__________________________________________
INSTALLATIONS IN CANADA require the use of
venting material certified to ULCS636. All Gas
vents connected to the FT, plastic, stainless
steel or otherwise must be certified to this ULC
standard. Appropriate selection of vent material is
very important for proper performance and safe
operation of the FT.
The flue temperature of the FT changes
dramatically with changes in operating water
temperature. Therefore, it is necessary to assess
the application of the boiler to determine the
required certified vent class. If the FT is installed in
an application where the outlet water temperature
exceeds 145°F, and/or installed in a closet, class
IIB or higher vent material is required. If the
system temperatures are unknown at the time of
installation, class IIB or higher venting material is
recommended.
IN CANADA all venting used must meet the
following requirements:
1.
ULC-S636 certified and marked
2.
The first 3 feet of venting must be accessible
for visual inspection.
3.
All components used in the vent system must
be from a certified manufacturer.
4 . Vent system components must not be mixed
with alternate manufacturers certified

components and/or unlisted components.
5 . The venting must be installed according
to the vent manufacturers installation
instructions.
The unit’s vent can terminate through the roof, or
through an outside wall.
Vent pipe must pitch upward, toward the vent
terminal, not less than 1/4” per foot, so that
condensate will run back to the FT to drain. Route
vent pipe to the heater as directly as possible.
Seal all joints and provide adequate hangers as
required in the venting system manufacturer’s
Installation Instructions. Horizontal portions of
the venting system must be supported to prevent
sagging and may not have any low sections that
could trap condensate. The unit must not support
the weight of the vent pipe.
WARNING
Failure to vent this Boiler in accordance with
these instructions could cause a fire, resulting
in severe property damage, personal injury or
death.
Do not interchange vent systems or materials
unless it is specified.
The use of thermal insulation covering pipe and
fittings is prohibited.
Do not apply an electric damper, draft hood or
vent damper with this Boiler.
Do not locate vent termination where exposed
to prevailing winds. Moisture and ice may fall
on surface around vent termination. To prevent
deterioration, surface must be in good repair
(sealed, painted, etc.).
4.5 General Location Guideline
1.Vent system installation must be in accordance
with Local codes or, in the absence of local codes,
the National Fuel Gas Code, ANSI Z224.1 /NFPA
54 and/or CSA B149.1, Natural Gas and Propane
Installation Code.
2.The Boiler is designed to be installed as a Direct
Vent (sealed combustion) type. The air for
combustion must be supplied directly from the
outside to the burner. Also, the flue gases must be
vented directly to the outdoors (through wall or roof).
3.Do not install venting system components on the
exterior of building except as specifically required by
these instructions
-Vent terminals must be at least 1 foot from any door,
window, or gravity inlet into the building.
-Maintain the correct clearance and orientation
between the vent and air intake terminals.
The vent and air intake terminals must be at the
same height and their center lines must be spaced
apart 12˝ minimum.
-The bottom of the vent and air intake terminal must
be at least 12˝ above the normal snow line. In no
case should they be less than 12˝ above grade
level.
-Do not install the vent terminal directly over
windows or doors.
-Air intake terminal must not terminate in areas that
might contain combustion air contaminates, such
as near swimming pools.
-For sidewall venting, the minimum horizontal
distance between any adjacent individual Module
(Boiler) vent terminations is twelve (12) inches. It
is better to be far more than 12 inches for avoiding
frost damage to building surfaces where vent
terminations are placed.
-The minimum horizontal distance between any
adjacent individual module (boiler) roof vent
endpiece is one (1) foot.

