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.

Cozy gas wall heater won't ignite, pilot light is on


There are two types of igniters, spark-type or glow heater. The glow heaters wear out and crack or break and the spark-type spark gap gets fouled or dirty. Both could have electronics problems that drive the glow heater or spark systems. The Filtrete thermostat is not the issue. While rapping the unit makes the glow igniter come back together to glow again.

Make sure you are getting 24 volts back from thermostat and you are getting good connections. If you have 2 wires running to stat, connect them together at unit and see if unit starts. Check for wires unplugged, but I think that a flashing green light means you have 120 volts supply and the stat is not calling for heat

hi there

could have a faulty gas valve which may let in to much gas.extra load from the stove may be correcting this.
to much gas /too rich a mixture can affect internal temperatures causing thermostats to fail.
does the stove burn a nice strong bright blue flame?.

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.

above is a service manual, it will help toy troubleshoot and hopefully repair your unit. Be careful, if in doubt, call a certified gas fitter.
I would suspect, the thermostat, or some other sensor, as this is usually what's wrong.

How to install programmable thermostat


If it is a wall furnace with a built-in thermostat(sounds like the 1 to 10 dial is the thermostat) into the control then you would need to buy an updated gas contol valve that will hook up to an external thermostat and a programmable thermostat. The old gas contol valve would need to be removed and the new one installed. Then the thermostat wires would connect to the gas control valve millivolt system. A heating company can perform this service for you and I highly recommend you have it professionaly installed if you are not experienced on this process. You could leave a gas leak or other hazardous situation if not installed correctly.

Heater won't turn off. Wires were troubled


Shut off the gas to the heater. Bad gas valve. Gas should not be leaking from any part of the gas valve.
