GENERAL INFORMATION

1. GENERAL INFORMATION

1.1 General warnings

– Installation

Read all safety warnings in the

“Instruction Manual”. The additional safety issues outlined below must also be followed completely when installing this Boiler.

Use of a properly calibrated electronic combustion analyzer

MUST

be used when installing, servicing or converting this Boiler from Natural Gas to LP or from LP to Natural Gas.

Failure to remove or maintain the area free of combustible material, gasoline and other flammable liquids or vapors can result in severe personal injury, death or substantial property damage.

All applicable local, state, national and provincial codes, ordinances, regulations and laws must be observed.

For installations in Massachusetts

– code requires the units to be installed by a licensed plumbing or gas fitter.

If the hot water boiler is installed above radiation level or as required by the authority having jurisdiction, must be provided with a low water cutoff device at the time of boiler installation.

Where required by the authority having jurisdiction, the installation must conform to the Standard for controls and safety devices for automatically fired boilers, ANSI/ASME CSD1.

If an external electrical source is utilized, the appliance, when installed, must be electrically grounded in accordance with local codes or, in the absence of local codes, with the National Electrical Codes ANSI/NFPA 70 and or the CSA C22.1 Canadian Electrical Code.

Follow all local codes and/or the most recent edition of the National Fuel Gas Code (ANSI Z223.1/NFPA

54) in the USA or the Natural Gas and Propane Installation Code in Canada (CAN/CSA B149.1).

This unit is designed for indoor installations. DO NOT operate this unit without the vent piping connected.

Exhaust gases must be completely expelled out of the building.

Do not use this appliance if any part has been underwater. Immediately call a qualified service technician to inspect the appliance and replace any part of the control system and any gas control which has been underwater.

Be sure not to reverse the water and gas connections as this may damage the gas valves.

Water temperatures over 125 ° F can cause severe burns instantly or death from scalding. If the proposed boiler outlet temperature is above 125

°

F, a thermostatically controlled mixing valve (or a temperature limiting valve) for reducing point of use water temperature is recommended to reduce the risk of scald injury. Contact a licensed plumber or the local plumbing authority for further information.

The appliance should be located in an area where leakage within the unit or at its connections will not result in damage to the area adjacent to the appliance or to lower floors of the structure. PENSOTTI will not be responsible for any damage resulting from leaking if adequate drainage is not provided. When such locations cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed under the appliance.

The flow of ventilation to the b o i l e r must not be obstructed. The b o i l e r area must be kept clear and free from combustible materials, gasoline and other flammable vapors and liquids.

If the water quality is known to be highly acidic and/or extremely hard, water treatments (ie water softeners and filtration) are recommended to maintain full warranty. Consult the local water authority.

DO NOT over-tighten fittings, as pipe and/or fitting damage may occur causing leakage.

DO NOT install boiler where subject to vibrations.

For other than a direct vent appliance, the appliance must be located as close as possible to a chimney or gas vent.

Should overheating occur or the gas supply fails to shut off, turn the manual gas control valve to the appliance. Contact a Service Technician immediately.

1


Clearance must be in accordance with the local installation codes and the requirements of the gas supplier.

Never operate the heater unless it is vented to the outdoors and has adequate air supply to avoid risks of improper operation, fire, explosion or asphyxiation.

DO NOT install this boiler directly on a carpeted floor. A fire hazard may result. The boiler shall be installed on a metal or wood panel extending beyond the full width and depth of the boiler by at least 3 inches (76.2mm) in any direction or, if the boiler is installed in an alcove or closet, the entire floor shall be covered by the panel.

For safe operation, an ample supply of air must be provided for proper combustion and ventilation in accordance with the National Fuel Gas Code ANSI Z223.1/NFPA 54 National Fuel Gas Code CSA/B149.1

Natural Gas and Propane Installation Codes or applicable provisions of the local building codes. An insufficient supply of air may result in a yellow, luminous burner flame, carboning or sooting of the heat exchanger, or create a risk of asphyxiation. Do not obstruct the flow of combustion and ventilation air.

