For the Quietside models listed above where the bottom of the vent terminationand combustion air intake is installed at a height of 4ft ABOVE the grade levelthe following requirements must be satisfied

1. If there is not one presently installed, on each floor level where there is a bedroom(s), a Carbon Monoxide detector and alarm shall be installed inthe living area outside the bedroom(s). The Carbon Monoxide detectorshall comply with NFPA 720 (2005 Edition)

2. A Carbon Monoxide detector shall be installed in the room where theODW unit is installed, the detector shall be :

a) Powered from the same power circuit that provides power for the ODWunit. A single electrical service switch shall be used to service both theunit and the detector

b) Have battery back up powerc) Meet ANSI/UL std 2034 and comply with NFPA 720 (2005 Edition)d) Approved and listed by a NRTL recognized under 527 CMR

3. A Quietside approved vent termination must be used. Installation of thevent termination must be in strict compliance with Quietside's writteninstructions, and a copy of these instructions must remain with the unitafter the installation is completed.

Vent Termination requirementsAs the DPW unit is a condensing product

The Vent for all Quietside DPW units shall not terminate

Over Public Walkways; or

Near soffit vents or crawl space vents or other area where condensate or vaporcould create a nuisance or hazard or cause property damage; or

Where condensate or vapor could cause damage or could be detrimental to theoperation of regulators, relief valves, or other equipment

Specific requirements for installation in Canada

The provinces of Ontario and Alberta have adopted standard ULC S636 requiringthe following additional items to be noted.

1. Maximum flue temperature as tested is 136 DegF, allowing theseunits to be vented with Schedule 40 PVC under the regulation ofULC S636.

2. Under the new requirements of ULC S636 regarding ventconnections to the unit, Quietside requires the Schedule 40 Ventpiping to be secured to the unit using approved PVC cement,following the cement manufacturers instructions regardingmethodology and curing time. A bead of high temperature siliconeshould be also run around the joint to ensure no leaks can occur.

5

Combustion and Leak Testing of DPW units

As the front cover of the unit is mechanically attached and cannot be removed inoperation without the use of a tool, it is not permissible to conduct combustiontesting or leak testing of the unit with the front cover removed.

Combustion testing must be achieved by using a calibrated combustion tester,with the probe inserted either in the flue exhaust of the vent termination or it ispermissible to take reading by accessing the flue pipe approximately 12" abovethe unit, providing adequate provisions are made for sealing any access aftertesting to ensure no leakage of flue gases into the occupied space.

Leak testing must take place with the end of the "sniffer probe" at least 1" fromany surface of the unit to ensure that false readings cannot be obtained.

Auto Fill - Closed Loop System

The DPW unit is fitted with a MANUAL Auto Fill valve, supplied in the closedposition.

The Fill Valve is not pressure regulated therefore care must be used whenopening the valve to prevent overfilling of the closed loop system and opening ofthe pressure relief valve.

Quietside recommends that the valve be left in the closed position and anexternal Boiler Feed Valve e.g. Taco 335/329 be installed in the piping system tomaintain an even pressure in the closed loop system

Manual Auto Fill Valve located on base of

6

cabinet.

Zone control of DPW unit

Zone control of the DPW unit is performed by a zero voltage or X-X contact froma relay or zone control panel closing when unit operation is required.

The DPW unit should have two Brown low voltage wires connected into themicroprocessor to facilitate this. It is possible depending on the production dateof the unit, that these wires are supplied loose for field installation. If this is thecase the following procedure should be followed to allow the units to be zoned.

1. Take wires provided and located the center electrical plug connection tothe microprocessor.

2. Insert wires into the empty slots located second from the bottom (aboveconnections with Yellow wires - see photo). Insert wire (electricalconnector end) into the empty slots, a click should be heard and the wireshould not pull loose.

3. With the two wires inserted into the microprocessor, power the unit onusing the DSR-100 controlller.

7

Cont

4. Switch Dip Switch # 3 to the ON position.

5. Simultaneously press both the Timer and Anti Freeze buttons on thecontroller for 5 seconds

6. The control will now enter the option set up mode, press the Timer buttonuntil the display in the top RH corner of the unit reads C6.

7. Press the Up Temperature key, to change the display from 2n to 3n

8. Press the unit On/Off button to turn off the control

9. Switch Dip Switch # 3 back to the OFF position

10. When the zone control wires are closed the unit will now operate andprovide closed loop heating water at the temperature set on the DSR-100

Anti-Freeze & Freeze Protection

For Anti Freeze protection in the Quietside units the following products arerecommended "No Burst"

"Fernox Alphii"

The maximum concentration allowed is 30% by volume which will protect the unitdown to approximately 5 DegF or -11 DegC

8

Pump Curves - DPW Units

The DPW units include a pump assembly that is used to provide the flow throughthe unit heat exchangers, and has a nominal flow of heating water for externalpiping arrangements.

This pump is not designed to be the system pump providing flow to radiant loopsor baseboard.

Therefore Quietside insists on using a Primary - Secondary pumpingarrangement, the recommended method uses the traditional large diameterPrimary loop

The main circulation pump or the zone pumps will then provide circulation intothe zones or the heating system

The only exception to this Primary - Secondary rule is for Air Handling units witha hot water coil where the Air Handling unit is located less than 10ft from theDPW unit.

9

Unit Controls & Zoning

A DSR-100F Controller is provided with the unit.

This is not used as a thermostat, but is a unit controller and should be mountedadjacent to the DPW unit. It is connected to the DPW via the 2 Yellow wires andis powered by 20V DC.

The DSR controller allows both the heating loop and DHW water temperatures tobe set

When the unit is started using the X - X or dry contacts on the microprocessor itwill operate and provide heating loop water at the set temperature until thezone(s) are satisfied. If a DHW call is experienced during heating operation theunit will automatically switch over to provide DHW.

DO NOT APPLY 24V AC OR LINE VOLTAGE TO THE X - X CONTACTSUNIT MICROPROCESSOR WILL FAIL IF IT RECEIVES 24V AC OR LINEVOLTAGE ON THESE CONTACTS

It is not permissible to power the secondary loop pump from the Primary looppump installed in the unit.Power for the Secondary loop pump should come from a switching relay e.gTaco SR501.
