Claim 10

The heater according to claim 8, which includes: (a) a reflective metal panel positioned over said insulation layer.

Claim 11

The heater according to claim 1 wherein said heat lamp comprises: (a) a pair of quartz tube heat lamps, said heat lamps being adapted for emitting radiation in the infrared range.

Claim 12

The heater according to claim 1, which includes: (a) an electrical system including a variable power source.

Claim 13

A heater, which comprises: (a) a mounting frame including: (1) first and second clevis legs positioned in transversely opposed relation; (2) a transverse guide bar extending between said clevis legs; (3) a stop collar slidably receiving said guide bar and positioned in proximity to said first clevis leg and having a set screw for securing said stop collar to said guide bar; (4) a slide tube pivotably and slidably receiving said guide bar; and (5) a pair of slide tube legs mounted on said slide tube and extending therefrom in parallel, spaced relation; (b) a heat deflector assembly including: (1) a main heat deflector panel mounted on said slide tube legs and having upper and lower ends, upstream and downstream faces and a central opening; (2) an exhaust fan mounted on said main heat deflector panel downstream face in communication with said central opening; (3) an auxiliary heat deflector panel connected to said main heat deflector panel and extending in a downstream direction from said main heat deflector panel downstream face in proximity to the main heat deflector panel upper end, said auxiliary heat deflector panel forming a dihedral angle with said main heat deflector panel; and (c) a heat lamp assembly including; (1) a heat lamp enclosure with upstream, downstream and top panels comprising reflective material and opposite ends; (2) a layer of insulation placed over said enclosure top panel; (3) a reflector panel placed over said insulation layer and comprising reflective material; (4) a transverse quartz tube heat lamp positioned in said enclosure and extending between said opposite ends thereof; and (5) said enclosure being mounted on said main heat deflector panel downstream face in proximity to the lower end thereof.

Claim 14

A heater, which comprises: (a) a mounting frame including: (1) first and second clevis legs positioned in transversely opposed relation; (2) a transverse guide bar extending between said clevis legs; (3) a stop collar slidably receiving said guide bar and positioned in proximity to said first clevis leg and having a set screw for securing said stop collar to said guide bar; (4) a slide tube pivotably and slidably receiving said guide bar; and (5) a pair of slide tube legs mounted on said slide tube and extending therefrom in parallel, spaced relation; (b) a heat deflector assembly including: (1) a main heat deflector panel mounted on said slide tube legs and having upper and lower ends, upstream and downstream faces and a central opening; (2) an exhaust fan mounted on said main heat deflector panel downstream face in communication with said central opening; (3) an auxiliary heat deflector panel connected to said main heat deflector panel and extending in a downstream direction from said main heat deflector panel downstream face in proximity to the main heat deflector panel upper end, said auxiliary heat deflector panel forming a dihedral angle with said main heat deflector panel; and (c) a heat lamp assembly including; (1) a heat lamp enclosure with upstream, downstream and top panels comprising reflective material and opposite ends; (2) a layer of insulation placed over said enclosure top panel; (3) a reflector panel placed over said insulation layer and comprising reflective material; (4) a transverse quartz tube heat lamp positioned in said enclosure and extending between said opposite ends thereof; and (5) said enclosure being mounted on said main heat deflector panel downstream face in proximity to the lower end thereof.
