†  Alternate grooved square, or round tiles may be specifi ed per Dimensions 4832/4834.

 These dimensions assume a

 3⁄8

" close nipple between burner and Sensitrol Oil Valve (see note).

 Pipe nipple not furnished by North American.

Basic information--all sizes:

1.  All results tested in cold, tight furnaces with burners mounted in 

side wall only.

2.  All stoichiometric fl ames are 

straight

 from 1 osi main air pressure and lower, semi-straight between 1 and 2 osi (fl ame length reaches 8" when 

straight).

3.  Burners applicable where extensive periods of oil fi ring are required, or excess gas in a cold, tight furnace is required.
4.  Pilots must be set to lowest possible rate.
5.  Stoichiometric operation on natural gas requires gas pressure be 50% of air pressure at the burner.
