How / where should this be capped off when going back to electric (there is a shutoff )
(What icon do I use to post a pic ?)

There is a small shut off valve where the flex line ends ( it's actually in the next cabinet)
1. Does a small pipe/ cap have to be added when the yellow flex line is removed ?
2.Can the flex line stay ?
3. Is a "dead leg ok on the system like this ?

It's hard to tell but if that's two gas connecters connected together it's probably against code that they are passing through the cabinet.

QuoteClause 6.21.2
A gas connector shall
a) be protected from damage;
b) not pass through a wall, floor, ceiling, or partition;
c) be connected to rigid piping or tubing located in the same area as the appliance; and
d) comply with Clauses 4.5.2 and 4.9.1.

I would remove everything and install a nipple and cap into the shut off valve.

QuoteClause 6.12.1
During the period when an appliance is not connected to an outlet of a piping system, the outlet shall be made tight by means of
a) a plugged valve; or
b) either a cap or plug made of material compatible with the material of the piping or tubing system.

Where are you referring to 2 gas connectors ? Is a cabinet still considered a wall ??

1. If I remove the flex hose can I cap the silver flare connection is that allowed ? The silver connection is connected to black pipe
2. If I cap after the shutoff is there a rule of how long the pipe should or should be

I think a flex connector should only be used when there is an appliance to connect it to.

Any length nipple would be approved.

Does it matter pipe dope or thread tape ??

Either as long as they have CAN/ULC-S642 certification.

QuoteClause 6.9.6
When a jointing sealant is used, it shall be certified to CAN/ULC-S642 and shall be applied to the male threads of a metal pipe. Tape shall be stretched and applied in a clockwise direction, with a 50% overlap leaving the first two starter threads bare.
