CHIMNEY & VENT PIPE CONNECTIONS

e vent installation must be in accordance with Part

7, Venting of Equipment, of the latest revision of the National Fuel Gas Code, ANSI Z223.1/NFPA 54 or applicable provisions of the local building codes. Canadian installations must comply with CSA B149.1 or .2 Installation Code. Improper venting can result in excessive levels of carbon monoxide which can result in severe personal injury or death!

Never modify or alter any part of the boiler’s dra

hood. is includes the removal or alteration of any baes. Never install a vent pipe of a diameter dierent than that of the boiler dra hood ue collar. Failure to comply with this warning can result in severe personal injury or death!

Always provide a minimum clearance of 6 in,152 mm between type C vent pipe and any combustible materials. Type B1 vent may be used, clearance between it and any combustible material must be as listed.

Chimney Inspection & Sizing

A thorough inspection of the masonry chimney must be performed to ensure that the chimney is clean, properly constructed, lined and sized. Exterior masonry chimneys should not be used unless properly lined to prevent condensation and dra problems. Table 4 lists the equivalent breeching and ue sizes required for the boiler/water heater.

Table 4 Equivalent Breeching and Chimney Size

100 5 127 150 6 152 200 7 178 250 8 203 300 8 203 350 9 229 400 10 254

Note: These sizes are based on a 20 ft, 6.1 m chimney height.

Size

When more than one appliance is connected to the same chimney ue, the ue must be large enough to safely vent the combined output of all the appliances.

If an appliance using any type of a mechanical dra

system operating under positive pressure is connected to a chimney ue, never connect any other appliances to this ue. Doing so can result in the accumulation of carbon monoxide which can cause severe personal injury or death!

Vent Connections

Always use a type B or single wall galvanized metal vent pipe the same diameter as the dra hood ue collar, Table 4. Use the shortest, straightest vent system possible for the installation. If horizontal runs exceed 6 , 1.8 m they must be supported at 6 ,

1.8 m intervals with overhead hangers. e vent system should be sloped up toward the chimney at a minimum rate of 1/4 in/, 20 mm/m and terminate ush with the inside of the chimney ue. Fasten each connection with at least 3 corrosion resistant sheet metal screws.

Failure to maintain minimum clearances between vent

connectors and any combustible material can result in a re causing extensive property damage, severe personal injury or death!

COMMON VENT SYSTEMS

If an existing boiler/water heater is removed from a common venting system, the common venting system may then be too large for the proper venting of the remaining appliances connected to it. At the time of removal of an existing boiler/water heater, 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.

Au moment du retrait d’une chaudière existante, les mesures suivantes doivent être prises pour chaque appareil toujours raccordé au système d’évacuation commun et qui fonctionne alors que d’autres appareils toujours raccordés au système d’évacuation ne fonctionnent pas: système d’évacuation.

a) Seal any unused openings in the common venting system.

Sceller toutes les ouvertures non utilisées du sys-tème d’évacuation.

b) Visually inspect the venting system for proper size and horizontal

pitch and determine there is no blockage or restriction, leakage, corrosion and other deciencies which could cause an unsafe condition.

Inspecter de façon visuelle le système d’évacuation pour

déterminer la grosser et l’inclinaison horizontale qui conviennent et s’assurer que le système est ex-empt d’obstruction, d’étranglement de fruite, de corrosion et autres défaillances qui pourraient présenter des risques.

Finned copper tube gas boilers & water heaters – Boiler Manual

c) 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 bath-room exhaust, so they will operate at maximum speed. Do not operate a summer exhaust fan for a boiler installation. Close replace dampers.

Dans la mesure du possible, fermer toutes les portes et les fenêtres

du bâtiment et toutes les portes entre l’espace où les appareils toujours raccordés du système d’évacuation sont installés et les autres espaces du bâtiment. Mere en marche les sécheuses, tous les appareils non raccordés au système d’évacuation commun et tous les ventilateurs d’extraction comme les hoes de cuisinère et les ventilateurs des salles de bain. S’assurer que ces ventilateurs fonctionnent à la vitesse maximale. Ne pas faire fonctionner les ventilateurs d’été. Fermer les registres des cheminées.

d) Place in operation the appliance being inspected. Follow the

lighting instructions. Adjust thermostat so appliance will operate continuously.

