What is ignition time trial?
Trial for Ignition: Period during which the main valve and spark are energized in an attempt to ignite gas at the main burner. The control attempts to prove flame at the main burner within the trial-for-ignition time. Run: Main gas valve remains energized and the spark is turned off after successful ignition.
What is the function of an intermittent pilot?
The intermittent pilot light is an electric system, designed to combat some of the biggest flaws of the standing pilot. Rather than keep a flame burning all the time, the intermittent pilot only lights when needed. The system responds to the command for heat by using an electric spark to ignite the flame.
What is an interrupted pilot?
Interrupted pilot for a gas hearth product means a pilot that is automatically ignited when an appliance is called on to operate and is automatically extinguished after the main burner operation has been initiated.
What is the response time between the lockout of a standing pilot ignition system and an intermittent pilot ignition system?
Response time — For a thermocouple, about 180 sec; for intermittent ignition systems, 0.8 sec. Self-healing — (Special feature on some integrated fan controls.)
What is proven pilot?
UNIVERSAL PROVEN PILOT SPARK CONTROL. FOR ALL GASES. Microcomputer Based Gas Ignition & Primary Safety Control Designed for Interrupted Spark and Burner Supervision of All Gases Used in Gas Fired Appliance Applications.
What is a continuous pilot?
It’s a continuously burning flame at the bottom of the heater, responsible for starting the burners that actually generate heat for the home.
When lighting a standing pilot how long time should the pilot button be held down?
You light the pilot and hold the button down for 30 sec, and when the thermocouple sends the voltage to the gas valve, an electromagnet holds the main safety shutoff in the open position. In this position, pilot gas will always flow and main gas will flow on a call for heat.
What is a pilot turndown test?
If the flame rod is used to prove a pilot flame before the main. fuel valve(s) can be opened, perform a pilot turndown test. Follow the procedures in the Instructions for the appropriate. Flame Safeguard Control, and in the burner manufacturer’s.
How does a pilot igniter work?
A pilot light is a small flame that burns continuously inside of your furnace whether it is running or not. When your burners are ready to ignite, the main gas supply to your furnace is turned on and the pilot light is used to spark the flames in the burners.
What is continuous pilot?
CPI – Continuous Pilot Ignition, means your pilot light stays on constantly, even hen the fireplace main flame is not on. IPI – Intermittent Pilot Ignition, means your pilot is lit only on demand to ignite the main burner, right after you turn the fireplace on.
What is the difference between IPI and CPI?
IPI (Intermittent Pilot Ignition) is when the pilot light is only lit when the control board gets the call for heat, either from a thermostat or from someone flipping a switch. CPI (Continuous Pilot Ignition) is when the pilot is lit constantly.
How long should you hold pilot?
Lighting the Pilot Light on an Automatic Hot Water Heater But this time, do not remove any plates. All you have to do is hold the pilot knob down for 30 seconds and hold the ignition button at the same time. You do not need to use a lighter. Your pilot light will turn on!
How long should it take for a pilot to light?
To light a pilot light, first turn the gas control valve to off and wait 5 to 10 minutes until all the gas fumes are gone. Once you’ve made sure there’s no gas coming out, hold a lit barbecue lighter or long match next to the pilot light tube inside your furnace while turning the gas control knob to pilot.
What is the purpose of a pilot light?
As many know, a pilot light is a small flame that is kept alight constantly in order to serve as an ignition source for a gas burner. They are used on many gas appliances, such as water heaters, clothes dryers, central heating systems, fireplaces and stoves.
How to interpret the results of a pilot study?
How to Interpret the Results of a Pilot Study Conditions for a successful pilot study must be listed in advance. Depending on the fulfillment of these conditions, the researcher decides to proceed with the main study or to make modifications to the study design. Furthermore, results from the pilot study are described based on these conditions.
What is an external pilot study?
A pilot study is performed either as an external pilot study independent of the main study or as an internal pilot study included in the research design of the main study.
What is a pilot study in clinical trials?
A pilot study assesses if the randomization and blinding are appropriately executed [7,8,9]. For example, to appropriately use the sealed opaque envelopes method, which is often used in the clinical trials, the detailed procedures for preparation, storage, and delivery are assessed.
