Modine Commercial Workspace Heater - 400K BTU/Intermittent Pilot Ignition/NG/Single Stage w/Aluminized Steel Heat Exchanger & Burner
Features
- Made in the USA
- 83% thermal efficiency, maximizing seasonal efficiency through the use of a collector box and the power exhauster
- A power exhaust can rotate 180° allowing the unit to be vented vertically or horizontally
- A 100% shut-off if the unit does not light, to ensure that unburned gases do not build up in the unit
- An intermittent pilot-ignition system with continuous retry to keep the unit from locking and needing to be reset if the unit does not light on the first try
- All PDP/BDP units can be field-converted from natural gas to propane if desired
- A safety pressure-switch monitors the vent pipe to assure flue gases leave the building and do not back up in the space
- Designed to utilize the smallest-diameter vent pipe possible
- “Wing” screws so that the bottom pan can be dropped without a screwdriver or nut driver
- A level hanging mechanism for easy field adjustments after adding accessories that may change the unit’s center of gravity
- Draws combustion air from inside the workspace
- 6" vent connection
- Natural Gas
- 400,000 BTU
- Intermittent Pilot Ignition
- Single stage - on/off operation
- Aluminized steel heat exchanger & burner

Maintenance Tips
-
Check Gas Lines & Connections – Regularly inspect the natural gas lines for any leaks, damage, or loose connections to ensure safe operation.
-
Clean the Heat Exchanger & Burners – Periodically clean the aluminized steel heat exchanger and burners to avoid dirt accumulation that can impair performance.
-
Inspect Air Intake & Exhaust Vents – Ensure air intake and exhaust vents are clear from obstructions to guarantee proper airflow and avoid overheating.
-
Test Intermittent Pilot Ignition – Check that the intermittent pilot ignition system activates properly each time for reliable startup.
-
Monitor Flame Quality – Inspect the burner flame regularly; it should be steady and blue for optimal combustion and energy efficiency.
-
Ensure Thermostat Accuracy – Calibrate and test the thermostat to ensure accurate temperature control and avoid unnecessary energy consumption.
-
Replace or Clean Filters – Clean or replace filters frequently to maintain smooth airflow and keep heating efficiency high.
-
Annual Inspection by a Professional – Have a licensed technician perform an annual inspection to ensure all components are functioning properly and safely.