This unit is not intended to operate at gas supply pressures other than those shown on the rating plate. Exposure to higher gas supply pressure may cause damage to gas valves, which can result in fire or explosion. If over- pressure has occurred, such as through improper testing of gas lines or emergency malfunction of the supply system, the gas valves must be checked for safe operation.

A thermostatic mixing valve must be added to this system to prevent scalding, if regulated by local codes and authorities.

Check the Rating Plate

PENSOTTI units come from the factory configured for use with either LP or Natural Gas. Prior to installation, check the rating plate of the boiler to ensure the unit matches gas type, gas pressure, water pressure and electrical supply. If the unit does not match the requirements, do not install.

Be sure the gas type and electricity voltage match the rating plate.

There is a risk in using fuel burning appliances in rooms or areas where gasoline, other flammable liquids or engine-driven equipment or vehicles are stored, operated or are repaired. Flammable vapors are heavy and travel along the floor and may be ignited by the igniter or main burner flames causing fire or explosion. Some local codes permit operation of gas appliances if installed 18 inches or more above the floor. This may reduce the risk if location in such an area cannot be avoided. Flammable items, pressurized containers or any other potential fire hazardous articles must never be placed on or adjacent to the boiler. Open containers of flammable materials should not be stored or used in the same room with the boiler.

Do not install the PENSOTTI boiler in areas with excessive high humidity.

Do not install the unit in location where there is excessive humidity, such as a bathroom, damp crawl space, and other areas with high levels of humidity. This may cause the unit to malfunction.

To avoid possible electrical shock, DO NOT touch the internal components of the boiler or the power cord with wet hands .

DO NOT splash excessive water on the boiler when cleaning, as they are water resistant, not water proof.

Professionally qualified personnel in accordance with current laws and standards and in line with the manufacturer

’s instructions must install the appliance.

The commissioning of the boiler and any subsequent work carried out on the appliance must be effected by an appropriately qualified technician.

The appliance must be used solely for the purpose for which it has been designed and manufactured: central heating and domestic hot water production. Any other use is deemed as improper and as such dangerous.

Under no circumstances will the manufacturer be held responsible for damage or injury to persons or animals caused by errors in the installation and/or use of the appliance, or through non-compliance with current local and national standards and/or the manufacturer

Isolation Valves must be installed on the heating and D.H.W circuits. This will facilitate all maintenance and service operations when the appliance needs to be drained.



To prevent vibration and noise coming from the system, do not use pipes of reduced diameter, short radius elbows or severe reductions in the cross sections of the water passages.



In order to guarantee the reliability of the boiler a pressure reducing valve and backflow preventer must be installed.



To facilitate the installation, the boiler is supplied with a hydraulic connection kit (see fig.2).

A pressure relief valve is installed in this dual purpose boiler that is rated in accordance with and complying with either

The Standard for relief Valves and Automatic Shutoff Devices for Hot Water Supply Systems, AINSI Z21.22 or The

ANSI/ASME Boiler and Pressure Vessel Code, Section IV (Heating Boilers).The relief valve must be installed such that the discharge will be conducted to a suitable place for disposal when relief occurs. The discharge line must be installed to allow complete drainage of both the valve and the line. If this unit is installed with a separate storage vessel, the separate vessel must have its own temperature and pressure relief valve. This valve must also comply with The

Standard for Relief Valves and Automatic Shutoff Devices for Hot Water Supply Systems. AINSI Z21.22 (in the U.S. only). A temperature relief valve is not required but if one is used, do not install the valve with the probe directly in the flow of water. This may cause unwarranted discharge of the valve.

Follow the electrical code requirements of the local authority having jurisdiction. In the absence of such requirements, follow the latest edition of the National Electrical Code (NFPA 70) in the U.S. or the latest edition of CGA C22.1 Canadian Electrical Code

– Part 1 in Canada.

