Cont Zone Control This can be also be set up using this control (see zone control wiring section for more detail) Maximum Firing Rate Setting Dip Switch #4 to ON will lock the unit into the maximum 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 Minimum Firing Rate Setting Dip Switch #5 to ON will lock the unit into the minimum 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. You will find two brown wires attached to the upper Molex connector of the main PC board. These wires can be extended with 18 gauge thermostat wire and only connected to dry contacts from your zone control panel end switch. See example wire diagrams on the last four pages of this manual.
Anti Freeze & Freeze Protection For Anti Freeze protection in the Quietside units the following products are recommended “No Burst” “Fernox Alphii” The maximum concentration allowed is 30% by volume which will protect the unit down to approximately 5 DegF or -11 DegC Water Quality DPW models potable side must have the water quality within the following limits for long life and reliable operation. The water supply should be tested to make sure the quality is within specified limits.
Pump Curves & Primary – Secondary Piping 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.
