Question: Customer is asking me to install 2 panels for Infratech heaters so the bottom of the panels would be above 6‘6“Is this a cold violation? Thank you

You're likely asking if installing Infratech heaters with the bottom of the panels at 6'6" (6 feet 6 inches) violates any electrical codes. Here's a breakdown of considerations

1. NEC (National Electrical Code) - USA:
Clearances from Combustible Materials

This is the MOST critical factor. Infratech heaters generate significant radiant heat. The NEC (and the heater manufacturer's instructions) will dictate required clearances from combustible materials (wood, fabric awnings, etc.).
This is not just about height, but also about side and front clearances. Exceeding 6'6" for mounting height doesn't automatically solve clearance issues.

Working Space

While not directly related to the heater itself, ensure adequate working space is available in front of the electrical panel feeding the heaters (if it's in the same area).

Specific Heater Requirements

Always, always, always consult the Infratech heater's installation manual. It will specify the minimum and maximum mounting heights, required clearances, and other critical instructions to comply with listing requirements.

2. CEC (Canadian Electrical Code) - Canada

The CEC will have similar requirements to the NEC regarding clearances from combustible materials and working space. Again, consult the Infratech installation manual for specific requirements.

3. Local Codes and Permits

Your local municipality (city, county, etc.) may have additional or more stringent requirements than the NEC/CEC. Contact your local building department or electrical inspector before starting the installation. A permit might be required, which will trigger an inspection.

In summary, 6'6" might be adequate from a general height perspective, but it's not a guarantee of code compliance. The critical points are



Infratech Installation Manual

This is your primary guide. Follow it precisely.

Clearances from Combustible Materials

Verify that the 6'6" height provides adequate clearance based on the heater model and the surrounding environment.


Local Codes and Inspections

Contact your local building department to confirm requirements and obtain any necessary permits.*

Accessibility

If you are in a commercial setting you must be compliant with ADA which may stipulate accessibility issues.

Recommendation


Obtain the Infratech heater model numbers.
2. Download the installation manuals for those models from Infratech's website.3. Carefully review the installation instructions, paying close attention to mounting heights and clearance requirements.4. Contact your local building department or electrical inspector with the model numbers and a description of the proposed installation. Ask if there are any specific local requirements.

By following these steps, you can ensure a safe and code-compliant installation. Flag for review
