† 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.
