Bosch Tankless Installation

Hi my name is Chris Rizzo technical  trainer for Bosch thermal technology and  today we’ll be covering the installation  of a c12 10 es the C in front of any  model number for any of our tankless  water heaters designates that water  heater as a condensing model once you  get your water heater and you’re looking  at the side of it always make sure you  got the right water heater that you  designed for the next thing you want to  make sure of is that.

It’s the right gas  type if you ordered a natural gas it  should be labeled on the label itself as  you’ll see here this is a natural gas  unit and the ng symbol is located here  on the label the number in the model  number is derived from a maximum flow  rate at a 35 degree temperature rise the  e in any model number is a reference to  the electronic ignition and the S is for  sealed combustion if any model number  has a c before the maximum flow-rate  number then that model is a condensing  model if any unit has a c at the end of  the model number then that unit is a  designated commercial unit and has a  maximum temperature of 180 degrees the  next thing of course is that you’re  going to want to get the the unit out of  the box itself so the first thing that  you’re going to want to do is you’re  going to want to open the top of it  everything that you need as far as vent  adapters if this is an indoor unit will  be located in the top of the box  so once you open it what you’ll see is  the intake vent adapter exhaust vent  adapter the gaskets will be located  inside this bag as well as the screws so  you’ll have your two gaskets this is  your intake gasket this is your exhaust  gasket so you’ll have those inside the  box and always make sure.

That those are  there as well your mounting screws for  the bracket that will be on the wall  behind me the next thing that you’ll  want to take out here is the other  mounting screws exhaust and adapter one  of the more important things that you’ll  want to take out of here is the  instruction guide  this is your manual that will come with  the unit once again it’ll have the model  number at the top the c12 10 es also  comes in a commercial model which is the  ESC residential models go up to 140  degrees commercial models go up to 180  this is the largest tankless condensing  water heater on the market with 225  thousand BTUs the best way to register  the unit is to go to the Bosch way to  grow website and register your install  there I would highly encourage this as  the website is full of sales offerings  great prizes and leads for your company  it’s a great way to grow your business  and to partner with one of the world’s  biggest appliance manufacturing  companies the alternative is to fill out  the registration form located in the box  that the unit came in we’ve got that  inside another thing that will be  located inside the top of the box where  the styrofoam is the hanging bracket.

This is what you’ll mount on the wall  you’re going to make sure that it’s  level and I’ll show you how to do that  you’ll mount this on the wall and the  unit will actually hang from this  particular bracket the holes on this  bracket from this side to this side are  16 inches on center so you’re going to  want to have a stud finder whenever  you’re hanging this particular bracket  if not this unit weighs 80 pounds you’re  going to want to get something that will  anchor it to the wall that’ll be able to  hold that particular weight if you’re  dealing with a concrete or a brick wall  you’ll want to use red heads or  something like that  but if it is just a residential install  you’ll want to find those studs and put  this bracket on it so let me get this  out of the way and there is a little  method to the madness as far as taking  the unit out of the box –set online  install stuff off the sign here also the mounting screws for the vent adapter  bracket or for the vent adapters  themselves are located in the top of the  box as well.

They’re kind of small they  can get lost so you’ll definitely want  to put them somewhere safe where you  won’t kick them or drop them in the dirt  or anything like that but they  definitely come with it  now the easiest way to do this is to cut  the bottom of the box now fold the top  up get in that way the bottom you don’t  have to worry about scratching it  there is another styrofoam that’s at the  bottom of the box and you can go as deep  as you want to so long as you don’t  really go any higher than about two  inches take this guy out him off to the  side and that’s the easiest way to tank  out a Bosch tankless water heater now  the next thing that we’re going to do in  this process is take our hanging bracket  will also need a level and you’re going  to want to find the studs in this  particular case we’re mounting it on a  brick wall so no studs are necessary but  I still want to make sure that this  thing is level so put him on the wall  you’ll want to make the height of it  about 66 inches or so this is a perfect  height for any service that you may have  to come back and do getting access to  the actual isolation ball valve kit this  will just make your life a whole heck of  a lot easier so just take your level  make sure that it is exactly level  itself and then.

We’ll screw this to the  wall once you have the unit out of the  box and it’s out in the open you’ll want  to install the flu adapters now the  exhaust is always going to be in the  center it’s very important that you keep  the combustion gas analyzer port facing  the front of the unit itself you don’t  need a combustion gas analyzer to  actually install a unit but you will  need one maybe in the future if you’re  going to do any service on it there  should be no issue with installing one  from zero to 2,000 feet  eat anybody who’s in high-elevation  definitely understands that they need  one in case they’re running any of the  vent links to their max so the first one  that you’re going to want to install  like I said is this exhaust gas adapter  now the flue actually needs this gasket  it’s a little hard it’s a little twisted  but it does have a sticker or a sticky  substance on one side of it this yellow  is what covers it up now you’re going to  have to separate him like that okay peel  it off make sure they don’t stick to  each other get that guy away open him up  and the easiest way to turn this over  put it down and line up the holes can be  a little bit difficult but once you’re  there move it line up one hold it’ll  stretch some it can be sticky  that that got it and your gasket should  look similar to this now.
