Sample Specifications Logic
CAF-12 Series
Construction
Heaters shall be 12” high, 53/4” deep, with the top and front constructed of extruded alu-
minum equivalent in strength to 14 gauge steel. The inlet grill shall be interchangeable,
front or bottom, and outlet grill located on the heater top. Cabinet back and bottom to be
fabricated from satin coat steel with multiple knock outs for convenient power connec-
tion. Endcaps to be field removable for continuous heater installation.
Color
Color shall be _____________________ (Standard White or Almond. Clear and Bronze
40 available).
Finish
Painted finish shall be hybrid polyester epoxy powder coat process. Clear and Bronze 40
are anodized aluminum finishes.
Heating Element
Heating element to be heavy duty, corrosion resistant, stainless steel sheath, enclosing a
nickel chromium element imbedded in compacted mineral insulation. Aluminum fins are
to be positively staked to the surface and provide superior heat transfer. Element is to be
located in a floating suspension system to eliminate expansion noise.
Controls
(Optional) Heaters to include built-in tamper proof thermostat mounted in the ________
(left or right) terminal box. Built-in low voltage control to be located in the right hand ter-
minal box. Built in disconnect switch is to be located in the right hand terminal box.
Power connection to be made at either the right or left end of the heater. A continuous
wireway to be standard to facilitate continuous installation of multiple heaters.
Thermal Protection
A linear high temperature thermal cutout shall be provided for the full length of the heat-
ing element.