Mere l’appareil inspecté en marche. Suivre les instructions

d’allumage. Régler le thermostat de façon que l’appareil fonctionne de façon continue.

e) Test for spillage at the dra hood relief opening aer 5 minutes

of main burner operation. Use the ame of a match or candle, or smoke from a cigaree, cigar or pipe.

Faire fonctionner le brûleur principal pendant 5 min ensuite,

déterminer si le coupe-tirage déborde à l'ouverture de décharge. Utiliser la amme d'une allunee ou d'une chandelle ou la fumée d'une ciga-ree, d'un cigare ou d'une pipe.

f) Aer 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, replace dampers and any other gas-burning appliance to their previous condition of use.

Une fois qu’il a été déterminé, selon la métode indiquée ci-

dessus, que chaque appareil raccordé au système d’évacuation est mis à l’air libre de façor adéquate. Remere les portes et les fenêtres, les ventilateurs, les registres de cheminées et les appareils au gaz à leur position originale.

g) 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. 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 in the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and or CAN/CGA B149 Installation Codes.

Finned copper tube gas boilers & water heaters – Boiler Manual

Variable Water Flows

Figure 5 shows a typical primary/secondary piping system. A dedicated pump is used to maintain a constant water ow through the boiler. is boiler pump is sized to overcome the head loss of the boiler and near piping while supplying the ow rate required to maintain the desired temperature rise across the boiler heat exchanger. e system pump is sized to provide the required ow to the heating system.

Low Return Water Temperatures

To prevent the problems associated with condensation of the products of combustion due to low return water temperatures a primary/secondary piping system with a bypass and bypass valve must be installed, see Figures 6 and 6A. e bypass and bypass valve must be sized the same as the secondary piping. A balancing valve must also be installed in the supply side of the secondary piping downstream of the bypass. e balancing valve should be adjusted to divert some of the heated discharge water into the return water until the required inlet water temperature is achieved. e primary and secondary pumps should be sized to provide the required ow through each system.

Multiple Boiler Systems

Systems using multiple boilers can also be installed using a primary/ secondary manifold system, Figure 7.

Piping For Use With Cooling Units

e boiler, when used in connection with a refrigeration system, must be installed so the chilled medium is piped in parallel with the boiler. Appropriate valves must be used to prevent the chilled water from entering the boiler.

When a boiler is connected to a heating coil that may be exposed to refrigerated air from an air handling device, the piping system must be equipped with ow-control valves or some other automatic means of preventing gravity circulation of the boiler water during the cooling cycle.

DOMESTIC WATER SUPPLY PIPING

Proper controls must be used to prevent water

supplied for domestic use from exceeding 130°F, 54°C or a scald injury will occur! When higher water temperatures are required for appliances such as a dishwasher, a mixing valve or some other tempering means must be installed. Households with small children may require water temperatures less than 120°F, 49°C. Local codes must be complied with!

General Piping Requirements

Ensure that the water heater is equipped with bronze headers. Piping and components connected to the water heater must be suitable for use with potable water. e water heater must not be connected to any heating system piping or components previously used with a non-potable water heating appliance. No toxic chemicals, such as those used for boiler treatment, are to be introduced into any potable water used for space heating. If a hot water storage tank is used in the system, it must be equipped with a temperature and pressure relief valve that complies with ANSI Z21.22 or CAN-4.4 and CAN-4.6.

e storage tank must be located as close to the water

heater as possible to prevent excessive head loss which will reduce ow.

Water Chemistry

e required temperature rise across the water heater is based on water having a hardness between 5 and 25 grains per gallon with a level of dissolved solids not exceeding 350 ppm. Water having a hardness less than 5 grains can cause excessive corrosion of the heat exchanger. Water that has a hardness greater than 25 grains per gallon and/or a level of dissolved solids exceeding 350 ppm will require a recalculation of the pump size and temperature rise.

A cupro-nickel heat exchanger may also be required. e manufacturer should be consulted when these water conditions are encountered. See Table 9A.

