Located on the back of the control board , at the bottom
right corner of the circuit board, is the connection for the thermostat. Our
units and replacement control boards come from the factory with a "shorting
wire" installed which makes a closed circuit across the thermostat
connections. this shorting wire must be installed for the unit to run
without a thermostat, and is removed only when installing a thermostat
This also makes thermostat problems easy to identify, the
basic problems you may see with thermostats are as follows;
1.
Wrong type thermostat for the stove, the system our control boards use
requires that the thermostat be of a certain type.
It must be a
"non-anticipated millivolt" or a 24 volt that is millivolt capable. Most
thermostats that are used for gas units are of this type.
2. Thermostat not leveled. wall thermostats of the
type used on our units are "mercury switch" type this type of switch must be
properly leveled when installed or adjusted to level the contact switch for
proper operation, if the thermostat is not leveled the unit may either run
for heat all the time, or run on its "low burn" all the time.
3. Broken wire/wrong size wire. most thermostat's
instructions will tell you what gauge (size) wire must be used for the
length of the run required. using the wrong type of wire can cause improper
function, usually causing the unit to run on low burn all the time. also, a
broken wire or bad connection either at the thermostat or at the stove will
make the unit run on low burn all the time |
