Universal Control w. variable speed & PDS

In gas-fired fireplaces, modulation may not always be required. In this case, an ENERVEX Fan and Damper Control (ADC 100) is a great choice.

This fan controller may be interlocked with the fireplace to control the speed of the fan and maintain proper draft in the chimney. It provides a 10-120 VAC signal to single-phase fans and a 0-10 VDC signal that can be interpreted to control three-phase fans by an EDrive.

The ENERVEX ADC100 Appliance Draft Control is used to control drafts in systems where modulation is not required. It controls the speed of the fan to maintain proper pressure in the chimney. The ADC100 is for indoor installations only. The control can be used with Models RS and GSV Fans. The ADC100 is typically used to control the draft of a gas-fired furnace, fireplace, stove, or pizza oven.

The ADC100 comes with an external PDS. The PDS is a NO/NC switch that monitors the pressure in the chimney. The ADC100 operates a chimney fan at a set speed to create and maintain a proper mechanical draft at the outlet of a heating appliance(s). The control provides a 10-120 VAC signal to single-phase fans, as well as a 0-10 VDC signal that can be used to control 3-phase fans by a variable frequency drive. The ADC100 comes with an external PDS. The PDS is a NO/ NC switch that monitors the pressure in the chimney. In case of inadequate draft, the PDS will open and if open for 15 seconds, the control will go into alarm mode and lockout the appliance until the draft is restored. The control features a manual and automatic adjustment mode which is selected via dipswitch. The PDS check function and manual or automatic reset function are also selected through a dipswitch. An integrated damper relay allows a damper to be connected directly to the ADC100. The control ensures that the damper is fully open before allowing the appliance to operate by interlocking the damper end-switches to the control. In the event that the controller senses any mechanical failures, the control will initiate a retry sequence

Material. The enclosure is made of NEMA 1 rated ABS plastic.

    • Researched and ordered my fireplace from US FIreplace Store. Pricing was a fair value however, the customer service was EXCELLENT! I had an issue with the direct vent venting. I called US Fireplace and the correct items were sent out the next day AND Janessa stayed on top of my return authorization and sent me the permissions and documents I needed to return the incorrect item and no cost to me, including return shipping. Overall, I am a very satisfied customer and my fireplace looks and operates flawlessly. I am glad that I selected US FIreplace to source my direct vent fireplace. Thank you for the great service.

    • I had placed an order, through Lowe's Home Improvement, for an Electric Firebox: Revillusion RBF42. Ordered 1st part of January. Was told I would have it in 3 weeks. When checking to see is it came in, was told it was delayed to 3/15. Was then told is was delayed until 4/25. Waited until 4/27 to check on it. Was then told it was now delayed until August. This firebox was going in a new Sun Room addition. I could not get my final inspection until the Firebox was installed. I went on line and googled for this same product. US Fireplace Store web site was given to me. This was on a Saturday. I call and reached a very nice man. Explain what I was look for. He checked and told me they had 30 of them in stock. I almost fell out of my chair. I clarified with him the product I was wanting. I ask how soon could I get it. He told me it would ship today. Again, was amazed. It arrived on the following Monday. What a pleasure and a relief working with US Fireplace Store and their employees. Exceed my expectations.

    • Great prices, quick delivery and fast hassle free services on the issue I encountered. I had purchased an electric fireplace unit that would not fit into the existing fireplace space. With one email I was able to get the wrong fireplace refunded and picked up at my home at no extra cost and the new one I purchased and delivered free of charge. Great company.