3.7.2 Electric Wiring: Ground and Surges

All units come with factory installed 3-pronged (grounded) plug end. The boiler must be plugged into a dedicated electrical outlet and circuit. The use of extension cords are prohibited.

If the local jurisdiction requires the unit to be wired directly, remove and discard the factory installed plug. An

ON/OFF switch controlling the main power between the breaker and the Boiler should be provided to facilitate end-user maintenance and servicing. This should be done by a qualified electrician.

The boiler must be electrically grounded. Ensure the electrical receptacle, in which the boiler will be plugged into, is properly grounded; if wiring directly, do not attach the ground wire to either the gas or the water piping as plastic pipe or dielectric unions may isolate the boiler electrically.

The use of a surge protector, surge capacitor, line conditioner or equivalent is recommended to protect the appliance from power surges.

If a generator is to be used as “backup” power a line conditioner

must

be installed to protect the appliance from erratic voltage and Hz.

If the boiler is to be installed in a structure utilizing a emergency stand-by generator, the installation of a surge capacitor, surge protector, line conditioner or equivalent is required.

If the boiler is to be installed in a structure where frequent power outages are experienced the installation of a surge capacitor, surge protector, line conditioner or equivalent is required.

Do not energize electric power to the unit until all plumbing and gas piping is complete and the boiler has been filled with water and all air has been properly purged for the boiler and heating system.

The electrical supply required by the boiler is 120VAC at 60Hz with a maximum 4A rating with proper grounding. Protection must be in place to prevent the Boiler from being exposed to voltage in excess of

130VAC Max or 95VAC Min.

Damage caused by excessive voltage is not covered under warranty.

DO NOT connect 220-240VAC to this PENSOTTI Boiler. This will damage the boiler and void the warranty.

Do not disconnect the power supply when the unit is in normal operation.

If there is a power failure in cold weather areas, the freeze prevention system in the boiler will not operate and may result in freezing of the heat exchanger; in cold weather areas where power failures are common, you must completely drain the unit to prevent damage if the power will be off for any extended period of time.

Damage caused by freezing is not covered under warranty.

CAUTION : Label all wires prior to disconnection when servicing controls. W iring errors can cause improper and dangerous operation. Verify proper operation after servicing.

The connection to the main power supply must be carried out by professionally qualified electrical personnel, registered in accordance with current legislation and local authorities.

27


Always check to make sure that the appliance has an efficient earth ground system. This requirement is only satisfied if it has been properly connected to an efficient ground system installed in accordance with the requirements of current safety standards and carried out by professionally qualified personnel.

This basic safety measure must be checked, verified and carried out by professionally qualified personnel. Have the electrical system checked by a qualified electrician. The manufacturer will not be held liable for any damage or injury caused as a result of an inefficient or faulty earth ground system.

■ Ensure the domestic power supply is checked by a qualified electrician to ensure that it can support the maximum power absorption of the appliance, as indicated on the rating plate. In particular, make sure that the cable sizes are adequate for the power absorbed by the appliance;

■ The power supply cable must be replaced by a qualified electrician. If the cable is damaged in any way, switch off the appliance and have the cable replaced by a suitably qualified electrician;

When using an electrical appliance, a few fundamental rules must be observed:

Do not touch the appliance with damp or wet parts of the body or when barefoot.

Do not pull on the electric wires.

Do not allow the appliance to be used by children or anyone unfamiliar with its operation;

If the unit fails to re-start after any fault and you have already pressed the reset “R” button, unplug the unit for 30 seconds, then re-plug in the unit and try to restart with the on/off switch.

If the unit fails to restart, call a qualified Technician for service. DO NOT ATTEMPT ANY

REPAIRS ON YOUR OWN.

Before connecting the venting system to the boiler, be sure to install the correct

Flue Diaphragm into the boiler exhaust outlet. (see section 3.10 on page 45).