RBI water heaters are designed to run scale free. Due to the extreme variables of water conditions world wide it is necessary to consider pH values and water hardness in relationship to scaling. It is crucial to consider these two variables when making heat exchanger and pump selections. If local water conditions are extreme follow the guidelines in the Heat Exchanger Selection Table (Table 9A) and the Pumping Performance Table (Table 9B). Scale free operation can be achieved by using water with a hardness between 8 and 18 and by maintaining the pH between 5 and 9. Follow the conditions listed under NORMAL in the table. In some areas of the country additional precautions must be observed due to unusual characteristics of the local water supply. Call the nearest RBI representative for details.

To properly size the pump a grain hardness and pH test must be taken at the installation site before the order is placed. Proper pump sizing will improve heater performance and help ensure heater longevity.

Expansion Tank

An expansion tank or other means to control thermal expansion must be installed in the water heating system if back ow prevention devices are installed.

Finned copper tube gas boilers & water heaters – Boiler Manual

Pump Requirements

is low-mass water heater requires a continuous minimum water ow for proper operation. e factory recommended circulating pump has been sized to overcome the head loss of the water heater plus a 30 foot piping loop under normal water conditions. Table 9B provides the heat exchanger pressure drop chart and temperature rise table. etemperaturerise acrossthewater

heatermust neverexceed 30°F, 16.7°C.

e max imum allowable ow rate through a Spectrum

water heater is 92 GPM, 5.8 L/s (2-pass heat exchanger) and 46 GPM, 2.9 L/s (4-pass heat exchanger). e cupro-nickel heat exchanger allows for 100 GPM, 6.3 L/s (2-pass heat exchanger) and 50 GPM, 3.2 L/s (4-pass heat exchanger). See Table 9B.

Cold Water Supply

e cold water supply must be piped to the storage tank on the water heater’s outlet piping between the water heater and the hot water storage tank. is will prevent untempered water from entering the water heater, see the Temperature Rise Control section. A typical water heating system is shown in Figures 8 and 9.

Temperature Rise Control

Water returned to the water heater inlet must not be less than 110°F, 43°C or excessive condensation of the products of combustion will damage the water heater voiding the warranty. e method outlined below can be employed to prevent this condition from occurring.

A balancing valve should be installed on the outlet side of the water heater for purposes of adjusting the ow rate through the heat exchanger. ermometers are installed on both the inlet and outlet of the water heater for determining the temperature rise through the unit.

e proper velocity through the water heater must be maintained in accordance with Table 9B for ecient operation and long life. If the temperature rise through the water heater is lower than recommended, the water velocity is too high. Premature erosion of the heat exchanger will occur. Conversely, if the temperature rise is higher than recommended in Table 9B the ow rate is too low.

Scaling and soening of the heat exchanger will occur.

Thermostatic Mixing Valve - Water Above 140°F, 60°C

Water can be stored at temperatures above 140°F, 60°C provided that a thermostatically controlled mixing valve is used to temper the hot water to an acceptable temperature before it’s supplied for domestic use.

e mixing valve MUST be set to prevent a scald injury from occurring, see the caution against scalding.

Storage of water for domestic use above 140°F, 60°C will provide an increased quantity of tempered water and help prevent the growth

of water born bacteria.

GAS SUPPLY PIPING

Check the boiler/water heater rating plate

to make sure that the boiler/water heater is for the type of gas that will be used. If it isn’t, do not connect the boiler/water heater to the gas supply. Gas supply piping must be in accordance with the National Fuel Code, ANSI Z223.1-latest revision or applicable provisions of the local building codes. Canadian Installations must comply with CAN/CGA B149.1 or .2 Installation Code. Failure to comply with this warning can result in extensive property damage, severe personal injury or death!

e Spectrum boiler/water heaters come from the factory ready to be piped to the gas supply. If for any reason the boiler/water heater is not for the type of gas available at the installation site, call the nearest RBI representative to resolve the problem.

A minimum gas supply pressure of 5 in, 127 mm WC

natural or 12 in, 305 mm WC propane and maximum gas supply pressure of 14 in, 356 mm WC natual or propane, must be available at the safety shuto valve inlet with the unit(s) operating.

