Cont Zone Control This can be also be set up using this control (see zone control wiring section for more detail) Minimum Firing Rate Setting Dip Switch #4 to ON will lock the unit into the minimum firing rate at all times. This is occasionally used for troubleshooting and gas pressure set up purposes. Move the switch back to OFF to allow the unit to modulate capacity. Maximum Firing Rate Setting Dip Switch #5 to ON will lock the unit into the maximum firing rate at all times.
Specific requirements for installation in Massachusetts In the Commonwealth of Massachusetts these units must be installed by a licensed gas fitter or plumber Venting : For the Quietside models DPW-099A, DPW-120A where the bottom of the vent termination and combustion air intake is installed at a height BELOW 4 ft above the grade level the following requirements must be satisfied 1.
Cont For the Quietside models listed above where the bottom of the vent termination and combustion air intake is installed at a height of 4ft ABOVE the grade level the 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 in the living area outside the bedroom(s). The Carbon Monoxide detector shall comply with NFPA 720 (2005 Edition) 2.
Specific requirements for installation in Canada The provinces of Ontario and Alberta have adopted standard ULC S636 requiring the following additional items to be noted. 1. Maximum flue temperature as tested is 136 DegF, allowing these units to be vented with Schedule 40 PVC under the regulation of ULC S636. 2.
Combustion and Leak Testing of DPW units As the front cover of the unit is mechanically attached and cannot be removed in operation without the use of a tool, it is not permissible to conduct combustion testing or leak testing of the unit with the front cover removed.
Zone control of DPW unit Zone control of the DPW unit is performed by a zero voltage or X-X contact from a relay or zone control panel closing when unit operation is required. The DPW unit should have two Brown low voltage wires connected into the microprocessor to facilitate this. It is possible depending on the production date of the unit, that these wires are supplied loose for field installation. If this is the case the following procedure should be followed to allow the units to be zoned. 1.
Cont 4. Switch Dip Switch # 3 to the ON position. 5. Simultaneously press both the Timer and Anti Freeze buttons on the controller for 5 seconds 6. The control will now enter the option set up mode, press the Timer button until 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.
Pump Curves – DPW Units The DPW units include a pump assembly that is used to provide the flow through the unit heat exchangers, and has a nominal flow of heating water for external piping arrangements. This pump is not designed to be the system pump providing flow to radiant loops or baseboard.
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 mounted adjacent to the DPW unit. It is connected to the DPW via the 2 Yellow wires and is powered by 20V DC.
