unit into a portable heating device where a fixed installation is not
required. This kit includes wheels, legs, handle, grill(s), baffle (if
reqd) and all of the necessary hardware to complete the modifica-
tion. See instruction bulletin PG435 for details.

The grill kit consists of one (1.5, 2, 4.5 and 6 kW) or 2 grill sec-
tions (13.5kW) and hardware to protect personnel from coming
into contact with hot radiant heating elements. See instruction bul-
letin PG437 for details.
Disconnect Kit
The disconnect kit consists of a complete assembly consisting
of a disconnect switch (3 Pole), power terminal block and all hard-
ware to complete the installation. This kit can be mounted to both
the fixed, overhead heater or the portable heater; see instruction
bulletin PG436 for details.

Hanger kits include 24 feet of chain and four S hooks to mount
the unit in a fixed overhead position using the universal mounting
brackets included on the heater. This kit allows installation dis-
tances from the ceiling of 2 feet to 6 feet. See installation diagram