APPLICATIONS

M&G DuraVent’s Concentric Stainless (CVS) vent pipe is listed to UL1738 as a double-wall vent system for Category II, III, and IV gas

Appliances.

CVS is pressure rated to 10 in-w.c. for the inner pipe.

CVS can also be used as a direct vent system, where the inner pipe is the exhaust vent; the outer pipe supplies the combustion air for the appliance. When installing CVS with direct vent appliances, the vent is considered a component of the appliance, and is listed in conjunction with the appliance to the corresponding appliance standard. Check with your appliance manufacturer or look in the appliance installation instructions to verify that

M&G DuraVent’s CVS has been listed as a direct vent for use with your appliance.

CLEARANCES

CVS is listed to 0" clearance as a doublewall vent system for Category II, III, and IV appliances, for flue temperature of up to

400-degrees F for horizontal enclosures, and up to 480-degrees F for vertical enclosures.

When CVS is used as a concentric/direct vent system on gas and installed on a Pensotti Solenne

CLASSIC boiler,

clearance to combustibles is 0” .

Never fill any required clearance space with insulation or any other materials. Combustible materials include, but are not limited to, lumber, plywood, sheetrock, plaster and lath, furniture, curtains, electrical wiring, and building insulation.

PERMITS

Before installation, check with your local

Building Official, Fire Official, or other authority having jurisdiction regarding permits, restrictions, and installation inspections in your area.

GENERAL INSTALLATION NOTES

Read through these installation instructions before beginning your installation. Proper planning for your Concentric Stainless Vent system installation will result in greater safety, efficiency, and convenience, as well as saving time and money. You must use only authorized M&G DuraVent parts, or other parts specifically authorized and listed by the appliance manufacturer in order to maintain a safe, approved system. Do not mix parts or try to match with other products or use improvised solutions. Do not install damaged or modified parts. Practice good workmanship. Sloppy work could jeopardize your vent’s safety. Keep electrical wiring and building insulation away from all chimneys and vents. When deciding the location of your installation, try to avoid modifications to structural components of the building. If you have any questions, contact either your dealer or M&G DuraVent directly.

Check with the appliance manufacturer for the maximum and minimum allowed vent runs for your specific appliance model, including maximum number elbows allowed in the system. The total vent length from the appliance to the termination shall not be greater than what is specified by the appliance manufacturer. For condensing appliances, always follow the appliance manufacturer’s recommendation for handling condensate drainage.

30


Plan the layout of the vent system:

• Consider the length of horizontal runs, elbows, clearance requirements, and location of terminations.

• For horizontal vent runs, maintain at least a ¼” rise per foot away from the appliance to prevent collection of condensate or buildup of heat in the vent.

• Consider condensate drainage, if needed for your appliance. Refer to the appliance manufacturer’s installation instructions for requirements of condensate drainage.

• The CVS system must not be routed into, through, or within any other vent or chimney, with the exception of running the vent through an otherwise unused masonry chimney.

• The vent system must terminate in accordance with local code requirements and appropriate National Codes: o For the US (Gas): NFPA 54 / ANSI Z223.1

National Fuel Gas Code or the International

Fuel Gas Code o For the US (Pellet): NFPA 211 Standard for

Chimneys, Fireplaces, Vents, and Solid Fuel

Determine the venting path required for your installation. There are two general types of installations: Horizontal Installations, and

Vertical Installations.

Refer to

Figure 2

for some typical installations.


(d) Clearance to an unventilated soffit:

24 inches minimum

.

(e) Clearance to an outside corner:

(f) Clearance to an inside corner:



(g) Not to be installed above a meter/regulator

Always check with the appliance manufacturer for requirements or restrictions with the venting. To determine the installed length of vent pipe, subtract 1-

1/4” for each joint due to the joint overlap. assembly within

4 feet

horizontally from the centerline of the regulator.

(h) Clearance to a gas service regulator vent outlet: 6 feet minimum.

