A note probably gets your current plancheck item satisfied but it doesn't
satisfy some other conditions such as 
-safe platform height (gaseous ignitor)
-auto barrier
-vents top & bottom of door to a closet water htr

Here's a link to a detail I use (instead of specification words)

| :I don't do a lot of residential work, but I've got a plan check correction

| :CPC 510.5".

| :What is normally done to comply? A note? A detail?
| :
| :Aren't there kits at Home Depot for this?

| :I don't want to "over-engineer" (I HATE that term!) this thing, but I want
