Crimp-on connectors Used to secure twisted and untwisted joints. This type of connector
can be a slip-on metal cap for pig tail joints, or a metal sleeve for splicing two straight wires.
Contactor Similar to a relay, except that it contains large-load contacts designated to control
large amounts of current
The thermocouple only generates a voltage if the temperature difference between the hot and
cold junctions is at least ______ 400F
Voltage rating for thermostat 0-1.5VDC
Thermocouple closed test 10-15mV
Thermocouple drop test 2-4mV (90 second duration)
Thermopile closed test Over 140mV
Thermopile closed test (with load) 140-275mV
Thermistor programable thermostat
Heat anticipator A mechanical thermostat that controls system overshoot
Pressure between 1st and 2nd regulator should be? Maximum 10psig
,Loading element Usually a spring
Measuring element Usually a diaphragm
Restriction element An orfice and valve seat
Atmospheric vent A vent on the atmospheric side of the diaphragm
Over pressure shut off valve To pipe your system outside you would need
Balancing Diaphragms Separates the lower main diaphragm area and the upper valve
section. It creates a balancing and stabilization in the pressure.
Lockout Pressure When you have an immense amount of downstream pressure moving up
once youtube turn off the regulator
Zero Governors Designed to deliver an outlet pressure equivalent to the atmospheric
pressure. They are normally double-diaphragm units equipped with an 0-ring seal diaphragm
(balancing diaphragm). This isolates the inlet gas pressure from the lower chamber of the main
control diaphragm.
Droop and offset The downstream pressure drop below set-point
Set-point The desired outlet pressure
Lockup The pressure above setpoint that is used to shut the regulator off tight
, Criteria to evaluate the various overpressure protection Continuity
Where the excess flow is directed
System failure Warning
Overpressure Protection Pressure relief using relief valves
Monitors
Automatic shut-off
To increase the run cycle of a furnace you should? Increase heat anticipator setting
When installing a jumper to R&W, the R&W thermostat wire must be removed, if not then
Heat anticipator will burn out
Incoming power supply from streets into a house 240/1/60
As the gage number of conductor decreases the resistance Decreases
As the gage number of the conductor decreases the voltage drop Decreases
As the temperature of NTC thermistor increases, its resistance Decreases
As gage number of conductor decreases the current carrying capacity Increases
Use ridged pipe or flexible metal Used for dryer vents
The seam for gas dryer vents should be upwards and slopped towards Outside
