where inadvertent contact with hot vent surfaces by personnel can occur.
Air for Combustion and V entilation
General
An adequate supply of air for combustion and ventilation must be supplied in accordance with
Section 5.3 of the National Fuel and Gas Code, ANSI Z223.1-Latest Edition or applicable
provisions of the local building codes for gas utilization equipment installed in buildings that
require air for combustion, ventilation, and the dilution of flue gases from within the building.
For Canada, the installation of this unit must conform to all Canadian local codes as applicable or,
in the absence of local codes, to the Canadian installation code, CAN/CGA-B149.
Install the equipment in a location where the ventilation facilitates the satisfactory combustion of
gas, proper venting and maintenance of ambient temperature at safe limits under normal conditions
of use.
Equipment should be located so as not to interfere with proper air circulation.
When normal infiltration does not provide the necessary air, outside air must be introduced.
In addition to air needed for combustion, process air must be provided as required for:
cooling of equipment or material, controlling the dew point, heating, drying, oxidation or dilution, safety
exhaust, odor control, and air for compressors.
In addition to air needed for combustion, ventilation air must also be supplied, including all air required
for comfort and proper working conditions for personnel.
Unconfined Space
An unconfined space (such as an open basement) must have a minimum volume of 50 cubic feet per
1,000 BTU/HR input of the total of all appliances in the area. Adjoining rooms may be counted as one
area only if there are no doors between the rooms.
Air Contaminants
Compounds bearing contaminants such as chloride, fluoride, iodide, and bromide, when present in certain
concentrations in the air supplied for combustion to the boiler, can result in an accelerated and severe
corrosion condition in the heat exchanger and/or the venting systems. Avoid storing or using chemicals
containing these compounds in the vicinity of the boiler if at all possible.
!
CAUTION:
Combustion air must not be contaminated by corrosive chemical fumes which can damage
the heat exchanger in the boiler.

WARNING:
Read all of the instructions included with your machine before
attempting any installation. Faulty vent installation can cause
improper operation of the gas fired boiler..
Vent Installation
General
The CSS-130 gas fired boiler is approved as a Category I Boiler when the following vent
installations are used:
1. Common vent installation
2. Vertical through-the-roof vent installation
3. Masonry chimney vent installation using Type B-1 Double-wall vent.
The CSS-130 is approved as a Category III Boiler when a horizontal through-the-wall vent
installation is used. This installation is a positive pressure venting system and requires that
all connections be sealed with an approved high temperature sealant.
Refer to the specific venting installation section for detailed instructions.
Vent installation must be in compliance with Part 7 "Venting of Equipment", of the
National Fuel Gas Code; ANSI Z223.1-Latest Edition, (In Canada, to the Canadian installation code, CAN/CGA-B149), local codes, or ordinances, these instructions, and good
trade practices.
Existing Boiler Removal
When an existing boiler is removed from a venting system serving other appliances, the
venting system is likely to be too large to properly vent the remaining attached appliances.
Perform the following steps individually with each appliance that remains connected to the
common vent system placed in operation with the other appliances remaining connected to
the common venting system but not in operation.
If improper venting is observed during any of the following tests, the common venting system
must be corrected.
1. Seal any unused openings in the common venting system.
2. Visually inspect the vent system for proper size and horizontal pitch and determine that
there is no blockage or restriction, leakage, corrosion, and other deficiencies which could
cause an unsafe condition.
3. As far as practical, close all building doors and windows plus all doors between the space
which the appliances remain connected to the common vent system are located and the
other spaces of the building.

INSTALLATION
Existing Boiler Removal (Cont'd)
4. Turn on clothes dryers and any appliance NOT connected to the common vent 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.
5. Follow the lighting instructions of the appliance being tested and place the appliance in
operation. Adjust the thermostat so the appliance operates continuously.
6. After five minutes of main burner operation, test for air spillage at the draft hood relief
opening. Use the flame of a match or candle, or the smoke from a cigarette, cigar, or pipe.
7. Repeat steps for each appliance connected to the common vent system.
After it has been determined that each appliance remaining connected to the common vent
system properly vents when tested as outlined above, return all doors, windows, exhaust fans,
fireplace dampers, and any other gas burning appliance to their previous conditions of use.
If necessary the common vent should be re-sized to approach the minimum size as
determined by using the appropriate tables in Appendix G in the National Fuel Gas Code,
ANSI Z223.1-Latest Edition.
For Canada, the installation of this unit must conform to all Canadian local codes as applicable or,
in the absence of local codes, to the Canadian installation code, CAN/CGA-B149.
The boiler should not be connected to a chimney flue serving a separate appliance that is designed
to burn solid fuel.
No portion of the venting system can extend into, or pass through any circulating air duct or plenum.
All vent pipe passing through floors, walls, and ceilings must be installed with the listed clearance to
combustible materials and be fire stopped according to local codes.
Common V enting
Vent connectors serving Category I appliances shall not be connected to any portion of the mechanical
draft systems operating under positive pressure such as Category III or Category IV venting systems.
When two or more vent connectors enter a common gas vent, chimney flue, or a single-wall metal pipe,
the smaller of the connectors shall enter at the highest level consistent with the available headroom or
clearance to combustible material.
Vent connectors shall be firmly attached to draft hood outlets or flue collars by sheet metal screws or
other approved means, except vent connectors of listed Type B-1 vent material (which shall be assembled
in accordance with the vent manufacturer's instructions). Fasten joints between sections of single-wall
connector piping with sheet metal screws or other approved means.
