Masport Sofia - ECS Gas Heater Pizo comes on, gas burner starts/ lights normally, pizo cuts out normally, then the gas valve shuts off the gas and the flame goes out. Then the cycle starts again.

    Eventually, after ~10 starts, the unit heated up and stayed on last night.
    Tonight it will not stay on after ~20 starts.

    The manifold is clean and the gas comes out the manifold holes unifomally/ normally.

    It seems as if it is not registering that flame has ignited.

    I've looked for a thermocouple and have preheated what is called the "flame detector" in the manual.

    Preheating has not made any difference.

    I have checked for loose connections in all the wiring.

    The space heater flame has a normal (full flame after ignition, for 5 seconds; each time it ignites (20 times in a row).

    After 5 seconds of normal heating the machine shuts off the gas; waits 10-15 seconds, then the ignition sequence restarts.

    It would seem the sensor for the flame is not registering the fact, the full flame is on.

    The manifold and burner are clean.

    Any ideas on how to check the heat sensor and stop it turning off the gas??

    The air
    and gas mix then flows into the burner where the pilot flame or ignitor
    ignites it. On models with a spark ignition, there is usually a spark
    switch attached to the burner valve, a spark module and the spark
    ignitor. When you turn the valve, the switch tells the spark module to
    send electricity to the spark ignitor to create the spark to ignite the
    gas. Almost all older cooktops with unsealed burner units allow you to
    raise the entire top for cleaning and service.

Have a goodman gas pack and we lost power due to winter storm over night so now my unit is running but only cold air coming out

the pilot light runs from a very small gas jet and should not be affected by the power outage
however that is not to say that the jet may have frozen over and become blocked putting out the pilot light
AS the system needs power to drive the fan it is possible that without the fan and safety system working , the main gas supply solenoid would have shut down and that could have affected the pilot light
with the power reinstalled try lighting the pilot light
I would say that there would be a pizo starter on the front of the unit to light the pilot loght

I need to know how to light the oven? Does it have a pilot light like the stove top

most stoves do not have pilot lights but work from a pizo ignition system
when you turn on the gas knob ,the first action is to energize the pizo and that continually sparks to ignite the gas at the hob
the same is with the oven
ovens should be lit with the oven door open and once lit then the door can be closed

Loud backfiring noise upon start up.

the main jet is open before the pizo starts
for safety sake have a gas fitter look at it

Need help with Bosch hydropower 13h tankless hot water system

when you turn on the hot water tap there is a pressure switch in the line that sends a signal to a gas solenoid to pass the gas and at the same time to the pizo to start the flame
I would have that pressure switched checked as it may be sticking ( internal contamination) or have dirty corroded points
as gas is involved I would suggest a gas technician do the jib
when you turn off the tap, that pressure switch is shut off so the gas is turned off at the solenoid and the pizo is stopped.

How do you light the pilot on this heater

Hi and welcome to FixYa. I am Kelly. The instruction manual is here:

Steps to light the pilot are on page 10. This unit as a pizo-electric igniter that is suposed to light the pilot. When you open up the cover to light the pilotfollowing the manual steps on page 10 check the contacts on the igniter. Sometimes they get stuck together. You can lightly sand them with 120 grit or higher sand paper if the contacts stick.

Thanks for choosing FixYa,

Heater short cycles burner fires up won't stay on for long fan kicks on and chamber cools down and short cycle starts over again.......ther is a solid green led indicator lit up and I can't find so far...

i take it the burner is pizo fired(electrically ignited), if so, there is a flame sence wire down by the burner that senses the flame, if it don't, it shuts everything down for a short time then tries to restart. check senser at burner or circuit board.(a little more info would've been nice)

I replaced the thermocouple and now the ignitor does not work . the gas is on but no spark. and it did work before.

You need to check that you did not accidenatly move pizo when you install thermocouple. may need to shut unit off to snap test pizo ligher until you have adjusted ok.

Please rate. Thanks

One burner has no spark for ignition..

The problem is that the wire is shorting out where the black area is, that's what is causing the black mark.

It is called a pizo lighter, you will only need the section that is faulty, depending on the make/model (some require you to buy the whole pizo assembly).

You can get them from most plumbing suppliers and you should be able to get them from the retail outlet you would purchase the unit from. In each case they will have to order it in.

This is a tricky installation, and will just do the same thing if not completed properly, so if you are not totally sure of the task, please ring a plumber.