(i) Clearance to non-mechanical air supply inlet to a building or the combustion air inlet to any

Horizontal Installations

1. Install Appliance.

Determine where your appliance will be installed and follow t he Appliance manufacturer’s installation instructions accordingly. other appliance: 12 inches minimum (US), 6 ft

(Canada)

(j) Clearance to a mechanical air supply inlet: 6 feet minimum.

(k) Clearance above a paved sidewalk or paved driveway located on public property:

7 feet minimum

and/or refer to local code.

2. Determine location of wall penetration.

Identify where you want the vent to penetrate through the wall to the outside. Consider the

(l) Terminate above the snowline for the area. restrictions and requirements for the location of the Horizontal Vent Cap, listed below.

When determining the location of the wall penetration, be sure to account for the height of the Appliance Adapter (if needed) and the radius/height of the Elbow. For horizontal vent runs, always maintain at least a ¼” rise per foot away from the appliance

(Fig 3)

to prevent collection of condensate or buildup of heat in the vent. Also make sure you have accommodated any minimum vent height, if any, that the appliance manufacturer may require.

The Horizontal Termination Cap must meet the following requirements:

(a) Clearance above the ground, veranda, porch, deck, balcony and anticpated snow level:

12 inches minimum.

(b) Clearance to a window (operable or fixed closed) or door:


.

(c) Vertical clearance to a ventilated soffit located above the Termination Cap (if soffit extends a horizontal distance of

2 feet out over

the centerline of the termination):


.

33


3. Cut wall penetration.

Refer to the appliance manufacturer for clearance to combustible requirements from the vent. To accommodate the flared end of the vent pipe, the minimum hole size should be 5-

3/8” x

5-

3/8” for a square cut, or 5-3/8” diameter for a round cut

(Fig 5)

. Always check with the appliance manufacturer for any additional clearance to combustibles (if any) from the venting that may be required. For reference, the Outside Trim Ring provided with the

Horizontal Termination Cap measures a maximum of 8-

1/2” diameter, and has a hole pattern of 7” diameter. For pellet fuel installs, a wall thimble is required.

4. Layout the Vent.

Verify which CVS vent lengths and components you will need for your installation. Note that the Horizontal

Termination Cap must fit at a

minimum 6 inch

distance outside of the exterior wall

(Figs

3 & 4)

. This distance is needed to ensure proper airflow and pressure within the CVS vent system. To ensure this distance, the

Horizontal Termination Cap is adjustable. Also,

Telescoping Adjustable lengths are available.

5. Install Vent.

Once the vent path and components have been determined, install the vent. Align the male and female pipe ends as described in the Joint Connection section, push together and twist lock

(Fig 2)

. Note the direction of the pipe is important. The outer wall female end must face downward/towards the appliance; and the outer wall male end must face upward/away from the appliance.

The direction is to ensure correct condensate drainage and weatherization.

If Telescoping Adjustables are used, secure them at the desired length by using (3) ½” screws provided.

6. Support Vent.

Wall Straps are required every 8-ft of horizontal run in order to properly support the vent system

(Fig 3)

. If the installation extends through the wall in less than 8-ft of vent pipe, a wall strap is not required. Wall Straps are designed to provide a 1” standoff from nearby walls or ceilings. Use

(2) 1-

1/2” wood screws to secure each Wall

Strap.

7. Install Wall Termination.

If the optional

Interior Trim Ring will be installed, bend the three tabs and slip the ring onto the pipe section previous to the Horizontal Termination

Cap. Adjust the length of the Horizontal

Termination Cap so that the inside edge of the bead of the black-painted exterior portion is flush with the outer wall. This bead is used in combination with the Outer Trim Ring (supplied with the cap) to hold the cap in place at the wall. Once the Horizontal Termination Cap has been adjusted to the correct length, secure it in place with (3) ½” sheet metal screws

(Fig 5)

.

Then twist-lock on the Horizontal Termination

Cap, and align the cap so the air inlet openings are downward

(Figs 3 & 4)

.

