INSTALLATION<br />
This portion of the workbook will review some often overlooked installation considerations, taking<br />
note of necessary installation requirements for the <strong>BTC</strong> <strong>120</strong>-<strong>500</strong> 970 through 971 series heaters,<br />
and the <strong>BTC</strong> series 962-967 models which have been converted to Honeywell ignition systems.<br />
The installation manual covers most of these items in detail.<br />
Note: For <strong>BTC</strong> models prior to 962 series, see troubleshooting manual TC-015.<br />
FROM COMBUSTIBLES OR NON-COMBUSTIBLES AS WELL AS SERVICE<br />
<strong>BTC</strong> heaters are approved for installation on combustible flooring. Most can be installed in an<br />
alcove with minimum clearances to combustibles or non-combustibles of 6 inches from the<br />
sides and rear, 6 inches from any draft hood surface or vent piping, and 12 inches from the top<br />
cover. A 24 inch clearance for all serviceable parts is recommended. Clearances may vary<br />
between <strong>BTC</strong> models – See instruction manual or the label on the heater, for clearances<br />
applicable to your specific model.<br />
