4.9 Gas Supply and Piping

Gas piping should be supported by suitable hangers or

oor stands, not the appliance.

Review the following instructions before proceeding with the installation.

1. Verify that the appliance is tted for the proper type

of gas by checking the rating plate. FT will function properly at elevations up to 10,000 feet (3050 m). Refer to Section 4.12 for High Altitude Settings.

2. The maximum inlet gas pressure must not exceed 13" W.C. (3.2kPa). The minimum inlet gas pressure is 3.5" W.C. (1.0kPa).

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.

6. A sediment trap must be provided upstream of the gas controls.

7. All threaded joints should be coated with piping

compound resistant to action of liqueed 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.

11. Purge all air from gas lines.

CAUTION

PRV (included) must be installed immediately at the top of boiler outlet to PRV, with no valves between. Refer to Section 4.15 __________________________________________

WARNING:

Open ame 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 ring 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.

- DO NOT install automatic air vents on closed type expansion tank systems. Air must remain in the system and return to the tank to provide its air cushion.

- DO NOT use a closed type expansion tank in a system with the FT Combination Boiler. (Automatic air vent has been installed inside of the boiler.)

- If the combination boiler is installed in a closed water supply system, such as one having a

backow preventer in the cold water supply line,

it will control thermal expansion.

CAUTION

Use at least the MINIMUM pipe size for the entire

boiler loop piping (connecting boiler to and from the primary/secondary connection). Use only primary/secondary piping as shown.

Failure to follow these guidelines could result in system problems.

Diaphragm Type Expansion Tank

- The air in a diaphragm-type expansion tank is separated from the water by a exible rubber membrane.

When the tank is installed in and connected to the piping of the system, water enters the other side of the tank chamber and presses down on the diaphragm.

- You should always install an ‘Automatic Air Vent (Under gure ‘A’)’ on the top of the air separator to remove

residual air from the system.

- Automatic air vent has been installed on the inside of the FT combination boiler.

- The installation of additional air vent is optional.

- If the combination boiler is installed in a closed water supply system, such as one having a backow

preventer in the cold water supply line, it will control thermal expansion.

- Pump for primary loop is included with FT for < 15 ft.

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 eld

installation.

An approved ASME HV Pressure Relief Valve must be

installed on the DHW supply line as close to the unit as possible. V alve 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 oor.

3/4" 30psi

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 lling 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 efciency 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 oor drain

2. to neutralizer (optional kit)

3. to laundry tub

4. to condensate pump (eld 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 rst year of operation, please

check the neutralizer every few months for depletion.

Page 43

Apply only corrosion-resistant materials for the

condensate drain lines such as 1/2˝ PVC, CPVC,

Polypropylene pipe or included plastic hose.

For Category II and IV boilers, be installed so as to prevent accumulation of condensate; and

For Category II and IV boilers, where necessary , have means provided for drainage of condensate.

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.

SECTION 5. Control Display and Operation

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

will ash if an Outdoor Sensor or 0-10 Volt is not

connected to the appliance. To check the CH Target Temperature while using

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 ring.

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.

• Has the Boiler been vented with 3˝ or 2” PVC,

CPVC, Polypropylene or BH Special

Gas Vent (S636 PVC, CPVC) for Category IV

appliances in accordance with this manual and/or your local code?

• Is the vent termination at least 12˝ above the

exterior grade?

• Is the total vent length within the maximum vent length restriction?

• Have you checked the air/vent piping for leaks?

• Have you properly supported the vent termination?

• Are all vent runs properly supported?

• Is the vent sloped upward toward the vent

termination at a rate of 1/4˝ per foot (2% grade)?

Final check : Condensate drain installation

• Have you installed a condensate drain line from the Boiler to a drain or laundry tub?

Final check : Setting the DIP switches

• Are all DIP switches correctly set on the main board?

9.2 Final Check Lists (continued)

Final check : Connecting the power supply

• Please check that the power is 120V AC.

• Have you checked the polarity of the electrical connection?

Final check : Pressure relief valve

• Have you installed an approved pressure relief valve on the boiler?

• Is the pressure relief valve of CH Plumbing at least 1˝ in diameter?

• Is the pressure relief valve of DHW Plumbing at least 3/4˝ in diameter?

• Have you installed the pressure relief valve on the hot water outlet pipe near the Boiler?

Final check : Burner ame

• The burner ame must be checked periodically for a constant proper blue color.

• If the ame does not appear normal, the burner may need to be cleaned.

• If the burner needs to be cleaned, it must be performed by a qualied service technician.
