TK JR. Combustion Air Supply Requirements
Air Supply From Outside Building
When combustion air is supplied from outside the building, an opening communicating
directly with the outside should have a minimum free area of one square inch per
15,000 BTUH input of the total input rating of water heater in the enclosed area.
Air Supply From Inside Building
When combustion air is supplied from inside the building, an opening communicating with
the rest of the dwelling should have a minimum free area of one square inch per 1000 BTUH
input of the total input rating of water heater in the enclosed area. These openings should
never be less than 100 sq. in.
Output Temperature Ratings of the Takagi T-K JR
The T-K JR Takagi On Demand Hot Water Heater is factory preset at 122°. You can change the output temperature
with the internal dipswitches to 113°, 122°, 140° or 182°.
If you want to use any other temperatures than this you can purchase the optional
Temperature Remote Controller (TK-RE02) that will allow the T-K JR to have output temperatures
from 99° to 167°.
Please Note: Hot Water Heater Temperatures over 125°F can
cause severe burns instantly or death from scalding. Children, disabled and elderly are at the highest
risk of being scalded. Feel water temperature before bathing or showering.
