Heat Up Time Data
Heat Up Time To 120°F vs Initial Tank Water Temp. @ Ambient Air Temperature 75°F
Graph Description: A line graph showing the relationship between Inlet Tank Water Temperature (°F) on the x-axis (ranging from 40 to 100) and Heat Up Time (min) on the y-axis (ranging from 0 to 100). Multiple lines indicate different initial tank temperatures.
| Initial Tank Temp (°F) | Final Tank Temp (°F) | Heat Up Time (min) |
|---|---|---|
| 40 | 120 | 91.1 |
| 50 | 120 | 83.7 |
| 58 | 120 | 77.4 |

Installation Guidelines for Optimal Efficiency
All volume is cubic feet.
Installation Scenarios
- Not Ducted (Large Room): Room size larger than 1200 ft³ (e.g., 12' x 10' x 10'). Requirements: No additional ventilation needed.
- Not Ducted (Medium Room): Room size 400 ft³ (e.g., 5' x 8' x 10') to 1200 ft³ (e.g., 12' x 10' x 10'). Requirements: Full louvered door OR two louvers top and bottom. Minimum 2.9 ft² louver area.
- Ducted with Outlet Duct: Room size smaller than 400 ft³ (e.g., a closet). Requirements: Full louvered door. Minimum 3.25 ft² louver area. Insulate ducting to reduce condensation.
Insufficient air circulation may result in an ambient air temperature drop of more than 15°F (8°C) and inefficient operation. Refer to the room size volume illustrations to determine optimal installation and if exhaust should be ducted. Installation Space Volume is the unoccupied, free air space required for optimal operation. Additional objects occupying the space reduce total space volume.
Location Recommendation
For optimal operation, installation in the gray US map zone is recommended. When installing outside of the gray zone, consult your local plumbing contractor.
Minimum Clearances (Without Ducting)
| REAR | SIDES | TOP |
|---|---|---|
| 0" | 3" | 9" |
Average Ambient Air Temperature in January
Consideration should be given to ambient air temperatures below 37°F and above 37°F for optimal performance.