Table 10 should be used to ensure that the gas supply piping is sized properly. If more than one appliance is supplied by the same supply pipe, the piping must be sized based on the maximum possible demand. Do not neglect the pressure drop due to pipe ings. Table 10 should be used in conjunction with Table 11 to ensure that the gas supply piping has the capacity to meet the demand.

Finned copper tube gas boilers & water heaters – Boiler Manual

When applicable, provisions for vent, bleed and gas relief lines must be made in accordance with the latest revision of ANSI Z223.1/ NFPA 54.

Safe lighting and other performance criteria were met with the gas manifold and control assembly provided on the boiler. All gas connections MUST be leak tested before puing the boiler into operation.

Never use an open ame to test for gas leaks. Always

use an approved leak detection method. Failure to comply with this warning can cause extensive property damage, severe personal injury or death!

Whenever the gas supply piping is pressure tested the boiler/water heater gas controls must be protected. If the test pressure is equal to, or less than 1/2 psig, 3.5 kPa isolate the boiler/water heater by closing it’s manual shut o valve, see Figure 10. If the test pressure is greater than, or equal to 1/2 psig, 3.5 kPa, disconnect the boiler/ water heater and its individual shut-o valve.

Required Gas Pressure

Provide gas supply pressure at inlet to boiler gas train as follows:

LP Nat Minimum (in WC) 12 5

Maximum (in WC) 14 14

Measure pressure when boiler is ring at full rate. Low gas pressure could indicate undersized gas line or insucient gas supply.

"Static and operating gas pressure required at the gas valve inlet is between 5 in WC and 14 in WC for natural gas and 12 in WC and 14 in WC for propane. If the gas pressure is above this limit, a lock-up style regulator suitable for dead end service such as an Equimeter or Fisher must be installed to prevent increase (creep) of gas pressure when the units are not operating. is pressure regulator (supplied by others) may be installed at the service entrance to each unit or a "master" regulator sized to handle multiple units may be utilized. Consult local gas utility or regulator manufacturer for recommendations to meet specic job site requirements."

Gas appliances are rated based on sea level operation with no adjustment required at elevations up to 2000 , 610 m. At elevations above 2000 , 610 m, input ratings should be reduced by 4% for each additional 1000 , 305 m.

Check the input rate as follows:

1. Turn o all other gas appliances that use the same gas meter as the boiler/water heater.

2. Call your gas supplier and ask for the heating value of the gas.

3. Start the boiler/water heater and let it run for 15 minutes.

4. Using the gas meter and a stopwatch, clock the time that it takes to burn 10 

5. Insert the heating value and the time, in seconds, into the formula below.

6. Input = (heating value, Btu/hr)(3600)/(time, seconds)

7. If the computed rate deviates by more than 5% from the rated input value of the unit adjust the manifold pressure accordingly. DO NOT adjust the manifold pressure by more than 5%. If a proper rate cannot be maintained without adjusting the manifold pressure beyond the 5% limit, the main burner orices must be replaced. If the input rate is too low, go to the next larger size of main burner orices. If the input rate is too high, go to the next smaller size.

0.28m3 of gas and divide this time by 10.

Never increase the input to the boiler/water heater

above that for which it is rated. Doing so can cause premature failure of the unit!

e maximum inlet gas pressure listed on the rating

plate must not be exceeded or damage to the boiler/ water heater may occur!

e minimum supply pressure listed on the rating plate is for input adjustment.

NATUL GAS: Optimum results are obtained when the boiler/ water heater is operated at its full input rating, with 3.8into4.2in,

96.5 mm to 106.7 mm WC of manifold pressure. e manifold pressure should not vary outside this range. e gas valve pressure regulator has been preset at the factory. If adjustment is necessary the following steps must be followed:

1. Aach a 20 in, 508 mm WC manometer to the tap on the

manifold.

2. Remove the regulator adjustment screw cap from the gas regulator. On systems that do not use a separate gas regulator, remove the adjustment screw cap from the gas valve body on the valve closest to the gas supply piping.

3. Rotate the regulator adjustment screw clockwise to increase the manifold pressure, counterclockwise to decrease it.

4. Replace the regulator adjustment screw cap and manifold pressure tap plug.

Never force the regulator adjustment screw beyond

the stop limits or damage to the regulator will occur!

