Chromalox PG417-3 Installation, Operation And Renewal Parts Identification

Chromalox Type SKR radiant heaters are designed for indoor
installation only, and are to be ceiling mounted with such spacing
between heaters to project heat radiation downwards to maintain
comfort level within the radiation field.
MOUNTING (See Figure 1)
1. Layout heater locations to the desired heat affected work area.
2. Minimum spacing to walls and ceiling are —
A. One foot (12") from top of heater to ceiling.
B. Two feet (24") from side or end of heater to adjacent walls.

ial is 6 feet (72"). However, if ceiling height permits, more
practical height is 8 feet or more to avoid high radiation inten-
