This is why it's always a good idea to use the code box for models, subckts etc. Click advanced on your reply/post and you'll see the "#" button.

Like this:
Code:
* TML300b LTSpice model corrected by 1/2 heater volt
* Modified Koren model (8 parameters): mean fit error 0,8mA
* Traced by erik 25/12/2013 using Curve Captor v0.9.1
* pentaTJ300B LTSpice model
* pentaEML300b LTSpice model
.subckt pentaEML300b  P G K
    Bp  P K   I=(0.1471360425m)*uramp(V(P,K)*ln(1.0+(-0.0836812242)+exp((14.77238937)+(14.77238937)*((4.    010010839)+(0.03955144628m)*V(G,K))*V(G,K)/sqrt((2.786333203e-006)**2+(V(P,K)-(2.303526987))**2)))/(14.77238937))**(1.48386058)
  Cgk G K 8.5p ; 0.2p added
  Cpk P K 4.6p ; 0.5p added
  Cgp G P 15.5p ; 0.5p added
  Rpk P K 1G ; to avoid floating nodes
  d3  G K dx1
.model dx1 d(is=1n rs=2k cjo=1pf N=1.5 tt=1n)
.ends pentaEML300b

I've been fooling around with Spice. I put the generic triode symbol on a schematic. Then right clicked to open Component Attribute Editor. In the 'value' box I put 2A3. On the schematic the generic triode symbol is now labeled 2A3. Does that mean the model is attached to the symbol or is it just named 2A3?

Use the SpiceModel box instad of the Value box. You should also read this post on how to add models to your simulations:
Installing and using LTspice IV. From beginner to advanced.
