We do not have a manual for these new heaters that have been installed in our school. We want to know how to adjust the temperature. At the moment it sits on 18 or 26, are there any instructions available that we can get to help us use these heaters.

use b to adjust temp lower setting.




Suburban SW6P Installation And Operation Manual For Your Safety Read...

Hi Sharon, I'm glad to help. Your 2000 year doesn't have a motor for the temp door. It operated by a cable running from the control head to the temp door and you work it manually. If you can't control the temperature from hot to cold, sometimes the cable come off or breaks. Here how you can see the cable to see if its working. Remove the radio and right behind it you will see the cable attached to the door, while watching it move the temp lever from hot to cold and watch it. If it is moving then its most likely out of ajustment. If it is not moving, then you'll need a new cable. Just in case it is moving, I'm attaching the instruction on how to adjust it below. Hope this helps and have an awesome day Sharon!

TEMPERATURE CONTROL CABLE

Any time the heater-A/C control or the temperature control cable are removed and/or replaced, the following procedure must be performed.

1. The temperature control cable housing and core must be installed at both the heater-A/C control and the heater-A/C housing ends, and the heater-A/C control must be installed in the instrument panel. See Heater-A/C Control and Temperature Control Cable in the Removal and Installation section of this group for the procedures.
2. Rotate the temperature control knob on the heater-A/C control so that the knob pointer is in the 12 o'clock position.
3. Pull the temperature control knob straight out from the heater-A/C control base until the perimeter of the knob (not the knob pointer) protrudes about 6 millimeters (0.25 inch) from the face of the control base.
4. Rotate the temperature control knob to the 1 o'clock position. Push in on the knob slightly and continue rotating the knob to its full clockwise stop. The knob pointer should be aimed at a position about 8 millimeters (0.315 inch) beyond the end of the graduated red strobe temperature control graphic on the face of the heater-A/C control base. If the knob is not pointed to the correct position, go back to Step 2 and repeat the adjustment procedure.
5. Rotate the temperature control knob counterclockwise until the knob pointer is in the 12 o'clock position again.
6. Push the temperature control knob straight in towards the heater-A/C control base until the perimeter of the knob (not the knob pointer) is flush with the face of the heater-A/C control base.
7. Rotate the knob to its full clockwise stop again. The knob pointer should be aimed at the end of the graduated red strobe temperature control graphic on the face of the heater-A/C control base. If OK, go to Step 8. If not OK, go back to Step 2.
8. Rotate the knob to its full counterclockwise stop and release the knob. If the knob springs back from the counterclockwise stop, the self-adjuster clip that secures the temperature control cable to the blend-air door lever is improperly installed. See Temperature Control Cable in the Removal and Installation section of this group for the procedures. If the knob does not spring back, the temperature control cable adjustment is complete.

Replace gas control valve.
The gas valve is the thermostat.

Vacation setting should be 50 degrees, or so, depending on exact gas control valve.
If gas water heater is not responding to temperature setting, then thermostat is suspect.

Open following link to help identify tank-type gas valve.
http://waterheatertimer.org/How-to-adjust-water-heater-temperature.html
Each gas valve should have identifying number on side.

1) The best place to find this information in your manual.
Typical Rheem manual in my files shows temperature is adjusted by pressing UP and DOWN temperature buttons on remote.

2) Manual says: Temperatures of up to 140°F
(60°C) for Light duty models and up to 180°F
(82°C) for Heavy Duty models can be
achieved with the MAIN (UMC-117) remote
control and a dip switch adjustment. Only
qualified service personnel should perform
this adjustment. Only factory authorized
remote control(s) should be used.

3) Typical manual shows information on page 22-23. Search pdf for 'temp'
http://waterheatertimer.org/pdf/Rheem-RTG74IndoorOutdoor_owners.pdf

4) This information squares with what I heard before that trained service technician is needed to adjust water temperature.
I think Rheem does this since tankless will not achieve that rise in temperature if incoming water is cold.
BTUs put out by tankless burner has limit.
If incoming water is colder than certain temperature, then tankless cannot raise temperature quick enough as water passes through burner.

5) You might also need a tempering tank, to modify cold water in winter:
http://waterheatertimer.org/Tempering-tank.html

6) Suggest you also read the yearly maintenance required for tankless.
For example tankless are prone to lime build up and need to be de-limed each year with vinegar.
Lime build up will certainly affect water temperature.

Hi,

Here is a tip that I wrote to help people understand how to adjust the temperature on their electric hot water heater.

Electric Hot Water Heater Temperature Adjustment
heatman101

Before you install the temperature control knob, adjust the valve body (47111) with a wrench to set the temperature to "100 degree or close to it". Now, place the limit ring to tdc (top dead center) and control knob with the red 100-degree align to it. Your problem may have been the valve's temperature setting is out range when you installing the temperature control knob.

Check in your manual for the thermostat. By pushing a combination of buttons you can get into the advanced installer menu. From there you can make an adjustment to correct the temperature.
