Can this be vented vertically?
Asked by: DM
Not sure who is "Community Answer" but the answer provided here is wrong. Instruction manual describes a vertical vent set up as the "preferred method". It also provides for a description of the material needed to set up a vertical vent for this unit, as well as an illustration showing how a vertical vent is to be set up (see attached image).

Is it legal to install in "manufactured home" that has been permanently 'moored' for 20 years on 5 acre NM lot?

some one told me it couldn't be installed on a 'mobile home'. my home is anything but 'mobile'.
Asked by: Nevermind
I can't imagine why your location and type of house would have any bearing on where this can be installed. water is water. your closet or other surroundings are the same, whether in a manufactured home, a stick built one or a cave. Yes put it in if you like it.I have on high in a closet in the middle of my home. it is not this brand. I got mine at a super discount form that other home improvement store. what I didn't know was that the stainless still double walled vent pipe was over $50 a linear foot! i had to go through a 12' high attic and 3' above that for a total of 18 feet of pipe. Way too much money so go with one that requires a PVC vent. I hope you have better sense than to ask a silly question like this in the future.

4.3 GPM Natural Gas Digital Panel Tankless Water Heater is rated 3.3 out of 5 by 27.

This was a replacement for an older model of Marey tankless. there is one draw back to this water heater and that is something you need to understand. It requires 0.8 gallons of water to move though it in order to turn on and REMAIN on. This can make showering a pain in CA especially if you have low flow shower heads 1.5 gal/m . Yes it will tun on and heat your water when you have only the hot water on and fully running but if you like warm showers you have to remember that when you adjust the temperature you also adjust the amount of water flowing though the heater. If the water flow slows to much it will shut off in the middle of your shower. Even with the gas on low, with summer setting, and the flow rate turned all the way up I was getting 135* water. The digital thermostat display helps to dial in your water heater for optimum temperature and usage. the plus side of it turning off in the middle of your shower is that it encourages you to take quicker showers saving water. Be sure of the gal/m usage of your dishwasher, shower, and clothes washing machine. These can all be affected.

When It would stop just after starting I tried calling and emailing for help. No one answered the phone no recording. No return email. Customer support doesn't exist. Now I need to buy a reputable brand.

I have had it just over a year and it has never worked correctly. The water temperature fluctuates wildly, no matter how many times I’ve tried adjusting the settings. The water will often go cold mid-shower and the faucet must be turned off completely and then turned on again to reset. The water will also heat up unexpectedly, enough to cause burns if not adjusted quickly. At right about the one year mark, the water heater also began leaking . The company, Marey, is extremely difficult to reach by phone, and sometimes outright impossible (the line rings and rings, then disconnects). Email seems the only reliable way to contact them, and even then it takes several days to get a response. I tried contacting Home Depot to help as well, but because I did not purchase their special extended warranty, all they did is direct me back to Marey. The manufacturer’s warranty isn’t useful either – parts and labor are covered for the first year, but you have to completely uninstall the unit and pay to ship it to Florida for service! In my case, the leak began just after the one year mark, so only parts were covered. After several emails back and forth, including detailed photographs of the unit, Marey sent me a new heat exchange as they believe it is the source of the leak. They insisted the heat exchange is easy to install and suggested I look up the company’s YouTube videos to figure it out. This seemed far too complicated for me, so I hired a professional. Even the repairman suggested just replacing the entire unit because the new part is so awkward and difficult to install! Neither he nor I could see any way to install the new heat exchange without severely bending the aluminum frame, as the screws do not line up with any openings in which you could maneuver a screwdriver. To top it all off, I have seen no difference in my utility bills between this tankless water heater and the old fashioned one I replaced. It was also incredibly difficult to install and required a lot of specialized parts that had to be ordered. After 14 months of use, I am ready to just trash the whole unit and buy a new one of a different brand. I absolutely would not recommend this water heater – or anything by Marey. I am also disappointed that Home Depot is not standing by the products it sells or offering any further assistance in resolving this issue.

We bought the 4.3 GPM and have had problems with it. It dispenses the hot water, but when you turn on the cold, the hot water stops. We have called Marey numerous times, and every time we are put on hold for a very long time, and eventually we are disconnected. Very bad customer support. Believe me, DO NOT BUY MAREY products.

Rated 1 out of 5 by from Worst purchase ever It's a nice compact device but it doesn't work properly, I only get hot water in the shower, it gets pretty hot and the moment I open the cold water to level out the temperature or to try and make the water a little warm the heater automatically turns off and only cold water comes out. I'm very unhappy with this water heater

Water is a lot hotter than i ever had from the previous storage tank source. Had to change my shower head to one that allowed more drop in water pressure so as to trigger water heater 'on' more consistently.