WARNING:
Open flame can cause gas to ignite and result in
property damage, severe injury, or loss of life.
NOTE: The FT appliance and all other gas appliances
sharing the gas supply line must be firing at maximum
capacity to properly measure the inlet supply pressure.
The pressure can be measured at the supply pressure
port on the gas valve. Low gas pressure could be an
indication of an undersized gas meter, undersized gas
supply lines and/or an obstructed gas supply line.
3.Refer to Table 7, Table 8, and Table 9 to size piping.
4.Run gas supply line in accordance with all
applicable codes.
5.Locate and install manual shutoff valves in
accordance with state and local requirements.

gas controls.
7.All threaded joints should be coated with piping
compound resistant to action of liquefied petroleum
gas.
8.The appliance and its individual shutoff valve
must be disconnected from the gas supply piping
during any pressure testing of that system at test
pressures in excess of 1/2 PSIG (3.45kPa).
9.The unit must be isolated from the gas supply
system by closing its individual manual shutoff valve
during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2
PSIG (3.45kPa).
10.The appliance and its gas connection must be leak
tested before placing it in operation.

The gas connection fitting on the unit is
1/2”(FTCF140) or 3/4”(FTCF199) female NPT.
The supply line must be sized for the maximum
output of the combination boiler model being
installed. If there are additional gas appliances
from the main supply line, you must measure
sizes of the supply line according to the
COMBINED total maximum BTUH draw for the
appliances as if they were all operating at the
same time.
Measure the length of the gas supply line from
the gas meter to the Combination boiler.
Use the tables in this manual or refer to the gas
line manufacturers sizing information to determine
the correct supply pipe size.
The gas shut-off valve in the gas supply line
should be installed close to the unit.
To facilitate any future maintenance, it is also
recommended that an approved gas union fitting
be installed in the supply line between the shut-off
valve and the 3/4” female NPT connection on the
Combination boiler.
1)Install an approved gas line pipe to gas line
connection to the combination boiler.
Include manual shut off valve and gas union
connection, as shown.
2)Test gas pressure to make sure it meets the
minimum standards and does not exceed .the
maximum standards for the combination boiler.
3)Leak test the gas line pipe before placing the
unit in operation. Use approved leak detector
liquid solutions only to check for leaks.
Do not operate the combination boiler until all
connections have been completed and the heat
exchanger is filled with water.

4.15 Pressure Relief Valves
External pressure relief valves must be installed.
Observe the following. Failure to comply with the
guidelines on installing the pressure relief valve and
discharge piping can result in personal injury, death
or substantial property damage.
WARNING
Do not operate this combination boiler before
installing a Pressure Relief Valve (PRV) that
is rated in accordance with the ASME Rating
Plate on the boiler.
This hot water boiler is provided with 30 psi safety relief
valve that complies with the ANSI/ASME Boiler and
Pressure Vessel Code, Section IV (“Heating Boilers).
(Model : CASE ACME F-82)
This safety relief valve (30 psi) is shipped loose for field
installation.
An approved ASME HV Pressure Relief Valve must be
installed on the DHW supply line as close to the unit
as possible. Valve size 3/4”, maximum 150 psi. Not
included with boiler.
For safety, the relief valve(s) must be installed into it’s
designed location and not be removed or plugged.
Failure to comply with the guidelines on installing the
pressure relief valves and discharge piping can result in
personal injury, death or substantial property damage.
Direct the discharge piping of the pressure relief valve
so that hot water will not splash on anyone or any
nearby equipment. Attach the discharge line to the
pressure relief valve and run the end of the line within
6-12″ (150-300mm) of the floor.
3/4" 30psi
Relief Valve

Shown is the model 140.
The model 199 is very similar.
WARNING
DO NOT install a CH pipe line relief valve with a
pressure higher than 30psi and DHW pipe line relief
valve with a pressure higher than 150psi. This is
the maximum allowable relief valve setting for the
combination boiler.
Test the operation of the valve after filling and
pressurizing system by lifting the lever. Make sure the
valve discharges freely. If the valve fails to operate
correctly, replace it with a new relief valve. Ensure that
the discharge capacity of the pressure relief valve is
equal to or greater than the maximum pressure rating
of the combination boiler.
Ensure that the maximum BTU/H rating on the
pressure relief valve is equal to or greater than the
maximum input BTU/H rating of the combination
boiler.
Pressure Relief Valve must be installed on the CH
supply line & DHW outlet line as close to the unit as
possible. (CH supply line: maximum 30psi, DHW
outlet line : maximum 150psi). No other valves should
be placed between the pressure relief valve and the
appliance.
This appliance has a high-temperature shut off switch
built in as a standard safety feature .Therefore a
“pressure only” relief valve is required.

