(with or without thermostat and/or relays and/or switches and
accessories.)
Check the heater section dimensions and the additional wall
length required for telescoping accessories (Figure 1) before
starting wall-to-wall type installation. Be certain all heaters and
accessories needed are at hand and are of correct finish.

At correct height, draw a pencil line on the wall, level and/or par-
allel with the window sill. Minimum mounting heights above the
floor shall be as follows:
Minimum Mounting Height Above Floor
