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.

Before Installing
1. Open carton and remove heater at the place of installation.

Mounting clamps are in parts bag in carton.

2. Check nameplate volt and watt rating against your power sup-

ply voltage and heating requirements of your installation. This
nameplate is located on one end of the heater.

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.

3. Minimum safe height above floor level for combustible mater-

ial is 6 feet (72”). However, if ceiling height permits, more
practical height is 8 feet or more to avoid high radiation inten-
sities at head level when one stands directly below heater.