Install the Outer Trim Ring over the Horizontal Termination Cap and secure in place with the (3) 1-

1/2” wood screws

(Fig 5)

.

Seal the Outer Trim Ring against the exterior wall using weatherizing silicone sealant.

If the Interior Trim Ring is installed, slide the

Trim Ring against the interior wall and secure in place with (3) 1-

1/2” wood screws. Secure the Interior Trim Ring to the CVS pipe by using

(3) ½” sheet metal screws through the tabs in the Trim Ring. Be sure you do not drill through the gasket in the outer wall of the CVS vent pipe.

34


Vertical Installation:

If the vent pipe is to pass through a cold attic space. Vent pipe MUST be insulated with the proper insulation material.

1. Install Appliance.

Determine where your appliance will be installed and follow the Appliance manufacturer’s installation instructions accordingly.

2. Determine the location of your ceiling and/or roof penetration.

Avoid cutting floor or roof supporting members. Always make sure to follow the appliance manufacturer’s required minimum clearance to combustibles.

3. Cut and frame floor penetration openings.

Cut and frame 7-

1/2” x 7-1/2” openings at each floor level through which the CVS vent system will penetrate. The opening at the roof does not require framing.

Vertical installations of the CVS vent need to be supported. A Firestop Support is required where the vent system passes through the first floor, and additional Firestops are required at each floor opening, except the roof. Follow the appliance manufacturer’s requirements for minimum clearance to combustibles

4. Install Firestop Support(s).

At each framed floor opening, install a Firestop Support. The

Firestop Support is listed to support up to 40-ft of CVS vent pipe. The Firestop Support is installed from underneath the opening, held in place by (4) 1-

1/2” wood screws in the corners

(Fig 6). From the other side, extend the straps of the Firestop Support and secure them to nearby framing members with additional 1-

1/2” wood screws. As the vent passes through the

Firestop Support, install the clamp around the vent and tighten withthe screws provided, so the weight of the vent is supported by the

Firestop Support

(Fig 6)

.

35


5. Install CVS Vent Pipe.

If your appliance requires an Appliance Adapter, install it onto the appliance. Twist-lock on the first section of CVS vent pipe and continue to add vent pipe sections for your installation. As the vent passes through Firestop Supports, tighten the supporting clamp around the vent pipe.

Any elbow offsets must be supported by Wall

Straps. Wall Straps must be used to support any horizontal or inclined sections longer than

8-ft. Plumbers tape is allowed to be used to support the vent pipe for interior offsets only, if nearby walls/ceilings/framing members are not close enough to use the Wall Straps. As the CVS vent passes through the roof, install a Roof Support at the roof level to hold the vent in place, if there are no Wall

Straps within 8-ft

(Fig 7)

. The Roof Support is clamped around the vent pipe and is secured to the topside or underside of the roof with at least (4) nails or wood screws.

6. Enclosures.

Check with your local authority for enclosure requirements when penetrating a vent through an occupied area. Except for the installation in one and two family dwellings, a venting system that extends through any zone above where the connected appliance is located shall have an enclosure with a fire resistance rating equal or greater than that of the floor or roof assembly through which it passes.

For exterior mounted systems, it is recommended that the vent system be enclosed below the roofline to limit condensation and protect against possible incidental damage that may occur to the vent pipe.

7. Install Flashing and Vertical Termination.

Install enough vent pipe through the roof penetration to allow the Adjustable Flashing to fit over the pipe. The Adjustable Flashing will fit roofs from 0/12-12/12 pitch. Slide the Flashing over the vent pipe and secure to the roof.

The upper edge of the flashing should slide under the uphill shingles/roofing material, if applicable. Use appropriate roofing sealant to weatherize the flashing to the roof, and secure the flashing in place using at least (4) roofing nails/screws per side of the flashing

(Fig 7

).

