Heated Area Coverage

The following shows the approximate footprint of the 3 different sized Heatstrip heaters. The quoted areas are for an open outdoor area with one wall and a ceiling.

Coverage Area Bracket Adjustable

Angle Mounting

The Heatstrip comes with the Standard Mounting Brackets in the box. These brackets can mount the heater to the ceiling or to a wall, giving it 4″ clearance.

The Standard Mounting Brackets (Part No: ZBRAK-103) are adjustable and can be rotated from the 0 degree position to be 22 or 45 degrees.

The Heatstrip can also be mounted on an angle along its length. See the Heatstrip Product Manual for more information

 

 


 

For Installers

 

Installing Electricians

Electrical work should always be installed by a qualified and competent electrician to the local building standards.

To check that the heater is running correctly. There are two components, the current and the voltage. To determine if there is correct power, measure and compare the readings to the heater rating.

 

Measuring The Current

Model Amps
THH1500AUL 15 Amp
THH2400AUL 20 Amp
THH2400AUM 20 Amp
THH3200AUL 20 Amp
THH3200AUM 20 Amp

It is recommended using a non-contact clamp meter to measure the current. The best place to measure is at the rear of the heater, or as close to the rear as the heater as possible. This will provide the most accurate reading as losses and interference are minimized.

See the table above for the specifications. Match the heater model to the current draw.

 

 

Measuring The Voltage

    
There are two options to measure the voltage.

Use a multimeter or an Electronic AC/DC Voltage Tester  -OR-  Use the probes and test the voltage at the gangbox of the heater.  This is the most accurate way to measure as line losses have already occurred.

 

Branch Circuits

Model Branch Size
THH1500AUL 15 Amp
THH2400AUL 20 Amp
THH2400AUM 20 Amp
THH3200AUL 20 Amp
THH3200AUM 20 Amp

The Heatstrip heater is classified as a continuous load. They are continuous as they can run for over 3 hours. When specifying the size of the branch circuit always used the maximum rated current. The element is an electrical resistive load.

For branch circuits, the size of the circuit is printed on the rear of the heater.

The size of the conductor used for the branch circuit is important as too small and it will overheat. The National Electrical Code (NEC) governs the size of the wire needed. The American Wire Gauge (AWG) is a common format to rate the size of the conductor and matches it to the current, length and ambient temperature.

There are electrical power losses on the circuit due to resistance from the length of the circuit. It is not uncommon to have a 50′ long electrical line, from the switchboard to the heater at the rear of the residence. When referring to resistance of the electrical line, the larger the conductor, the lower the resistance and the less power is lost

 

Electrical Protection Devices

It is recommended to always install circuit protection for the Heatstrip heaters. There are a variety of products available and your electrician can help with this. To assist we’ve covered a couple of them.

According to the National Electrical Code (NEC210 – Multiwire Branch Circuits), the Over Current Protection Device OCPD is rated to 125% of the rated current of the appliance. The OCPD is usually installed in the switchboard.

A Ground Fault Circuit Interrupter (GFCI) also known as a Residual Current Device (RCD) protects personnel from a short circuit by measuring the imbalance of the load. It is recommended to install a GFCI on the branch circuit.
This information is general in nature and is for education. Always refer to the NEC and local building standards to ensure a safe installation.
