Question about Star Enerco Heat HSU45 Garage Heater 45000 BTU

2 Answers

Gas heater thermostat installation.

I installed the whole unit and now I realized it has no thermostat. I plugged it in but all I hear is a click and a green light flashes on the mother board. How do we install a thermostat to a gas heater (HSU45 garage)? Where do I connect the wires. Do I need a thermostat with 2 or 4 wires? I noticed the unit has 4 screws on the mother board, do the wires go there and if yes in which order?
Sorry for the stupid question and thank you in advance for your help.

YOU CAN CONNECT A THERMOSTAT TO THE HEATER. FIRST DO YOU STILL HAVE THE MANUEL TO THE HEATER ? THE WIRING DIAGRAM SHOULD BE IN IT. USALLY ITS ONLY A TWO WIRE HOOK UP UNLESS IT HAS A JUST FAN CONNECTION ALSO,THAN ITS A THREE WIRE HOOK UP.IT SHOULD HAVE A BUSSBAR ON THE OUT SIDE OR THE INSIDE FOR THE 24VOLT THERMOSTAT HOOK UP.

First suspect is always to clean combustion parts.
I don't have that specific manual, but assume unit has digital gas control valve thermostat.
http://www.reliancewaterheaters.com/lit/om.html
As a general rule, the gas control thermostat activates the blower and turns on the gas, and controls flow of gas to pilot.

If the ECO is tripped, or there was FV event, or the gas valve thermostat is bad, or the combustion parts and tubes need maintenance and cleaning, then the pilot will not relight.

I turn on the power switch and the blower turns on and stays on. I can get the pilot light to stay on but the burners will not light even after I turn the RED gas valve to ON. There is no thermostat...


Hello Skyhalliday,

I understand that you are having a problem with you central heat/air. You do not have a thermostat installed and have the red and yellow crossed in order to make the unit run.

The wires you have crossed are not to the heat if they are to the common color code. Here is the color code for HVAC units:
Thermostat / Wire / what is controlled
W / White / Heat gas valve or heat elements
Rc(Rh) / Red / 24 volts transformer
G / Green / Fan
Y / Yellow / Air Conditioner Outside unit
C / Blue or Black / Common (energizes thermostats that do not have batteries)

You may not have the proper wires shorted in order to have the burners engage.

Thank you for choosing FixYa.com

I was told that i am being sent a replacement heater for my ae125. after looking at the unit i do not see how i am to remove the old heater. any help would be of great help.


It seems unprofessional that Bosch, or any tankless manufacturer, would suggest self-installment when each tankless manufacturer pointedly says their product should be install and maintained by person specifically trained by manufacturer. Especially when it is widely known that self-installed units can void the warranty.

That being said.
Cover on your unit should come off. Unit is attached to wall with screws/toggles at each corner.
Gas line (assuming gas heater) should have a union located on gas line near tankless unit.
Hot and cold pipes are located on bottom of unit.
Vent stack is attached to top.

Specific plumbing techniques are used for each item shown above.
If you are not fully qualified to work with gas appliances, or have no plumbing experience, I suggest taking advantage of fixya paid service where expert walks you through each step while you work on unit.
But you need the tools and vocabulary, and remember the expert cannot see what you are doing or know exactly what you are talking about.

Frankly, if you are not qualified, call a service technician.

JUST ,MOVED INTO NEW APARTMENT. PILOT IS LIT. WHEN I TURN THE THERMOSTAT ON NOTHING HAPPENS. iTS 36 DEGREES IN HERE AND I HAVE TWO SMALL CHILDREN PLEASE HELP!!


Solution 1: Contact your apartment manager and clear it up whether it had previous gas leakage issues. Have the person assist you in turning on the gas valve on the heater unit. (Most wall gas heater units have the red knob.)
Solution 2: If you don't hear the solenoid "clicking" on. (Solenoids control the opening/shutting off of the gas that is fed into the burner, and are actuated by the thermostat), then there is a problem with either your thermostat (i.e. paint got inside, or just plain broken). Have it replaced.

Gas is being delivered, pilot works but unit will not light


Make sure the switch on the thermostat is on heat.make the power to the heater is turned on.
if you can hear a click at the gas valve then it is stuck from sitting with out use.
