flex duct gives added install flexibility

By Linkysys

Comments about 50 Gallon ProMax Direct Vent Residential Water Heater:

So far so good. AO Smith has an excellent reputation and only time will tell how long this unit lasts. My previous heaters were over 20 years old. I like the flex duct design as it allows for more flexibility than the rigid vent of my previous unit. I was trying to match an existing hole and the dimensions of the water heaters have changed due to higher tank insulation standards. Having the flex duct meant not needing to cut another 7" hole in my wall. The piezo valve is nice and it shows you that it is running with a blinking led (no electricity required). This type of water heater is one of the few that can be vented directly through a wall and requires no electricity to run. If you have outages, these heaters are a must.

Please be advised that this unit has a plastic air tube that is exterior to the tank and runs up the back. This makes it quite challenging to strap the tank per code to the wall as you must shim it around the plastic tube. That's the hardest part of the install IMHO is figuring out how to shim it away from the wall to leave a gap for the tube and still have it snug enough to pass code in earthquake country.

Pay attention to the instructions. I read one review by a person who was concerned about heat from the exhaust duct. My guess is that s/he failed to add the restrictor plate which is necessary for shorter vents.

I found the portion of the duct which has the O-rings to be very difficult to seat. I put all of my weight on it and still could not get it to slide far enough for the spring clip to lock in the groove on the collar. I noticed it had a very slight amount of grease. I had some high temp silicone brake grease that I applied to the mating surfaces and it made them go together much easier.

I have two quibbles with the manufacturer. First, as this is among the most expensive tank models of this type it should carry their longer 10 year warranty and not the miserly 6 year. Second, the packing leaves no space between the thin sheet metal and the box. Any slight impact to the box and the heater will arrive looking like scratch and dent merchandise. If you make a quality product, and undoubtedly AO Smith does, why not provide comparable packaging?

Nice Unit - Delivered to Door

By BoilerMakerBob

from Indianapolis

Verified Buyer

Comments about 50 Gallon ProMax Direct Vent Residential Water Heater:

I bought this unit to replace a State Industries direct vent that was leaking after 12 years. Reviews seemed to indicate a relatively short life for the State WH, so I decided to try the AO Smith DV50.
Delivery Delivery was to my driveway and was easy, accurate (they were there when they said) and the unit was in excellent condition. Installation (done by me) was straightforward and the manual was well written and the illustrations good. I reused the State wall penetration since it was still in excellent condition and changing the wall penetration is time consuming and complex. The pipes matched perfectly and the unit operates fine.
Lighting was straightforward – a note urging patience (up to 90 seconds to purge air from the gas pipe) was very helpful as it did take 55-60 seconds.
The outer exhaust pipe got quite warm during initial heating run but no problems was seen. Unit has been in and operating for a week now with no problems. In 15-20 years I'll know whether or not the unit's longevity matches the other reviews. If it does, I'll add the fifth star.

  • 50 Gallon ProMax Direct Vent Residential Water Heater (Propane)

    Q:

    Will this unit operate at higher elevations without any modifications? We are at 8000'
    Asked on 5/10/2016 by offgrid from Colorado

    1 answer

    • CUSTOMER CARE

      A:

      When installed at elevations above 7,700 feet (2,347 meters), input
      rating should be reduced at the rate of 4 percent for each 1,000 feet
      (305 meters) above sea level which requires replacement of the
      burner orifice in accordance with
      "Natural Gas and Propane
      Installation Code"
      CAN/CSA-B149.1. Contact your local gas
      supplier for further information.

    Q:

    I am planing on replacing my current FDV-50 with this GDV-50. The vent run will be under 30" and over 17". According to the guide I need to use the vent restrictor. What is that and does it come with the unit?

    • CUSTOMER CARE

      A:

      The restrictor setting is adjustable to accommodate all the different venting scenario's. The different positions are limits the amount of air flow into the unit for proper combustion to take place and allows for consultancy. And yes, it appears the restrictor plate is provided.

    How come I cannot get the temp regulated? When set to recommended setting I run out of hot water and when I set it up a notch its so hot at times it will burn your skin.

      It sounds like you may need to install a tempering valve in the system to prevent scalding.