After the Flashing is installed, wrap the Storm

Collar around the vent pipe, inserting the tab and folding it back to secure the collar tightly against the pipe. A sheet metal screw may be used to secure the tab in place. Slide the

Storm Collar down on top of the Flashing. Use a bead of sealant where the Storm Collar sits on the Flashing to prevent any rain infiltration.

The vent pipe must extend above the roof a minimum of 12”, but the installation must also meet any additional height requirements as specified in the appliance manufacturer’s installation instructions. Once the required vent height has been reached, twist-lock the

Vertical Termination Cap onto the top section of CVS vent pipe to complete the Vertical

Installation

(Fig 7)

. If more than 4 feet of CVS extends above the roof, then the vent pipe will need to be supported.

36


MAINTENANCE

Conduct an inspection of the venting system semiannually. Recommended areas to inspect are as follows:

1. Check areas of the Venting System which are exposed to the elements for corrosion.

These will appear as rust spots or streaks, and in extreme cases, holes. These components should immediately be replaced.

2. Remove the Termination Cap, and shine a flashlight down the Vent.

Clean and remove any deposited or foreign material.

3. Check for evidence of excessive condensation, such as water droplets forming in the inner liner, and subsequently dripping out at joints.

Continuous condensate can cause corrosion of caps, pipe, and fittings. It may be caused by having excessive lateral runs, too many elbows, and exterior portions of the system being exposed to cold weather.

4. Inspect joints, to verify that no Pipe

Sections or Fittings have been disturbed, and consequently loosened.

Also check mechanical supports such as Wall Straps, or plumbers' tape for rigidity.

4. COMMISSIONING THE APPLIANCE

4.1 General warnings

The following operations must be carried out by professionally qualified personnel, registered in accordance with current legislation.

Use of a properly calibrated electronic combustion analyzer MUST be used when installing, servicing or converting this Boiler from Natural Gas to LP or from LP to Natural Gas.

The boiler leaves the factory pre-set and tested for burning either Natural Gas or LPG. Nevertheless, when starting the boiler for the first time, make sure that the information on the rating plate corresponds to the type of gas being supplied to the boiler.

Once the system has been filled and the necessary adjustments made, remember to tighten the screws of the gas valve test point and make sure that there are no gas leaks from the test point or from any gas pipe fittings within the boiler.

■

Preliminary operations

Switching the boiler on for the first time means checking that the installation, regulation and operation of the appliance are correct:

Check that the rating on the rating plate corresponds to that of the main supply networks (gas, electricity, water);

Check that the power supply voltage to the boiler complies with the rating plate (120 V

– 60 Hz) and that the live, neutral and earth ground wires are connected properly. Also make sure that the earth ground connection is sound;

Check that the gas supply line is correctly sized for the flow rate required by the boiler and that it is fitted with all the safety and control devices stipulated by current regulations;

Check that the supply of combustion air is functioning correctly and in line with current law and national and local standards;

Check for the presence of permanent aeration/ventilation openings as required by current law for the type of appliances installed;

Check that the exhaust vent and its connections to the termination comply with the requirements of current law and national and local standards for the type of appliances installed;

Check that all venting is installed, supported and secured as per the vent manufactures instructions;

Make sure that any central heating shut-off valves are open;

Check that there are no flammable materials or liquids in the immediate vicinity of the boiler.

Flush out both primary and domestic hot water circuits (see 4.3

“Flushing the system”).

47

4.2 Filling the system


Use only clean tap water to fill the system.

Once the water pipes have been connected, close the gas feed valve and fill the system as follows:



Check that the circulation pump runs freely by removing the “PUMP PLUG” and manual spinning the rotor using a small slotted screwdriver.



Check that the cap of the air vent valve has been loosened slightly to allow air to escape from the system (fig.1).



Open the filling tap

R

(fig. 2) or utilizing an external pressure reducing valve and backflow preventer, use the pressure gauge

M

(fig.2) to check that the systems pressure reaches the middle of the green area (equal to 14.5 psi , see fig. 3).



On completion, make sure that the filling tap

R is closed.



