Determining Product ocation
Before locating the HALLENGER check for
convenient locations to:
- Heating system piping
- Domestic water supply piping
- Venting
- Gas supply piping
- Electrical service
Ensure the appliance location allows the com-
bustion air and vent piping to be routed directly
through the building and terminate properly in
the same pressure zone outside with a minimum
amount of length and bends.
Ensure the area chosen for the installation of the
HALLENGER is free of any combustible
materials, gasoline and other flammable liquids.
Failure to remove or maintain the area
free of combustible materials, gasoline
and other flammable liquids or vapors
can result in severe personal injury,
death or substantial property damage.
Ensure the HALLENGER and its controls
are protected from dripping or spraying water
during normal operation or service.
The HALLENGER should be installed in a
location so that any water leaking from the
appliance, piping connections or relief valve
will not cause damage to the surrounding area
or any lower floors in the structure. When such
location cannot be avoided, it is recommended
that a suitable drain pan, adequately drained, be
installed under the appliance. The pan must not
restrict combustion air flow.

Combustion Air Contamination
If the CHA ENGER combustion air
inlet is located in any area likely to cause
or contain contamination, or if products,
which could contaminate the air cannot
be removed, the combustion air must be
repiped and terminated to another loca-
tion. Contaminated combustion air will
damage the appliance and its burner sys-
tem, resulting in possible severe personal
injury, death or substantial property
damage.
Do not operate a CHA ENGER if the
combustion air inlet is located near a
laundry room or pool facility. These
areas will always contain hazardous con-
taminants.
Pool, laundry products, common house-
hold and hobby products often contain
fluorine or chlorine compounds. When
these chemicals pass through the burner
and vent system, they can form strong
acids. These acids can create corrosion
of the heat exchanger, burner compo-
nents and vent system, causing serious
damage and presenting a possible threat
of flue gas spillage or water leakage into
the surrounding area.
Please read the information listed below.
If contaminating chemicals are located
near the area of the combustion air inlet,
the installer should pipe the combustion
air inlet to an area free of these chemi-
cals per SECTION VI of this installation
manual.
Potential contaminating products
- Spray cans containing chloro/fluorocar-
bons
- Permanent Wave Solutions
- hlorinated wax
- hlorine - based swimming pool chem-
icals / cleaners
- alcium hloride used for thawing ice
- Sodium hloride used for water soft-
ening
- Refrigerant leaks
- Paint or varnish removers
- Hydrochloric acid / muriatic acid
- ements and glues
- Antistatic fabric softeners used in
clothes dryers
- hlorine-type bleaches, detergents, and
cleaning solvents found in household
laundry rooms
- Adhesives used to fasten building prod-
ucts and other similar products
Areas likely to contain these products
- Dry cleaning / laundry areas and estab-
lishments

Ventilation Air Requirements
For installations, involving only the HAL-
LENGER, in which the minimum service
clearances are maintained as listed on page 5,
no ventilation openings are required.
For installations with less than the minimum
service clearances involving only the HAL-
LENGER, the space / enclosure must provide
two openings for ventilation. The openings
must be sized to provide 1 square inch [6
square centimeters] of free area per 1,000
BTUH [0.3 Kw] of appliance input. The open-
ings shall be placed 12 inches [30.5 cm] from
the top of the space and 12 inches [30.5 cm]
from the floor of the space.
For installations in which the HALLENGER
shares the space with air movers (exhaust fan,
clothes dryers, fireplaces, etc.) and other com-
bustion equipment (gas or oil) the space must
be provided with adequate air openings to pro-
vide ventilation and combustion air to the
equipment. To properly size the ventilation /
combustion air openings, the installer must
comply with the National Fuel Gas ode
NFPA 54, ANSI Z223.1 for installations in the
U.S or AN/ SA B149.1 for installations in
anada/
The space must be provided with venti-
lation / combustion air openings proper-
ly sized for all make-up air requirements
(exhaust fans, clothes dryers, fireplaces,
etc.) and the total input of all appliances
located in the same space as the CHA -
ENGER. The input of a CHA -
ENGER which uses combustion air
directly from the outside, is excluded
thus additional free area for the open-
ings is not required. Failure to provide
or properly size the openings could
result in severe personal injury, death or
substantial property damage.
Combustion Air and Vent Piping
The HALLENGER requires a ategory IV
venting system, which is designed for pressur-
ized venting and condensate.
The HALLENGER is certified as Direct Vent
(sealed combustion) appliance. A Direct Vent
appliance utilizes uncontaminated outdoor air
(piped directly to the appliance) for combustion.
Install combustion air and vent pipe as
detailed in the CHA ENGER PVC,
CPVC and SS Vent Supplement 2010-19
included in the appliance installation
envelope. Refer to instructions for parts
list and method of installation.