4.16 Disposal of Condensate
High efficiency gas condensing Boilers create
condensation when operating. Condensation has
acidic (pH) of approximately 4-5.
Condensate must be drained in accordance with all
local regulations. Follow your local code with regards
to the disposal of condensation.
One of 4 disposal methods must be followed
1. to floor drain
2. to neutralizer (optional kit)
3. to laundry tub
4. to condensate pump (field supplied)
If a neutralizer is installed, periodic replacement of the
lime stone (or neutralizing agent) will be required. The
rate of depletion of the lime stone varies upon usage
of the boiler. During the first year of operation, please
check the neutralizer every few months for depletion.
Apply only corrosion-resistant materials for the
condensate drain lines such as 1/2˝ PVC, CPVC,
Polypropylene pipe or included plastic hose.
NOTICE
For Category II and IV boilers, be installed so as to
prevent accumulation of condensate; and
Condensate Trap and Drain Pipe
For Category II and IV boilers, where necessary, have
means provided for drainage of condensate.
(viewed from left front corner and as if
the side and front panel are
semi-transparent).
AVIS
les chaudières de catégories II et IV doivent être
installées de façon à empêcher l'accumulation de
condensat; et
si nécessaire, les chaudières de catégories II et IV
doivent être pourvues de dispositifs d'évacuation du
condensat.
CAUTION
Condensate is mildly acidic (pH=5), and may harm
some floor drains and/or pipes, particularly those
that are metal. Ensure that the drain, drainpipe, and
anything that will come in contact with the condensate
can withstand the acidity, or neutralize the condensate
before disposal. Damage caused by failure to install
a neutralizer kit or to adequately treat condensate
will not be the manufacturer’s responsibility.

Outdoor Reset varies the control setpoint based on
the outdoor temperature. The reset function works
as shown in Figure ‘CH Outdoor Reset’. When the
outdoor air temperature reaches 6:OH “high outdoor
temperature setpoint”, the control point setting is
adjusted to 17:cL “low boiler temperature setpoint”.
When the outdoor air temperature reaches 7:OL “low
outdoor temperature setpoint” the control setpoint is
adjusted to 16:cH “high boiler temperature”.
Default outdoor reset setpoint is 100°F (38°C)
The Outdoor Temperature Mode Icon on the display

Connect to terminal strip as outlined 4.17 Electrical Connections.
NOTE: 0 - 10VDC terminals may not be used for both outdoor reset and 0 - 10VDC temp
setpoint simultaneously.
5.10 External Set Point Temperature Control
A signal from a building management system may be connected to the appliance to enable remote
control. This signal should be a 0-10 volt DC signal. When this input is enabled, a building control
system can be used to control the set point temperature of the appliance.
The control interprets the 0-10 volt signal as follows; when the signal is between 0 and 1.5 volts, the
appliance will be in standby mode, not firing.
When the signal rises above 1.5 volts, the appliance will ignite. As the signal continues to rise
towards its maximum of 10 volts, the appliance will increase in set point temperature. Adjust 16:cH
and 17:cL to set MIN and MAX boiler water temperatures respectively.
Connect a building management system or other auxiliary control signal to the terminals marked
for this purpose on the appliance terminal block (shown in Piping Diagrams, this manual). Caution
should be used to ensure that the 0-10 VOLT + connection does not become connected to ground.
Connect to terminal strip as outlined 4.17 Electrical Connections.
NOTE: 0 - 10VDC terminals may not be used for both outdoor reset and 0 - 10VDC temp
setpoint simultaneously.