Once again unscrew the plug on the pump to remove any trapped air, check that the pump is free then re-tighten it when water starts to flow out.



Properly purge the heating systems of all air.



If, after the above operations, there is a reduction in the pressure refill this systems as directed above.



Pensotti recommends the installation of an automatic pressure reducing valve with backflow preventer installed in the proper location within the heating system. Adjust it to maintain a minimum water pressure of 14.5 psi or as required by the heating system design.

4.3 Flushing the system

Failure to flush and add inhibitor to the system will invalidate the appliance warranty.

All systems must be thoroughly drained and flushed using additives

– corrosion inhibitors and flushing agents/descalers. Pensotti requires the use of the supplied Fernox Commissioning Kit or individual containers of Fernox F3 or F5 cleaner and F1 protector. Follow Fernox installation instructions. Failure to use Fernox F3 or F5 cleaner and F1 protector will void the warranty for all waterside components.

To flush out the primary side of this unit a.

Fill the boiler as per the filling instructions.

b.

Using a drain off cock on the lowest point of the system allow the water to drain from the system and boiler.

c.

In order to flush the system correctly turn off all radiators open the filling loop and drain cock simultaneously and allow the water to flow through the boiler.

d.

Open each individual radiator allowing water to flow through then turn that radiator off and repeat for all radiators on the system.

e.

Turn off the filling loop and close the drain cock open all radiators and open the filling to fill the system.

f.

Continue to fill the system until the pressure gauge reads in the Green section of the gauge (14.5 psi).

To flush out domestic hot water circuit a.

Open all hot water outlets.

b.

Turn on inlet group supply so water enters the boiler; leave to fill until water is released from the hot water outlets.

Turn off all hot water outlets.

c.

The jets must be fitted with new gaskets;

5.

reassemble the entire burner unit. Use the soapy water method to check for gas leaks each time gas connections are dismantled and reassembled;

6.

select the new gas type by changing parameter

P01

(see

‘Parameters table’ 5.1

);

7.

to convert the appliance from L.P.G. to Natural Gas proceed with the min. and max. gas pressure adjustment (see

‘

■ Check that the combustion is correctly regulated and if necessary make adjustments according to section 4.4 “Starting the boiler”.

Fig 1.

Fig 2.

■ Check all heating safety systems. Ex; termpeature saeftly limit, air pressure switch, flame failure, etc.

65


6.3 Accessing the boiler

All maintenance operations require one or more of the boiler casing panels to be removed.

The side panels can only be removed after the front panel has been removed.

Front panel:



Remove the fixing screws at the lower edge of the front panel.



Grasp the lower part of the panel and pull it outwards (see fig. 1) and then up (see fig. 2).

Left and right side panel:



Remove the fixing screws at the front and lower edge of the side panel to remove.



Grasp the bottom of the panel, move it sideways and then upwards to remove it.

To access the electrical connections of the control panel, proceed as follows:



Draining the domestic hot water system

If there is a danger of freezing, the domestic hot water system should be drained. This can be done as follows:



Close the main water supply valve.



Open all the hot and cold water taps.



Drain the water from the system. Used compressed air to evacuate the pipes of any remaining water.



Use non-toxic antifreeze to protect the DHW system.



On completion, close all the previously opened taps.

Freeze Protection

Glycol must not be used in Domestic Hot Water applications.

System winterization (non-operative system)

Because it may be impossible to completely drain the boilers heating circuit, D.H.W circuit and distribution system.

Pensotti recommends the introduction of the proper type antifreeze to protect these systems from freezing damage.

System winterization (operating system)

Pensotti boilers are certified for indoor use ONLY. Proper precautions for freeze protection are recommended for boilers and associated piping in areas where the danger of freezing exists. Do not use automotive antifreeze. Pensotti recommends the use of inhibited glycol concentrations between 20-35% glycol. Glycol products must be maintained properly so they do not become inactive or corrosive, consult glycol specifications for more information.