Removal of an Existing Boiler and or Water
Heater from a Common Vent System
When an existing boiler and/or water
heater is removed from a common vent-
ing 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 and/or water
heater, the following steps shall be fol-
lowed with each appliance remaining
connected to the common venting system
placed in operation, while the other appli-
ances remaining connected to the com-
mon 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 deter-
mine 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 remain-
ing connected to the common venting sys-
tem 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. lose 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 can-
dle, or smoke from a cigarette, cigar or pipe.
6. After it has been determined that each
appliance remaining connected to the com-
mon venting system properly vents when
tested as outlined above, return doors, win-
dows, 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 ode, ANSI Z223.1/NFPA 54
and/or AN/ SA 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 II of the
National Fuel Gas ode ANSI
Z223.1/NFPA 54 and/or AN/ SA
B149.1, Installation codes.
Do not install the CHA ENGER into a

Boiler Piping
SECTION IV - Boiler Piping
General Piping Requirements
- All plumbing must meet or exceed all local,
state and national plumbing codes.
- Support all piping using hangers. DO NOT
support piping by the appliance or its com-
ponents.
- Use isolation valves to isolate system com-
ponents.
- Install unions for easy removal of the
HALLENGER from the system piping.
Use a two wrench method when tighten-
ing piping onto the appliance connec-
tions. Use one wrench to prevent the
appliance piping from turning / twisting.
Failure to support the appliance piping
and connections in this manner could
cause damage to the appliance and its
components.
Pressure Relief Valve (PRV)
1. The HALLENGER has a ASME
Maximum Allowable Working Pressure of
43.5 PSI [3 bar]. The appliance is supplied
with a 30 psi [2 bar] pressure relief valve
and must be piped using the PRV connec-
tion as shown in Fig. 3 page 15.
2. To avoid potential water damage to the sur-
rounding area or potential scalding hazard
due to the operation of the relief valve, the
discharge piping:
- Must be connected to the discharge out-
let of the relief valve and directed to a
safe place of disposal.
- Length should be as short and direct as
possible. The size of the discharge line
should not be reduced, maintain the
same size as the outlet of the relief valve.
- Should be directed downward towards
the floor at all times. The piping should
terminate at least 6 inches [153 mm]
above any drain connection to allow
clear visibility of the discharge.
- Should terminate with a plain end, not
with a threaded end. The material of the
piping should have a serviceable temper-
ature rating of 250ºF [121º ] or greater.
- Should not be subject to conditions
where freezing could occur.
- Should not contain any shut-off valves
or obstructions. No shut-off valve
should be piped between the appliance
and relief valve.
Failure to comply with the guidelines on
installing the pressure relief valve and dis-
charge piping can result in personal injury,
death or substantial property damage.
ow Water Cut Off / CH Pressure Sensor
The ow Water Cut Off ( WCO) only
applies for space heating. Operation of
the WCO does not prevent a domestic
hot water call for heat.
- The HALLENGER is equipped with a fac-
tory installed pressure sensor type LW O.
- The minimum operating entral Heating
( H) system pressure is 7 psig [0.5 bar].
- If H System pressure is below 7 psig [0.5
bar] the main display will flash a soft lockout
of “LOP” followed by the pressure reading.
Once H system pressure is increased above
7 psi [0.5 bar] normal boiler operation will be
restored. If the appliance is installed as domes-
tic hot water heater only, set parameter 1
(installation type) to 2 (domestic only) to
eliminate the “LOP” error in the main display,
see page 52 for setting parameters.
- heck local codes if a LW O is required. If
so, determine if this device meets their
requirements.
