Boiler Wiring Question

I need to properly wire my gas boiler, currently there is romex connected to it.
I know that is a no no.

Is it OK to suspend metal clad cable from a joist to the boiler or is rigid conduit required?

if it drops more than 18" it must be ridged or fastened to a fixed board.

Thanks for responding.

I assume when you say "ridged" you mean metal conduit?

You can use EMT,no need for rigid conduit,normally secured to a joist then down into a service switch mounted on the boiler,pipe can also be secured to boiler.

No. Rigid conduit (RMC) has the same dimensions as water pipe but with a different coating that is much smoother and has straight threads instead of tapered. Intermediate conduit (IMC) is still threaded but has considerably thinner walls. Electric Metallic Tubing (EMT) is also known as thinwall conduit and cannot be threaded. It has connectors that either utilize a setscrew or a compression ring to hold the connector to the conduit.

Installing a second Taco zone valve

P

pleahy74 on Feb 21, 2015

I have 2 taco zone vales and was currently just using them in the open position with one Tstat. I am now trying to add a second Tstat. I had a plumber walk me through the wiring procedure for this and it is not working. Zone 1 is firing properely but zone 2 is not. Now he is telling I need 2 Taco SR501 relay switches to run this. This is the rough drawing of how I have it wired: [ATTACH]46983[/ATTACH]

WeilMclean boiler goes into hard lockout

B

becket on Feb 24, 2015

Hi all, i keep getting "hard lockout" on my brand new R7284, every time "CAD CELL" 1045ohm. Burner tech has checked oil pump pressure and for any leakage, doesn't see anything wrong, that's when i bought another R7284. its a WeilMclean with a Becket burner. it can run for several hours but never gets through the night. is the default setup ok or do i need to make some changes? i tried 2 minutes on the "Burner Off Delay", was set at 0, still locking out. the description in the manual is not great, i'm wondering if the boiler tries to restart within a couple seconds after shutting off and there's still a small fire it locksout so i think if a delay the start and if there is a small flame it might go out during the time delay? it is set for "boiler". i read in other comments the CAD CELL is more around 500-600 ohm? my last 10 cycle and Baseline are both about 1050 ohm. The tech adjusted the air intake as the cad cell previously had 1600+ ohm and said that over 1600 would cause it to lockout. he's not sure what to do that's when i bought another R7284. thanks for any help.:wall::wall::wall: Becket [COLOR=#0000cd]Separated from...[/COLOR] [url]http://www.doityourself.com/forum/gas-oil-home-heating-furnaces/518477-honeywell-r7284u-oil-primary-hardlock-out-issues.html[/url]
