Checklist to Increase Unit Heater Performance and Safety
Winter is here, and it’s time to escape those cold temperatures by firing up the unit heater.
These small “heat in a box” units provide the necessary heat you desire for any commercial or residential space. Garages, warehouses, workshops and greenhouses can all benefit from these gas-fired unit heaters.
At Modine, your commercial HVAC leader, we have a variety of gas-fired unit heaters at our disposal. Our Hot Dawg™ series provides a variety of units that are suitable for personal workshops across the country. Our Hot Dawg™ is available in six model sizes, ranging from 30.000 to 125,000 BTUs. Each model runs on propane or natural gas, depending on your needs.
Each one of our gas-fired unit heaters is low profile, lightweight and easy to install. The versatility of these units makes them the perfect option to heat spaces not better served by a standard furnace. These unit heaters can be installed on a wall or hung from the ceiling.
While maintenance and installation for unit heaters are simple, it is important to let a licensed technician perform all necessary work on the unit. One wrong move could transform a simple problem into a larger issue. If a unit isn’t properly maintained, it could potentially damage the unit or cause safety concerns. Thus, it is important to regularly service the unit.
With that said, here is a basic technician checklist that will help guarantee the safety and longevity of the unit heaters:
- Check equipment, including fans, wiring, gas pipes, and venting systems for any damage that may have occurred over the summer.
- Ensure nothing is blocking the unit heater. This could decrease the efficiency of the unit and prevent it from fully heating a room.
- Check and adjust manifold gas pressure. Inspect all gas connections for proper fit.
- Make sure the motor shaft turns correctly and check the power connections to the motor.
- Check condensate lines on high-efficiency units.
- Examine thermostats for cleanliness, connectivity and correct temperature settings.
- Inspect burner tubes and make sure rodents haven’t nested in the burner over the summer.
- Be alert for indications of condensate leakage.
Regular maintenance is paramount to providing safety and efficiency for unit heaters. Proper maintenance is invaluable and inexpensive.
