My ideal logic combi 30+ is saying ignition lockout and my radiatiors arent heating up as well as my water not turning hot. How can i fix this please?


Lockout is a safety feature. Usually a latching condition and needs to be investigated rather than blindly reset. (The Combi has a bit more intelligence.) With the ignition locked out, you can't hi-fire the boiler, so no hot water of either type. The 'L' should also show a code number - check your user manual (google) for more guidance.

I've had a lockout on a non-combi: it was caused by lack of circulation of central heating water through the boiler.... The system boiled and the trip tripped. The pump WAS running, but wear in a valve actuator resulted in the valve feedback saying valve open while it was physically shut.

Rheem Intelli-vent intermittently goes in lockout mode


Rheem does not post service manuals.
However AO Smith has posted relevant service manual:
http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html#intellivent

Have you cleaned the air intake located under combustion chamber, and inspected for broken glass vial?
Rheem FVIR system uses glass vial that breaks if combustion air is slowed, and resulting combustion causes slow-moving venting of hot gasses, causing overheating that breaks glass vial.
http://waterheatertimer.org/How-to-repair-Rheem-FVIR.html

Check gas pressure.

Is there a reset button for a 6G50NVH-FV-02 hot water heater


Depends on gas control valve, and if cause is overheating high-limit event or FVIR flammable vapor event.
Turn off water heater when using flammable vapors, clean burner parts to prevent overheating.

1) GSW Residential power vent gas water heater with FVIR system:
Some models have intelli-vent gas contol
Others have robershaw gas control with auto-reset

2) Parts manual shows #15 'auto-reset' high limit switch on the blower
http://www.gswpartsonline.com/model/27484
http://www.gswpartsonline.com/schematic/137/view

3) Possible manual:
http://www.gsw-wh.com/pdfs/GPD135NInstall.pdf
Shows resettable lockout page 15
Water temperature must be 120 degree F or lower for reset. Unplug power cord, and then plug back in and wait 15 minutes or 60 minutes depending on gas control valve.
Some intelli-vent controls must be replaced when 195 degree high limit event locks out the water heater.
If high-limit lockout repeats, then gas control must be replaced.
Also clean burner parts, air intake, and make sure flame is clear blue. and not yellow-or-orange.

4) Intelli-vent service manual might apply to your water heater:
http://waterheatertimer.org/pdf/Intellivent-service-manual.pdf

If FVIR flammable vapor event locked out heater, then unplug heater and plug back in.
Immediately press two temperature buttons. Wait for green light to blink. Release buttons.

Hot water heater pilot is off. It's not gas,


You have tank-type gas water heater:
Open following link to watch thermocouple replacement.
Make sure new thermocouple sits into pilot flame. Instructions for relighting water heater are usually printed on side of tank.
http://www.youtube.com/watch?v=v0aBPsNg6vo

Gas water heaters need working thermocouple, adequate incoming fresh combustion air with no trace amounts of chemical, open vent to outside that drafts poison combustion product upward, clean burner tubes and combustion parts, correct gas pressure with no air in line, working gas control valve thermostat, no lockout condition such as tripped ECO caused by runaway heating and dirty combustion parts, and no lockout condition such as exposure to flammable vapors.
Open following links for troubleshoot resources:

The water heater is locked out. The following process should reset it.
1. Reapply power to the water heater and wait for 3 seconds for the system self-diagnostic check.
2. Within the first 30 seconds, the temperature dial must be rotated back and forth crossing the 120
degree mark at least six (6) times. This will reset the control and display a normal flash code
(slow blinking).