PROPANE GAS: A manifold pressure of 11 in, 279 mm WC must be maintained for proper operation of the boiler. If the manifold pressure is o by more than 5% adjust it according to steps 1 through

CONTROL DESCRIPTION

Low Water Cuto

If the boiler is to be installed above radiation or if required by other codes or regulations, install a low water cuto in appropriate piping.

If installed, ensure that the low water cuto device(s) function properly. Test in accordance with the manufacturer’s instructions included with the device(s).

Boiler Thermostat

If a thermostat is to be used to control the boiler always follow the instructions included with the thermostat. Proper location of the thermostat will ensure ecient trouble-free operation of the boiler. Mount the thermostat to an inside wall at a height approximately ve feet above the oor.

Avoid placing the thermostat in areas that will not provide an accurate measurement of the room temperature. Locating the thermostat behind a door, in an alcove, close to a source of thermal radiation or in a dray area will cause poor or sporadic heating.

For a thermostat that employs an adjustable heat anticipator, adjust the anticipator to match the current measured in the thermostat circuit. An increased anticipator seing may be necessary if the unit cycles frequently. If the room temperature over-shoots the thermostat seing, reduce the anticipator seing.

Finned copper tube gas boilers & water heaters – Boiler Manual

Operating Control

Per DOE mandate, the operating control incorporates an automatic means (thermal purge) of adjusting the boiler water temperature for hot water heating. e preferred control seing for potable hot water is 130°F, 54°C. e operating control should be set to the lowest seing that will satisfy the consumer's needs.

Seing the thermostat or operating control too high

can result in scalding resulting in severe personal injury!

Servicing , inspection and adjustment must be done by

a trained technician in accordance with all applicable local and national codes. Improper servicing or adjustment can damage the boiler/water heater!

e ceramic combustion chamber contains crystalline

silica. Wear a tightly ed dust mask when removing the burners or heat exchanger to prevent inhalation of airborn bers. Crystalline silica bers have been identied as carcinogenic, or possibly carcinogenic when inhaled.

High Limit (Aquastat)

e high limit is located in the top control area of the boiler/water heater. A remote capillary bulb is run to a well on the outlet side of the supply header.

e water heater high limit should be set a minimum of 20°F, 11°C higher than the operating control. Refer to the HOT WATER SUPPLY section for the proper supply water temperature.

Flow Switch

A ow switch is provided in the water outlet piping to prevent the boiler/water heater from ring without adequate water ow through the heat exchanger.

MAINTENANCE

Disconnect electrical power and close the manual gas

shut o valve before performing maintenance or severe personal injury may result!

Improper installation, adjustment, alteration, service

or maintenance can cause property damage, personal injury, exposure to hazardous materials or loss of life. Installation and service must be performed by a qualied installer, service agency or the gas supplier who must read and follow the supplied instructions before installing, ser vicing or removing this boiler. is boiler contains crystalline silica materials that have been identied as carcinogenic or possibly carcinogenic to humans when inhaled.

Use the “GENEL OPETION” and “CHECKING AND ADJUSTMENTS” sections of this manual for reference.

1. Check the thermostat or operating controls for proper operation.

2. A oat type low water cuto device must be ushed out per the manufacturers’ instructions. e probe on a probe low water cut o must be removed, cleaned and inspected at least once a year. Ensure that the low water cutos operate properly. If not, replace them.

3. e ow switch contacts must be open when water ow is not present.

4. e relief valve should not weep or discharge water at normal system pressure. If it does contact a qualied service technician to have it inspected. NEVER try to clean or repair the relief valve! If the valve fails to operate properly, have it replaced!

5. e aquastat high limit controls the maximum water temperature in the boiler. It should be set at least 20°F, 11°C above the operator set point. If the water temperature reaches the set temperature before the demand for heat has been met, the aquastat high limit should shut the boiler o. e water temperature should never exceed the maximum set 240°F, 116°C. e aquastat high limit cannot be repaired. If it fails to function properly, replace it.

6. Visually check the pilot and main burner ames to ensure proper operation, see Figures 11 & 13.

Yellow, oating ames indicate a lack of combustion

air. A liing ame indicates too much combustion air. Do not operate the boiler until the problem is solved or severe personal injury or death may occur!
